You should certainly try to test any edge you think you have, and look for missing information. If you develop a good edge it’s easy to make some profit, but it’s always easier to lose money if you’re careless. But don’t give up before you even try.
Yep, I agree with all of this. I guess I way I would phrase it is that we don’t start with a flat prior: we have mountains of evidence that most investors underperform, and that finding an edge is difficult. Doesn’t mean it’s not possible, and absolutely you should try, so long as you’re taking very careful steps not to fool yourself about performance, benchmarking appropriately, etc.
On the ‘open secrets’ - I’m writing a big effort-post right now, and this is one of my main points of confusion - would appreciate your input once it’s up.
