MSCI Rejig Explained: How Index Changes Affect Your Portfolio and What to Do — illustrative featured image
The closing bell on February 25th was chaos, but the good kind of chaos if you were watching the right screens. At precisely 3:40 pm, trading volumes in stocks like Zomato, Jio Financial Services, and a handful of mid-cap names went vertical. This wasn't a sudden burst of insider confidence or a rogue algorithm. It was the MSCI rejig, and it reminded everyone that index providers, not just earnings reports, can move markets. For Indian retail investors, the semi-annual MSCI index rebalancing is usually a footnote. You hear about it, you see a few headlines, and then you forget about it. But the February 2025 event was different. It drove the highest closing auction volumes in months, and it left a lot of folks wondering if they missed something or, worse, if they should be doing something right now. Let's break down what actually happens, why it matters for your portfolio, and the one thing you should absolutely not do when the next rebalancing rolls around. ## What Is the MSCI Rejig, Really? MSCI is a global index provider. Think of it as the gatekeeper for international money. When a fund in New York or London wants to buy Indian stocks, they usually don't pick individual shares. They buy an MSCI India Index fund. That means the money flows into whatever stocks MSCI decides to include in its indexes. Twice a year, in February and August, MSCI reviews its lists. They add stocks that have grown big enough or liquid enough, and they delete stocks that have shrunk or become too hard to trade. This is the "rejig." If you are new to this, our earlier piece on the [MSCI rejig explained](/finance/blog/msci-rejig-explained-what-indian-retail-investors-need-to-know) walks through the basics in detail. The math is simple but the consequences are heavy. When a stock gets added to the MSCI India Index, every fund tracking that index must buy it. When a stock is deleted, every fund must sell it. We are talking about billions of dollars in forced flows. This is not discretionary buying. It is mechanical. ### The Size of the Flows Matters More Than the Direction Here is the part that surprises most retail investors. The stock that gets added doesn't just go up on the announcement day. It goes up on the implementation day, which is the last trading day of the month. The February 2025 event saw Zomato and Jio Financial see massive buying in the final 15 minutes of trading. Why? Because index funds wait until the last possible moment to execute their trades to avoid tracking error. This behavior is closely tied to how the [new stock closing auction](/finance/blog/new-stock-closing-auction-how-it-affects-your-trades-and-what-to-watch) works, where all the action gets concentrated at the end of the session. This creates a predictable pattern. Stocks being added tend to rally into the close. Stocks being deleted tend to get sold off. But here is the kicker: the moves are often temporary. The stock isn't changing its business fundamentals. It's just changing its shareholder list. ## How This Affects Indian Stocks Specifically The MSCI India Index is the gateway for foreign institutional money. When the broader index gets a new entrant, the ripple effect hits the entire market. But the impact is not uniform. With [foreign investors back in Indian markets](/finance/blog/foreign-investors-are-back-how-to-ride-the-fii-wave-in-indian-markets), the rejig takes on even more significance as these flows can amplify the price moves. ### The Inclusion Effect When a stock like Jio Financial Services gets added, it doesn't just get bought by index funds. It gets bought by active managers who benchmark against MSCI. It gets bought by derivatives desks that need to hedge. It gets bought by retail investors who see the news and think, "If the smart money is buying, I should too." This creates a momentum spike that can last anywhere from a few days to a few weeks. The stock often overcorrects on the upside before settling down. ### The Exclusion Effect The deletion side is uglier. When a stock is removed, the forced selling is brutal. The stock often drops more than it should because the sellers don't care about price. They just need to exit. If you own a stock that gets deleted, you are not just facing a sell-off. You are facing a liquidity vacuum. ### The Volume Anomaly The most visible impact is on trading volumes. As Reuters noted, the February rejig drove significant volumes in Indian stocks, with swings concentrated in the closing auction. This is a direct result of index funds executing their trades at the closing