The mechanical regularity of Silbermann's sales (identical share count every ~7 days) strongly indicates a pre-arranged 10b5-1 trading plan. This is not a discretionary signal. Monitor for any change in the sale pattern (size, frequency, or plan termination) which would signal a shift in insider sentiment.
