- Each value is checked against Quanterix Corp's share prices from within about three months of its report date (insiders' Form 4 trades and the latest close).
- Value not shown for 1 row: the filed value is about 1,000 times too small for the share count at Quanterix Corp's share price.
- 1 row left out: the value per share it reports is far from Quanterix Corp's share prices on file from around the report date, far from the value most filers reported for that date, or the value of a security already left out, so it may describe another security or share class.
120 filers have only one report here.
Unusually large insider trades
Each trade is compared with the other insider trades of the same kind in the same security among Quanterix Corp's recent filings on file. Size alone is context, not a prediction or evidence of improper trading.
