Micron Beat Forecasts Twice. The Stock Went Opposite Ways.
Many big US companies report earnings right after the 4 p.m. close in New York, so the biggest price move often happens in thin after-hours trading. This article uses Micron as the worked example. In March 2026 it beat sales forecasts and still fell about 5% after hours, because it raised its spending plan by $5 billion. In June it beat again and jumped about 14.6% after the close. The lesson: prices react to the surprise against expectations, and guidance for the next quarter often matters more than the quarter just ended. It explains how earnings nights work, why the company’s own guidance sets the bar, how the timing converts to UTC+8, and uses a table to show how the same after-hours move eats different shares of margin at 10x and 20x leverage.
TL;DR
Many big companies report earnings after the 4 p.m. close in New York. The biggest price move often happens while most of Wall Street is logged off.
Micron beat forecasts in March and fell. It beat again in June and jumped about 15% after hours. The beat wasn’t the trade. The surprise was.
Before the next report, know what moves the price, and size for a jump either way.
Same beat, opposite move
On March 18, 2026, Micron, one of the world’s biggest memory-chip makers, reported sales of $23.86 billion. Analysts had expected about $20 billion. It was a clear beat.
The stock fell about 5% in after-hours trading. The reason: Micron also said it would spend $5 billion more that year on factories and equipment. Investors worried about what that spending meant for future profits.
On June 24, Micron beat again. Sales came in at $41.46 billion against forecasts near $35.7 billion. This time the stock jumped about 14.6% after the close.
Two beats. Two opposite moves. Same company, three months apart.
Why “beating” isn’t enough
An earnings report is a company’s report card for the last three months: how much it sold and how much it kept as profit.
Before the report, analysts publish forecasts. The stock price already reflects what traders expect. So the price doesn’t react to “good” or “bad.” It reacts to “better or worse than expected.”
Think of a student everyone expects to get an A. An A changes nothing. An A-plus with a note saying next term will be even better? That moves the room.
Three things usually matter most:
- The results vs. forecasts. Sales and profit per share against what analysts expected.
- The guidance. What the company says about next quarter. This often matters more than the past quarter.
- The plans. Spending, prices and demand. Micron’s March spending plan outweighed its beat.
Why it happens after 4 p.m.
The regular US stock session runs from 9:30 a.m. to 4 p.m. New York time. Many companies release results right after the close. That gives everyone time to read the numbers before the next full session.
But trading doesn’t stop. In the evening session, fewer people trade, so prices can jump in big steps, and the gap between buy and sell prices widens.
Micron’s report nights follow a pattern:
- Results come shortly after the 4 p.m. close.
- The call with analysts starts at 4:30 p.m. New York time. While New York is on summer time, that’s 4:30 a.m. the next day in Singapore and Hong Kong (UTC+8).
- The next regular session opens at 9:30 a.m. New York, 21:30 in UTC+8 in summer.
Before each report, look up the company’s guidance from the last one. That’s the bar traders measure against, along with what the company says about the quarter after.
A worked example
Take a $1,000 position in Micron at the close, before fees. Here are the two 2026 nights:
The dollar swing is the same in every column. Leverage only changes how much of your money it is. At 20x, a normal bad earnings night wipes out the margin, and liquidation comes even sooner.
Go deeper
Guidance beats history. The report covers a quarter that already ended. Guidance is the company’s forecast of the next one. Micron’s March and June reactions both turned on the future, not the past.

The first print can reverse. After-hours moves are made by fewer traders. In March, the drop deepened the next day, to about 6%. Early prices aren’t final prices.
Spending cuts both ways. Big factory spending can mean strong demand. It can also mean more supply later, and lower prices for the product.
The stock can carry the sector. Micron makes memory for AI data centers. Its report can move other chip stocks too.
Estimates move. Forecasts drift in the weeks before a report, so the bar on the day can sit above or below the company’s own guidance.
What this means for traders
- Know the bar before the report. Look up the forecast and the company’s own guidance.
- Listen for the future. The guidance and the call often move the price more than the headline numbers.
- Expect gaps. Thin evening trading can skip past your stop price.
- Size for the jump, not the average day. Earnings nights are not normal days.
- Convert the time. A 4 p.m. New York report lands at 4 a.m. in UTC+8 in summer, 5 a.m. in winter.
