• 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.
  

Analyst upgrades:

• Wachovia upgraded shares of The Goldman Sachs Group Inc (NYSE: GS) to Outperform from Market Perform on expectations for greater pricing power given Goldman's position as the largest remaining independent securities firm.
• Keefe Bruyette upgraded Investment Technology Group Inc (NYSE: ITG) to Outperform from Market Perform as they believe the company will take market share with the reshaping of the large wire-house brokerage community. The company's target was raised to $37 from $33.
• Broadpoint raised Hoku Scientific Inc (NASDAQ: HOKU) to Buy from Neutral as they believe the contract with Tianwei New Energy reduces financing risk.
• ACE Ltd (NYSE: ACE) and The Travelers Companies Inc (NYSE: TRV) were upgraded to Buy from Neutral at Goldman.
• Axcelis Technologies Inc (NASDAQ: ACLS) was upgraded to Buy from Hold and Evergreen Solar Inc (NASDAQ: ESLR) was lifted to Hold from Sell at Citigroup.

Analyst downgrades:

It has been a tough year for investors. We have been dealing with recession fears, housing market worries, high gasoline prices and a very weak U.S dollar. As much as we would love to say that the worst is behind us, we still could be in for some more rocky times ahead. So its best to try to figure out which stocks would be best to avoid for the time being.

Richard Gibbons wrote up a nice piece over on The Motley Fool that looks at some of the stocks that we would be wise to stay away from at this time. Regardless good or bad times, he is convinced there are always ways to make money, but in order to find the winners, it is also necessary to pull out the losers.

So how can we separate out the winners from the losers?

Gibbons seems to have a simple answer for this. He believes there is really no use in wasting our time trying to separate the winners from the losers as there are so many great cheap stocks that could offer us a chance to make money. Gibbons' advice is to not choose ugly and risky companies that could put our hard earned money at risk. To makes this clear, he uses a baseball analogy, expressing his options for the curve balls instead of the fastballs.

The exchange stocks have been hot issues in the past few quarters as investors have been betting on increased trading activity from hedge funds, higher volatility, and so on.

But just this week, exchange stocks have received a beating harder than the markets as a whole. I believe that if a snapback rally occurs next week, these stocks should bounce back harder than the overall market. Two particular exchange stocks have appealing charts: CME Group (NYSE: CME) and NYSE Euronext (NYSE: NYX). Both of these charts display similar characteristics, as you can see below:
