According to @godbole17, the VIX is showing signs of life as the Federal Reserve decision approaches, signaling a pickup in equity volatility into the FOMC window (source: @godbole17, X post dated Sep 16, 2025). The observation highlights event-risk conditions around the rate announcement that volatility-focused traders may monitor into the decision timing (source: @godbole17).

According to @StockMKTNewz, the S&P 500 has one more quarterly rebalance in 2025 with the announcement slated for Friday, December 5, setting a clear catalyst for potential index-addition trades (source: @StockMKTNewz). Traders typically monitor pre-announcement positioning and elevated closing-cross volumes around rebalances, as changes are implemented per S&P Dow Jones Indices’ published U.S. indices methodology and rebalancing procedures (source: S&P Dow Jones Indices U.S. Indices Methodology). Given periods of elevated equity-crypto correlation, desks should watch BTC and ETH for spillover volatility around the SPX event window and macro risk sentiment shifts (source: Coin Metrics research on equity-crypto correlation).
