Introduction
This note is the second part of the updated valuation framework for select NSE indices, building on earlier studies published:
1) On 21Apr2026 namely “How Valuations Shape Returns and Risk in Select NSE Indices” and
2) On 03May2026 namely “Valuation Changes in Broad Market and Smart Beta Nifty Indices”.
While those studies focused on valuation, returns, risk and short-term re-rating, this section focuses on current valuation positioning within a historical range.
The analysis compares current levels (as of 31May2026) against a 21-quarter baseline from Mar2021 to Mar2026 across six Nifty indices. It uses percentile-based positioning of PE, PB and dividend yield to assess whether valuations are relatively rich or attractive across segments.
Note: The idea is to update this 21-quarter framework each quarter as new data become available. For example, inclusion of the Apr–Jun2026 quarter will extend the dataset to 22 quarters in the next update, maintaining a rolling historical reference.
Section 1:
Valuation Re-rating across Largecap, Midcap, Smallcap, Low Volatility, Momentum and Quality Indices (31Mar2026 – 31May2026):
This note updates the earlier valuation framework by examining how select NSE / Nifty indices have moved from end-Mar2026 to end-May2026, focusing on Midcap 150, Smallcap 250 and Nifty 200 Quality 30.
The objective is to decompose recent price gains into PE re-rating and PB movement, and assess whether valuation changes are being driven by earnings support or multiple expansion.
While there are six Nifty indices included in the two charts below, let us focus on three indices, namely, Nifty Midcap 150, Nifty Smallcap 250 and Nifty 200 Quality 30, for our short analysis.
Across Nifty Midcap 150, Nifty Smallcap 250 and Nifty 200 Quality 30, price gains over the period have been accompanied by varying degrees of PE expansion / contraction and PB expansion.
Data are fascinating. Sometimes.
In the past two months (31Mar2026 – 31May2026), Nifty Midcap 150 PE ratio has fallen, while the price index itself has risen.
In contrast, Nifty Smallcap 250 index's PE expansion is much faster than the rise in underlying index.
A. Midcap index:
The Nifty Midcap 150 index gained 16.2 per cent over the period under review (end-Mar2026 to end-May2026). Despite the rise in prices, its PE ratio declined by 5.5 per cent. This suggests that earnings grew faster than stock prices.
The implied earnings contribution is approximately 21.7 per cent, offset by valuation compression. The rally appears to have been driven primarily by fundamentals rather than multiple expansion.
Midcap returns appear earnings-driven, but the precise contribution cannot be directly verified without the exact EPS aggregation methodology and update timing used by NSE India.
One big assumption here is: NSE India and Nifty Indices are in the habit of updating all the earnings without any time lag.
B. Smallcap index:
The Nifty Smallcap 250 index advanced 18.9 per cent during the same period. Its PE ratio, however, expanded by a much larger 30.2 per cent. This indicates that valuation rerating contributed more to returns than earnings growth.
The implied earnings contribution is nearly minus 11.3 per cent, meaning earnings lagged the increase in prices. Future performance may depend on earnings catching up with elevated valuations.
Why the big contrast? Midcap and Smallcap indices delivered similar returns.
Yet the source of those returns is completely different.
Midcaps:
Return driven by earnings.
Valuation becoming more reasonable.
Risk profile improving.
Smallcaps:
Return driven by multiple expansion.
Valuation becoming richer.
Risk profile increasing.
That distinction matters because earnings-driven rallies tend to be more durable than valuation-driven rallies.
C. Quality index:
The Nifty 200 Quality 30 index delivered a return of 10.5 per cent. Its PE ratio increased by 5.5 per cent, indicating moderate valuation expansion. The implied earnings contribution is therefore nearly 5 per cent.
Both earnings growth and valuation rerating appear to have contributed to performance. Compared with small caps, the return profile for Quality index looks more balanced and fundamentally supported.
Overall interpretation:
Broad Market Indices:
The broad market presents a mixed picture beneath the surface. Midcaps are being supported primarily by earnings growth, while smallcaps are benefiting mainly from valuation expansion / re-rating.
Similar price returns are therefore being driven by very different underlying factors. Overall, fundamentals appear stronger in midcaps, whereas smallcaps are becoming increasingly dependent on sentiment and liquidity.
Smart Beta Indices:
The smart beta segment appears to have better earnings support than the broader smallcap space. The Quality index has delivered returns through a combination of earnings growth and moderate PE expansion, while Momentum has relied more heavily on rerating.
