New Delhi: Bombay Stock Exchange (BSE) has imposed a new weekly trading surveillance measure on nine stocks, including RRP Semiconductors, to address excessive volatility following unusual price movements in the stocks. 

The exchange announced that starting November 10, 2025, new measures will apply to companies exclusively listed on BSE under specific groups, that trade above Rs 100, have a 2 per cent price band, and possess a price/earnings (PE) ratio greater than 500 or negative, and that have reached the upper price band for two consecutive weeks.

“In continuation of our endeavour to maintain market integrity and curb excessive price movement in securities listed exclusively on the BSE trading platform, a need has been felt to further strengthen the extant surveillance measures,” the exchange said in a statement.

BSE included nine stocks in this measure including, Citizen Infoline, Colab Platforms, Dugar Housing Developments, EMA India, Mardia Samyoung Capillary Tubes Company, Omansh Enterprises, Oswal Overseas, RRP Defense and RRP Semiconductor.

Securities placed under this measure can only trade once a week, either on Monday or the first trading day of the week, within a 1 per cent price band. BSE announced that identification of stocks will occur weekly on Fridays or the last trading day of the week, with quarterly reviews for exiting the framework and with a minimum one-month retention.

BSE also said that the new framework will be in addition to all other prevailing surveillance measures being imposed by the exchanges from time to time. The exchange also clarified that “the shortlisting of securities under this framework is purely on account of market surveillance, and should not be construed as an adverse action against the concerned company.”

The shares were bought at Rs 127 per piece, which is 17 per cent above the issue price. This translates into a transaction size of Rs 136.17 crore.

In India, Think Investments has built a diverse portfolio with investments in some of the prominent companies, including Swiggy, FirstCry, Urban Company, PharmEasy, Experian, Spinny, NSE, Star Health, Meesho, Rapido, Chaayos, and Dream11.

PhysicsWallah is preparing to launch its Rs 3,480-crore initial public offering (IPO), opening on November 11. The firm has fixed a price band of Rs 103-109 per share, targeting a valuation of over Rs 31,500 crore at the upper end.

The IPO includes a fresh issue of Rs 3,100 crore and an offer-for-sale (OFS) of Rs 380 crore by co-founders and promoters Alakh Pandey and Prateek Maheshwari.

The issue will close on November 13, with anchor investor allocation scheduled for November 10.

The Nasdaq Composite ended slightly lower on Friday but posted its sharpest weekly loss since early April, as investors questioned how long the artificial intelligence boom could sustain recent market highs. The index slipped 0.21% to 23,004.54, bringing its total weekly fall to around 3%, while chipmakers and technology shares led the declines.Despite this pullback, the Nasdaq has surged more than 50% since April, when US President Donald Trump announced wide-ranging tariffs, with AI optimism lifting markets to record levels. However, sentiment cooled this week after Nvidia CEO Jensen Huang was quoted by The Financial Times as saying that China may surpass the US in the AI race. “We’re seeing this AI selloff continue after the comments we had about China winning the AI race,” said Michael O’Rourke, chief market strategist at JonesTrading in Stamford, Connecticut, as per news agency Reuters. He added that the sector’s weakness reflected “a recalibration of multiples” and some investors taking profits after a strong run.The S&P 500 rose 0.13% to 6,728.81, and the Dow Jones Industrial Average gained 0.16% to 46,987.10, both rebounding late in the session after reports suggested progress in ending the longest federal government shutdown in US history. The global equities index MSCI (.MIWD00000PUS) slipped 0.07%, and the STOXX 600 in Europe lost 0.55%, as weak trade data from China renewed worries over slowing global growth.Chinese exports fell 1.1% in October, the steepest decline since February, underscoring the damage from Trump’s tariffs and denting investor confidence across Asia.In the bond market, US treasury yields edged down after surveys pointed to worsening consumer sentiment. The University of Michigan’s preliminary index for November dropped to 50.3, the lowest since June 2022, driven by record-low views of current economic conditions amid concerns over the shutdown. The 10-year Treasury yield eased slightly to 4.091%.The US dollar weakened against major currencies, with the dollar index slipping 0.11% to 99.57. The euro firmed to $1.1563, while the yen weakened to 153.45 per dollar. As per Reuters, the shutdown has delayed key economic reports, though current indicators suggest the economy remains resilient, potentially reducing pressure for the Federal Reserve to cut rates at its December meeting.Meanwhile, oil prices rebounded on optimism after Trump met Hungary’s Prime Minister Viktor Orbán at the White House, fuelling hopes that Hungary could use Russian crude. US crude settled 32 cents higher at $59.75 per barrel, while Brent rose 25 cents to $63.63. Gold prices also firmed as investors sought safety amid uncertainty.
