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.