This suggests that quality stocks still retain relatively balanced valuation support. Overall, Quality appears better positioned than Momentum if market conditions remain stable.
Note on implied earnings contribution:
In the investment industry, it is a standard practice to use phrases, like, earnings growth, earnings contribution, or fundamental contribution.
To be on the safer side, the author has used the term 'implied earnings contribution,' since it is inferred from index return and valuation changes rather than measured directly from reported earnings.
In practice, these terms generally convey the same underlying idea: the portion of return attributable to growth in earnings rather than changes in valuation multiples.
To put simply, at the market index level:
Price Return ≈ Earnings Growth + Multiple Expansion
At the stock level:
Price Return ≈ EPS Growth + Multiple Expansion
One could also say:
Earnings Component ≈ Price Return − Multiple Expansion.
Two charts below:

2) Chart showing PE and PB Expansion versus Index Returns (31Mar2026 – 31May2026) >
Section 2:
Current Valuation Positioning vs 21-Quarter Historical Range:
Section 1 showed how valuations evolved over the period from 31Mar2026 to 31May2026, decomposing index-level returns into earnings contribution and valuation re-rating across broad market and smart beta segments.
That analysis helped explain the drivers behind the recent move in different parts of the market.
Building on that, Section 2 shifts the focus from movement to positioning.
Instead of looking at how valuations changed over time, it examines where current valuations (as of 31May2026) stand within their own 21-quarter historical range, using percentile-based comparisons across the same six Nifty indices.
Across the six Nifty indices, the current valuation versus the 21-quarter historical range shows a clear divergence between large caps, cyclicals and factor strategies (see two charts below for data).
Broad Indices:
Large-caps (Nifty 50) stand out as the most comfortable segment, with both PE and PB below their lower quartile and dividend yield above the upper quartile. Large caps appear to be cheaper compared to their recent history versus other segments.
Mid-cap stocks (Nifty Midcap 150) appear more neutral on earnings valuation, but expensive on book value and weak on yield. This suggests that while earnings-based valuation is not stretched, market seems to be pricing in strong growth expectations.
Small-cap stocks (Nifty Smallcap 250) are the most stretched among broad indices, with PE above the 75th percentile and yield near historical lows. This indicates that recent performance has pushed valuations into richer territory relative to their own history.
Smart beta Indices:
Among the so-called smart beta indices, the picture is more mixed. Low Volatility sits close to its historical median, reflecting relatively balanced valuation conditions, while Momentum is also near median but with subdued yield, indicating continued preference for growth-oriented exposure without extreme valuation stress.
As is well known, Quality index stands at premium valuation, with PE around median levels but PB above the 75th percentile, highlighting persistent willingness to pay for balance sheet strength and earnings stability.
Overall, the six-index framework shows a clear valuation divergence: large caps appear most attractive on a historical basis, mid-caps and quality sit in a fair-to-rich zone depending on the metric, while small-caps and parts of the growth/cyclical space reflect elevated valuation pressure after recent re-rating.

Shortcomings of the analysis
First, the framework is based on a relatively short history of 21 quarters, which is not enough to fully capture multiple full market cycles such as deep bear markets or extended bull phases.
Second, the analysis is purely valuation-based and does not explicitly incorporate macro variables such as interest rates, inflation, liquidity conditions, growth prospects or risk premia. These factors can significantly influence both valuation levels and their interpretation across cycles.
Third, the study relies on index-level aggregates, which can hide significant internal dispersion. Within each index, sector and stock-level behaviour can vary widely.
Fourth, the framework is descriptive rather than predictive. It shows where valuations stand relative to history, but it does not establish causal relationships or provide forward return forecasts with certainty.
Conclusion
Taken together, the 21-quarter percentile framework provides a structured way to understand where current Nifty index valuations stand relative to recent history.
The current snapshot highlights a clear divergence across segments, with large-caps appearing relatively attractive, mid-caps and quality positioned closer to fair value, and small-caps reflecting elevated valuation pressure after recent re-rating.
Valuations alone do not determine near-term outcomes, especially in environments where earnings cycles, liquidity and sentiment shifts play a dominant role.
Overall, the framework is best used as a positioning guide within a broader investment process, helping to assess relative valuation comfort across market segments rather than as a standalone buy or sell signal.
