Master the PE/PB heatmap — read percentiles, spot cheap and expensive zones, and time your investments

What You Will Master

The Valuation page shows the Nifty 50's Price-to-Earnings (PE) and Price-to-Book (PB) ratios from 1999 to present — the most complete historical context available for Indian market-level valuation. A single glance tells you whether the market is cheap, expensive, or near its long-run average. No login required.

What This Guide Covers:

  1. The toggle — switching between PE Ratio and Price-to-Book views
  2. The snapshot panel — current value, 25-year min/avg/max, and percentile position
  3. The percentile bar — green/amber/red colour coding based on historical position
  4. The year × month heatmap — every month since 1999 colour-coded from cheap to expensive
  5. Reading market cycles — spotting peaks and troughs across 25 years of data
  6. PE vs PB — when to use each and how they complement each other

Who This Is For:

  • Long-term investors — assess whether to increase or reduce market exposure based on historical context
  • SIP investors — understand whether lump-sum additions make sense at current levels
  • Traders — combine with MMI for a sentiment + valuation dual confirmation before entering the market
What does a percentile of 25 or below indicate on the valuation page?
The market is in the cheapest quartile of its 25-year history — the current PE or PB reading is lower than 75% of all prior monthly readings. The snapshot bar and current value turn green. Historically, these are the best long-term entry points.
How does the heatmap colour scale work?
Each cell is coloured on a continuous green → yellow → red scale. Green cells = low PE/PB (cheap relative to range). Red cells = high PE/PB (expensive). The colour is computed by mapping the cell's value between the dataset's minimum and maximum.
Why might PE ratio be misleading during recessions or earnings crashes?
PE = Price ÷ Earnings. In a recession, earnings collapse before prices do — this makes PE look artificially high (expensive) even though prices may be falling. Price-to-Book is more reliable in these moments because book value is more stable than near-term earnings.
What does the amber outline on a heatmap cell indicate?
The amber (gold) outline marks the current month in the grid — so you can immediately locate where today sits in the full historical picture without having to scan every cell.
What is the 25-year average Nifty PE, and why does it matter?
The average shown in the snapshot is the mean PE (or PB) computed across all monthly data from 1999 to present. Buying below this average has historically produced better 3-year returns than buying above it. The percentile bar shows exactly how far above or below average you are today.
Should you sell everything when the valuation page shows red (expensive)?
No. Markets can stay expensive for years — the 2014–2018 bull run saw consistently above-average PE ratios. Valuation is a tool for calibrating position size and new entry decisions, not a binary signal. In Extreme Greed + high PE, reduce new lump-sums; don't exit existing compounders.
When is Price-to-Book (PB) more useful than PE ratio?
PB is more useful when earnings are distorted — during recessions, recovery phases, or for capital-intensive sectors (banks, metals, real estate). Book value is more stable than earnings, making PB a more reliable anchor for sectors with cyclical profits.
How do you combine Valuation with MMI for better decisions?
Look for dual confirmation: Valuation in the cheap zone (green, ≤25th percentile) + MMI in Fear or Extreme Fear = highest-confidence entry window. Both tools agree the market is depressed. Single confirmation (only one is green) is useful but less powerful than both aligning.

What Is the Market Valuation Page?

The Finmagine Market Valuation page shows the historical Nifty 50 Price-to-Earnings (PE) and Price-to-Book (PB) ratios from 1999 to the present — over 25 years of monthly data displayed in a single year-by-month heatmap.

The core question it answers: Is the Indian market cheap or expensive right now compared to its own history?

It does not tell you whether the market will go up or down tomorrow. It tells you where today's valuation sits on a 25-year spectrum — which is the most honest and useful context for long-term investment decisions. The page is free and requires no login.

Key Concept: Valuation context does not predict short-term direction — but over 3–5 year horizons, starting valuation is the single strongest predictor of returns. Buying a broad index at cheap valuations (green zone) has historically produced much better long-term returns than buying at peak valuations (red zone).

The Two Metrics — PE and PB

Click the toggle at the top of the page to switch between the two views:

MetricWhat it measuresBest used when
PE Ratio Nifty 50 price divided by trailing 12-month earnings per share. Measures how much investors pay for each rupee of current profit. Normal market conditions when corporate earnings are stable and growing. The most widely tracked valuation metric globally.
Price to Book (PB) Nifty 50 price divided by the book value (net assets) per share. Measures how much above (or below) asset value investors are paying. When earnings are distorted — recessions, recovery phases, or when assessing capital-intensive sectors (banks, metals, real estate). Book value is more stable than earnings.
Use Both Together

If PE shows expensive but PB shows average, it may mean earnings are temporarily compressed (PE overstated). If both show cheap simultaneously, it is a stronger conviction signal. The two metrics act as a cross-check on each other.

Reading the Snapshot Panel

At the top of the page, the snapshot panel gives you an instant summary of where today's reading stands:

Cheap
Below avg
Average
Above avg
Expensive

Heatmap colour scale — each cell transitions continuously from green (cheapest) to red (most expensive) based on the full 25-year range.

Reading the Year × Month Heatmap

The heatmap is the most powerful part of the page. Each row is one calendar year (1999 to present). Each column is one month (Jan through Dec). Each cell shows the Nifty 50 PE or PB for that specific month, colour-coded from green (cheap) to red (expensive).

The current month has an amber outline so you can locate today's reading instantly without scanning every cell.

What to look for in the heatmap

5-Step Workflow

1

Choose your metric

Start with PE Ratio for the standard view. Then switch to Price-to-Book to cross-check. If both show the same colour, the signal is stronger.

2

Read the snapshot percentile

The percentile bar immediately tells you whether today is cheap (<25th), average (25–75th), or expensive (>75th) vs history. This is the single most important number on the page.

3

Find the current month in the heatmap

Locate the amber-outlined cell — that is today. Look at the row above it (prior year, same month) and the row below. How does today compare to the same calendar month in prior years?

4

Identify historical analogues

Find the last time the market was at a similar colour shade. Check what happened in the 2–3 years that followed. Not a prediction — but useful context for calibrating expectations.

5

Cross-reference with MMI

Open the Market Mood Index to see if sentiment confirms the valuation signal. Cheap valuation + Extreme Fear sentiment = highest-conviction window. Expensive valuation + Extreme Greed = most cautious.

Pro Tips

Don't use Valuation as a sell trigger

Markets can stay expensive for years in a bull run (see 2014–2018). Valuation at expensive levels means you should be more selective about new lump-sum entries — not that you should exit quality compounders that keep growing earnings.

PE at extremes can mislead — PB can anchor you

In the March 2020 crash, PE looked expensive initially because earnings had already been cut for the quarter. PB immediately showed cheap. This is the best case for checking both metrics every time — they give complementary perspectives.

This is market-level data only

Nifty 50 PE/PB reflects the aggregate valuation of the 50 largest Indian companies. Individual stocks within the index can be cheap or expensive regardless of where the broad index sits. Always combine this macro view with stock-level analysis.
