Consistent investments by domestic institutions propelled the key Indian equity indices -- the Sensex and the Nifty50 -- to close the week's trade at record high levels, continuing their winning streak for the sixth consecutive week.
Despite some volatility, the benchmark indices moved higher riding on optimism surrounding the ongoing earnings season, market observers said.
On a weekly basis, the barometer 30-scrip Sensitive Index (Sensex) surged by 438.54 points or 1.28 per cent to close Friday's trade at a fresh level of 34,592.39 points.
The wider Nifty50 of the National Stock Exchange (NSE) crossed the 10,600-points-level for the first time this week.
The Nifty50 closed trade at a fresh high of 10,681.25 points, up 122.4 points or 1.16 per cent from its previous week's close.
The indices also touched their new 52-week highs. On Friday, the Sensex scaled a fresh intra-day high of 34,638.42 points and the Nifty50 of 10,690.25 points.
"With the constant inflow of funds in the domestic market, markets moved higher on optimism surrounding corporate earnings amid mixed global cues," D. K. Aggarwal, Chairman and Managing Director of SMC Investments and Advisors, told IANS.
During the week, two global software majors -- Tata Consultancy Services (TCS) and Infosys -- came out with their earnings for the third quarter of 2017-18.
While TCS reported 4 per cent annual decline in consolidated net profit to Rs 6,545 crore for the period under review, Infosys' net profit was reported at a record 38 per cent annually in rupee terms.
"Continuous buying by domestic institutional investors (DIIs) and expectation of recovery in this earnings season led to the rise in indices. Domestic institutions bought shares worth Rs 1,446 crore in the past 10 sessions," Arpit Jain, AVP at Arihant Capital Markets, told IANS.
Provisional figures from the stock exchanges showed that DIIs purchased stocks worth Rs 2,383.11 crore during the week, while foreign institutional investors (FIIs) sold scrips worth Rs 965.16 crore.
Figures from the National Securities Depository (NSDL) revealed that foreign portfolio investors bought equities worth Rs 554.03 crore, or $88.34 million, during January 8-12.
Vinod Nair, Head of Research, Geojit Financial Services, said: "Liquidity from FIIs and DIIs continues to support domestic market sentiments. On the global front, strong global metal prices and rising crude prices continue attract positive investor sentiments."
"Further, US investors remained optimistic on strong economic growth outlook led by better than expected quarterly earnings," Nair added.
On the currency front, the rupee weakened by 26 paise to close at 63.63 against the US dollar from its last week's close at 63.37.
In another economic development, the Union Cabinet this week opened up Air India for foreign investors and brought in changes in key sectors by allowing 100 per cent foreign investment in single brand retail and construction development through the automatic route.
"Besides spurring growth in the economy, this step is likely to contribute to growth of investment, income and employment," Aggarwal said.
"Sectorally, the top gainers were the realty, IT, media and metal indices. The top losers were the PSU bank, infra and auto indices," Deepak Jasani, Head - Retail Research, HDFC Securities, told IANS.
