NEW YORK (CNNMoney.com) -- A record plunge in prices of existing homes produced only a modest increase in sales in February, according to the latest reading on the battered housing market by an industry trade group released Monday.

The National Association of Realtors reported that sales by homeowners rose 2.9% in February to a seasonally adjusted annual pace of 5.03 million, up from January's reading of 4.89 million. It was the first month-over-month rise of the annualized pace since July.

"These are signs that housing's problems are being addressed, but I wouldn't break out the champagne yet," said Northern Trust chief economist Paul Kasriel. "We still have a ways to go."

Though February's pace beat economists' expectations, sales last month were still down 23.8% from a year earlier. Economists surveyed by Briefing.com expected the report to show existing home sales slowed to an annual pace of 4.86 million.
