That prediction was made in early June. The market moved up pretty substantially right after the announcement.
The only Chinese wall is...............in China. Ah so. Wall Street's funk shun is SELLING paper. They devote 24/7 toward this endeavor. They don't like buying it back. But, at tiems, it's necessary when there's little to sell. As such, they have to get it to wholesale levels to shake it out.
At the time, their model was predicting a 14% drop over the next six months. It's not fair to "pooh-pooh" the prognostication by examining a sliver of the time frame in question. As for identifying a future period in which downside risk is greater than usual, I think they may be on to something. As you know, it's a probabilities game.
