Market situation

Is it sign of market crash? So many US stocks suspended straight after opening xD

From Seeking Alpha this morning (

Once the market opens, NYSE circuit breakers work like this: trading halts for 15 minutes if the S&P 500 falls 7% (to 2,764) at any time before 3:25 p.m. ET. Another 15-minute pause is triggered if losses reaches 13% (2,586). If the decline hits 20% (2,377.9), markets will close for the day. With the exception of the final rule, circuit breakers are suspended during the final 35 minutes of trading.
