Dan Loeb of Third Point has come out publicly with a long list of other names like Ray Dalio, and Ron Paul. Of course, there are short seller funds out there that specifically look to profit from a companies stock price decreasing and this is not a panic piece. Short selling is necessary and Loeb is looking at specific targets, and acknowledges he does not believe, as some that we are nearing recession. It helps weed out awful companies, and allows people to punish companies that should be hit financially. I would not recommend running out and shorting companies. It is something that requires extreme due diligence. The natural, long term direction of the market is up, it is never a great thing to time the down, or recession.. Stepping in front of the Fed money printing machine is not a great idea. That being said take a step back, and take a bit more interest in your investments and consider a shuffle. Look at companies that make provide the resources to technology, infrastructure, energy and science instead of the companies that have already had massive growth. Shift your assets around a little.
