Extending losses for a fifth straight session, the BSE benchmark Sensex plunged nearly 310 points to close at a three-week low of 34,757.16 and the NSE Nifty fell over 94 points to 10,667 on Monday, 5 February, dragged down by concerns over certain budget proposals and sell-offs in global markets.
Investors also seemed cautious ahead of the RBI policy meet as they feel that repo rate might be increased amid inflation concerns, brokers said.
The last week's budget proposal of 10 percent long-term capital gains (LTCG) tax on equities and overshooting of fiscal deficit target also quashed investor optimism.
However, the government on 5 February tried to downplay the impact of budgetary proposals on domestic equities and attributed the current downtrend to global market cues.
The 30-share Sensex stayed in the negative zone through the session and hit a low of 34,520.80 before recovering partially to settle lower by 309.59 points, or 0.88 percent, at 34,757.16, a level last seen on 12 January when it had closed at 34,592.39.
The barometer had lost 1,216.50 points in the previous four sessions, following nervous offloading of positions by participants, triggered by imposition of long-term capital gains of 10 percent on equities in the Budget 2018.
Also, the 50-share NSE Nifty settled lower by 94.05 points, or 0.87 percent, at 10,666.55 after shuttling between 10,586.80 and 10,702.75.
Globally, other Asian markets too ended lower and European shares were in the negative zone in their early session following deep losses on Wall Street last week after a strong US jobs report and rising Treasury yields fanned fears of interest rate hike quicker than thought.
Foreign portfolio investors, however, remained buyers on the Indian bourses as they bought shares worth Rs 950 crore on Friday. But domestic institutional investors (DIIs) sold equities worth Rs 508.78 crore, according to provisional data from the exchanges.
Brent oil hovering around USD 70 a barrel in global market too had its shadow on the sentiments.
