I can&#8217;t find any other news that would explain the timing and which stocks were hit hardest.<\/p>\n<p>Here&#8217;s a sample of some of the harder hit stocks, all travel-related (Friday&#8217;s close compared to the highest close in February):<\/p>\n<ul>\n<li>-37% Hertz (HTZ)<\/li>\n<li>-36% Avis (CAR)<\/li>\n<li>-29% World Fuel Services Corp (INT)<\/li>\n<li>-24% Carnival (cruise line) (CCL)<\/li>\n<li>-22% Delta Air Lines (DAL)<\/li>\n<li>(compare to the S&amp;P 500: -12.4%)<\/li>\n<\/ul>\n<p>It is, of course, possible that the market was in a mild bubble in early February, and the virus merely triggered a return to sanity. There were enough high-priced stocks that I&#8217;ll guess that&#8217;s explains a little of what happened. Hertz and Avis are maybe high-risk stocks due to the risks associated with the upcoming transition to robocars. But the others that I listed did not at all fit my stereotype of overpriced stocks.<\/p>\n<p>And the stocks that I had been thinking were overpriced, in industries that don&#8217;t look to be especially hurt by the virus, declined roughly in line with the market.<\/p>\n<p>Outside of travel-related stocks, it mostly looks like a general shift in preferences to more cash, and away from stock. I.e. a general increase in risk aversion.<\/p>\n<p>The gold market is confused as to which direction a pandemic should move it. I agree. I&#8217;m confused as to how gold should react.<\/p>\n<p>What scenario could explain the decline? Maybe a two month shutdown of 90+% of U.S. air travel? A multi-year reduction in travel of 10%? It would take something like that for the market reaction to make much sense. Yet I&#8217;d bet at roughly 10:1 odds against any one of those scenarios happening.<\/p>\n<p>Metaculus is currently predicting <a href=\"https:\/\/www.metaculus.com\/questions\/3530\/how-many-people-will-die-as-a-result-of-the-2019-novel-coronavirus-covid-19-before-2021\/\">195k COVID-19 deaths<\/a> this year.<\/p>\n<p>Metaculus forecast trends ought to look a good deal like random walks, yet the charts I see there look more like exponential growth.<\/p>\n<p>Metaculus is likely to be a more objective source of information than the <s>news media<\/s> storyteller industry or social media. But it&#8217;s likely more susceptible to selection effects and hype than are markets that have lots of money at stake. (Metaculus has <a href=\"https:\/\/www.metaculus.com\/questions\/3667\/the-li-wenliang-prize-series-for-forecasting-the-covid-19-outbreak\/\">token prizes<\/a>, structured in a way that may encourage more extreme bets than a regular market would).<\/p>\n<p>None of this implies much about where other reactions to the virus are sensible. There&#8217;s a much different asymmetry between getting sick versus being paranoid than there is between losing money due to a pandemic versus losing money due to selling on a false alarm.<\/p>\n<p>I&#8217;ve got about a month&#8217;s supply of food, but that&#8217;s my normal preparation for a variety of disasters. I have no special insights about whether the current risks justify staying home.<\/p>\n<p>P.S. Chinese stocks are supporting the view that the situation in China has improved over the past month.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The stock market crash of the past two weeks looks like an over-reaction to COVID-19.
