The reaction, under the hood

The first regular session closed -2.00% from the pre-report close of $73.10. Volume ran at 2.33 times the prior 20-session baseline, which HPT classifies as elevated participation.

By session 20, MU was -5.69% while SPY was +5.13%. The -10.82% spread shows whether the move remained company-specific or faded back toward the broad tape.

Before the report, price was below its 55-day EMA and RSI measured 46.7. The first-session range was 1.55 ATR with the close at 46% of that session's range.
