$STRK is the worst ever, with a principal-protected financial product where the interest rate has been adjusted more than five times in 60 days, going from 29.9% annualized down to 8% annualized. It's poorly managed and relies on clever tricks, taking advantage of clients' anxiety about large losses when redeeming within the term to continually lower the interest rate! This is the first time I've seen such a poorly managed financial product. Although some fees were saved, it also reveals the small-mindedness and narrow vision of the project team, with a clear display of penny-pinching thinking! Anyway, there are still ten days until maturity, and after that, I will never touch this garbage again!
