Michael Covel opens up by discussing a 2011 David Harding appearance on CNBC in his book Trend Commandments. The other day, now in 2014, Harding appeared on CNBC again with Joe Kernen. Covel goes over the clip, discussing CNBC’s policy of prediction and picks, their ignorance of Harding’s style and outlook, and the talking heads in general. Covel then went onto Twitter and posted, eliciting a response from Joe Kernen. Covel analyzes their Twitter exchanges, noting there are plenty of questions beyond what Kernen asked. Why does Harding enter? Why does he exit? How much does he bet each trade? Behavioral finance? Black swans? Trading only price action? It’s always fun to put a lance into the boil of the system and watch it pop, as Covel shows here. Covel surmises that either Kernen was not prepared, or there’s an agenda--it’s an acting job.
