Unum Group Shares Plunge 12.18% Amid $500M Trading Surge, Rank 247th in Volume

Unum Group (UNM) experienced a sharp decline of 12.18% on July 30, 2025, despite a 295.49% surge in trading volume to $0.5 billion, ranking 247th among stocks. The drop followed the insurer’s second-quarter earnings report, which revealed a 13.8% year-over-year decline in net income to $335.6 million and adjusted operating earnings of $2.07 per share, missing consensus estimates. Weakness in performance was attributed to underperforming segments and broader market pressures.

Recent institutional activity highlighted mixed signals for the stock. Large-scale investors, including AQR Capital Management and Dimensional Fund Advisors, adjusted positions, with the latter selling 940,093 shares. Conversely, BTC Capital Management and Private Advisor Group increased holdings, signaling cautious optimism. Analysts remained divided, with Jefferies raising its price target to $59.00 while UBS and others cut expectations following the earnings miss.

Strategic moves, such as Unum’s reinsurance transaction with Fortitude Re, and leadership changes, including the appointment of Andrew Walker as chief customer operations officer, underscored ongoing operational restructuring. However, these developments failed to offset investor concerns over earnings volatility and guidance that fell short of market forecasts.

The strategy of buying the top 500 stocks by daily trading volume and holding them for one day has delivered a 166.71% return from 2022 to July 30, 2025, outperforming the benchmark by 137.53%. With a compound annual growth rate of 31.89%, the approach highlights the potential of volume-driven strategies in capturing short-term liquidity-driven gains, though such tactics may not align with Unum’s recent performance trends.
