Objective read

The reaction, under the hood

The first regular session closed +10.54% from the pre-report close of $82.03. Volume ran at 2.92 times the prior 20-session baseline, which HPT classifies as elevated participation.

By session 20, MU was +9.72% while SPY was -0.71%. The +10.43% 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 50.9. The first-session range was 1.22 ATR with the close at 88% of that session's range.
