Indian equity benchmarks head into Wednesday’s session on the back foot after the Nifty 50 booked its sixth straight losing session on Tuesday, August 18, as Brent crude held above $90 a barrel and global bond yields climbed to multi-year highs. Early signals for August 19 aren’t encouraging either: GIFT Nifty futures were quoted 15 points lower at 24,208, and South Korea’s Kospi tumbled 7% in a semiconductor-led selloff across Asia, per Business Standard. Here’s what’s moving stocks today.
Key Takeaways
- Nifty 50 closed at 24,154.90 (-0.55%), its sixth straight losing session, as Brent crude held above $90/bbl on Strait of Hormuz supply risk
- GIFT Nifty signals a tepid August 19 open, down 15 points at 24,208, as Asia’s Kospi slides 7% on a chip-stock selloff
- Aster DM Quality Care in focus after a TPG-backed ₹4,780-crore block deal — even as Q1 net profit fell 81% YoY
- Paytm parent One97 Communications saw a ₹2,949-crore block deal; the economic proceeds go to Antfin, not founder Vijay Shekhar Sharma
- RailTel, Groww, Krystal Integrated, Exide, Atlanta Electricals and Jubilant Ingrevia are among names with fresh order wins or stake-sale triggers
- Bandhan Bank, LIC, Manappuram Finance and SAIL remain in the F&O ban list for Wednesday
What Could Push Nifty Into a Seventh Straight Losing Session
Four triggers are worth tracking through today’s session:
- Brent crude touched its highest level since July 30 on Monday and added a further 0.5% to $91.3 a barrel on Tuesday, after the US-Iran ceasefire officially lapsed on August 17.
- Shipping through the Strait of Hormuz has slowed sharply — just five commodity vessels transited the waterway on the most recent Saturday and none on Sunday, against 31 the previous weekend, per Trading Economics.
- President Trump has said Washington isn’t currently pursuing an extension of the interim US-Iran agreement and has signalled Americans should brace for somewhat higher gasoline prices as the standoff continues.
- The US Federal Reserve’s meeting minutes are due later Wednesday — a scheduled catalyst that could move global bond yields and, with them, the FII flows that have already turned choppy this week.
A close below 24,000 on the Nifty would confirm a fresh near-term low and open the door to a seventh consecutive session of losses.

Technically, the Nifty faces resistance at 24,240, with support seen in the 24,050-24,000 zone. On the flows front, FIIs were net buyers of ₹1,651.53 crore and DIIs net bought ₹2,579.31 crore in the cash segment on August 18, per Kotak Neo’s FII-DII data, a rare instance of both investor classes buying even as the index fell, pointing to crude-linked profit-booking concentrated in IT and auto counters rather than broad-based selling.

Bulk and Block Deals
Aster DM Quality Care is set to see up to 7.2% of its equity change hands after Centella Mauritius Holdings, a TPG-backed vehicle holding a 9.9% stake at the end of Q1, proposed a block deal worth roughly ₹4,780 crore at a floor price of ₹766.10 a share, a 6.3% discount to the prior close, with a 60-day lock-in on the residual stake.
The transaction lands alongside soft numbers: Aster DM Quality Care’s consolidated net profit fell 81.2% YoY to ₹16.1 crore for the quarter ended June 2026, down from ₹85.5 crore a year earlier.
One97 Communications, Paytm’s parent, saw roughly 1.92 crore shares (2.95% of equity) change hands at ₹1,535.10 apiece, a ₹2,949-crore block deal, as Resilient Asset Management BV proposed selling up to 4.98% of the company.
One clarification worth flagging here: while Resilient is owned by founder Vijay Shekhar Sharma, the economic proceeds are contractually routed to Antfin (Netherlands) Holding BV, the Alibaba-linked entity, under a 2023 Optionally Convertible Debenture agreement, per Business Standard and ANI.
Sharma’s own direct 9.03% stake is unaffected by the sale. It follows a strong quarter: Q1 FY27 consolidated profit rose 79% YoY to ₹220 crore on 28% revenue growth to ₹2,448 crore, with EBITDA margin expanding to 8% from 4% a year earlier.
Billionbrains Garage Ventures, Groww’s parent, is in focus after Y Combinator’s YC Holdings II LLC sold 1.19% of the company, 7.47 crore shares, for ₹1,435.19 crore at an average ₹192.16 a share, trimming its holding to 7.44% from 8.63%, per Business Standard. It’s YC’s second sale this year after offloading 1.45% in May, taking its 2026 proceeds from Groww past ₹3,077 crore.
The sale follows a strong Q1 FY27, in which net profit rose 94% YoY to ₹735 crore on 66% revenue growth to ₹1,501 crore.
Bottom Line
Wednesday’s session will likely stay hostage to crude and global bond yields rather than domestic earnings, with GIFT Nifty and a 7% Kospi slide both pointing to a cautious start.
Within stocks, watch for follow-through in block-deal names, Aster DM Quality Care and One97 Communications, where fresh floor prices could act as near-term support or resistance, and for order-book updates from RailTel, Krystal Integrated and HG Infra as the Q1 FY27 earnings season enters its final stretch.
