• I've taken a leg in the Ultra QQQ ProShares (AMEX: QLD). The market has popped 2% off lows, the question is will it pop the full 7%?
  
  
• I'm seeing a few positive divergences and the percentage of stocks below the 50 day moving average is well below the 2002 levels. I haven't looked at the percentage of stocks below the 200 day, but I'm sure the reading should be equally distressed.
  
  
• I know people are pricing in earnings per share Armageddon in tech land -- so the question is, what happens to many of these stocks if it's really just sort of "punk" and not a total cataclysmic drop in revenue guidance.

Research in Motion (NADAQ: RIMM) volatility Elevated as RIMM closes at Record High.

RIMM is recently trading up 22 cents to $78.80 after completing a 3 for 1 stock split. RIMM is expected to report EPS on 10/4. TD Newcrest says "with AT & T (NYSE: T) having launched Apple's (NASDAQ: AAPL) iPhone with an unlimited data component costing $20/month, and believe Verizon (NYSE: VZ) and Sprint Nextel (NYSE: S) are likely to respond with price cuts to Blackberry Internet Service. This would be positive catalysts for RIMM because they would likely sell many more devices to price sensitive customers." RIMM over all option implied volatility of 50 is above its 26-week average of 41 according to Track Data, suggesting larger risk.

F5 Networks (NASDAQ: FFIV) volatility of 55 above 26-week average of 44.

FFIV, a provider of content switching application traffic solutions, is recently up $0.98 to $36.54 in pre-open trading. FFIV completed a 2 for 1 stock split on 8/20. Wedbush Morgan say's "we advise investors to remain on the sidelines as we believe the acquisition of Acopia introduces significant risks into the business." FFIV over all option implied volatility of 58 is above its 26-week average of 44 according to Track Data, suggesting larger price fluctuations.

Wall Street's judgment was swift and brutal. On news of the $210 million acquisition for Acopia Networks, F5 Networks' (NASDAQ: FFIV) shares plunged 13% to $72.43.

F5 Networks develops sophisticated technologies to streamline the delivery of web applications. As networks get more congested, it's become a very lucrative market segment.

But F5 wants things to get even bigger – and hopes the deal for Acopia will be a big boost. In fact, it's F5's largest transaction in its history.

Basically, Acopia allows for enhanced management of computer files. The technology is known as file virtualization and has the potential for being a big market. Acopia not only helps make things more efficient, but even deals with things like compliance.

While it's tough to determine the size of Acopia – which is privately held – it does look like the company is still fairly small. Currently, there are about 100 customers.

What's more, the transaction is expected to be dilutive to F5's earnings, which is usually a no-no for Wall Street.

There are also some worthy competitors like Cisco Systems (NASDAQ: CSCO) and EMC (NYSE: EMC).
But, with the strength of F5, Acopia will have a better footing when trying to get new contracts.

More importantly, it does look like Acopia has standout technology (and a great management team). But the big question remains: Is there a need for the products? It's not clear that it's a must-have and that could be what's worrying investors.
