SIGI · Analysis updated Nov 10, 2026, 6:00 PM ET
Why is Selective Insurance Group, Inc. (SIGI) stock moving?
No news items were published in the 14 days before Nov 10, so the only company-specific events are the Q3 2026 results 8-K (Oct 22) and the 10-Q (Oct 23). Neither filing text provided includes the reported figures, so the fundamental read is limited. The market data shows a clear post-results move: SIGI closed at $91.74 on Oct 22 and rose 5.3% to $96.61 on Oct 23 on 1.74M shares, well above the roughly 0.4M–0.8M daily volume seen before and after. Since then the stock has traded mostly between $98 and $105.65 (intraday high Nov 5), with a sharp reversal to $99.44 on Nov 6 followed by a rebound to a $103.34 close on Nov 10 near the session high. Volume has eased back to about 0.47M–0.75M per day, so the post-earnings interest has faded but not reversed. Overall the price trend is up roughly 12.7% from the Oct 22 close, but with no new news or disclosed earnings numbers to support it, the evidence for further direction is thin.

About Selective Insurance Group
Selective Insurance Group is a New Jersey-based holding company for 10 property and casualty insurers, all rated A+ by AM Best.

How it makes money
