What a brutal day for stocks.

The S&P 500 briefly traded down by 5.1% but has trimmed that to 4.8%. A 7% decline in the S&P 500 would trigger a 15-minute trading halt if it occurs before 3:25 pm ET. After 3:25 pm, trading continues unless a 20% decline is hit.

Technically, we're now testing the 61.8% retracement of the tariff rally from yesterday.
