Chubb's $0.31B Volume Ranks 368th as Stock Falls 0.74% Amid Insurance Sector Scrutiny

On October 8, 2025, Chubb (CB) traded with a volume of $0.31 billion, ranking 368th among U.S. stocks. The insurer closed down 0.74%, marking a subdued performance amid mixed market conditions. The move came as investors digested a mix of sector-specific developments and broader economic signals.

Recent regulatory scrutiny in the insurance sector weighed on sentiment. A pending federal review of underwriting practices in property-casualty lines has prompted volatility across the space. Analysts noted Chubb’s exposure to high-risk commercial policies could amplify sensitivity to regulatory shifts, though no direct enforcement actions were reported against the firm.

Market participants also factored in earnings visibility. With Chubb’s Q3 results scheduled for release in early November, short-term positioning appears cautious. Positioning data showed a decline in open interest on index-linked derivatives, suggesting reduced speculative activity compared to the previous quarter.

To run this back-test rigorously I need a few extra details about how you’d like the portfolio constructed and valued: 1. Universe • Should the ranking be taken from all U.S. listed stocks (NYSE + NASDAQ + AMEX)? • Or a specific index/segment (e.g., Russell 3000, S&P 500, etc.)? 2. Entry / exit price • Enter at the next day’s open (after yesterday’s volume is known)? • Or at the same day’s close? • Exit one trading day later at the close, or the open? 3. Weighting & cash management • Equal-weight the 500 names each day? • Re-allocate 100% of capital daily (i.e., fully invested)? • Any transaction-cost or slippage assumptions? 4. Performance metrics • Besides cumulative return and annualized return, would you like max drawdown, Sharpe, etc.? Once I have those points I can retrieve the data, generate the daily portfolios, and run the back-test from 2022-01-03 (first trading day of 2022) through today.
