Today I put 5% of my portfolio into PCL (Plum Creek Lumber) at $30/share. I chose to buy now because Plum Creek has not participated in the current rally; it's above it's March lows, but is currently trading near its April stock prices. The stock has a 5% yield and I believe lumber and mineral rights are an excellent hedge against inflation.
I also wrote four October $36 puts on MDT, paying $0.85 per share. I had puts on MDT expire un exercised last month; if the stock dips in the next six weeks, I may get it at a desirable price. If not, I'll continue to write puts for it; I want the stock, but not enough to pay $38/share for it.
