Basically for the past 4 months..... I identified 10-20 stocks I like, a lot. Love even. Or, at least the market does. I've bought on dips (as long as there is no news about THAT stock to explain it), and I've sold at 5% profit. This is money dedicated to this effort. I don't recommend this as a strategy for most / anyone else.....but it has worked VERY WELL this year. That's the kind of thing to do with maybe 10% of your portfolio.....the rest should be in long term plays. IMO, of course. As for the "too much money in too few stocks" rubbish. There is plenty of money flowing into the market, across plenty of stocks. There is no bad time to buy, if you have time on your side.
