Insider cluster: 2 insiders, $3.2M total
Actionable Insight • Neutral

This cluster is noise at TER's scale. CEO selling at the same price as his option exercise (tax-driven) and a director trimming small lot are routine 10b5-1 / vesting-liquidity events. No bearish read-through warranted. Continue to monitor for any C-suite cluster BUYS, which would carry strong informational content per the literature.

Executive Summary

CEO Gregory Smith sold $2.91M of stock and a director sold $271K on the same day, May 15. The CEO also exercised two sets of options (one cashless, one tax-costing). With $3.19M in total cluster sales against a $50.3B market cap (~0.006%), the dollar amount is trivial — under 0.01% of market value and well below the 0.1% materiality floor for insider clusters. These are routine liquidity/diversification sales, not a material bearish signal.
