Tech Earnings Live Blog

NEW YORK (TheStreet) -- IBM(IBM) , Microsoft(MSFT) , Intel(INTC) and Google(GOOG) will give investors valuable insight into the health of the tech sector on Thursday when the Silicon Valley heavyweights report their quarterly results. Join out live blog at 3:30 p.m. ET.

With clouds of uncertainty gathering over the global economy, for example, investors will be closely monitoring IBM's comments on enterprise spending, particularly in debt-mired Europe.

IBM is amongst the tech giants reporting quarterly results on Thursday.

Microsoft and Intel, however, will also shed light on consumer spending patterns, most notably in the under-pressure PC market.

Intel recently lowered its fourth-quarter revenue forecast, citing weakness seen from the floods in Thailand. The tech bellwether, though, said that PC sales are expected to be up sequentially in the fourth quarter.

Internet giant Google is expected to report revenue of $8.407 billion and earnings of $10.49 a share after market close on Thursday. Google posted revenue of $8.44 billion and $8.75 a share in the same period last year.

As always, Google's Traffic Acquisition Costs, better known as TAC, will be a key number for investors. TAC is the amount of money that the search giant pays to other sites for their traffic, and came in at $2.07 billion, or 25% of advertising revenues, during the prior year's quarter.
