You can still file a late claim in the $7.6M HighCape Capital ($QSI and $CAPA) settlement. The settlement claims that HighCape Capital misled investors about Quantum-Si’s product development, commercialization prospects, and financial outlook in connection with its SPAC merger. Investors who held shares in 2021 may still be eligible to file a claim: https://11th.com/cases/highcapecapital-investor-settlement

$QSI Swing traders and scalpers have taken over. I blame the company. Without a steady cadence of news, actual investors are being thrown to the wolves. Management, are you telling us you're spending $25 million a quarter and can't come up with anything positive to say once a month or so?

$QSI watch 30 yr interest rates. They fell 2 days ago, but recovered somewaht yesterday. If they go higher QSI will be quickly be down to .70 level..if they go even higher than 5.35,% then .52-.65 not unreasonable.If rates retreat back below 5%, then 1.20-1.70 not unreasonable (but not my call for lower rates)

[FAQ] Everything you need to know about the $7.6M HighCape Capital ($CAPA.DL0826 / $QSI ) Settlement Payout Q: What happened? A: HighCape Capital was accused of misleading investors about Quantum-Si’s readiness for commercial launch, growth prospects, and financial projections around its SPAC merger. As the company missed key commercialization targets, $QSI fell more than 70%, and investors filed a lawsuit. Q: Am I actually eligible? A: If you bought $CAPA.DL0826 / $QSI shares between 2021 and 2021, you’re likely eligible. You don’t need to hold the stock still to claim; past losses count Q: When do payouts happen? A: Typically, within 4–9 months after the claim deadline. But the exact timing depends on the court and settlement administration. Q: I missed the deadline. Is it too late? A: No, you may still be able to file a late claim, but acceptance depends on final approval by the court. Check if you're eligible and file a claim: https://11th.com/cases/highcapecapital-investor-settlement
