Time for your daily dose of Trending Tickers, the stocks that you're tracking as measured by Yahoo Finance ticker searches:

Hertz (HTZ), don't it? The punchline to history's third best joke becoming less funny to investors watching the stock giving back this morning's gains. Bulls had reacted positively to the news that CEO and Chairman Tom Frissora is stepping down citing "personal reasons." Those reasons might include his personal distaste for getting yelled at by Carl Icahn who revealed an 8.5% stake in the company last month. Hertz recently withdrew guidance for 2014 due to accounting issues. Turnaround specialist Brian MacDonald will serve as interim head.

Twitter (TWTR) is up 3% on word that it's rolling out a test version of a "buy" button. Select users will be able to click and buy offerings from partners including Soundgarden, Home Depot or donate to groups like GLAAD and the Nature Conservancy. Users who click will enter their payment and shipping information which will then be sent along to the respective grunge bands, retailer or charitable organization. Twitter shares are up 50% over the last three months. In the interest of full disclosure I'm long the stock and that is not to be considered a recommendation or Re-Tweet.

Multimedia Games (MGAM) shareholders are shouting "Jackpot" on news that Global Cash Access Holdings (GCA) will be buying the company for $1.2 billion. GCA specializes in giving casino customers access to cash via ATMs, debit cards, checks or just about any other transaction requested. Combine that with a video slot machine maker and what do you have? About $800 million in revenue more than $200 million in profits and no moral finger-pointing from me. The deal is expected to close early next year.
