FYI: While our friends in the bond market are all enjoying the third day of a three-day weekend, US equities are operating on a typical schedule for Columbus Day. Given the bank holiday and the fact that most schools are closed in the NYC region, this is often a day where liquidity is a bit more scarce than normal. A perfect example of that lack of liquidity causing major outsized moves was in 2008 when the S&P 500 rallied more than 11% on Columbus Day. Granted, that was a period of historic volatility, but there have only been a handful of such large one-day moves in market history, so even for the financial crisis, an 11.6% one-day move was a big deal. As good (or bad if you were short) as that move felt in 2008, the gains were fleeting and were more than erased within just seven trading days!
