The rupee was trading in a narrow range against the American currency in early trade on Tuesday and appreciated 4 paise to 83.48 against the US dollar amid a positive trend in domestic equities. Forex traders said the strength of the American currency in the overseas market, elevated crude oil prices and foreign fund outflows weighed on the local unit and restricted the up move. At the interbank foreign exchange market, the local unit opened at 83.48 against the greenback, registering a rise of 4 paise from its previous close. On Monday, the rupee settled 7 paise lower at 83.52 against the US dollar.

Moreover, substantial foreign direct investment (FDI) inflows are anticipated. The Adani Group is eyeing a USD 600 million rai
