The rupee opened on a flat note and rose 5 paise to 75.60 against the US dollar in early trade on Monday as weak greenback restricted the losses stemming from concerns over rising COVID-19 cases. Forex traders said weak domestic equities, foreign fund outflows and rising COVID-19 cases weighed on investor sentiments. However, weak American dollar supported the local unit and restricted the decline. The rupee opened on a flat note at the interbank forex market at 75.64 against the US dollar, then gained some ground and touched 75.60 against the US dollar, up 5 paise over its last close. It had settled at 75.65 against the US dollar on Friday.
