For example: No one at the beginning of the year had a clue that the Dow Jones Industrial Average<br \/>\n        DJIA,<br \/>\n        <bg-quote field=\"percentchange\" format=\"0,000.00%\" channel=\"\/zigman2\/quotes\/210598065\/realtime\" class=\"positive\">+0.16%<\/bg-quote><br \/>\n       was about to turn in its worst first-half performance since 1962.  Since then, many investing experts have predicted the end of the market\u2019s slide. So far they\u2019ve been outright wrong or extremely premature.<\/p>\n<p> It\u2019s possible that your favorite indicator indeed has stopped working. But simple bad luck is the more likely explanation for why it <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>ears to be out of synch with the market.<\/p>\n<div class=\"paywall\">\n       Such frustration occurs in every bear market. When the market\u2019s major trend is down, the winner is who loses the least. So while it can seem that the market has suddenly become inscrutable, all that\u2019s really happened is that we\u2019re in a bear market.<\/p>\n<h6><span class=\"ez-toc-section\" id=\"Be_real\"><\/span><strong>Be real<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h6>\n<p>I was reminded of this at a seminar earlier this week led by Dan Villalon, principal and global co-head of the Portfolio Solutions Group at AQR Capital Management. Villalon reported on research which measured the likelihood that a market-beating strategy will hurdle various performance measures.<\/p>\n<p>He focused on a hypothetical investment strategy with a Sharpe Ratio of 0.50. The Sharpe Ratio is a measure of risk-adjusted performance, and a 0.50 ratio is ahead of the stock market itself, whose Sharpe Ratio historically has been closer to 0.40. The chart below reports what he found.<\/p>\n<div data-layout=\"inline\n                \" data-layout-mobile=\"\" class=\"\n          media-object\n          type-InsetMediaIllustration\n            inline\n  article__inset\n          article__inset--type-InsetMediaIllustration\n            article__inset--inline\n  \"><\/p>\n<figure class=\"\n        media-object-image\n        enlarge-image\n        img-inline\n        article__inset__image\n      \" itemscope itemtype=\"http:\/\/schema.org\/ImageObject\"><\/p>\n<div style=\"padding-bottom:67.28571428571428%;\" data-subtype=\"photo\" class=\"image-container  responsive-media article__inset__image__image\">\n        <img decoding=\"async\" srcset=\"https:\/\/images.mktw.net\/im-575323?width=540&amp;size=1.4849187935034802 540w, https:\/\/images.mktw.net\/im-575323?width=620&amp;size=1.4849187935034802 620w, https:\/\/images.mktw.net\/im-575323?width=639&amp;size=1.4849187935034802 639w, https:\/\/images.mktw.net\/im-575323?width=700&amp;size=1.4849187935034802 700w, https:\/\/images.mktw.net\/im-575323?width=700&amp;size=1.4849187935034802&amp;pixel_ratio=1.5 1050w, https:\/\/images.mktw.net\/im-575323?width=700&amp;size=1.4849187935034802&amp;pixel_ratio=2 1400w, https:\/\/images.mktw.net\/im-575323?width=700&amp;size=1.4849187935034802&amp;pixel_ratio=3 2100w\" sizes=\"(max-width: 639px) 100vw, (max-width: 979px) 620px, (max-width: 1299px) 540px, 700px\" src=\"https:\/\/images.mktw.net\/im-575323?width=700&amp;height=471\" alt=\"\" title=\"\">\n      <\/div><figcaption class=\"wsj-article-caption article__inset__image__caption\" itemprop=\"caption\">\n      <\/figcaption><\/figure>\n<\/p><\/div>\n<p>       In any given trading session, the chances that this market-beating strategy will outperform risk-free cash are just 51%. That\u2019s barely better than a coin flip, confirming that the market\u2019s daily gyrations are largely random. But notice that the odds don\u2019t grow dramatically as you extend your investment horizon. At the quarterly horizon, Villalon found, there\u2019s a 60% chance the strategy will beat cash over any randomly picked three-month period. At the yearly horizon, the odds are no better than 69%. Only at the 10-year horizon do the odds rise to 94%.<\/p>\n<p>The investment implication: Investors need to develop realistic expectations about what is achievable. Even when they are lucky enough to be following a market-beating strategy, over individual days, weeks, months, quarters and even years they still should expect to underperform not just the market, but cash.<\/p>\n<h6><span class=\"ez-toc-section\" id=\"Benefit_of_the_doubt\"><\/span><strong>Benefit of the doubt<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h6>\n<p>The corollary of this investment implication: Lagging the market and underperforming cash is not a reason to believe your strategy or indicator is no longer valid.<\/p>\n<p>This was shown by a study several years ago by University of Chicago finance professor Eugene Fama and Dartmouth professor Ken French. In their study, which appeared in the <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.cfainstitute.org\/en\/research\/financial-analysts-journal\/2018\/faj-v74-n3-6\" class=\"icon none\">Financial Analysts Journal in 2018<\/a>, they found that, over periods as long as a decade, there\u2019s a considerable chance that market-beating strategies will lose.<\/p>\n<p>To reach this conclusion, the professors ran the following simulation: In each of 120 consecutive months, assume that a strategy\u2019s return is equal to what it was in a randomly selected month from the past five decades. Running this simulation 100,000 times, they calculated how often the strategy lagged the market.<\/p>\n<div id=\"cx-membership-tile\"><\/div>\n<p>To illustrate, consider the value investment style, which picks stocks with low ratios of price to fundamental value (as opposed to growth stocks, which trade for high ratios). Even though value has handily beaten growth over the past century, through the end of 2021 it had famously lagged for at least a decade \u2014 the longest sustained period of lagging performance in the historical record. <\/p>\n<p>Fama and French found that this is not surprising: In their simulations, 10-year losses for the value strategy occurred 9% of the time. The odds of a loss over even a 20-year horizon, while smaller, are still \u201cnon-trivial\u201d \u2014 due to nothing more than luck alone.<\/p>\n<p>The bottom line? As French put it to me in an interview several years ago, when an indicator or strategy appears to stop working, \u201cstatistical noise \u2014 luck, in other words \u2014 is always the first possibility to consider.\u201d<\/p>\n<p><em>Mark Hulbert is a regular contributor to MarketWatch.
