Chairman & CEO Mark Kowlzan sold $2.0M worth of PKG shares at $217.08, reducing his stake by 1.9% from a price 7.9% above the 90-day low. This matters because a CEO's first-ever open-market transaction is a notable data point, but selling near the low rather than buying creates a mixed signal without a clear cluster of other insiders for context. Bull case: if the stock holds above the $201.25 low and mixed analyst sentiment (9 buy / 7 hold) turns positive, a rebound toward the $232.90 high is possible; bear case breaks below $201.25.

Where it could go — No historical data for similar PKG signals; broad base rate for this signal type is 0.0% positive at 90d. Bull holds $201.25, bear breaks it.
