Stocks Mixed After Big Tech Earnings; Market Rally Still Uncertain

Dow Jones futures edged higher after Microsoft and Alphabet earnings reacted to results. S&P 500 regained 200-day line.

Microsoft stock jumped on strong earnings, guidance, then pared gains. Google stock tumbled on earnings.

Visa fell on earnings. Boeing, Vertiv, CME earnings due Wednesday. Amazon edged lower late.

Market rally attempt still tentative. Earnings reactions generally positive so far.

Investors should stay engaged but not get too aggressive yet. Rally attempt still unproven.
