Goldman Sachs published its “Americas: 2009 Software Outlook” report today and it’s as dismal and ugly a forecast as you’d expect, given the current economic climate.

“The worst of the IT-spending slowdown likely remains in front of us, as we start the clock on slashed 2009 budgets,” Goldman said in the report. “We forecast 0 percent revenue growth for our group, below consensus at 5 percent, and 1 percent earnings growth, below Street at 2 percent.”

Beyond that, the firm forsees an eight percent decline in developed economy tech capital investment, with the likes of Microsoft (MSFT), Oracle (ORCL), SAP (SAP), Symantec (SYMC), CA (CA)–the so called Big 5–treading water until the economy recovers. Said Goldman, “We expect the Big 5 software companies…to benefit from more defensive revenue streams due to critical nature of functions, ‘stickier’ maintenance, stronger negotiating leverage, and a likely spending consolidation to larger vendors. Hence, we assume 0 percent growth for this group in 2009.”

Ugly. Could have been worse, though.
