Stocks open mixed following strong earnings

Wall Street opened mixed this morning, following yesterday's blowout Amazon earnings and this morning's solid Microsoft earnings.

In the first 15 minutes of trading, the Dow and the broader S&P 500 are both just underwater while the tech-heavy Nasdaq is up nearly nine-tenths of 1 percent, pushed higher by Microsoft and Amazon.

Amazon blew away expectations with strong sales across the quarter in earnings released after the bell yesterday. This morning, Microsoft beat expectations with its third-quarter earnings. I'll dive into those later today when updating our Third-Quarter Earnings Scorecard.
