In India, the traditional approach to money has always been about safety first. Ask anyone where to invest and you’ll hear:
“Fixed deposits are safe.”
“Buy gold, it never fails.”
“ULIPs are a good combo of insurance and investment.”
But the moment you mention the stock market or an index fund, the reaction is usually:
"Too risky!"
Well, are they ?
Let’s break it down from the basics — and you’ll see why index funds, particularly the Nifty 50, are far more reliable than most people think.
Myth #1 : Index Funds are too Risky !?
What Is a Stock Market Index?
A stock market index is a curated list of stocks that represent a specific part of the market. Think of it like a scoreboard showing how a segment of the market is doing.There are different indexes based on company size, sectors, or strategies.Some well-known Indian indexes include:
Nifty 50 – Top 50 large-cap companies on the NSE
Sensex (BSE 30) – Top 30 companies on the BSE
Nifty Next 50 – Next 50 companies after Nifty 50 (potential future leaders)
Nifty Bank – Top banking sector companies
Nifty Midcap 150,
Nifty Smallcap 250 – Covering mid and small-sized firms
So, What Is an Index Fund?
An index fund is a type of mutual fund or ETF that simply invests in the same stocks that make up a specific index — in the same proportions.So if you invest in a Nifty 50 index fund, your money gets spread across the top 50 companies in India, automatically.You don’t need to choose individual stocks or time the market — the fund just mirrors the index.
Introducing the Nifty 50
The Nifty 50 Index was launched on November 3, 1995, and is India’s most recognized stock market index. It tracks 50 of the largest, most stable, and most traded companies listed on the National Stock Exchange (NSE).These are not startups or speculative bets. These are well-established market leaders from sectors like banking, IT, FMCG, oil & gas, automobiles, and more.It was originally calculated using full market capitalization, but since June 26, 2009, it uses the free-float market cap method — giving more weight to stocks with higher public shareholding.
12 Companies That Have Been in the Nifty 50 Since Inception
Some companies have stood the test of time and remained in the index since 1995:
Reliance Industries Ltd.
HDFC Bank Ltd.
Housing Development Finance Corporation Ltd. (HDFC)
ICICI Bank Ltd.
Hindustan Unilever Ltd.
ITC Ltd.
State Bank of India
Bajaj Auto Ltd.
Tata Motors Ltd.
Tata Steel Ltd.
Hindalco Industries Ltd.
Larsen & Toubro Ltd.
These are names every Indian recognizes — market leaders who have created massive shareholder wealth over the years.
What Happens When You Invest ₹1,000 in a Nifty 50 Index Fund?
Let’s say you invest ₹1,000 in a Nifty 50 index fund.You’re not putting that entire amount into one company. Instead, your money is automatically split across all 50 companies in the Nifty 50 index — the biggest and most influential listed companies in India.
But here’s the key: It’s not divided equally. Instead, the investment is allocated based on something called free-float market capitalization.
What is Free-Float Market Cap?
Free-float market cap means the total value of shares available for public trading — excluding promoter or government holdings.So companies with larger free-float market caps get a bigger share of your investment.
For example, if Reliance Industries makes up 10% of the Nifty 50’s weight, then ₹100 out of your ₹1,000 goes into Reliance.If a smaller company like Divi’s Labs makes up 1%, then just ₹10 goes there.This ensures that your investment reflects the structure of the Indian economy’s largest and most actively traded businesses.
In Simple Terms: It Works Like a Basket of Fruits: Imagine the index as a basket of 50 fruits (companies). Some are big like watermelons (Reliance, HDFC Bank), and some are small like oranges (Bajaj Auto, Divi’s). When you invest ₹1,000, your money gets used to buy a tiny slice of each fruit, based on its size in the basket.
You now own a little bit of all 50 companies — no picking, no guessing, no timing needed.
The benefits of this are :
Structure Diversification: You’re not betting on one company. Even if one stock falls, others can balance it out.
Automatic Rebalancing: As the index updates over time (companies go in/out), the fund automatically adjusts.
Passive, Low-Cost: No fund manager is picking stocks. The fund just tracks the index — which keeps expenses low.
