Where TMDX holders stand

StockMarketLoop's Market Position model estimates how the shares traded between 2026-08-12 and 2026-11-10 were bought. Its estimate of the average cost basis is $78.49; at $93.57 the stock trades 19.2% above that level. About 96.2% of those shares are estimated to be held at a profit at the current price. A high figure means most recent buyers are in the green, which can mean fewer trapped holders overhead, and also more people with gains who might sell. The densest nearby clusters of cost basis sit around $70.40 (support) and $93.45 (resistance). Roughly 70% of the estimated cost basis lies between $69.03 and $88.23, and 90% between $66.84 and $92.62.

This is a model estimate built from price and volume history, not a record of actual positions.
