Aflac Shares Plunge 0.62% as Trading Volume Surges 31% to Rank 453rd

On October 13, 2025, Aflac (AFL) closed with a 0.62% decline, trading at a volume of $0.22 billion—a 31.29% increase from the previous day—ranking 453rd in trading activity among listed stocks. The insurer’s shares faced downward pressure amid broader market volatility, with analysts noting elevated short-term trading interest in the sector.

Recent filings highlighted Aflac’s Q3 earnings guidance, which aligned with consensus estimates but omitted commentary on long-term policyholder retention metrics. Investors appeared to price in uncertainty around the company’s ability to offset rising claims costs amid persistently low interest rates. Short-term technical indicators showed bearish divergence on 10-day and 20-day moving averages, amplifying near-term bearish sentiment.

Back-testing of a 1-day RSI <30 bounce strategy on NVIDIA (NVDA) from January 1, 2022, to October 13, 2025, revealed a negative cumulative P&L and suboptimal risk-adjusted returns. This outcome suggests standalone RSI-based signals may lack reliability in volatile markets, with potential improvements requiring extended holding periods, trend filters, or hybrid signal integration for robustness.
