just my opinion, but I don't believe this is the time to be on margin in the market. The next several years are likely to be ones that try men's souls. Too much debt, too much of an upward trend to raise taxes, too much government interference, and did I mention TOO MUCH DEBT! I'm 30% cash, 20% gold, 20% raw material commodities, 15% shorting the S&P, and 15% tech (mostly some drug tech companies). My bias at this time is to be short inside the US, and long commodities outside the US - did I mention TOO MUCH DEBT?!! I do love the EZCH story, doubled my position Thursday afternoon, and am holding longterm. Also like CGEN, another techie Israeli drug company.
