You probably can't beat the market. But if you can beat a savings account earning 2% interest it's probably worth it for the learning experience.

Well, you'd have to beat 2% + transaction fees + capital gains which would mean you'd have to beat the market.

Not quite -- even if you match the market or slightly under-perform the market, it might still make sense if you achieve these results with lesser volatility and more consistent earnings. I do not necessarily want to beat a market which returns 7% on average but loses 40% every 6 years...
