Everyone is gearing up for Intel Corp. (NASDAQ:INTC) earnings after today's close, here's a preview of earnings expectations.

The Advanced Micro Devices, Inc. (NYSE:AMD) price war has long been known and doesn't really change anything for this last quarter. What might be an issue is the guidance based on even a deeper price war, but there haven't been any serious estimate cuts on Intel from bulge-bracket firms on Wall Street.

Tomorrow we have Apple Inc.(AAPL) ($0.78 estimate), and here is a full earnings calendar for the week.

Herzfeld Caribbean Basin Fund, Inc. (NASDAQ:CUBA) is deemed as the backdoor play to investing in Cuba if Fidel Castro's health is truly deteriorating even further.

Symantec Corp. (NASDAQ:SYMC) is trading down 8%, and Doug has a piece outlining its real exposure to a Microsoft threat. I have previously noted that Symantec broke its chart after its previous earnings warning, and this appears to have it set even more so that way. CIBC has downgraded Symantec, and Goldman Sachs has removed it from the prized Conviction Buy List.

Doug also noted that the Cisco Systems Inc. (NASDAQ:CSCO) downgrades might not be the best call out there, and I also noted after the analyst call how different this company is today from two years ago when the stock couldn't keep up with its valuations. The research isn't noting a risk to current earnings per se, so we aren't looking for anything grossly different. If you are a tech bull, then the 3% drop today might just be a gift.
