AMERIPRISE FINANCIAL INC Significantly Reduces Stake in Quanteri

AMERIPRISE FINANCIAL INC has significantly reduced its stake in Quanterix Corp (QTRX) by 80.18%, selling 4,005,849 shares at $3.13 each. This move leaves the investment firm with 990,224 shares of Quanterix, representing 2.10% of its portfolio. The transaction reflects a strategic reallocation by AMERIPRISE FINANCIAL, possibly due to Quanterix's underperformance, as the stock has since declined by 8.15% and has a low GF Score of 67/100, indicating poor future performance and potential as a value trap despite being significantly undervalued.
