PCE, Powell Loom Large: Rising VIX Could Signal Market Jitters Ahead of Key Events

 | Mar 28, 2024 03:36AM ET

The stock market had a wild ride yesterday. It traded sharply higher in the morning, gave it all back, and ripped into the close.

The on-closing imbalances have played a role in the last two days of trading, but yesterday, the imbalance was just $650 million on the buy side and certainly didn’t contribute to moving higher.

I think the most likely answer is that the 5,215 puts for expiration yesterday were among the most actively traded options and likely served as a “put wall” for 0DTE.

Heading into the day's end, traders likely started to sell their puts to take their gains. It is easy to see the spike in the volume after 15:00.
