Open any Pakistan stock screener and three numbers jump out: EPS, PE ratio, and market cap. They look simple. In practice, a "cheap" PE on one PSX sector can be expensive on another, and a rising EPS can still mean a bad investment if the balance sheet is weak.
This guide explains what each metric means on the Pakistan Stock Exchange, how sectors differ, and where beginners get fooled. It is educational research, not a recommendation to buy or sell any share.
EPS: earnings per share in plain Urdu-English
EPS (earnings per share) tells you how much profit the company earned for each ordinary share over a period, usually the last twelve months (trailing EPS) or the current financial year (forward EPS if analysts estimate it).
Formula in words: net profit attributable to ordinary shareholders ÷ weighted average number of shares outstanding.
On PSX, EPS comes from audited financial statements filed with the exchange. Always check whether the EPS is from continuing operations or boosted by one-off gains (asset sales, tax reversals, exchange gains). A single great quarter can inflate trailing EPS and make the stock look cheaper than it really is.
- Compare EPS trend over 3–5 years, not one quarter.
- Read the notes to accounts for exceptional items.
- If the company issued bonus shares, EPS is restated — old PE charts may mislead.
- Banks and insurers use different accounting; do not compare their EPS to a cement company directly.
PE ratio: price divided by earnings
PE (price-to-earnings) = current share price ÷ EPS. If a stock trades at Rs 100 and EPS is Rs 10, PE is 10x. Investors use it as a rough "how many years of current earnings am I paying for" shortcut.
On PSX, PE varies wildly by sector. Pakistani banks often trade at low single-digit to low-teens PE when earnings are strong and rate cycles favour them. Growth technology or consumer names can command higher PE if the market expects faster profit growth. Cyclical commodities (cement, steel, oil marketing) can show very low PE at the peak of a cycle — right before earnings fall.
The biggest mistake: comparing PE across unrelated sectors. A fertiliser stock at 5x and a software stock at 25x are not automatically "cheap" vs "expensive" without context.
Market cap: size, liquidity, and index weight
Market capitalisation = share price × total listed shares. It ranks companies by size: large-cap (KSE-100 heavyweights), mid-cap, and small-cap.
On PSX, market cap matters for liquidity. A small-cap with thin daily volume can have a wide bid-ask spread — your effective buy price is higher than the last traded price suggests. Large caps usually absorb bigger orders without moving the price as much.
KSE-100 index funds and passive flows concentrate on the largest names. When foreign or local funds rebalance, high market-cap stocks often see more volume. That does not make them better investments — only more liquid.
Sector PE norms on PSX (illustrative, not targets)
These ranges shift with interest rates, commodity prices, and politics. Use them as orientation, not buy signals.
- Banks: PE often compresses when earnings surge in a high-rate environment; expands when provisions rise.
- Cement & steel: low PE at cyclical profit peaks; high PE when losses or trough earnings appear.
- Oil & gas (E&P): PE tied to global oil, field production, and exploration write-downs.
- FMCG & staples: usually higher PE for stable earnings; punishments are severe if growth slows.
- Textiles: export orders, energy costs, and currency moves swing PE quickly.
- Power & utilities: regulated returns; PE reflects dividend yield expectations and tariff risk.
When PE lies on Pakistan stocks
- Loss-making company: PE is meaningless or negative — use price-to-book or wait for recovery.
- Earnings spike from one-time items: trailing PE looks artificially low.
- Rights issue pending: share count will rise; future EPS per share may fall.
- Heavy debt: two companies with the same PE can have very different risk.
- Low free float: price can be pushed by small volume, distorting market cap and PE.
A 10-minute valuation workflow for PSX
- Pull trailing EPS from the latest quarterly or annual report on PSX disclosures.
- Calculate PE and compare to the company's own 5-year average, not random stocks.
- Check market cap and average daily traded value — can you exit a position in a bad week?
- Read dividend yield alongside PE if you are an income investor.
- Cross-check news: is the low PE because the market sees a problem you missed?
- Log your thesis in a portfolio tracker before you place the order with your broker.
