About MSTR Market Moves
This page tracks unusual market activity for Strategy Inc Common Stock Class A (MSTR) across all trading sessions — pre-market (4:00 AM–9:30 AM ET), regular hours (9:30 AM–4:00 PM ET), and after-hours (4:00 PM–8:00 PM ET). A move is flagged as "unusual" when its Z-score reaches 2 or higher, meaning the price change is statistically significant relative to MSTR's recent daily volatility.
Z-score is calculated by comparing each move to the 20-day average return and standard deviation. A Z-score of 2.0 means the move is 2 standard deviations beyond the average — occurring in roughly the top 5% of daily moves. Relative volume (RVOL) compares current volume to the 20-day average volume at the same time of day, helping distinguish genuine institutional activity from noise.
