A cross-market trading halt can be triggered at three thresholds: 7% (level 1), 13% (level 2), 20% (level 3). 15-min halt for L1&L2; market close for L3.
Note that it is measured by a single-day decrease in ***S&P 500 Index***, not $SPY (which is SPDR S&P 500 ETF Trust).
- S&P 500 is an index made up of the 500 largest US companies. We cannot buy S&P 500 index.
- SPY is an index fund that tracks S&P 500
The opening price for S&P 500 on 4/10/2025 is 5456.90, so the level 1 triggering point will be at 5094.91.
Good luck!
