The index is down about 3% since Tuesday's close and is down around 22% so far in 2022.
On Thursday afternoon, with the S&P 500 index-tracking SPDR S&P 500 ETF Trust's (SPY.P) shares down 0.6% to $372.56, the most heavily traded SPY contracts were those that would guard against the ETF's shares slipping below $370 by Friday.
SPY puts expiring at the end of next week, struck at the $350 mark, just above the ETF's mid-October intra-day low of $348.11, were the fourth most actively traded SPY options on Thursday.
"Recent 'Fed meeting volatility' has not necessarily been confined to the Fed day itself," Christopher Jacobson, a strategist at Susquehanna Financial Group, said in a note.
"Over the six prior Fed meetings year-to-date, the SPY has seen an average move of +/- 2.8% from the close on Wednesday (Fed day) to Friday's close," he said.
