Shares of BSE dropped around 3% on Tuesday, extending losses for the fifth consecutive session after Nuvama downgraded the stock’s rating to Hold from Buy, and slashed its target price, listing three key headwinds converging in FY27.

BSE shares dropped to Rs 3,235 apiece on Tuesday morning, the lowest level seen by the stock in around five months. Shares of the stock have now fallen more than 10% over five consecutive sessions of losses.

Nuvama on BSE share price

Nuvama downgraded its rating on the shares of BSE to ‘Hold’ and slashed its target price to Rs 3,240 apiece from Rs 4,090 apiece. The latest target price implies around 3% downside potential from the stock’s previous closing price of Rs 3,332 apiece.

The brokerage highlighted three headwinds for the stock exchange that converge in the ongoing financial year 2027. Here are the 3 key headwinds.

1) CAS has reset volumes, impairing expiry-day decay trading dynamics

The newly introduced closing auction session (CAS) has led to huge confusion among traders, resulting in lower participation. Nuvama highlighted that BSE’s index option premium volumes (ADPTV) of Rs 18,100 crore are the lowest since January 2025.

The premium per contract, which had spiked 54% to Rs 2,605 in the first week of August, has fully unwound, and premium-to-notional is back to 11.1 bps versus 10.9 bps in July, it added, noting that the key issue is lower trading velocity and participation loss.
“Earlier, option premiums decayed predictably into expiry, enabling repeated participation through short duration trades. CAS introduces uncertainty in final settlement due to auction-based closing, reducing the predictability of this decay path. This weakens theta-harvesting strategies and reduces leverage for buyers that previously relied on rapidly falling premiums, and reduces seller interest due to uncertainty of option decay—impacting a large part of the ecosystem,” Nuvama said.The damage is visible as BSE expiry-day contracts fell 33% versus 24% for non-expiry, the brokerage highlighted.

2) Bank guarantee norms are second leg

RBI’s bank guarantee norms are the second leg, and they arrive precisely as CAS impact could heal, according to Nuvama. Tighter collateral requirements may raise capital intensity for intermediaries, reducing turnover efficiency in high-frequency strategies that drive contract volumes, it added.

The brokerage feels that the impact is likely gradual but could cap recovery into FY28.

3) Market share gains are nearing saturation

Nuvama highlighted that BSE’s contract share of nearly 51.5% is already high, but ADPTV’s share remains lower at around 36%, due to a lower mix of non-expiry-day contribution. This is limiting incremental upside from further share gains, according to the brokerage.

“With contract MS at 50% and incremental levers exhausted, we see no near-term trigger. The gap to ADPTV share of 36.3% is structural due to higher concentration near expiry,” it further said.

Nuvama cut BSE’s EPS estimates by 6.3% for FY27 and 15% for FY28. However, it sees a recovery in VIX as the largest swing factor, suggesting that a move in VIX towards 16–18 could materially lift premium per contract and ADPTV even without a recovery in contracts.

Faster-than-expected adaptation to CAS, deeper closing-auction liquidity, regulatory recalibration of CAS mechanics, and stronger non-expiry participation could also drive volumes above Nuvama’s revised assumptions.

Jefferies on BSE share price

Nuvama’s downgrade comes a day after Jefferies downgraded the counter to ‘underperform’ from ‘hold’ and trimmed the target price to Rs 2,940 from Rs 3,520.

Jefferies flagged risks to BSE’s revenue from domestic proprietary traders, who account for around 50% of notional turnover. It sees headwinds from the STT hike, RBI’s bank guarantee norms and the Closing Auction Session (CAS).

BSE share price

BSE shares have fallen over 9% in a week and 8% in a month, although the stock is overall up 25% in 2026 so far. After hitting a 52-week low of Rs 2,021.50 apiece in September last year, BSE shares more than doubled in eight months to hit a 52-week high of Rs 4,447 apiece in May this year. The stock has now fallen more than 27% since then to trade at Rs 3,235 apiece on Tuesday morning.

In the longer term, BSE shares have delivered stellar returns of 1,038% in three years and more than 2,500% in five years. The company has a market capitalisation of more than Rs 1.3 lakh crore.

The number of job vacancies has fallen to its lowest level in more than five years as smaller businesses cut back on recruitment, the latest official figures indicate.

Vacancy numbers dipped slightly over the May-to-July period to 707,000, according to the Office for National Statistics (ONS), which said small firms were citing labour and operating costs as reasons for scaling back hiring.

The ONS said the labour market was “little changed overall”, with the unemployment rate remaining at 4.9%.

Growth in regular earnings – which excludes bonuses – picked up slightly, rising at an annual pace of 3.5% in the three months to June.

Labour councillor Rosy Moore, from Cambridge City Council, which is the lead authority, said: “We’ve been so successful that all of our [grant] money is booked to be spent, as it were, that’s all in the pipeline.

“So we’ve actually written to the department and asked if they could extend it for us because our partnership is working so well.”

Brain said he learned of the scheme through a representative at the door.

“We were very sceptical, but we went online and we checked them out, and then we checked whether it was a legitimate thing through the government website,” he said.

“We registered, and then we got a call from a contractor that had been appointed, they came and did a survey, and we were still very, very sceptical, but we worked through the process.

“They answered the questions. There was no hard sell or a hard push, and because they’d satisfied my scepticism, we went ahead.”

Asked if he thought it was too good to be true and a scam, Brain said: “All the way through, to be honest with you… it was only at the end, once the process had been done and they’d sent me the handover package, that I thought, ‘Well, you know, it does seem too good to be true, but you know, we were a beneficiary from it, thankfully.’”
