And it&#8217;s not just exotic stocks that are affected, but also well-known and established Swiss companies. <\/p>\n\n<p>The <strong>Swatch Group<\/strong>, once a popular stock on the Swiss stock exchange, has lost around 70% of its value since its high in November 2013 &#8211; as the chart clearly shows.  <\/p>\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1854\" height=\"1218\" src=\"https:\/\/schweizerfinanzblog.ch\/wp-content\/uploads\/2018\/11\/Chart_SwatchGroup.png\" alt=\"swatch group Chart; Diversification\" class=\"wp-image-16543\" srcset=\"https:\/\/schweizerfinanzblog.ch\/wp-content\/uploads\/2018\/11\/Chart_SwatchGroup.png 1854w, https:\/\/schweizerfinanzblog.ch\/wp-content\/uploads\/2018\/11\/Chart_SwatchGroup-768x505.png 768w, https:\/\/schweizerfinanzblog.ch\/wp-content\/uploads\/2018\/11\/Chart_SwatchGroup-1536x1009.png 1536w\" sizes=\"(max-width: 1854px) 100vw, 1854px\" \/><figcaption class=\"wp-element-caption\">Swatch Group share price performance since 1997: Despite interim highs of over CHF 600, the share price at the beginning of 2026 is below the 2006 level (Source: Google Finance, April 2, 2026) <\/figcaption><\/figure>\n\n<p>The worst case is even more drastic: bankruptcy. <strong>Swissair<\/strong>, once the nation&#8217;s proudest airline, had to stay on the ground in October 2001 &#8211; shareholders lost everything. Investors in <strong>Credit Suisse<\/strong> did not fare much better: Once one of the largest banks in the world, it was taken over by UBS on an emergency basis for little money in March 2023 following a crisis of confidence. Shareholders lost practically everything.   <\/p>\n\n<p>Incidentally, the opposite of stock-picking is not necessarily passive investing &#8211; even actively managed funds often hold hundreds of stocks and are therefore broadly diversified. The actual counter-concept is the <strong>concentration on a few stocks<\/strong>. And it is precisely this concentration that increases risk &#8211; without increasing returns.  <\/p>\n\n<p>But concentration is not only evident in stock picking. Anyone who keeps their entire assets in a savings account is also concentrating on a single form of investment &#8211; with the difference that the threat here is not price losses, but a creeping loss of purchasing power due to inflation. And the compound interest effect, which makes the decisive difference in the long term, has virtually no effect. We showed how big this difference is over decades in <a href=\"https:\/\/schweizerfinanzblog.ch\/en\/invest-instead-of-saving-money\/\">lesson 1<\/a>.   <\/p>\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><\/p>\n<\/blockquote>\n\n<p>You can find out how diversification solves this risk &#8211; and what the science says about it &#8211; in the next chapter.<\/p>\n\n<h2 class=\"wp-block-heading\"><span id=\"What_is_behind_diversification_The_theory_in_a_nutshell\">What is behind diversification? The theory in a nutshell <\/span><\/h2>\n\n<p>This brings us to Harry Markowitz&#8217;s <a href=\"https:\/\/en.wikipedia.org\/wiki\/Modern_portfolio_theory\" target=\"_blank\" rel=\"noreferrer noopener\">Modern Portfolio Theory (MPT)<\/a>. He was awarded the Nobel Prize in Economics in 1990 for his groundbreaking doctoral thesis. <\/p>\n\n<p>Markowitz was the first to provide theoretical proof of the positive effect of diversification on the risk and return of an overall portfolio. The core of his theory is the distinction between <strong>systematic<\/strong> and <strong>unsystematic risk<\/strong>.<\/p>\n\n<p>All securities on the market are subject to systematic risk &#8211; i.e. market risks such as interest rate rises, recessions or political instability. It cannot be diversified away and is simply the price of investing itself. <\/p>\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><\/p>\n<\/blockquote>\n\n<p>The unsystematic risk, on the other hand, is the company-specific risk &#8211; such as management errors as in the VW emissions scandal. This risk can be reduced through diversification. And that is the key point: the market compensates you for the systematic risk &#8211; but not for the unsystematic risk. So if you invest in individual stocks, you are taking on unnecessary risk without being able to expect higher returns.   <\/p>\n\n<blockquote>\n<p style=\"text-align: center;\"><strong><span style=\"color: #37c392;\">&#8220;<\/span><\/strong>Company-specific risk can be reduced through diversification &#8211; market risk cannot.<strong><span style=\"color: #37c392;\">&#8220;<\/span><\/strong><\/p>\n<\/blockquote>\n\n<p>You will achieve the strongest diversification effects if you combine investments with the lowest possible <strong>correlation<\/strong>. The range extends from +1 (same development) to 0 (independent development) to -1 (opposite development). Within the equity asset class, typical correlations are between 0.70 and 0.95 &#8211; the effect is real, but limited. The combination of different asset classes brings significantly more, as we will see below.   <\/p>\n\n<h3 class=\"wp-block-heading\"><span id=\"The_efficiency_line_what_makes_an_optimal_portfolio\">The efficiency line: what makes an optimal portfolio<\/span><\/h3>\n\n<p>Markowitz not only showed that diversification reduces risk &#8211; he also specified the minimum amount of risk that must be taken for a given return. The result is the <strong>efficient<\/strong> frontier. <\/p>\n\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">The efficiency line is created by plotting all conceivable portfolio combinations in a diagram &#8211; with the risk on the x-axis and the expected return on the y-axis.<\/p>\n\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">Portfolios on the curve are <strong>efficient<\/strong>: they achieve the maximum possible return for a given risk. Portfolios below the curve are <strong>inefficient<\/strong> &#8211; too much risk for too little return. Portfolios above the curve are simply not achievable.  <\/p>\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/schweizerfinanzblog.ch\/wp-content\/uploads\/2026\/04\/Schema_mit_Effizienzlinie_EN.png\" alt=\"Diversification_Efficiency_Line\" class=\"wp-image-16619\"\/><figcaption class=\"wp-element-caption\">Not every portfolio is equally good: the blue dots show inefficient portfolios &#8211; they deliver too little return for the risk taken. The relationship between risk and return is only right on the red efficiency line. Three points stand out: the MVP (minimum variance portfolio) at the lower end with the lowest risk, the MEP (maximum return portfolio) at the upper end with the highest return and in between the tangential portfolio &#8211; the portfolio with the highest return per unit of risk taken.  <\/figcaption><\/figure>\n\n<blockquote>\n<p style=\"text-align: center;\"><strong><span style=\"color: #37c392;\">&#8220;<\/span><\/strong>Diversification is the only free lunch in investing: same expected return &#8211; but less risk.<strong><span style=\"color: #37c392;\">&#8220;<\/span><\/strong><\/p>\n<\/blockquote>\n\n<p>A global equity ETF such as the <strong>FTSE All-World<\/strong> is close to the MEP &#8211; the maximum return portfolio at the upper end of the efficiency line. A single stock such as the Swatch Group, on the other hand, lies to the right of the curve: with the same or even lower expected return, you bear significantly more risk &#8211; without being compensated for it. This is precisely the &#8220;free lunch&#8221; of diversification: not more return, but less risk with the same expected return.  <\/p>\n\n<h2 class=\"wp-block-heading\"><span id=\"Diversification_in_practice_8211_two_stages\">Diversification in practice &#8211; two stages<\/span><\/h2>\n\n<p>Theory is nice &#8211; but how do you put diversification into practice? And how far do you have to go? The old stock market adage that you shouldn&#8217;t put all your eggs in the same basket comes in two stages. But first you should fulfill an important prerequisite.   <\/p>\n\n<p><strong>The nest egg.<\/strong> Before you invest, you should keep a bank balance of three to six months&#8217; expenses as a liquidity reserve. This reserve serves to cushion unforeseen expenses &#8211; due to job loss, illness or repairs &#8211; without you having to touch your investments. Paying off any <strong>consumer loans<\/strong> also has priority, as their interest rates exceed any realistic return on investment. Only once you have built up this reserve and are free of consumer debt can you really invest the rest of your assets for the long term.  <\/p>\n\n<h3 class=\"wp-block-heading\"><span id=\"Level_1_8211_Diversification_within_the_equity_asset_class\">Level 1 &#8211; Diversification within the equity asset class<\/span><\/h3>\n\n<p>Let&#8217;s start with the most important level: broadly diversify shares. A simple rule of thumb helps with orientation: <\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>No-go: individual shares<\/strong> <br\/>If you only hold one share, you bear the full company-specific risk. Total loss &#8211; as with Swissair &#8211; is not a theoretical scenario. <\/li>\n\n\n\n<li><strong>Suboptimal: few Swiss stocks<\/strong> <br\/>Many people tend to overweight domestic stocks &#8211; the so-called home bias. Understandable, but structurally problematic: the Swiss market is heavily concentrated in three sectors (pharmaceuticals, financials, consumer goods) and accounts for less than 3% of global market capitalization. <\/li>\n\n\n\n<li><strong>Recommended: Global and cross-sector<\/strong> <br\/>A global ETF on the FTSE All-World or MSCI ACWI comprises thousands of companies from all over the world. The company-specific risk is practically eliminated &#8211; and you simply don&#8217;t care whether individual companies rise or fall in the index.   <\/li>\n<\/ul>\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/schweizerfinanzblog.ch\/wp-content\/uploads\/2026\/04\/Diversifikation-chart_Einzeltitel_Index_EN.png\" alt=\"\" class=\"wp-image-16616\"\/><figcaption class=\"wp-element-caption\">Global beats Switzerland beats CH stocks. Swatch Group is down after 20 years &#8211; while the broad global index has more than tripled the capital invested. A clear argument for global diversification in the portfolio. (Source: Own presentation based on stock market data from Google Finance \/ SIX; period January 6, 2006 to March 31, 2026; SMI and Swatch Group in CHF, FTSE All-World in USD; excluding dividends, not adjusted for inflation)   <\/figcaption><\/figure>\n\n<h4 class=\"wp-block-heading\"><span id=\"Caution_limited_cluster_risk_also_in_ETFs\">Caution: limited cluster risk also in ETFs<\/span><\/h4>\n\n<p>Anyone who buys an <strong>MSCI World ETF<\/strong> and thinks they are perfectly diversified should take a closer look: Around 70% of the index is made up of US equities, of which over 20% is made up of the seven largest technology companies alone (&#8220;Magnificent Seven&#8221;). In addition, the MSCI World only covers developed markets of large and medium-sized companies &#8211; <strong>emerging markets<\/strong> such as China, India or Brazil are not included. If you want real geographical diversification, you have two options: either supplement the emerging markets component with a separate ETF, or invest directly in an MSCI ACWI or FTSE All-World, which already include emerging markets. If you want to go one step further, add a <strong>small-cap ETF<\/strong> to your portfolio &#8211; and thus also include smaller companies.   <\/p>\n\n<p>The legislator also has diversification rules: For <strong>UCITS funds<\/strong> &#8211; the standard structure of most ETFs available in Switzerland &#8211; the so-called <strong>5-10-40 rule<\/strong> applies: individual positions exceeding 5% of the fund assets may not account for more than 40% in total. UCITS is not a must, but a quality feature designed to protect investors. Other ETFs &#8211; such as those that track the best-known Swiss index SMI &#8211; do not meet the requirements, as Nestl\u00e9, Novartis and Roche together regularly make up more than 50% of the index. So if you want to invest in a well-diversified way, you should pay attention to the UCITS label.   <\/p>\n\n<h4 class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"><span id=\"Excursus_Currency_risk_8211_an_issue_for_Swiss_investors\">Excursus: Currency risk &#8211; an issue for Swiss investors<\/span><\/h4>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">If you invest globally, you automatically invest in foreign currencies &#8211; around 60% of a FTSE All-World consists of US dollar securities. The decisive factor here is not whether you buy your ETF in CHF or USD, but in which currency areas the companies in the fund operate. <\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">Is that a reason to forego global diversification? No. In the long term, the diversification benefits clearly outweigh the disadvantages, and currency fluctuations are partially balanced out over time. Currency-hedged ETFs do exist, but they cost more and eat into returns in the long term. For most investors with a long-term horizon, the currency risk is simply bearable &#8211; and part of the package.    <\/p>\n<h4><span id=\"Conclusion_on_diversification_level_1\">Conclusion on diversification level 1<\/span><\/h4>\n<p>In combination with a solid liquidity reserve in your bank account, you are already well positioned with level 1 &#8211; a global equity ETF covers the most important aspects. But if you want to go one step further &#8211; reduce fluctuations or tap into additional return opportunities &#8211; you can combine different asset classes. This is level 2.  <\/p>\n\n<h3 class=\"wp-block-heading\"><span id=\"Level_2_8211_Diversification_across_asset_classes\">Level 2 &#8211; Diversification across asset classes<\/span><\/h3>\n\n<p>The combination of different asset classes is even more effective than diversification within equities &#8211; because their correlations with each other are significantly lower than within the equity asset class. While equities from different markets still have correlations of 0.70 to 0.95, the correlations between equities and other asset classes are often significantly lower &#8211; in some cases close to zero or even negative. The lower the correlation, the greater the diversification effect.  <\/p>\n\n<h4 class=\"wp-block-heading font-claude-response-body break-words whitespace-normal leading-[1.7]\"><span id=\"Bonds\">Bonds<\/span><\/h4>\n\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"><a href=\"https:\/\/schweizerfinanzblog.ch\/en\/obligations-simply-explained-all-facts\/\" target=\"_blank\" rel=\"noopener\">Bonds<\/a> often move in the opposite direction to equities &#8211; in times of crisis, bond prices rise when everyone is looking for safety. However, this is not always the case: in 2022, both equities and bonds fell massively in value when the central banks drastically increased interest rates.  Bonds are therefore not a panacea, but can be a valuable portfolio anchor over long periods of time. <\/p>\n\n<p>A classic example is the 60\/40 portfolio: 60% global equities, 40% bonds. For decades, this has been a proven starting point for people with a balanced investment approach &#8211; more stability, but also lower returns than with pure equity investments. Anyone with a long investment horizon and a focus on maximum growth will find bonds to be a drag on returns. The right weighting ultimately depends on the individual risk profile &#8211; precisely the topic of the next lesson.   <\/p>\n\n<h4 class=\"wp-block-heading text-text-100 mt-2 -mb-1 text-base font-bold\"><span id=\"Alternative_investments_as_an_admixture\">Alternative investments as an admixture<\/span><\/h4>\n\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">Anyone wishing to expand their portfolio beyond traditional asset classes will find further sources of diversification in the area of alternative investments &#8211; with different return, risk and liquidity profiles.<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Real estate<\/strong><br\/><a class=\"underline underline underline-offset-2 decoration-1 decoration-current\/40 hover:decoration-current focus:decoration-current\" style=\"font-size: revert;\" href=\"https:\/\/schweizerfinanzblog.ch\/en\/real-estate-etfs-the-easiest-way-to-invest-in-concrete-gold\/\" target=\"_blank\" rel=\"noopener\">Real estate ETFs<\/a><span style=\"font-size: revert; color: initial;\">  are the most accessible entry into &#8220;concrete gold&#8221; &#8211; without a mortgage, condominium owners&#8217; association or administrative expenses.

