That is because the true Dogs of the Dow .... are no longer in the Dow. And some of them are just plain no longer solvent.
Both May and Aug were heavy (as heavy as bull markets go) drops in the market, so it seems to me, he is good. Were they the "top" top? No, but you could make money based on those calls.
Your analysis is terrible, every single short he posted failed and got stopped out. Not a single one of them made a cent. You could, for instance, of traded my 3200 call by end of year issued in June and made far more money then anything he's posted on here in 2019. I have no idea why some of you think he is "good" his 2019 performance is terrible.
My previous top calls have resulted in a S&P decline of 190+ points. While my longer term swing objectives were not reached on some of the calls, you are brave if you think this one is any different. Good luck my friend
