I've been watching the big-cap rollover with acute pain. 3M (MMM)
That's because they have become the stocks to buy puts on when you think China's rolling over, but they trade wildly with the S&P during any S&P buy program like we had almost all day Monday.
Plus, it isn't like you get a chance to cover. These stocks all opened up a great deal and stayed up a great deal. There was barely a minute that you have a chance to cover.

Otherwise, your goose was cooked on most shorts.
That's the asymmetrical way the market trades. Individual stocks go down for specific reasons, but can easily rally for no reason other than the S&P as everyone knows that the biggest winners Monday had no real news flow.
I know this will sound strange, but we old-timers remember when things pretty much started at square one each day and you didn't get a gap open and you could buy stocks based on their fundamentals and not the ETF or SPX fundamentals. You still can, but usually not the day of impacts.
