>> we could say that success in active investing is (often) a function of how much you're willing to spend to find the right opportunities

Is this also true at the level of the small investor ?

Say I'm willing to spend a few hours a day learning and researching about stocks. Does this mean that over time, I'll be able to significantly beat the index funds ?

Or is it, more likely, a fool's errand, because that as a small investor, I don't really have enough bandwidth and money to significantly diversify ?

It's a fool's errand. There are people who spend 80 hours a week doing this kind of analysis at firms that pay millions of dollars a year for the most sophisticated data and analysis, and those folks still don't beat the market more than randomly. These firms pay hundreds of millions of dollars to improve their trading systems' latency by just a few milliseconds.

You don't have a chance unless you are doing the same amount of work with more sophisticated tools, with the same trading tools.

You might win based purely on chance, but you are extremely unlikely to.

I'll just add my agreement. Fool's errand.

Some of the high frequency traders can rake it in. But they are using teams of highly paid analysts to look for opportunities and those opportunities don't last long before they have to move on to the next thing. And I would assume it's getting harder and harder for them as time goes on and more enter that market.
