Market Sentiment: Options Activity for May 3, 2010

A reasonable gauge of market sentiment is the Put/Call Ratio. This is the ratio of the volume of put options to the volume of call options. Alternatively, open interest can be used in the calculation, as opposed to volume.
The ratio has become a commonly used indicator to determine if investors are bearish or bullish on a particular investment. When the Put/Call ratio is greater than 1 it is indicative of a bearish sentiment with Puts exceeding Calls. Conversely, a ratio less than 1 would mark a bullish sentiment with Calls exceeding Puts.
Contrarians use this ratio as a market timing indicator by gauging investments that may be overly bearish (high ratio) as a sign that the market is close to bottoming and buy on the expectation of a rebound. Conversely, if the market has become overly bullish (low ratio) investors would interpret this as an indication that a top is near and sell as a result. The ratio is more indicative when greater than 1, bearish sentiment, as it is more common that investors purchase call options over puts.
