Sensex at 40 Shows How India’s Market Has Grown Alongside the Economy
As India’s most tracked equity benchmark approaches four decades of existence, the Sensex’s long-term performance offers a revealing lens into the country’s economic journey. Since its launch in 1986, the index has delivered an annualised return of about 13.4 percent—remarkably close to India’s nominal GDP growth of nearly 13 percent over the same period.
For investors, this alignment underscores a critical point: over long horizons, equity markets tend to reflect the pace of economic expansion rather than deviate meaningfully from it. Short-term volatility may dominate headlines, but the Sensex’s long-term trajectory tells a story of compounding growth rooted in structural economic progress.
From 549 to Nearly 85,000 Reflects a Transformed Market
The Sensex was introduced at a time when India’s economy was largely closed, market participation was narrow, and access to capital was limited. On January 2, 1986, the index was set at a base value of 549. By December 2025, it had climbed to nearly 85,000, spanning liberalisation, reforms, globalisation and multiple market cycles.
This rise was not linear. The journey included phases of sharp optimism, deep corrections and prolonged recoveries. Yet, when viewed across rolling 10-, 15-, 20- and 25-year periods, the index’s returns have remained consistently positive, highlighting the power of long-term participation despite interim turbulence.

Market Drawdowns Were Deep, but Recovery Has Accelerated Over Time
India’s equity markets have endured several severe stress episodes. The Sensex witnessed peak-to-trough declines of over 30 percent during periods such as:
-
The 1995 market correction
-
The 1998 Asian Financial Crisis
-
The 2000 dotcom bust
-
The 2008 Global Financial Crisis
-
The post-crisis slowdown of 2011
-
The Covid-19 shock in 2020
The 2008 crisis marked the steepest fall, with drawdowns of nearly 55–60 percent. However, what has changed over time is not the occurrence of declines, but the speed of recovery. Earlier drawdowns took five to six years to recover, while more recent corrections—most notably in 2020—were recouped in less than a year.
According to BSE Research, this faster rebound reflects structural improvements such as electronic trading, dematerialisation, deeper liquidity and a broader investor base.
Rising Participation Has Strengthened Market Resilience
One of the most significant changes underpinning the Sensex’s stability is the expansion of market participation. Demat accounts have grown from fewer than five million in the early 2000s to well over 150 million today. Daily trading volumes have multiplied several-fold, allowing markets to absorb shocks more efficiently.
The growing role of domestic institutional investors and retail participants has reduced reliance on foreign flows during periods of stress. This internal depth has helped stabilise markets and shortened recovery cycles following major disruptions.
Calendar-Year Returns Mask Long-Term Consistency
Despite frequent volatility, calendar-year outcomes have skewed decisively positive. Historically, the Sensex has delivered positive price returns in roughly three out of every four years. When dividends are included through the Total Return Index (TRI), gains were recorded nearly 80 percent of the time.
Returns, however, tend to cluster around turning points. Weak years are often followed by sharp rebounds, creating the impression of erratic performance in the short run. Over longer holding periods, this variability narrows significantly, reinforcing the benefits of staying invested through cycles.
Index Churn Has Kept the Sensex Aligned With Economic Change
Another reason the Sensex continues to mirror economic growth is its internal evolution. Only a handful of companies from the original 1986 index remain today. Constituents have changed as industries rose, matured or declined, allowing the index to reflect shifts in India’s growth drivers.
Sector weights illustrate this transformation clearly:
-
Financial services have grown from about 22 percent of the index in 2005 to nearly 40 percent today
-
Consumer discretionary stocks have gained prominence with rising incomes
-
Traditional manufacturing and commodities occupy a smaller share
-
IT, once dominant in the early 2000s, now holds a more balanced weight
This churn has enabled the Sensex to capture successive phases of India’s development without altering its fundamental structure.
Dividends Have Played a Quiet but Powerful Role
The introduction of the Sensex Total Return Index in 1996 highlights the importance of dividends. Over the past 25 years, the Sensex TRI has compounded at about 14.3 percent, outperforming price-only returns by more than a percentage point annually.
Dividend reinvestment has contributed meaningfully to long-term wealth creation, especially during periods when price appreciation was subdued. This often-overlooked factor reinforces the case for long-term equity ownership.
What the Sensex’s 40-Year Record Ultimately Tells Investors
Across reforms, crises and cycles, the Sensex has neither consistently outpaced nor lagged India’s economy. Instead, it has tracked changes in scale, earnings capacity and corporate composition over time.
As markets evolve and participation deepens further, the benchmark’s history offers a simple but powerful lesson. Volatility is inevitable, drawdowns are unavoidable, but over extended periods, equity returns tend to converge with economic growth. For patient investors, that alignment remains the strongest argument for staying invested in India’s equity story.
