• Goldman Sachs upgraded Research in Motion (NASDAQ:RIMM)saying to buy in front of EPS. I couldn't agree more and in fact was going to say that today. Be that as it may, I doubled my RIMM long into yesterday's weakness and plan to hold into/through EPS report. My quick take is that RIMM could have one of the better reports relative to all the negative analyst actions and commentary in tech and the overall market.
  
  
• One of my themes for this upcoming EPS season is to look for stocks that have had the most negative analyst commentary coming into the quarter, as no one these days is looking at things like Price/Sales, Price/Book or Price to normalized earnings.

Broadcom (NASDAQ: BRCM) reports tonight and it is getting hit due to the poor report from Qualcomm (NASDAQ: QCOM). QCOM lowered guidance quite a bit -- in fact, enough that I likely may not have to worry much about QCOM for the next couple quarters. Low $30's would present solid value.

Getting back to BRCM, I still feel it is one of the few must own chip names. I think it has enough innovation and diversification to avoid the 35-40% sequential reductions I am seeing from many in the chip space. However, I also think a lowering of the bar is priced into BRCM's shares and anything less than a disaster should keep the stock above $16.50 (assuming we avoid another shock down to the whole market). Anything around that level ($16.50) and lower would have me adding the shares. I've taken gains recently in trading shares and am hoping to add BRCM back on just a bit more weakness.

Analyst downgrades:

Qualcomm, Inc. (NASDAQ: QCOM), a famous name in the wireless industry whose colleagues include Broadcom Corporation (NASDAQ: BRCM), Texas Instruments Incorporated (NYSE: TXN), and Nokia Corporation (NYSE: NOK), reported earnings for the fourth quarter on Thursday. While the stock may be up today, I'm not so sure I'd be a buyer of it.

It's not that the bottom-line numbers were wholly bad. Net profit rose 16% to roughly $1.1 billion. Earnings per diluted share on an adjusted basis increased 17% to $0.63. According this news source, that figure beat estimates by three pennies. That's all well and good, but that news source also states that Qualcomm is guiding below consensus. Not surprising, certainly, given what the markets are going through. But it still puts a damper on the stock's near-term potential, in my opinion. Plus, free cash flow was down 13% during the quarter, and it was flat for the twelve-month period.

Except for certain companies like Microsoft Corporation (NASDAQ: MSFT), I'm not really interested in playing the tech sector. If you had purchased Qualcomm near its 52-week low of $30.87, I'd be a seller into today's strength. No, I certainly can't predict the movement of stock prices, but I can tell you that I think Qualcomm could easily pull back from today's rally. The recession is going to worsen, and I don't think we've reached the point where the market will begin to discount better days. In fact, we're probably far off from that point. The rally that is going on in the markets as I write this (and by the time this gets published, it could be gone for all I know) feels like a dead-cat bounce. That wouldn't be good for Qualcomm's stock, I'd imagine. So, kudos to management for beating Q4 expectations. But I won't be rewarding you by buying your stock. Sorry!
