Key Market Data

All figures above are as of 27 October 2026, sourced from Univest market data for the BSE listing. Only fields present in the source for this session are shown.

Price Action and Trading Activity

A gap opening defined the day. The stock opened at Rs 151.8 on BSE, a few paise under the ceiling, and its low for the day was that same Rs 151.8. The high and band limit was Rs 151.85, against a previous close of Rs 144.65.

The gain was Rs 7.2, equal to the 4.98% move in rupee terms. All numbers come from BSE alone, since band levels and previous-close values may differ on another exchange.

The whole session therefore sat inside a range of Rs 151.8 to Rs 151.85.

Why Standard Surfactants Ltd. Hit Upper Circuit

Buyers took the price straight to the exchange band, which is what an upper circuit is. No official company announcement or verified external catalyst had been confirmed at the time of writing, so the move is best read through price action and market sentiment.

As no trigger was confirmed, the article does not tie the rise to earnings, a corporate action, sector news or market rumours. If a confirmed announcement comes later, it would be added as a separate update.

The level reached was Rs 151.85.

What the Standard Surfactants Upper Circuit Means

A band caps how far a price may travel in one session, measured from the previous close. Here the stock reached that cap almost at once, so the ceiling of Rs 151.85 on 27 October 2026 set the entire range for Standard Surfactants Ltd.

Bands exist to slow sharp swings and keep trading orderly. They describe how the market is built, not what returns may follow. The circuit only marks where the price was held.

Standard Surfactants Ltd. Fundamentals and Valuation

The reported data for Standard Surfactants Ltd. show a PE ratio of 13.03, a PB ratio of 3.07, book value of Rs 47.16 and EPS of 11.1, against a market cap of Rs 119.5 crore. They are reference indicators and not a buy, sell or hold view.

A PB ratio of 3.07 means the market priced the company above its reported book value per share. Growth hopes, asset quality or thin trading in a smaller counter could each explain a premium of that kind.

A big one-day move gets noticed, yet valuation and returns on capital are separate questions that call for their own review. The numbers above are the latest reported ones.

Peer and Sector Context

Standard Surfactants Ltd. belongs to the Detergents & Soaps industry within the FMCG sector. The peer table below uses available companies from the same sector or industry to give broader valuation context.

Several of these peers are far larger by market capitalisation than Standard Surfactants Ltd. Size differences change liquidity and cost of capital, so the table is sector context rather than a like-for-like ranking.

Standard Surfactants Ltd.’s PE ratio was 13.03, compared with an available peer PE average of 28.53, calculated from the 1 peer companies that had a PE on record. This comparison is a valuation reference point, not a recommendation.

Technical Snapshot

The technical snapshot adds context: RSI was 38.46, the 50-day moving average was 166.02 and the 200-day moving average was 81.81.

Worth flagging: the RSI reading sits on the opposite side of neutral to the day move and the last traded price and the 50-day average point in different directions. Indicator values in the dataset can lag the live session, so they should be checked against a live chart before being relied on.

What Readers Should Know

The confirmed facts are few: Standard Surfactants Ltd. touched the upper circuit on BSE at Rs 151.85 on 27 October 2026, a 4.98% move on the day.

Execution is the main hurdle. Bids queue at the band while sellers stay away, so the quoted price may not be one at which shares can really be bought. No official catalyst had been confirmed when this was written either.

This is a market update and not a conclusion about the business. Strong interest at the band still leaves fundamentals, valuation, liquidity, risk and company disclosures to be checked.
