India’s stock market extended its rebound on Friday, December 12, 2025, with metals and select large-caps powering the upside even as investors stayed cautious ahead of key macro data and a sharply weaker rupee. By mid-morning, the Nifty 50 hovered around 26,000 and the Sensex around 85,000+, supported by broad-based buying across most sectors. 1
Below is a curated round-up of the biggest gainers on Indian equities today, the news triggers behind the move, and what brokerages/strategists are watching next—based strictly on reporting and market updates dated 12.12.2025.
Market mood today: rebound continues, but eyes on inflation + rupee
The rally followed positive global cues after the U.S. Federal Reserve’s rate move, but traders also stayed alert to India’s November inflation print expected later in the day. Reuters noted that while global cues helped sentiment, foreign outflows and currency weakness continued to cap risk appetite. 1
On the currency front, Indian media trackers flagged the rupee sliding to fresh lifetime lows in early trade—an important cross-current because it can change the outlook for import-heavy sectors and rate expectations. 2
Biggest stock gainers today: top movers on BSE (as of ~12:40 pm IST)
These were the largest percentage gainers on the BSE “Top Gainers” screen around midday (lists are dynamic and can change rapidly with price moves). 3

Top gainers among large-caps today: Nifty/Sensex movers
While broader-market lists throw up midcaps/smallcaps, the headline leadership came from metals + select defensives/cyclicals.
Large-cap gainers (midday snapshot):
- Tata Steel: ~+2.5%
- Hindalco: ~+2.4%
- Larsen & Toubro (L&T) : ~ +1.8%
- UltraTech Cement: ~+1.7%

Why metal stocks led today: copper + silver strength and “all green” sector breadth
If Friday had a single leadership theme, it was metals.
One market update noted that the Nifty Metal index was higher intraday with all constituents in the green, with strong moves in Hindustan Copper, Hindustan Zinc, NALCO and Hindalco. The same report linked momentum to record/strong commodity pricing, including copper strength and silver’s sharp rally (benefiting silver-levered names). 6
A separate Business Standard report highlighted Hindustan Copper and Hindustan Zinc climbing to/near fresh highs, while GMDC and NALCO also advanced—framing the move in the context of improved demand expectations and supportive commodity trends. 7
What it means for “top gainers” lists: when the underlying commodity complex is bid, metal stocks tend to dominate percentage-gainer screens across both large-caps and broader market.
Stock-by-stock: today’s biggest gainers and the key news triggers
1) Anant Raj: biggest gainer on BSE screens
Anant Raj topped gainers lists around midday, rising roughly 8–9% in intraday trade. 3
Business Standard’s “A-group” movers list also flagged Anant Raj as the top gainer, alongside other strong performers like Share India Securities, Transformers & Rectifiers India, GMDC, and Hindustan Copper. 8
2) Hindustan Copper + Hindustan Zinc: momentum + commodity tailwinds
Business Standard reported Hindustan Copper rallying sharply intraday and Hindustan Zinc extending a multi-session run, with commentary tying strength to the broader metals upcycle and supportive pricing dynamics. Business Standard
Upstox’s sector note also pointed to copper strength and silver’s rally as notable tailwinds for the pack. 6
3) Tata Steel: brokerages split, but expansion roadmap keeps it in focus
Tata Steel’s rise came amid active debate on its growth blueprint and integration moves. A brokerage round-up described diverging views—from bullish takes highlighting feedstock security and longer-term growth options to more measured stances watching steel prices and capex execution. Business Standard
The metals-sector note also referenced board-level moves and strategy for the India business, keeping Tata Steel on traders’ radar during the metal-led session. 6
4) L&T: Goldman Sachs upgrade lights the fuse
One of the cleanest news-to-price stories today was L&T, which climbed after Goldman Sachs upgraded the stock to “Buy” and raised its target price (reported as a Street-high target in market coverage). Reuters+1
The rationale cited in coverage centered on growth visibility, backlog strength, and new opportunities (including newer verticals) supporting a re-rating narrative. 9
5) Thermax: brokerage upgrade sparks a sharp move
Reuters also pointed to Thermax jumping after a brokerage upgrade, as investors hunted for valuation and order-flow driven stories beyond mega-caps. Reuters
A Reuters-linked brief further described the upgrade as being tied to order inflows and a constructive growth outlook in newer markets. 10
6) Vedanta: critical minerals win adds a fresh catalyst
Vedanta moved higher after it was reported as the successful bidder for the Genjana nickel, chromium and PGE block in the government’s critical minerals auction tranche—an announcement framed as strengthening its critical minerals portfolio. 11
7) IDBI Bank: stake sale chatter drives buying interest
IDBI Bank gained after reports indicated Fairfax Financial and Kotak Mahindra Bank were emerging as key contenders in the process to buy a controlling stake, with financial bids expected by end-December. 12
8) Kaynes Technology: sharp rebound from recent lows
Kaynes Technology featured on the top-gainers list amid a rebound that was widely described as value buying after a steep slide, alongside references to brokerage commentary and targets in market coverage. 13
What analysts are saying: near-term watchpoints for the rally
Even with markets green, commentary on the day emphasized three immediate variables:
- Inflation data risk: Investors stayed positioned for a modest rise in November inflation after an unusually low October reading, per Reuters market coverage. 1
- Rupee weakness + flows: Currency pressure and persistent foreign selling were cited as sentiment brakes, even as the Fed-linked global tailwind helped. 1
- Rotation into cyclicals: Today’s leaderboard shows rotation into metals, infra, and select industrial themes, consistent with a “risk-on but selective” tape. 6
Forecasts and outlook (published around 12.12.2025): 2026 targets back in focus
Today’s gainer list is very “now,” but investor attention is already shifting to 2026 roadmaps.
- Jefferies said Indian equities could do better in 2026, citing a potential earnings rebound and steady domestic flows, and published a Nifty target of 28,300 for end-2026 in its outlook. 14
- Another widely carried strategy view pegged Nifty at 29,000 by end-2026, pointing to themes like demand revival, liquidity support, and the possibility of an India–U.S. trade deal becoming less of a headwind. 15
These forecasts don’t explain every intraday spike, but they do shape the sector narratives that often dominate Discover/News interest—especially around cyclicals, domestic-demand plays, and policy-sensitive themes.
How to read today’s “top gainers” list without getting trapped by noise
Top-gainer screens are useful—but they can also be misleading. Here’s what professional readers typically check:
- Catalyst clarity: Is the move tied to a concrete trigger (upgrade, order win, auction result), or purely momentum?
- Liquidity + circuit risk: Smaller names can jump quickly; exits can be harder if sentiment flips.
- Sector correlation: When a whole sector is green (like metals today), leaders often rise simply because sector flows are strong—not because of single-stock news. 6
- Event calendar: Macro prints (inflation), central-bank cues, and currency moves can reverse a rally fast. 1
Bottom line
India’s biggest stock gainers today (12.12.2025) were led by Anant Raj and a cluster of metal-linked names such as Hindustan Copper, Hindustan Zinc, GMDC and NALCO, while large-cap momentum came from Tata Steel, Hindalco and JSW Steel on the commodity tailwind, and L&T on a high-profile brokerage upgrade. 3
With inflation data due and the rupee under pressure, traders may continue to favor news-backed gainers and sector leaders rather than chasing every percentage spike. 1
