Microsoft's $450 billion jump

Microsoft had a great Thursday — its stock rose 16%, the biggest jump for the tech giant in nearly two decades.

• The resulting surge in market cap — $450 billion — was apparently the biggest one-day gain in stock market history, per Bloomberg's analysis.

Between the lines: Investors were grooving on the company's latest earnings report and the powerful growth of the Azure cloud computing business — a sign that its AI investments are paying off.

The bottom line: The cloud business is making it rain over in Redmond, Washington.
