Why Microsoft and Shopify Stocks Jumped

That gain followed a run not seen in 26 years that wiped out losses for the year by early August. MarketWatch At that point shares were up about 0.8% for 2026 so far.

Shopify said sales for the third quarter should grow in the low-thirties percent range. Analysts had expected 26.3% growth. Reuters Its shares rose as much as 25% after that better-than-expected forecast. Bloomberg

In an earlier report, Shopify said it earned 48 cents per share after one-off adjustments. Analysts in a Bloomberg survey had expected 51 cents. Bloomberg

The broader context here is the order of events. Microsoft first got back above flat for the year from a small gain. Then it kept climbing over the next three months. For a giant company held widely in pensions and funds, that points to two things at once. Profit forecasts moved up. Investors also paid more for each dollar of profit.

In my view, the choice of stocks matters more than the size of the jumps. Investors wanted safer AI names with strong finances and a clear way to make money from AI. They did not buy every AI stock. Think of it like choosing sturdier boats in rough water. When money piles into those names, winners pull ahead and it is hard to keep up without them.

Looking at what this means for portfolios, the gap between forecasts is what counted. A low-thirties company forecast against mid-twenties expectations is a big gap. It forces analysts and computer models to update fast. A miss of one or two cents fades next to that. The safety check is plain. Does strong guidance last, do profit dollars keep growing, and do higher sales turn into higher profit? Gains stacked up quickly. Falls can do the same.
