Quick Scoop

ASM LT stage 4 usually means the final and strictest stage of Long-Term Additional Surveillance Measure in the stock market. It is used by exchanges to add heavy trading restrictions on a stock they consider risky or unusually volatile.

What it means

  • 100% margin on all clients : traders must fully fund the trade.
  • Settlement on a gross basis : trades are settled individually rather than netted off.
  • 5% price band : the stock’s daily price movement is tightly limited.

Why a stock reaches it

A stock can be placed in ASM when the exchange sees signs like unusual price moves, low liquidity, or other surveillance triggers; the goal is to protect investors and improve market integrity.
