To give context to "the less I know" I studied economics (though don't work in that field) and follow financial press from interest. So my low knowledge is probably better than the average public. Based on this low knowlege trading on my broad stroke feelings, as much on gut as anything, and infrequent trading seem to work best. Previously I traded regularily (changing positions several times a week) and followed/analylised daily micro events within or affecting my target companies. I found I did worse and I was trying to understand market sentiment and buy/sell based on short term humps/dips.... which has no logic.
After a couple of years of mixed results, results have been much better by trading when I see those macro events when you feel to your bone the market has got it wrong. And then go in and wait a few months.
As a sample of one I cant say if this is right, and there are several industries that exist implying I'm wrong. But it absolutely works best for me.
