Objective read

The reaction, under the hood

The first regular session closed +10.21% from the pre-report close of $225.52. Volume ran at 2.61 times the prior 20-session baseline, which HPT classifies as elevated participation.

By session 20, MU was +60.85% while SPY was +3.02%. The +57.83% spread shows whether the move remained company-specific or faded back toward the broad tape.

Before the report, price was above its 55-day EMA and RSI measured 45.8. The first-session range was 1.50 ATR with the close at 19% of that session's range.