So What Kind of Returns Has the Nifty 50 Delivered?
Since June 30, 1999, the Nifty 50 Total Return Index (TRI) has delivered an annualized return of 14.1% CAGR , even while going through major market crashes like:
The Dot-com burst (2000–01)
Global financial crisis (2008)
COVID crash (2020)
Geopolitical tensions and tariff-related drops (like the recent Trump tariffs)
CAGR stands for Compounded Annual Growth Rate — it’s the average annual growth your investment sees after compounding over time.
That means, ₹1,000 invested in 1999 would have grown to over ₹27,000 by 2024 and this return includes reinvested dividends, not just price growth.
But What About Risk? What Is Volatility? Yes, the Nifty 50 has shown volatility — about 22.25% annualized over time.
Volatility means short-term price swings — sometimes up, sometimes down.
But here’s the key insight, even though the index has dropped 20% or more within certain years, long-term investors still earned 14%+ annual returns.
That’s like facing turbulence during a flight — scary in the moment, but it doesn’t mean the plane isn’t going to reach its destination.
How Does It Compare to Other Popular Investments? Let’s put things side by side:
💭 "But What If There's a Market Crash and I Lose All My Money?"
This is the most common fear people have when it comes to investing in the stock market — and it’s completely understandable. Nobody wants to see their hard-earned money vanish overnight.
But to answer this fear properly, let’s not go by gut feelings or assumptions. Let’s look at what the National Stock Exchange (NSE) actually found through real data.
The NSE Study: Rolling Returns of the Nifty 50 Total Return Index :
To understand the risk of actually losing money, the NSE analyzed the Nifty 50 Total Return Index (TRI) which includes both price appreciation and dividends.
They didn’t just look at a few handpicked years. Instead, they studied rolling returns — and that makes a big difference.
What Are Rolling Returns (And Why They're Better Than Just Looking at Absolute Returns)?
Normally, people check how an index performed over one fixed period — say from January 2015 to January 2020. This is called an absolute return.
But the problem with this approach? It only tells you one outcome. What if those specific dates were unusually good or bad? That doesn’t represent every investor’s experience.
Rolling returns fix that.
Here’s how they work, instead of one fixed period, rolling returns look at every possible time window of a given length — starting from each trading day.
So if you're analyzing 5-year rolling returns, you're looking at thousands of overlapping 5-year periods — Jan 1, 2000 to Jan 1, 2005… then Jan 2, 2000 to Jan 2, 2005… and so on.
This captures all market conditions — booms, crashes, recoveries, and sideways phases. It also includes daily volatility and smooths out the emotional highs and lows.
So What Did the Data Say? Here’s what the rolling return study found:
If you had invested in a Nifty 50 index fund and stayed invested for 5 years or more, the probability that you would’ve lost money was close to zero — even with events like the 2008 crash, COVID-19, global tensions, and more.
In fact, over 80% of the time, people who stayed invested for 7 or 10 years earned more than 10% returns annually.
The Bottom Line: Time in the Market > Timing the Market
Yes, the market can crash. Yes, it can be volatile. But history clearly shows that if you stay invested long enough, those short-term shocks fade — and the long-term rewards kick in.
So the next time someone says,
“What if I lose all my money?”
You can confidently say:
“Only if you panic and exit early. Stay for 5+ years, and history is overwhelmingly on your side.”
So... Can I Still Lose Money If There's a War or Global Crisis? It’s a fair concern. After all, in the last 20+ years, the market has seen:
The Lehman Brothers collapse (2008 Global Financial Crisis)
The Russia-Ukraine war
The COVID-19 pandemic
Global inflation, interest rate shocks, geopolitical tensions — you name it.
And yet, the data from the NSE’s rolling return study clearly shows:
If you stayed invested for 5 years or more in the Nifty 50 index, your chance of losing money was almost zero. Over 7 to 10 years, more than 80% of all periods gave returns over 10% per year.
That’s not theory — that’s the actual, historical performance of the Indian stock market.
Myth #2: “The Market Is Crashing — I’ll Stop My SIPs!”
