New Delhi: The Union Budget 2017-18 provided the feel-good factor as the Sensex today leaped close to 486 points to close at an over 3-month high of 28,142, with financial and realty stocks powering the momentum.

Markets welcomed the budgetary proposals of infusing Rs 10,000 crore in public sector banks and keeping long-term capital gains tax (LTCG) and short-term tax rate (STCG) unchanged for the capital market.

Additionally, Finance Minister Arun Jaitley proposed that category I and II foreign portfolio investors (FPIs) should be exempted from taxation on indirect transfers, which made investors a happy lot.

Both key indices Sensex and Nifty reclaimed their key levels of 28,000 and 8,700 for the first time, scoring their biggest single-day gain since October 2016. The Sensex, which kept moving in a tight range immediately after the Budget was presented in Parliament, started climbing and closed higher by 485.68 points, or 1.76 per cent, at 28,141.64.

This is its highest closing since October 24 last year when it settled at 28,179.08. It had shot up about 504 points intra-day. The broad-based Nifty was also on the upswing and rallied by 155.10 points, or 1.81 per cent, to settle at 8,716.40 after touching the day's high of 8,722.40 and a low of 8,537.50.

The rupee appreciating 34 paise to 67.53 (intra-day) against the dollar added to the positivity. Sentiment was boosted after Jaitley cleared the air on the fiscal deficit road map.

Meanwhile, Nikkei Markit India Manufacturing PMI in January rebounded from the demonetization downturn amid rising order books, production as well as buying levels and expansion in the sector by increasing to 50.4, from 49.6 in December.

Shares of state-run banks such as SBI, Union Bank of India, Bank of Baroda, PNB and Syndicate Bank hogged limelight and climbed by up to 5.64 per cent as the government announced infusion of Rs 10,000 crore in public sector banks in the next fiscal.

The Budget also allocated a record Rs 3.96 lakh crore to the infrastructure sector. Also, the government announced infrastructure status to affordable housing to encourage investment and offered tax sops for developers sitting on completed unsold inventories, which triggered buying in realty stocks.

DLF, Godrej Properties, HDIL, Oberoi Realty, Prestige Estate Projects, Sobha Ltd and Unitech zoomed by up to 6.74 per cent. Shares of companies related to the agriculture sector such as Dhanuka Agritech and Jain Irrigation Systems ended higher by up to 3.71 per cent after Jaitley announced a whopping Rs 1 lakh crore hike in credit target for the next fiscal to Rs 10 lakh crore as part of efforts to double farm income in the next five years.

Major gainers included Maruti Suzuki (4.69 per cent), M&M (4.64 per cent), ITC (4.51 per cent), ICICI Bank (4.40 per cent), GAIL (3.76 per cent) and Adani Ports (3.60 per cent).
