Microsoft Sits 12% Below Its High After the Largest One-Day Market Value Gain on Record. Here's What History Suggests Comes Next.

Microsoft’s shares surged on record-style scale, gaining 15.5% to $451.10 after its fiscal fourth-quarter report and lifting market value by about $450 billion in a single session. The quarter showed 18% revenue growth and guidance that Azure, its cloud platform, should grow about 45% in constant currency in fiscal first quarter. The move still came while the stock was down more than 18% for the year at the time of the report. Even after adding roughly another 8% since the record close near $487, Microsoft remains about 12% below its 52-week high of $553.72. A comparison to past mega-gainers suggests follow-through often depends on whether growth persists.
