Oil has staged a rally today of more than 5%. One reason for the rally is a continued pop in commodities following the Fed's announcements yesterday that it was going to buy Treasury bonds and mortgage-backed securities. The dollar fell dramatically, and that has caused gold and oil to rally. This rally has served to boost shares of commodity and energy stocks today.

Looking at the April 50 calls in Schlumberger ( SLB), we find that they have traded more than 17,000 times in the first three hours of trading today vs. current open interest of 2,453, for an average price of around $1.20. What is interesting about this call activity is that most of the activity is from buyers of the options.

In order for these calls to be profitable at expiration, the stock needs to be higher than $51.20, which is the strike price plus the option premium. Shares of Schlumberger are currently trading $45.22, up more than 4% on the day, and up more than 25% from their 52-week closing low of $35.19.

As I mentioned above, the majority of the trading was on the buy side, and that served to push up implied volatility. Last night, the calls closed at 60 cents vs. $42.91 stock. That was an implied volatility of 53. At the time that I write this, with the stock at $45.22, the calls are marked 1.30. That is an implied volatility of 57.

This buying activity in Schlumberger and other single stocks is helping to feed a rally in the CBOE Volatility Index ( VIX). Currently the VIX is up more than 6% on the day, rising from $40.06 to $42.60. This call-buying does not automatically mean that investors should run out and buy shares of Schlumberger. But it is worth noting that at least one investor thinks the shares could continue to run.
