Short strategies for these sectors

Commodity stocks have been super stars in the past 3 months. Eventually, as US Dollar strengthens, these stocks will be fading out. Some big names of such stocks are:

Massey Energy, Chesapeake Energy, National Oilwell Varco.

What strategies we can use to benefit from these over-priced stocks? Short sells and purchasing puts. Writing covered calls can be another option if you don't mind holding such stocks for a long time (assuming you bought them very low).

Besides commonly recognized difference between short sells and put writing, short sells is a favorable approach in this stand because it is hard to predict what price it would fall at the put expiration. Considering how much money is involed in these star stocks, it is even riskier. Short sells, on the other hand, doesn't have time constraint.

Besides the above commodity stocks, VMWare and Amazon are two other stocks fall into this group. VMW has lately ousted their co-founder and lowered earning expectation. Amazon may be affected by weak economy.
