Having moved to the sidelines from mid-October until late November, insiders avoided the volatile and unprofitable month of November 2025 (S&P 500 off 0.6%, Nasdaq off 1.9%, Dow Jones Industrial Average up 0.02%, and Russell 2000 off 0.3%). But last week, we reported that insider-sentiment data from Vickers Stock Research showed a possible pivot, this as the one-week data calmed considerably. This week brings more of the same. With a sell/buy ratio from Vickers bullish at 2.00 or lower, all of the major one-week ratios from Vickers this week sport a three-handle. But that's much better than readings over the past month that were in the high-single digits and, at times, in double-digits. As well, the latest improvement in sentiment has started to have a beneficial impact on Vickers' longer-term (eight-week) ratios. Still, with the improved eight-week readings still at 3.83 (NYSE), 4.69 (Nasdaq), and 4.29 (all exchanges), insiders are not yet buying aggressively. Insider buying outpaced insider selling in three sectors over the past week. In both Consumer Staples and Real Estate, the sector sell/buy ratio came in at 0.6, while in Energy the ratio was 0.8. While each of these instances signal a greater number of purchases than sales during the week, the volume of transactions in these three sectors lagged the average for all sectors. Conversely, insider sentiment was the weakest in Information Technology, which saw a sell/buy ratio of 13.1 on meaningful transaction volume. Other notable sectors included Healthcare, with a sell/buy ratio of 4.1 on reasonable volume and Communications Services, with a sell/buy ratio of 4.3 on light volume. This week, analysts at Vickers highlighted insider transactions of interest at DoorDash Inc. (NGS: DASH) and Natera Inc. (NGS: NTRA).
