If these solar stocks shoot up like crazy, and then drop like crazy, why is buy and hold the dominant strategy? It seems like it would be "sell when things seem good, and buy when things seem in-the-dumps". I feel like "buy and hold" is a good strategy when the stock moves up only a penny a day and so there's never any point in trading in and out of it. For solar, the true best strategy would instead be a rapid turn over buying the dips and selling the rips. For instance, buying two days ago into SPWR at 28+ and then selling as it approached 30, and then buying again at 28.00.
I'm just making a statement, not really doing the above. Maybe a bit with options (I sold puts when spwr hit 28.60 two days ago, then sold calls when spwr hit 30.01 yesterday). It just seems to me that buy and hold isn't necessarily the best strategy.
I'd be saying "buy right now and sell when it appears solar is looking good again".
