H1: Nifty 50 Index Fund vs Nifty 50 ETF: Key Differences Explained
The Nifty 50 Index Fund vs Nifty 50 ETF comparison is primarily a comparison between two ways to gain exposure to the same benchmark. Both products track the Nifty 50, a 50-stock, free-float, market-capitalisation-weighted diversified index representing 50 large, liquid companies listed on the NSE.
However, the two products differ in how they can be bought and sold, how prices are determined, and what costs can arise during transactions. Understanding these structural differences can help you evaluate the difference between Nifty 50 ETF vs Index Fund. This article compares them for educational purposes and does not suggest that one is better than the other.
What is a Nifty 50 Index Fund?
Nifty 50 Index Fund is an open-ended mutual fund that follows the Nifty 50 Index. The index fund invests in the securities that make up the Nifty 50, with the portfolio constructed to closely track the index’s composition and weights.
The fund’s objective is not to beat the Nifty 50 index, but to track it closely, subject to tracking error.
Unlike an ETF, an index fund is not traded on a stock exchange. Asset Management Companies manage index funds, and you can transact through the fund house or third-party mutual fund platforms, such as a distributor. You can buy or redeem Index fund units at the applicable Net Asset Value (NAV), subject to applicable rules.
A Nifty 50 index fund allows you to invest either through a Systematic Investment Plan (SIP) or as a lump sum. The investment amount is then converted into mutual fund units according to the applicable NAV. NAV represents the per-unit value of the mutual fund scheme’s assets after accounting for its liabilities.
What Is a Nifty 50 ETF?
A Nifty 50 ETF is an exchange-traded fund that tracks the Nifty 50 Index. Like an index fund, a Nifty 50 ETF invests in the securities that make up the Nifty 50 to closely replicate the index’s composition and performance. It therefore also aims to provide returns close to the index, after expenses and other sources of tracking difference (will discuss this later in the article).
However, unlike an index fund, which is not traded on a stock exchange, ETF units are listed and traded on a stock exchange. ETF units are bought and sold on the stock exchange during trading hours, similar to listed shares. Thus, you need a demat and trading account to transact in ETF units on the stock exchange.
However, the ETF NAV and the traded price can differ. The NAV reflects the value of the fund’s underlying portfolio, while the market price is determined by trading activity on the stock exchange. As a result, an ETF can trade at a premium or discount to its NAV.
Nifty 50 Index Fund vs Nifty 50 ETF: Key Differences
The table below summarises the differences between the Nifty 50 Index Fund and the Nifty 50 ETF.
| Parameter | Nifty 50 Index Fund | Nifty 50 ETF |
|---|---|---|
| Structure | Open-ended mutual fund | Exchange-traded fund |
| Investment Mechanism | Purchased or redeemed through mutual fund channels | Bought and sold on a stock exchange |
| Pricing | Applicable NAV | Exchange-traded market price |
| Demat Account | Generally not required | Generally required for exchange trading |
| Trading | Mutual fund purchase/redemption mechanism | Traded during exchange trading hours |
| SIP | Commonly available through mutual fund platforms | Availability depends on the platform and investment mechanism |
| Transaction Costs | Fund expenses and applicable transaction/platform charges | Fund expenses plus applicable brokerage, bid-ask spread and other transaction/depository charges |
| Price vs NAV | Transactions occur at applicable NAV | Market price can trade at a premium or discount to NAV |
| Liquidity Consideration | Mutual fund transaction mechanism | Depends partly on exchange trading liquidity and bid-ask spreads |
Nifty 50 Index Fund vs ETF Costs
Every financial product has costs and expenses, and so do ETFs and Nifty 50 Index Funds. Both Nifty 50 Index Fund vs ETF Costs have fund-level expenses, including the applicable total expense ratio (TER). However, total costs can differ by scheme and transaction method.
When buying and selling ETF units on the stock exchange, you may also incur brokerage, applicable taxes, bid-ask spreads and other transaction charges. The bid-ask spread is the difference between the price at which you can buy an ETF unit and the price you can sell it in the market.
Therefore, Nifty 50 ETF vs Index Fund costs can vary depending on the scheme, investment amount, transaction frequency and platform used.
Tracking Error and Tracking Difference
Index funds and ETFs may not exactly replicate their benchmark’s returns because expenses, transaction costs, cash holdings, portfolio adjustments, and other factors can create differences. Tracking error measures how much the fund’s returns vary from those of its targeted benchmark.
In technical terms, tracking error measures the volatility of the difference between the fund’s NAV returns and the benchmark’s returns over time. A low tracking error generally means that the fund tracks the index well.
Meanwhile, tracking difference is the annualised difference between the return of an index and the returns of an ETF or index fund over a specific period. SEBI mandates AMCs to report tracking error daily and tracking difference monthly.
Risks of Nifty 50 ETFs and Index Fund
Because both instruments track equity indices, they are subject to market-related volatility. Since both seek to track the Nifty 50, their values can decline when the index falls. Tracking risk also applies because the fund’s returns may differ from those of the underlying index. For example, Nifty 50 index funds and ETFs may underperform the underlying index. Investors can learn more about risk in mutual fund investments and the different factors that can affect mutual fund performance.
When trading ETFs, you can also face liquidity and price-discrepancy risk. As a result, an ETF’s trading price can move away from its NAV, particularly when the ETF is illiquid or markets are volatile. The actual premium or discount depends on the ETF’s liquidity and market conditions.
Therefore, it’s important to understand both the investment risk of the Nifty 50 and the operational characteristics of the particular fund or ETF.
Conclusion
The Nifty 50 Index Funds vs Nifty 50 ETFs comparison comes down largely to how they are traded. Both are passive investment products that aim to replicate Nifty 50 performance. You can buy and redeem index funds through the mutual fund route at the applicable NAV, while you can buy and sell ETF units on stock exchanges at market-determined prices.
Both Nifty 50 index funds and ETFs have expenses and can experience tracking differences compared with the Nifty 50. Before investing, you must examine the scheme’s expense ratio, tracking error, tracking difference, transaction costs, and liquidity.
