So, if the stock market is hypothetically predicted to crash in 10-25 days - what are you going to do? Short it now? Short it later? Buy? Just curious what HN readers think. For the giggles...I'm going short when the tape says market sell orders exceed the rate of bid additions, and the opposite for going long. I like long-term analysis as much as the next guy, I just never, ever, ever, ever, ever make decisions based on it.
