#5 - Weeklys Are Listed on the Most Actively Traded Stocks
The list of Weeklys available changes each week. The CBOE wants to list options that will attract a great deal of trading volume. Thus, stocks that usually have high volume are on the list. In addition, stocks that are announcing news may be included.
You can find the list of Weeklys available on the CBOE Web site. Keep in mind that no new Weeklys are listed for expiration week for standard options (the third Friday of each month). In other words, there is no need for Weeklys when the “regular” options are down to their final week.
