Concentrated insider selling cluster (6 insiders, 9 open-market sells, ~$7.36M) clustered on 2026-09-10/11, immediately following the 2026-09-08 merger agreement (8-K) with Central Service Corporation. All sales are open-market sells by directors, a co-founder, and a 10% owner at ~$33/share. The cluster is 100% sell-side with no buys, and the timing (3 days post-merger announcement) suggests insiders are monetizing on the merger premium. The cluster overlaps with a material corporate event (merger), which historically amplifies signal. However, the size is modest relative to the $12.9B market cap (~0.06%), and the sales are likely part of pre-arranged 10b5-1 plans or post-vesting liquidity, given the uniform pricing and same-day execution. The historical calibration for score=7 shows a negative expected alpha (μ_l -10.5% vs μ_w +8.8%), but the strong cross-filing amplifier (merger context + insider trades) and the high concentration of insider selling (6 unique insiders, including the CEO and co-founder) tilt the signal toward short-term downside.
