The rupee showed a recovery from its lower level and gained marginally by 1 paisa to 84.06 against the US dollar in early trade on Monday, tracking positive cues from domestic equity markets and a soft American currency. However, sustained outflow of foreign funds and an upward momentum in the crude oil prices weighed on the local unit, forex traders said. At the interbank foreign exchange, the rupee opened at 84.06 against the greenback and stayed almost flat in early deals, trading 1 paisa higher from its previous close. On Friday, the rupee slipped 1 paisa to close at 84.07 against the US dollar.
