Market crashes themselves don't matter at all in the grand scheme of things unless there's a complicating factor like a liquidity crisis. Is the underlying situation serious? Probably. Global growth is slowing and the end of artificially cheap money isn't good even if the cheap money was a bad idea in the first place. Those are my 2 cents. I've got also got several hundred thousand cents bet against the S&P. I'm worried about volatility, but not a steady rise in the short term.
