A trader purchased 800 of the June 370/350 put spreads at $1.90 per contract on average, Zhang stated.

The trader “is betting that this carnage is not over” and is risking about $150,000 in premium on the expectation of Costco Wholesale’s stock declining by as much as 18% by June expiration, he added.