People with a more balanced investment approach can also supplement the core with bonds.  <\/li>\n\n\n\n<li><strong>Satellite<\/strong> <strong>&#8211; optional 0-30%<\/strong> <br\/>There is room here for targeted positions &#8211; individual countries or sectors, <a href=\"https:\/\/schweizerfinanzblog.ch\/en\/worthwhile-factor-investing\/\" data-type=\"post\" data-id=\"1934\" target=\"_blank\" rel=\"noreferrer noopener\">factor ETFs<\/a>, individual shares or alternative investments such as real estate ETFs, P2P lending, collectibles or cryptos. These positions can beat the market, but they don&#8217;t have to. Their loss does not jeopardize the overall portfolio.  <\/li>\n<\/ul>\n\n<p>The key advantage: you keep the discipline of diversification at the core without sacrificing the joy of active investing. And you always know what is at stake. <\/p>\n\n<h2 class=\"wp-block-heading\"><span id=\"The_honest_flip_side_diversification_vs_concentration\">The honest flip side: diversification vs. concentration<\/span><\/h2>\n\n<p>Here&#8217;s a point that financial blogs often fail to mention because it seems to undermine the main message. But it is part of the truth: <\/p>\n\n<p><strong>Exceptional returns come from concentration, not diversification.<\/strong><\/p>\n\n<p>Warren Buffett achieved his excess returns by betting massively on a few carefully selected companies. Private equity funds also outperform the market &#8211; if they do &#8211; through concentrated bets. Anyone who had bet everything on Nvidia or Apple in the past would be rich today.  <\/p>\n\n<p>That sounds tempting &#8211; but it is not a realistic path for the vast majority. And for one simple reason: <strong>concentration not only increases the opportunities, but also the risks.<\/strong> For every Buffett, there are hundreds who have backed the wrong horse and suffered total losses. Excess returns through concentration require sound analysis, a robust psychological profile, a lot of time &#8211; and above all a considerable amount of luck.  <\/p>\n\n<p>For most private investors, diversification is therefore not the path to super returns &#8211; but it is the path to solid, risk-adjusted returns over decades. And that is exactly what sustainable wealth accumulation means in practice. <\/p>\n\n<p style=\"text-align: center;\"><span style=\"color: #37c392;\"><i><em>&#8211; Partner offers &#8211;<\/em><\/i><\/span><\/p>\n<p class=\"has-text-align-center\" style=\"text-align: center;\"><em>Still looking for the right financial solution? <a href=\"https:\/\/schweizerfinanzblog.ch\/en\/our-recommendations\/\" target=\"_blank\" rel=\"noopener\">Our recommendations<\/a> &#8211; with attractive starting bonuses.<\/em><\/p>\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/schweizerfinanzblog.ch\/en\/our-recommendations\/\" target=\"_blank\" rel=\" noreferrer noopener\"><img decoding=\"async\" src=\"https:\/\/schweizerfinanzblog.ch\/wp-content\/uploads\/2026\/02\/Our-Favourites_1-1.png\" alt=\"Recommendations EN\" class=\"wp-image-15756\"\/><\/a><\/figure>\n\n<p class=\"has-text-align-center\" style=\"margin-top: 0cm; text-align: center; background: white;\" align=\"center\"><em><span style=\"font-size: 13.0pt; font-family: Montserrat; color: #37c392;\">&#8211; &#8211; &#8211; &#8211; &#8211;<\/span><\/em><\/p>\n\n<h2 class=\"wp-block-heading\"><span id=\"Conclusion\">Conclusion<\/span><\/h2>\n\n<p>Diversification is not a lazy compromise &#8211; it is the only proven &#8220;free lunch&#8221; in investing: same return potential, less risk. If you accumulate individual securities, you take on unnecessary risk without any corresponding return compensation. And if you park your assets in a savings account, you avoid price fluctuations &#8211; but you pay a different price: gradual loss of purchasing power due to inflation and lost compound interest.  <\/p>\n\n<p>Even the first stage &#8211; a global equity ETF combined with a solid liquidity reserve &#8211; forms a solid foundation. If you want to go further, you can also diversify across different asset classes &#8211; with a sense of proportion. <\/p>\n\n<p>The core-satellite approach combines the best of both worlds: a stable foundation thanks to diversification and scope for targeted positions thanks to controlled concentration.