The Unusual Options Volume page shows the difference between the current volume and the average volume over the past month, highlighting unusual activity. The page shows the top 500 symbols (U.S. market) or top 200 symbols (Canadian market) ranked by 1-Month Volume Percent Change. Symbols must have a last price greater than 0.10.
We divide the page into three tabs - Stocks, ETFs, and Indices - to show the overall options volume change by symbol, and the volume made up by both calls and puts.
When an option has high volume activity, it usually indicates one of three things.
- It may indicate that a major event is about to take place. Traders are looking to cash in on an anticipated jump in the stock's price (one way or the other) and buy options as a result. In this case, you should look to compare the option's volume to the underlying stock's average daily volume. If the underlying stock has a large percent change in price AND a larger than normal volume, that is typically a strong market signal in the same direction as the change.
- Other times, high volume on an options contract may indicate that put buyers are hedging a potential downside risk for a stock whose technicals indicate a sell-off. Many times, these hedges are from a hedge fund or a large institutional trader. If you see high volume on an OTM option, this is usually driven by a hedge.
- And finally, high volume is sometimes generated by inexperienced options traders, traders who buy cheap OTM options with no specific reason and strategy.
High daily volume on an options contract warrants further analysis to try and identify where the trades are coming from. Once you understand which of the above three conditions are driving the activity, you can more effectively use that information to formulate your own strategy.
The page is initially sorted in descending 1-Month Total Volume %Change. You can re-sort the page by clicking on any of the column headings.
The Main View contains the following fields:
- Last: The last trade price of the underlying asset.
- Change: The difference between the underlying asset's current price and the previous day's settlement price.
- %Chg: The difference between the underlying asset's current price and the previous day's settlement price expressed as a percentage.
- Options Volume: The total options volume traded today across all options for the underlying Stock or ETF.
- 1M Vol %Chg: The percentage difference between the total options volume traded today, and the average options volume traded over the past 1-month.
- Call Volume: The total number of call options volume traded today.
- Put Volume: The total number of put options volume traded today.
- Put/Call Vol: The ratio of put options traded divided by call options traded. Typically a put/call ratio for stocks above 0.7 is considered a bearish signal as more traders are buying puts rather than calls. This implies that investors are anticipating the underlying stock to decrease in value. Conversely a put/call ratio for stocks below 0.7 is typically considered a bullish signal as more traders are buying calls rather than puts. This implies that investors are anticipating the underlying stock to increase in value. The more extreme the put/call ratio, the stronger the conviction of investors as to the potential move.
- The "Details" link will bring you to the symbol's Options Flow page, which can be used to estimate changes in market sentiment within specific time-frames. Analyzing this information can help you spot developing trends in long and short options trading activity.
