Traders buying Mamma.com as play on AOL's new OpenRide

If you think it is hard to trade information like the release of OpenRide from AOL by trading the parent, you may be accurate. Time Warner (TWX) is a behemoth consisting of so many parts that it often gets difficult to trade the stock on each piece of news and you have to look for more of a general "good" grouping or "bad" groupiing of news on most days. But trading its partners and competitors is fair game when you see secondary and tertiary cause and effect.

Look no further than Mamma.com (NASDAQ:MAMA), trading up more than 30% at $1.86. Mamma's Copernic Desktop Search of Copernic Technologies is one of the search powers behind the new OpenRide.

What is odd is that an article from RedHerring.com was dated late Oct. 3, and the MAMA stock started to move a bit only late yesterday. Its average daily volume was only about 90,000 and yesterday it traded 448,100 shares. It closed up $0.20 to $1.36 yesterday, so it isn't exactly a huge stock and its market cap is now just over $25 million. Shares of MAMA have now crossed 1.25 million shares and it is up another 30% on the day (to $1.85 as of 11 a.m.). That $25 million market cap was only $16 million yesterday morning and it is so small that this may not even qualify as a micro-cap.

Mamma.com (MAMA) was one name that had been touted in the past after Mark Cuban briefly took a stake in the company, and sold for a quick profit. The have "The Mother of All Search Engines," as well as the Mamma Career Search and the Mamma Health search.

The company has a 52-week stock trading range of $0.86 to $5.15, so it isn't a name without volatility when it has news. Its September short interest was only listed as 92,987 shares.

If you compare the two services you will see the similarities.
