Impact Assessment
High Impact on Trading: The enhanced margin requirements significantly impact liquidity and trading in affected securities. Stage I securities require minimum 50% margin, while Stage II requires 100% margin, substantially increasing capital requirements for traders. COOLCAPS traders face doubled margin requirements moving to Stage II. VIVIMEDLAB traders benefit from reduced requirements moving to Stage I. This surveillance action indicates heightened volatility or price movement concerns in these securities, potentially deterring speculative trading and encouraging more cautious market participation.
