<h1>High intraday volatility and concentrated trading prompt scrutiny of disclosure, surveillance, and insider trading compliance obligations for market participants</h1> Benchmark equity indices closed effectively flat after a volatile session, with sectoral gains offset by losses and significant intraday swings, while institutional flows showed net foreign selling and strong domestic buying; these facts raise legal considerations for market regulators and listed companies including obligations on continuous disclosure, surveillance for market manipulation or insider trading given large intraday volatility and concentrated sector moves, and potential scrutiny of trading by major institutional participants. Market participants must ensure compliance with securities laws, reporting requirements and risk-disclosure obligations to investors.
