Indian stock markets have remained relatively stable compared to global counterparts, primarily due to the absence of a meaningful cohort of AI-focused stocks. According to reports from The Hindu BusinessLine, this has spared Indian investors the extreme volatility witnessed in markets where AI has become the dominant investment theme. The contrast is particularly stark with South Korea's benchmark Kospi index, which is highly concentrated with semiconductor giants Samsung Electronics and SK Hynix together accounting for over half of its total market capitalisation.
South Korea's Finance Minister was forced to apologise after single-stock leveraged ETFs caused significant losses for retail traders. As reported by The Hindu BusinessLine, Korean investors had piled into leveraged products such as single-stock 2x ETFs, fearing they would miss out on the AI rally. When share prices of these companies fell, these funds were forced to sell to rebalance, which deepened the decline and left substantial losses in investor pockets. The regulator subsequently introduced measures including curbs on retail exposure to high-risk products.
The Securities and Exchange Board of India (SEBI) has implemented comprehensive reforms to safeguard market integrity. According to The Hindu BusinessLine, after studies conducted during 2023-25 showed that over 91 per cent of individual investors were losing money in the derivatives market, SEBI responded with regulatory reforms including raising minimum contract values for single-stock F&O, increasing margin requirements for index derivatives, and tightening market-wide position limit norms.
SEBI has introduced new eligibility frameworks for derivatives on non-benchmark indices, requiring at least 14 constituent stocks with the largest stock's weight capped at 20 per cent and the top three together not exceeding 45 per cent. As reported by The Hindu BusinessLine, this follows the Jane Street episode where the firm made profits exceeding ₹36,500 crore ($4.3 billion) through index options and derivatives trading. The regulator has also tightened rules on index weights and introduced a closing call auction mechanism for F&O stocks from August 3 to improve price discovery at market close.
While SEBI's measures have reduced systemic risks from excessive leverage, retail investors must maintain realistic expectations and resist excessive leverage temptation. According to The Hindu BusinessLine, investors should evaluate portfolio performance under adverse scenarios including global risk-off environments and AI-driven capital spending slowdowns. The regulator's focus on reducing concentration risk and promoting greater diversification in the derivatives market aims to prevent manipulation risks, particularly relevant for indices like Bank Nifty where major banks account for over half of the index weight.
