I disagree. Shorters keep getting the blame for low stock prices but let's take a look at what's happening in the world. The US continues to be bogged down in a recession it can't climb out of (no matter who becomes President). Europe is imploding and probably heading into it's own recession which will last a decade while it tries to resolve it's debt issues. China, well, who really knows what's happening there other than the fact that growth is lower than it once was. This is not an environment when commodities prosper and people rush out to buy stocks.
I do agree though that if Argex was able to close a good deal with PPG that that would have an enormous impact on the stock price. It still probably wouldn't take us to where we might otherwise be, but that's the difference between a bear market and a bull market. Nothing to do with shorts.