<\/p>\n\n<p>In the fourth lesson of this financial guide, we start right here and look at <a href=\"https:\/\/schweizerfinanzblog.ch\/en\/asset-allocation\/\" target=\"_blank\" rel=\"noreferrer noopener\">asset allocation<\/a> &#8211; in other words, the question of how you distribute your total assets across the various asset classes in line with your individual risk profile.<\/p>\n\n<p>You can find an overview of all the lessons here: <a href=\"https:\/\/schweizerfinanzblog.ch\/investieren\/\" target=\"_blank\" rel=\"noopener\">Learning to invest &#8211; in eight lessons<\/a>.<\/p>\n\n<h2 class=\"wp-block-heading\"><span id=\"This_might_also_interest_you\">This might also interest you<\/span><\/h2>\n\n<link rel=\"stylesheet\" href=\"https:\/\/schweizerfinanzblog.ch\/wp-content\/themes\/schweizerfinanzblog\/components\/post-list-component\/post-list-component.css\">\n\n<div class=\"post-list-componenet pt-2 pb-4\">\n\t<div class=\"row\">\n\t\t\t\t\t\t\n\t\t <div class=\"col-xl-6\">\n\t\t\t <a class=\"text-decoration-none\" href=\"https:\/\/schweizerfinanzblog.ch\/en\/asset-allocation\/\">\n\t\t\t\t<div class=\"d-flex post-list-card\">\n\t\t\t\t\t<div class=\"post-list-image \">\n\t\t\t\t\t\t<div class=\"image-wrapper\">\n\t\t\t\t\t\t\t<img decoding=\"async\" width=\"1920\" height=\"784\" src=\"https:\/\/schweizerfinanzblog.ch\/wp-content\/uploads\/2018\/11\/Asset-Allocation.jpg\" class=\"attachment-1920x1297 size-1920x1297 wp-post-image\" alt=\"Figure 5: Asset allocation is probably the most important success factor when investing money\" srcset=\"https:\/\/schweizerfinanzblog.ch\/wp-content\/uploads\/2018\/11\/Asset-Allocation.jpg 8981w, https:\/\/schweizerfinanzblog.ch\/wp-content\/uploads\/2018\/11\/Asset-Allocation-768x314.jpg 768w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/>\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div class=\"post-list-title px-2 d-flex align-items-center\">\n\t\t\t\t\t\t<p class=\"\">Asset allocation: the nuts and bolts of your investment<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t<\/a>\n\t\t<\/div>\n\t\t\t\t\n\t\t <div class=\"col-xl-6\">\n\t\t\t <a class=\"text-decoration-none\" href=\"https:\/\/schweizerfinanzblog.ch\/en\/rebalancing\/\">\n\t\t\t\t<div class=\"d-flex post-list-card\">\n\t\t\t\t\t<div class=\"post-list-image \">\n\t\t\t\t\t\t<div class=\"image-wrapper\">\n\t\t\t\t\t\t\t<img decoding=\"async\" width=\"1920\" height=\"1280\" src=\"https:\/\/schweizerfinanzblog.ch\/wp-content\/uploads\/2018\/11\/Rebalancing.jpg\" class=\"attachment-1920x1297 size-1920x1297 wp-post-image\" alt=\"Figure 6: Restoring the originally defined asset allocation with rebalancing\" srcset=\"https:\/\/schweizerfinanzblog.ch\/wp-content\/uploads\/2018\/11\/Rebalancing.jpg 3806w, https:\/\/schweizerfinanzblog.ch\/wp-content\/uploads\/2018\/11\/Rebalancing-768x512.jpg 768w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/>\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div class=\"post-list-title px-2 d-flex align-items-center\">\n\t\t\t\t\t\t<p class=\"\">Rebalancing: How to get your portfolio back on track<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t<\/a>\n\t\t<\/div>\n\t\t\t\t\n\t\t <div class=\"col-xl-6\">\n\t\t\t <a class=\"text-decoration-none\" href=\"https:\/\/schweizerfinanzblog.ch\/en\/worthwhile-factor-investing\/\">\n\t\t\t\t<div class=\"d-flex post-list-card\">\n\t\t\t\t\t<div class=\"post-list-image \">\n\t\t\t\t\t\t<div class=\"image-wrapper\">\n\t\t\t\t\t\t\t<img decoding=\"async\" width=\"1080\" height=\"620\" src=\"https:\/\/schweizerfinanzblog.ch\/wp-content\/uploads\/2020\/10\/Titelbild_Factor_Investing.png\" class=\"attachment-1920x1297 size-1920x1297 wp-post-image\" alt=\"Factor Investing\" srcset=\"https:\/\/schweizerfinanzblog.ch\/wp-content\/uploads\/2020\/10\/Titelbild_Factor_Investing.png 1080w, https:\/\/schweizerfinanzblog.ch\/wp-content\/uploads\/2020\/10\/Titelbild_Factor_Investing-768x441.png 768w\" sizes=\"(max-width: 1080px) 100vw, 1080px\" \/>\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div class=\"post-list-title px-2 d-flex align-items-center\">\n\t\t\t\t\t\t<p class=\"\">Is factor investing worthwhile?
