【7.21 Evening Strategy】 | Micron (MU) pre-market deep analysis + short-term trading execution strategy

I. Market view & pre-market data interpretation

1. Price overview
Yesterday’s close: 865.46; current pre-market intraday high reached 926.77, last price 919.32, with the biggest pre-market gain close to 7%.
The prior key resistance at 901 has been effectively broken; that former resistance has turned into an important support.
Pre-market intraday feature: after spiking to 926, it consolidated and pulled back—clear pressure. Overhead selling pressure has started to show; this is a high-gap-up spike then oscillating digestion of floating profit, not a one-way continuous squeeze.
2. News-driven catalyst
Core catalyst: Morgan Stanley upgraded to a bullish rating + expectations of improved AI storage demand; capital is betting that the storage cycle is recovering.
⚠️ Key qualitative point: it is still defined as an oversold rebound, not a trend reversal. In the long-to-medium term big-cycle downtrend structure, nothing has changed. A news-driven sentiment lift will make it easy for the stock to run into profit-taking as it spikes.
3. External environment risks
Volatility in the US stock market is amplifying, and tech stocks are highly correlated. Sentiment in the memory/storage sector is split; once the broader market weakens, the pullback力度 for stocks that rebounded from high levels will intensify. After a big gap-up, there are two paths:
① pull back to confirm support; stabilize, then challenge the prior high again;
② meet resistance under pressure; gap-up then fall, and pull back deeper.

II. Key price levels

🔴 Resistance levels
First resistance: 926.77 (pre-market high)
Second resistance: 932~936 (daily strong resistance zone)

🟢 Support levels
First support: 901~905 (upper edge of the former box; core divide between bulls and bears)
Second support: 883 (secondary strong support)

III. Short-term trading plan

✅【Priority plan: buy on a pullback (best risk-reward)】
Wait for the open; buy the pullback into the 901-905 zone. Look for intraday stabilization and do not enter if it quickly dumps.
Stop loss: 898 (if it effectively breaks down, abandon the long idea directly)
Take-profit plan:
Reduce half the position around 920; use the remaining position to push at 926.77, and if it breaks through, target 932~936.
If it touches 926 and can’t break through after repeated attempts, exit fully.

❌【No trading: blind chasing longs above 920】
The pre-market rally is huge; chasing at high levels has a very poor risk-reward. If it comes under pressure and pulls back, it’s easy to get trapped.
Only if there is high volume and it continuously holds above 927, then consider following with a very small position. Stop loss: 920. Target: around 932.

⚠️【Alternative: test short under pressure (small position only; not the main recommendation)】
At the open, keep probing the 926.77 high and it fails to break through; if there is high-volume stagnation and long upper shadow signals
Short with a small position; stop loss 930
Targets: first look at 910, second target the 901 support zone; when it reaches the support area, decisively take profit and do not expect a continued big drop.
