Everyone wants to be a genius caller of market changes. In some ways he's right. But not through some secret TA and genius analytical processes. Just statistics. Firstly, 100% of trends end. But secondly, the least likely way for a trend to end is for it to reverse. The faster and further trends travel, the more we think they are going to explode dramatically into an even faster decline, a crash, a burst, a pop, whatever you will - but its just not what they do.
e.g. The Wall Street Crash, the most famous, most persistent and most damaging(?) in history, the one that prompted so many stockbrokers to dive out of Manhattan windows, came out of a downtrend, not out of a market top.
So if we get anything other than a reversal into a downtrend within a few days, he's going to look just great.
