Micron surges on memory chip boom — jump on the AI hardware rally

Verdict: Micron's earnings justify the thesis, but wait for the cross to confirm

Micron's fundamentals are doing the heavy lifting here: the quarter ended May 28, 2026 booked $41.5B of revenue (up 73.8% sequentially), $28.2B of net income, and $26.1B of free cash flow, with gross margin around 84.6% — numbers that give the AI-memory thesis real earnings support, not just narrative. But the trend trigger has not fired: the 9-day EMA at $945.49 still needs a confirmed daily-close cross above the 21-day EMA at $935.99, and the stock sits 671% above its range low, with net open-market insider selling of roughly $231M in the ownership filings for the period ended June 30, 2026 — a passed reporting deadline, so delayed positioning data rather than a current read. The strategy's own traded record is thin: one 12-month window, 7 trades, a 42.9% win rate, a 2.1% total return, and a 2.4% maximum drawdown, while the 24- and 60-month windows never triggered at all. Memory's cycle cuts both ways: gross margin swung from negative 4% in early 2023 to about 84.6% in three years, so a long-only trend rule gives back a lot when pricing turns. Wait for the EMA cross to confirm on a daily close; the fiscal 2025 numbers (115.3% revenue growth but diluted EPS down 76.9% year over year and a 22.8% net margin) are a reminder that the recent acceleration is new, late-cycle, and fast to reverse.

Trade now

MU closed at $958.16, with the 9-day EMA at $945.49 sitting about $9.50 above the 21-day EMA at $935.99. The entry condition is a daily close in which the 9-day EMA crosses above the 21-day EMA. The two lines are close together, so the cross can trigger on any day momentum firms — wait for it to confirm on a close before entering rather than buying the strength outright. Once triggered, risk is defined mechanically: the stop exits if price closes at or below entry minus 2.4 times the 14-day ATR, and the target exits at or above entry plus 3.6 times the ATR. That structure implies roughly 1.5 dollars of reward per dollar of risk. Position sizing is fixed-risk at 2% per trade with a 10% maximum position, so size the entry off the ATR-based stop distance. The completed 12-month backtest on this exact setup shows 7 trades, a 42.9% win rate, a 2.1% total return, and a shallow 2.4% maximum drawdown — a modest but controlled profile. Exits were filled on daily bars rather than intrabar, so treat exit quality as approximate. The longer 24- and 60-month windows produced no triggers, so the 12-month window is the relevant evidence. Note also the filing picture: net open-market insider selling of roughly $231M in the most recent ownership period is a live counter-signal against the momentum thesis. Concretely, waiting means: no position until the EMA cross confirms on a daily close, then enter with the ATR stop and target attached, and honor the cross-back-below exit if the trend rolls over before either level is hit.

The fundamentals behind the AI memory wave are real — and accelerating

The idea argues that AI hardware demand keeps Micron's sales surging and that riding the upward trend catches that wave. The reported numbers back the demand thesis hard. In the quarter ended May 28, 2026, Micron booked $41.5B of revenue, up roughly 74% from the $23.9B booked the prior quarter, with net income of $28.2B (up about 105% sequentially) and gross margin expanding to 84.6% from 74.4% one quarter earlier. Operating cash flow of $45.7B and free cash flow of $26.1B in that same quarter — after years in which Micron burned cash — give this rally an earnings foundation, not just a narrative.
