Stocks slipped yesterday as the mood again soured on corporate earnings after software giant Microsoft warned of slowing growth.

The Dow Jones industrial average fell 33.35 points, or 0.31 percent, to close at 10,576.65, while the Nasdaq composite index fell 17.22 points, or 0.84 percent, to 2,029.37. The benchmark Standard & Poor's 500 index dropped 4.17 points, or 0.34 percent, to 1,210.85.

For the week, the Dow rose 0.36 percent, the Nasdaq fell 2.7 percent and the S&P 500 off 0.40 percent. Year-to-date, the Dow is down 1.95 percent, the Nasdaq off 17.9 percent, and the S&P 500 off 8.3 percent.

After Thursday's market close, Microsoft posted profits that fell within Wall Street estimates, but warned revenue growth would slow in the current quarter amid still-sluggish demand for personal computers.

Microsoft, a significant driver of the Nasdaq composite and part of the Dow, fell 4.7 percent, or $3.39, to $69.18. The Microsoft slide accounted for two-thirds of the Dow decline.
