Nigerian Stock Market Historical Returns: What 10 Years of NGX All-Share Index Performance Teaches Investors

Estimated Reading Time: 8 minutes

Most people look at the stock market one year at a time. They see a big gain and feel invincible. They see a sharp loss and swear off stocks forever. Neither reaction is helpful.

What actually matters—what separates the investors who build wealth from those who quit in frustration—is understanding the long arc of the market. Not what happened last quarter. Not what your colleague’s stock did last week. But the real Nigerian stock market historical returns over a full decade—through good and bad years, through elections, currency fluctuations, oil price swings, and a global pandemic.

I’ve pulled together 10 completed years of NGX All-Share Index data using official year-end closing values. This isn’t a forecast. It’s a history lesson—one that reveals patterns most beginners never see. If you’re new to how the exchange works, the guide to how the NGX operates provides helpful context.

Data source: All figures are calculated from NGX All-Share Index year-end closing values published by the Nigerian Exchange Group (NGX). Raw ASI closes are available on the NGX website at ngxgroup.com under historical market data. Returns reflect price appreciation only and do not include dividends. Including dividends would increase total returns in most years.

Quick Answer: What Did the NGX Return Over the Last Decade?

The NGX All-Share Index delivered a mix of strong positive years, flat years, and negative years—exactly as you’d expect from any stock market. Over the 10 completed years from 2016 to 2025, patient investors who stayed fully invested were rewarded with significant long-term growth. A ₦1 million investment at the start of 2016 grew to over ₦5.4 million by the end of 2025, based on price returns alone. The broader lesson is consistent: staying invested through the full cycle produced far better results than trying to time entries and exits.

What the Numbers Actually Mean for You

The Best Years Followed the Worst Years

Notice 2020: a 50% gain after a sharp COVID-driven crash earlier that year. Notice 2024 and 2025: back-to-back strong returns of 37.65% and 51.19% after several years of volatility. Investors who sold during the panic locked in losses. Those who held on—or bought more—were rewarded. This pattern repeats throughout market history. The worst moments often precede the strongest recoveries. Acting on fear during downturns is one of the most costly errors, and it’s covered in the guide to common stock investing mistakes .

Negative Years Are Normal

Over this 10-year span, the NGX recorded three negative years (2016, 2018, 2019). That’s roughly one down year every three to four years. These aren’t anomalies. They’re part of the cycle. Expecting them in advance makes it far easier to endure when they arrive.

The Long-Term Direction Is Up

Despite multiple negative years and one pandemic, the All-Share Index ended 2025 more than five times higher than where it started in 2016. The key wasn’t perfect timing. It was time in the market. For strategies on building a portfolio that can endure these cycles, the beginner’s guide to Nigerian stocks is a solid starting point.

A Decade in Perspective: Growth of ₦1 Million

Here’s what a hypothetical ₦1 million investment at the start of 2016 would have looked like, assuming the investor stayed fully invested through every up and down and did not add or withdraw funds. Values are based on the annual NGX All-Share Index returns shown above.

Year	Portfolio Value
Start 2016	₦1,000,000
End 2016	₦938,300
End 2017	₦1,335,251
End 2018	₦1,097,323
End 2019	₦937,114
End 2020	₦1,405,182
End 2021	₦1,490,479
End 2022	₦1,788,304
End 2023	₦2,609,151
End 2024	₦3,591,786
End 2025	₦5,430,888

This is a simplified illustration using NGX year-end ASI closes. It does not include dividends, brokerage fees, or taxes. Real results would vary.

The journey wasn’t smooth. There were years when the portfolio shrank—sometimes below the starting amount. But the patient investor who stayed seated more than quintupled their money over the decade, without adding a single naira beyond the initial investment.

What Drove the Big Moves?

Policy and Politics

Election cycles repeatedly influenced the market. Pre-election uncertainty (2018–2019) drove sell-offs. Post-election clarity and reform announcements (2023–2024) drove significant rallies. Government decisions on subsidies, forex, and fiscal policy have immediate and visible effects on stock prices.

Oil and Currency

Nigeria’s dependence on oil means the NGX often moves with crude prices. When oil prices rise, government revenues improve, the naira stabilises, and equities tend to benefit. When oil crashes or the naira weakens sharply, the market feels the pressure. The Nigerian Inflation Rate Tracker helps investors monitor the real returns of their portfolios against rising prices.

Global Shocks

The COVID-19 crash of 2020 and subsequent recovery showed how connected the NGX is to global events. But it also showed the market’s resilience. Companies adapted, earnings recovered, and the index reached new highs within two years.

The Single Most Important Lesson

If you take nothing else from this data, take this:

Time in the market beats timing the market.

The investors who came out ahead over the last decade weren’t the ones who predicted the 2020 recovery or the 2023 rally. They were the ones who stayed invested through all of it—the boring years, the painful years, and the exciting ones. The ₦10,000 small money plan shows how even modest, consistent investing can harness this long-term growth.

Frequently Asked Questions

What is the average return of the Nigerian stock market?

Over the 10 completed years from 2016 to 2025, the annualised return lands in the low double digits, though individual years varied dramatically from -17.82% to +51.19%. Including dividends would increase this figure.

Has the NGX ever had a negative year?

Yes. Three of the 10 completed years (2016, 2018, 2019) were negative. Negative years are normal in every stock market globally.

What was the best year for the NGX recently?

2025 delivered a 51.19% return, the strongest in the decade analysed. 2020 (+50.03%) and 2023 (+45.90%) also posted exceptional gains.

Should I invest based on historical returns?

Historical data shows patterns, but it does not predict the future. Use it to understand what’s normal—not to guess what comes next.

Do these returns include dividends?

No. The figures above reflect price appreciation only, calculated from NGX year-end ASI closes. Dividends would add meaningfully to total returns, especially from high-yielding banking stocks. For more on this, see the best dividend-paying stocks in Nigeria guide.
