In 2003 this relationship changed. Since that time the most notable up moves have taken place declining volume. As the bull market has progressed, the level of program trading has increased hugely along with other derivatives based volume. Very little stock could have been moving into strong hands. Quite a bit of stock could have been moving out of strong hands.
Short interest has grown astronomically throughout the advance.
Most traders believe that our financial markets are pristine. The rest of this post is for those who, like me, believe that they are anything but pristine.
This low volume environment has made it possible for anyone with a few bucks, to place a blanket of bids under the market and hold the market in place until short sellers panicked. Without ranting on about the probable source of the bids, I will just say that IMO, the last half of 2006 and most of 2007 to date happened because of blankets of bid being placed precisely for the purpose of causing short squeezes.
To make a long story even longer, I just want to say that I was surprised that there was no follow through today. When short squeezes start falling short of expections it may be a sign that the blanket bidders have gone to the well too many times.
