Tenax Therapeutics, Inc. scored higher than 29% of companies evaluated by InsiderBuying, and ranked 51st out of 99 stocks in the biotech sector.

Scores are percentile-ranked against every company we scored that day, with extra weight given to the size and conviction of each purchase and the seniority of the buyer.

Dollars Committed

Insiders at Tenax Therapeutics, Inc. bought $132.8K of stock across 4 purchases in the last 90 days, the largest of them $101.8K.

Stake Increase

The average purchase added about 60% to the buyer's existing holding. Doubling a stake earns full marks here; topping up an already large position earns very little.

This category carries 35% of the Insider Score.