This is the next instinct most people have when they see red in their portfolio: “I should stop investing until things settle down.”
But let’s think about this logically for a second. If you ask your parents or anyone who invests in gold, real estate, or even buys groceries:
Do they like to buy things when prices are high, or when they’re low and on discount?
It’s obvious — we all prefer buying low. That’s true whether it's mangoes or mutual funds.
So here’s the irony, when the stock market falls, it’s literally going on sale — and that’s exactly when most people stop investing.
Think of It Like This: You're Still Accumulating the Asset When you’re doing SIPs into an index fund, your goal isn’t just short-term returns. You’re in the accumulation phase — trying to collect as many units as possible while prices are reasonable.
So if prices drop:
You get more units for the same SIP amount
You lower your average cost per unit
You position yourself for higher long-term gains when the market recovers (and it always has)
Low markets are not a reason to stop — they’re a reason to keep going (or even increase your SIPs if you can).
Real Wealth Is Built During Downturns. Ask any seasoned investor or mutual fund veteran — The investors who stayed consistent during downturns like 2008, COVID, or even recent crashes are the ones sitting on the highest returns today.
Crashes feel scary in the moment. But history shows: The best time to invest is often when everyone else is afraid.
Myth #3: "You Should Only Invest in Funds Run by Government Entities Like SBI"
This is a very common belief and one that stops many people from exploring better-performing or more efficient investment options.
The thinking usually goes something like this:
“Private companies can shut down anytime.”
“Government-backed funds are safer.”
“SBI hai toh solid hai.”
While there’s nothing wrong with SBI or any other public sector institution — this kind of logic doesn’t really apply to mutual funds or index funds. Here’s why:
Your Fund Returns Don’t Come from the Government Let’s get one thing straight:
Your mutual fund or index fund returns come from the market , not from the AMC (asset management company) running the fund.
So whether it’s:
SBI Mutual Fund
HDFC Mutual Fund
ICICI Prudential
Nippon India
UTI
Or even a brand-new AMC...
The fund manager doesn't create returns. The market does.
For example:
A Nifty 50 index fund from SBI and one from HDFC will both invest in the same 50 companies.
The returns will be nearly identical, because they’re tracking the same index.
The only difference will come from expense ratio, tracking error, and how efficiently the fund is managed — not who owns the AMC.
Government Ownership ≠ Guaranteed Safety in Market-Linked Products ! Yes, a government-owned bank like SBI might feel "safe" when you’re talking about a savings account or an FD. But once you're investing in market-linked products, whether it's:
A government-owned mutual fund (like SBI Mutual Fund)
Or a private one (like Axis, Kotak, or Mirae), they're both buying the same stocks from the same market.
So if the market crashes, even the most "trusted" PSU fund is going to show losses — just like a private one.
What Actually Matters When Choosing a Fund:
Low expense ratio (especially for index funds)
Tracking error (how closely the fund follows the index)
Consistent process, transparency, and fund management
Your investment horizon and risk profile
Not whether the company running it is a PSU or a private firm.
The Bottom Line:
Trust the process, not just the brand. You’re investing in India’s top companies through the index — not betting on whether SBI is better than HDFC.
If you still feel more comfortable with government-run AMCs, that’s totally okay — but know that it’s a preference, not a requirement for good returns.
Myth #4: "I’ll Start Investing When the Market Looks Better"
This sounds smart, but in reality? It’s a trap.
By the time things feel “safe,” the market has already recovered.
“Time in the market” beats “timing the market” every time.
Start now. Let SIPs do the work. Stay consistent. That’s how long-term wealth is built.
Final Thoughts
Index funds are not as risky as people think, provided a few key principles are followed:
Stay invested for the long term
Don’t try to time the market
Keep investing during crashes (especially via SIPs)
Choose low-cost, efficient funds
That said, index funds shouldn’t be your only asset class. A sound investment portfolio should be built around your individual goals, timeline, and risk appetite — with the right mix of equity, debt, gold, and more.
The key is to have a plan — and to stick with it, especially when the market makes you doubt it the most.
