Over the past year there were no insider purchases at Proto Labs Inc. Three insiders sold roughly $3.5 million instead.
That's worth context: executives sell for plenty of routine reasons, from scheduled trading plans to tax bills. Buying is the rarer, more telling signal.
Big money check: 277 institutions held PRLB as of Q2 2026, and more funds bought than sold. Looking at the quarterly pattern: 4 quarters in a row of net selling by insiders. Insiders bought in 1 of the last 7 full quarters.
