Impact Assessment
Traders and investors holding positions in ARFIN, BALCO, DANGEE, DELPHIFX, KAKATCEM, and OILCOUNTUB will face a significant increase in margin requirements to 100%, effectively doubling or more the capital required to maintain positions. This typically leads to forced liquidation by margin-constrained participants and reduced liquidity in these counters. OILCOUNTUB faces an elevated impact as it transitions from the less restrictive Short Term ASM to the more stringent Long Term ASM framework. No securities were moved to Stage IV (Trade-for-Trade), limiting the most severe trading restrictions to the Stage I category for this cycle.
Impact Justification
100% margin requirement imposed on 6 securities effective April 24, 2026, directly restricting trading activity and increasing cost of positions for market participants holding or intending to trade these stocks.
