ASM vs. GSM (Graded Surveillance Measure)

ASM tends to focus on stocks that exhibit unusual price changes or trading activity. On the other hand, GSM targets companies that aren’t performing well financially, using a tiered system of tightening limits.

ASM vs. F&O Ban

ASM focuses on specific stocks that are selling or changing in unusual ways. When an F&O ban is implemented, trading in futures and options on a stock is suspended. This stops derivatives, but trading on the cash market remains.
