StockMarketLoop's Market Position model estimates how the shares traded between 2026-07-17 and 2026-10-15 were bought. Its estimate of the average cost basis is $8.22; at $6.25 the stock trades 24.0% below that level. About 0.0% of those shares are estimated to be held at a profit at the current price. A low figure means most recent buyers are underwater, so rallies can meet selling from holders trying to get back to break even. Roughly 70% of the estimated cost basis lies between $7.45 and $9.01, and 90% between $6.70 and $9.24.
This is a model estimate built from price and volume history, not a record of actual positions.
