Here we are on the Monday of expiration week. By Saturday morning, every December option either has to go to zero or get exercised. Even with all of the turmoil in the financial markets, that is one thing that still has to happen. It's like the sun coming up in the morning. So with that in mind, here is some activity from early trade today that demonstrates the expected ranges on some stocks between now and Friday's close.

Right out of the gate this morning, there was a seller of the

Google

(GOOG) - Get Report

December 300-330 strangle over 2,200 times for around $7.20, with the stock trading at $314. (A strangle means trading the 300 put and the 330 call at the same time.) Because the customer is short the 300 put and short the 330 call, it means he believes the stock will stay between 300 and 330 between now and Friday's close.

So what can we say about this put strangle sale? Since the customer took in $7.20 to make the sale, we can say that that is 2.3% of the stock price. It also means that the break-evens on the trade are $292.80 on the downside, and $337.20 on the upside. So the investor is betting that GOOG will not drop more than 7%, or rise more than 7%, by the close on Friday.

Another way to look at this strangle is relative to some other securities to see if the expectation is for more or less volatility. Take

JPMorgan

(JPM) - Get Report

, for example. With JPM trading at $29, the equivalent December strangle would be the 27.7 to 30.5 strangle. Since those strikes do not exist, we will look at a further out-of-the-money strangle, the Dec. 27.5 to 31 strangle.

It is currently bid 86 cents in the puts and 52 cents in the calls, for a total of $1.38, or 4.7% of strike. Because the strikes are further out of the money on a percentage basis than the Google strangle, we can safely say that for the next week, investors expect more volatility, and a wider range out of JPM than out of Google.

Expiration week is always a busy week for option traders, and it inevitably bleeds over into stock volumes as well. This simple example of looking at two strangles on two highly liquid large-cap stocks can give you insights into what traders are predicting for the different stocks for the week ahead. Due to the continuing financial turmoil, there is more volatility expected from a bank like JPM than from a tech bellweather like GOOG.
