Well, all right then. Giddy up!
I think this “guru” makes his money from publishing predictions, not from buying and selling stock.
My one experience from trying to time the market was when I sold a bond fund to buy stock funds after three weeks of down market. The following three weeks the market dropped more than the prior three weeks. I decided trying to time the market was a suckers bet and have stayed with reinvesting dividends since then.
