With the coronavirus spreading panic and a market selloff over the last week, some are wondering how we should position our portfolios in light of a potential epidemic. As is usual under such circumstances, I prefer to take an historical perspective. Though history doesn't repeat itself, it certainly does rhyme and may give us a sound guide of how to proceed going forward. As such, I've attached a chart below which illustrates how the market has responded during the onset of other infectious diseases including SARS, Ebola and Avian Flu among others. Though such epidemics may certainly have an impact on the broader economy and market over the short term, you'll notice that over longer periods of time, the stock market has been "immune" to broader damaging effects.
Ignore the avalanche of TV commercials touting the money to be made using option strategies. The big money they refer to is for them, not you.
