Six stocks, including Indiabulls Housing Finance, Indian Energy Exchange, The India Cements, Bharat Heavy Electricals, Manappuram Finance, and Delta Corp, were put under the F&O ban on Wednesday. Their contracts enter the ban zone when the open interest reaches 95% of the market-wide positions limit. Although banned for F&O trade, the shares will be available for trading in the cash market. Traders in indices aren’t affected by security bans. Indian equities started positively on Tuesday with Nifty hovering near the upper band of consolidation, awaiting a positive trigger for a breakout.
