The Securities and Exchange Board of India (SEBI) has recently proposed the removal of weekly expiry contracts from Indian stock market derivatives. While the intention behind this move is to streamline the market and improve its efficiency, it raises several concerns for traders, investors, and institutional participants. In this blog, we will explore the potential pitfalls of such a policy change, and how it could impact different stakeholders in the Indian financial ecosystem.
What is the Weekly Expiry in the Stock Market?
In the derivatives market, particularly for options and futures, an “expiry” is the date on which the contract ceases to exist. Currently, in India, the National Stock Exchange (NSE) offers weekly expiry contracts for various stock indices and individual stocks. This means options and futures on these stocks and indices have an expiry every Thursday, providing traders with more flexibility to trade and hedge their positions more frequently.
SEBI’s Proposal: What’s the Plan?
SEBI’s recent consultation paper proposes removing weekly expiry contracts in favor of keeping the traditional monthly expiry cycle. The move is being framed as a way to bring more stability and reduce market volatility caused by high-frequency trading and excessive speculation.
While the move aims to simplify the trading process, it could have several unintended consequences for a wide range of market participants, including traders, investors, and institutions.
1. Impact on Retail Traders:
Retail traders are among the most affected by the potential removal of weekly expiry contracts. Here’s why:
Reduced Flexibility in Trading
Weekly expiries offer traders the ability to capitalize on short-term market movements, enabling quick adjustments to their positions. Without weekly expiries, traders will have to wait for the next monthly expiry, making it harder to hedge or take advantage of smaller price fluctuations in between. For active retail traders, this means fewer opportunities for quick profits.
More Exposure to Risk
With fewer expiry dates, traders will be exposed to larger swings in stock prices due to the lack of timely options to offset their positions. Weekly expiries allow traders to manage risk more effectively and limit losses within a week. Without them, there’s a higher chance of running into significant losses during the longer wait for the monthly expiry.
Impact on Strategies
Popular options trading strategies like “iron condors” and “strangles” rely on weekly expiries to maximize profits from time decay. The removal of weekly expiries will limit the flexibility of these strategies, forcing retail traders to adapt to a more restricted timeframe.
2. Effect on Investors:
Investors, who typically take a longer-term view of the market, may also feel the ripple effects of the proposed change.
Impact on Hedging Options
Institutional investors and HNI (High Net-Worth Individuals) investors use derivatives to hedge their portfolios. Weekly expiries give investors the option to hedge their portfolios with greater frequency. The removal of this option could reduce the overall effectiveness of their hedging strategies. This could lead to greater volatility exposure, especially during market corrections or unexpected geopolitical events.
Increased Volatility
In the absence of weekly expiry contracts, the market could see larger price movements on the expiry date itself as traders will accumulate larger positions, waiting for the monthly expiry. This concentrated positioning could trigger sharp market moves and affect long-term investors who may not have any interest in short-term fluctuations.
3. Impact on Institutional Traders and Market Makers:
Institutions play a crucial role in providing liquidity and maintaining market efficiency. The proposed removal of weekly expiries could have a disproportionate impact on them as well.
Decreased Liquidity
Weekly expiries drive significant volume and liquidity in the derivatives markets. Institutional traders and market makers thrive on this liquidity as it allows them to efficiently execute large trades and manage their risk. By eliminating weekly expiries, liquidity could dry up, particularly in mid- and small-cap stocks, affecting institutional trading strategies.
Strain on Algorithmic Trading Strategies
Algorithmic and high-frequency trading (HFT) strategies rely heavily on the ability to capitalize on frequent market movements. Weekly expiries give these strategies more opportunities to profit from short-term price movements and volatility. Removing them could make these strategies less effective, leading to a reduction in overall market efficiency.
Impact on Risk Management
Institutions often use weekly expiry contracts to manage their risk on a more granular level. The move to a monthly expiry would mean larger positions and potentially higher risk exposure. This could force institutions to adopt less efficient risk management techniques and may result in more significant market movements as they adjust their positions less frequently.
4. What Could Go Wrong for the Overall Market?
While SEBI’s proposal aims to streamline the derivatives market, the consequences could be far-reaching, affecting market dynamics in unpredictable ways.
Increased Market Volatility
Removing weekly expiries could lead to more concentrated positions building up closer to the monthly expiry, increasing the potential for sharp price swings. These swings can create artificial volatility, leading to market disruptions that can affect not just traders, but also the broader economic outlook.
Decline in Market Participation
If retail traders, institutional investors, and market makers feel that their strategies are no longer effective or that the market has become less flexible, some may choose to reduce their participation or even exit the market altogether. This reduction in participation could lead to a decline in overall market depth and efficiency.
Reduction in Innovation
Weekly expiry contracts also encourage the development of new financial products and strategies, allowing for more sophisticated approaches to trading and investment. If weekly expiries are eliminated, innovation in the derivatives market could slow down, making the market less dynamic.
Conclusion: Is the Removal of Weekly Expiries a Good Idea?
While SEBI’s proposal to remove weekly expiries aims to reduce speculation and bring more stability to the market, there are several risks involved for traders, investors, and institutions. The move could limit the flexibility of traders, reduce liquidity, and increase volatility across the market.
Before making any sweeping changes, it is essential that SEBI consults with all market participants to understand the potential risks and unintended consequences. For now, traders, investors, and institutions must stay vigilant, adapt to the changing landscape, and continue to monitor SEBI’s progress on this matter.
