Therefore, they demand a premium as compensation for the greater risks and costs of investing in less-liquid securities. For example, liquidity risk partly explains the equity risk premium\u2014the average transaction costs on stock trades are larger than they are on Treasury bills, which can be traded in large blocks of tens of millions of dollars in a single transaction without affecting their price.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Academic research, including the 2015 study&nbsp;<a href=\"https:\/\/papers.ssrn.com\/sol3\/papers.cfm?abstract_id=2687047\">\u201cThe Pricing of Illiquidity as a Characteristic and as Risk,\u201d<\/a>&nbsp;published in the&nbsp;<a href=\"https:\/\/www.mfsociety.org\/modules\/modDashboard\/uploadFiles\/journals\/googleScholar\/1200.html\">September 2015 issue of the Multinational Finance Journal<\/a>, has found that the illiquidity premium in stocks is positive and highly significant worldwide after controlling for global and regional common risk factors (such as beta, size, and value). The research has also found that the market requires a higher premium for liquidity sacrifice in&nbsp;<em>negative<\/em>&nbsp;environments (for example, illiquidity increased during the great financial crisis), when investors holding illiquid equities become liquidity takers (divesting them, either to meet liquidity needs or due to panicked selling) and pay a steep price in doing so. In other words, the liquidity premium is conditional on the state of the market\u2014it\u2019s much smaller in good times and much larger in bad times.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The finding of a liquidity premium is consistent with economic theory, which holds that assets that perform poorly in bad times (when the marginal utility of consumption is higher) should carry large premiums. And what\u2019s more, illiquid stocks (which tend to be smaller stocks) have greater sensitivity to liquidity shocks and thus also should carry premiums (helping to explain the size premium). Stocks whose systematic liquidity risk rises more when funding illiquidity is worse have higher expected returns. The finding of a liquidity premium also holds for corporate bonds. Corporate bond illiquidity increases monotonically when moving from safer bonds to riskier bonds, helping to explain their incremental yield.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To summarize the theory and literature on equities and liquidity, investors care about stock illiquidity and thus demand higher expected returns on stocks that are more illiquid. Variations in illiquidity affect stock valuations. Thus, investors not only prefer assets that are more liquid, but they also prefer assets that have smaller exposure to liquidity shocks. In other words, they prefer assets whose prices fall less when market illiquidity rises, assets whose illiquidity rises less when market illiquidity rises, and assets whose illiquidity rises less when there is a market-wide decline in prices.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-diminishing-illiquidity\"><strong>Diminishing Illiquidity<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Of particular interest is that over the past 40 years we\u2019ve seen many technological (such as high-frequency trading) and regulatory changes (such as decimalization) that may have contributed to improving liquidity by lowering bid-offer spreads in financial markets. There may also have been impacts on liquidity caused by the dramatic expansion of the hedge fund industry, which now has more than $3 trillion in assets under management. It\u2019s possible that hedge funds, many of which are long-horizon traders and thus incur relatively small transaction costs, might have arbitraged away (or at least reduced the size of) the liquidity premium by buying illiquid stocks and short selling liquid stocks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Financial innovation, in the form of low-cost index funds and ETFs, may also play a role in the shrinking of the liquidity premium. Their presence allows investors to buy and sell illiquid assets indirectly lowering the sensitivity of returns to liquidity. These instruments enable investors to hold illiquid stocks indirectly while incurring low transaction costs, thereby reducing the sensitivity of returns to liquidity.&nbsp; For a more thorough understanding of this mechanism read&nbsp;<a href=\"https:\/\/alphaarchitect.com\/?p=64467\">my<\/a>&nbsp;or<a href=\"https:\/\/alphaarchitect.com\/2014\/12\/03\/trading-etfs-in-the-secondary-market\/\">&nbsp;Wes\u2019<\/a>&nbsp;prior post on ETF Liquidity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A diminishing illiquidity premium was found by\u00a0<a href=\"https:\/\/papers.ssrn.com\/sol3\/cf_dev\/AbsByAuth.cfm?per_id=762193\">Azi Ben-Rephael<\/a>,\u00a0<a href=\"https:\/\/papers.ssrn.com\/sol3\/cf_dev\/AbsByAuth.cfm?per_id=276421\">Ohad Kadan<\/a>, and\u00a0<a href=\"https:\/\/papers.ssrn.com\/sol3\/cf_dev\/AbsByAuth.cfm?per_id=32069\">Avi Wohl<\/a>, the authors of the 2015 study \u201c<a href=\"https:\/\/papers.ssrn.com\/sol3\/papers.cfm?abstract_id=1099829\">The Diminishing Liquidity Premium<\/a>,\u201d published in the\u00a0<a href=\"https:\/\/www.cambridge.org\/core\/journals\/journal-of-financial-and-quantitative-analysis\">April 2015 issue of the Journal of Financial and Quantitative Analysis<\/a><em>.<\/em>\u00a0They found that the characteristic liquidity premium had significantly declined over the past four decades. It was large and robust until the mid-1980s but had become small and \u201csecond-order\u201d since. In fact, they found that there was no longer a liquidity premium among NYSE and AMEX stocks. They also found that even for smaller stocks there was a characteristic liquidity premium in early periods, but it declined significantly and largely disappeared later, concentrated only among small stocks. Thus, to the extent that a characteristic liquidity premium currently exists in U.S. public equity, it\u2019s economically small. They also found that the decline in the liquidity premium stems from an improvement in liquidity. This finding is consistent with markets having become more efficient following more intense arbitrage activity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The authors noted that their results have important implications for equity valuations: \u201cA reduction of the average annual liquidity premium from 1.8 percent to 0 percent implies a very large price effect.\u201d All else equal, a smaller liquidity premium justifies a lower equity risk premium, providing support for higher valuations. They noted: \u201cA 1 percent decrease in the discount rate may translate into a 10 percent-20 percent increase in valuation.\u201d The decline in the liquidity premium may also help explain the shrinking of the small-cap premium, about which&nbsp;<a href=\"https:\/\/alphaarchitect.com\/2020\/12\/18\/is-size-a-useful-factor-or-not\/\">much has been written<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In terms of asset management strategies, their findings cast doubt on the liquidity-based long-short trading strategies that have become common for hedge funds. The authors did emphasize that their results were based on data from only U.S. stock markets. Our equity markets are probably the most liquid markets in the world, and it\u2019s likely that liquidity pricing is more significant in less liquid markets.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The above findings are consistent with those of the authors of the paper&nbsp;<a href=\"https:\/\/papers.ssrn.com\/sol3\/papers.cfm?abstract_id=2687047\">\u201cThe Pricing of Illiquidity as a Characteristic and as Risk,\u201d<\/a>&nbsp;published in the&nbsp;<a href=\"https:\/\/www.mfsociety.org\/modules\/modDashboard\/uploadFiles\/journals\/googleScholar\/1200.html\">September 2015 issue of the Multinational Finance Journal<\/a>, who found that there was a strong and persistent downward trend in illiquidity since the early 1970s. However, the trend had been interrupted from time to time by bear markets, during which illiquidity rises. For example, they found that while the rise in illiquidity during the 2008-2009 financial crisis was quite strong, by the close of 2014, illiquidity was lower than ever before.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is an important finding because the sharp decline in illiquidity over the recent decades provides at least a partial explanation for the rise in equity valuations. As trading costs fall, the level of the equity risk premium should be expected to fall as well, resulting in (or justifying) rising valuations. The narrowing of bid-offer spreads and the dramatic fall in commission costs have helped improve liquidity, resulting in a smaller equity risk premium.<\/p>\n\n\n\n<p
