NEW YORK (

TheStreet

eBay

and boosting call volume the same day RBC raised its target price to $29 from $24.

The out-of-the-money Oct. 26 calls changed hands more than 39,000 times today and were home to open interest of 1,066 contracts. These calls closed up 11 cents on the day. This computes to an implied volatility of 35.6.

The volume weighted average price of these calls was approximately 43 cents, meaning bullish investors who bought the Oct. 26 calls need EBAY shares to expire higher than $26.43 to make money. Keep in mind, of course, that the investor could choose to sell these options to take profit if the calls rise prior to expiration.

EBAY shares closed up 18 cents to $24.32 on Wednesday. The Oct. 26 calls have a delta of 29 cents, meaning for every dollar move in the underlying, these options should climb 29 cents. That means these calls

should

have moved 6 cents, but call-buying activity is pushing the prices higher.

Normal daily option volume in EBAY is approximately 22,000 contracts, and the call-buying action we've seen already trumps this figure. On Wednesday, approximately 53,000 contracts across all strikes hit the tape, more than half of which changed hands in the Oct. 26 call series.

Call-buying like this does not automatically mean investors should stock up on EBAY shares. The company's stock is currently up 53% higher from a recent low of $15.91, however, and at least one investor is looking for further upside throughout the next month.