price to match the index. For a retail investor, this means the last 15 minutes of trading on rejig day are completely distorted. Prices do not reflect supply and demand. They reflect mechanical fund flows. ## What Should a Retail Investor Actually Do? This is where we get opinionated. Most financial advice about the MSCI rejig is useless. It tells you to "stay the course" and "ignore short-term noise." That is lazy advice. Here is what we actually recommend. ### 1. Do Not Chase the Inclusions If a stock gets added to the MSCI India Index, it has already run up. By the time you see the news, the institutional money has already positioned. Buying the day after the rejig is buying at the peak of the momentum spike. You are late. The stock will likely consolidate or correct in the following weeks. Instead, do this: add the stock to your watchlist. Wait for the post-rejig hangover. If the stock drops 10 to 15 percent from its rejig-day high for no fundamental reason, that is your entry point. You are buying a stock that now has permanent institutional demand. That is a good long-term hold. ### 2. Do Not Panic Sell the Exclusions If you own a stock that gets deleted, the immediate reaction is to sell. Resist that urge. The forced selling is temporary. Once the index funds are done, the stock often bounces back because the fundamentals haven't changed. The stock is just no longer part of the "cool kids" club. Evaluate the stock on its own merit. If you bought it for the business, keep it. If you bought it because it was in the index, sell it. But do not sell it on rejig day. Wait for the dust to settle. ### 3. Use the Volatility to Your Advantage The rejig creates artificial price swings. This is a gift for disciplined investors. If you have cash on the sidelines, the rejig day is a great time to place limit orders below the market price. You might catch a forced seller who is desperate to exit. ### 4. Check Your Mutual Fund Holdings This is the one that most people miss. If you hold an index fund or an ETF that tracks the MSCI India Index, you are indirectly affected. The fund manager will have to buy and sell the same stocks. This creates turnover, which can trigger capital gains taxes in a mutual fund. Check your fund's portfolio. If it holds a stock that was deleted, expect some distribution in the next quarter. ## Our Take: The MSCI Rejig Is a Distraction, Not an Opportunity Here is the uncomfortable truth. The MSCI rejig is a non-event for long-term investors. It is a transfer of shares from one set of holders to another. It does not change the underlying value of a company. The real opportunity is not in trading the rejig. It is in understanding the structural shift. Indian stocks are becoming more institutionalized. The retail investor who understands this can benefit by holding quality companies that are likely to be added to global indices over time. We recommend looking at the following: - **Zomato**: It is now a core holding in the MSCI India Index. The volatility around the rejig is noise. The food delivery business is still growing. Hold it. - **Jio Financial Services**: The inclusion was expected, but the scale of the buying was not. The stock is now a permanent part of the global investment landscape. Long-term, this is a compounding story. - **Smaller mid-caps**: Look at stocks that are on the cusp of inclusion. Companies with a market cap above $3 billion and high liquidity are the next candidates. Do your homework now, before the next rejig in August. ## The One Mistake to Avoid Do not trade the day before the rejig. The market is full of speculation. You cannot outguess the institutional flow. You will get run over. The other mistake is ignoring the tax angle. If you sell a stock on rejig day to book a profit or cut a loss, remember the holding period rules. Short-term capital gains tax on equities is 20 percent. Long-term is 10 percent. If you have held a stock for 11 months, wait a month. The tax savings will beat any rejig trade. ## FAQ ### 1. When is the next MSCI rejig? The next major review is in August 2025. The announcement usually comes in the second week of August, and the changes take effect at the end of the month. ### 2. Should I buy stocks that are being added to the MSCI index? Not immediately. Wait for the post-rejig correction. The stock will likely drop 5 to 10 percent within a month of inclusion. That is your entry point. ### 3. Does the MSCI rejig affect my mutual fund NAV? Yes, but only slightly. If your fund tracks the MSCI India Index, the rebalancing will cause minor changes in the NAV. This is normal and should not be a reason to redeem your units.
