Examining short interest activity and the CBOE Market Volatility Index (VIX)

by Bernie Schaeffer 5/7/2008 8:16 AM


The activities of the "new shorts" (and by this I mean an institutionalized, mainstream short-selling trade that is practiced by well capitalized hedge funds and traditional money managers) have been of great interest to me. It is by no means the case that you want to blindly "fade" their big positions by taking a contrarian bullish stance, as there have been numerous examples over the past year of heavily shorted stocks whose share prices have been (and continue to be) savaged by the market, due in no small part to the willingness of these deep-pocketed shorts to "double down" and add to their positions when they are working.

In addition, the new shorts are much less prone than they have been in years past to flee when positions move against them, so the short-covering rallies fueled by panicked short liquidation have become somewhat scarcer. That said, one need not look further than today's action to find an example of a short-covering panic, as shares of Ford - with a short interest of over 270 million shares and put open interest of 1.3 million contracts - surged by as much as 16% on a positive earnings surprise.

Last month, Joe Sunderman discussed in these pages the unprecedented bearishness reflected this year in the slant of the financial media, as evidenced by the astounding number of bearish magazine covers. He bluntly stated that "We have never seen such an onslaught of negative cover stories in all our years of tracking the market." I believe this "mega-bearish" media tilt reflects the likelihood that the bad economic news has already been reflected in this market, and that the upside potential from a combination of short covering and the movement of some of the now huge store of sideline money back into the market comfortably exceeds the downside risk.

It is also interesting to note the fact that the CBOE Volatility Index (VIX) has recently moved below its 32-week and 40-week moving averages after over a year of trading above these levels. In other words, just as the headlines are beginning to scream "fear," professional options traders are beginning to be a lot less fearful. And I'll go with the opinions of the professional options trading community over those of the headline writers any day of the week.
