No, you can't. Stocks have an underlying value, and the stock price will not deviate very much from what the company is expected to earn. Currencies can get some of this, but because the market participants knows that governments can change their economic policies to stabilize the value, it will seldom get really bad. The best comparison is probably gold, which behaves pretty much as I described. There are enough participants in that market to make the cycles much longer than for bitcoins, though.
