Nets being deployed for falling objects as the IMF, deflation, and creepy diseases assault stock prices. No greater minds than those at the IMF have declared markets too high and of requiring immediate correction. Many of the IMF members know a disaster when they see one since they have honed their prognostic skills on years of either over reacting or completely missing important events. This time they will not be fooled. The rich are not stupid all the time.
Markets have not become volatile yet but rather have been experiencing a kind of dull going down bid action. And who can blame reluctant Bears since downside follow through has been rare in the last few years as the markets have withstood the push to bite down hard because of the Fed's magic powers.
Down and ugly will make those of us who design alternative investment strategies much happier because it so much easier to beat something that is at zero. But stay calm. The old adage from my days in the pits was the trader axiom ; the market moves the most to everyone's disadvantage.
