I can see some similarities and they do both seem to attract a lot of the same people. But I think poker is more luck than the stock market is (as long as you study the fundamentals as well as the technicals.) I do not day-trade, but I do trade the stock market (more swing-trading and long term trades.) And just like playing good cards in poker, you can trade very good companies and still get blind-sided by something unexpected and loose a lot. But I still think the chances of that happening is a lot greater in poker than in the market.
