📈 Quick answer: The KSE-100 is PSX's main benchmark index — the 100 largest listed companies weighted by free-float market capitalization, with representation from every sector. Launched in November 1991 at 1,000 points, it closed FY2025-26 around 180,302 points, up roughly 44% in rupee terms for the year. You can't buy the index itself — you invest through an ETF, an index-tracking mutual fund, or the constituent stocks. See the live KSE-100 tracker for today's value.

What the KSE-100 Actually Measures
The KSE-100 Index is the Pakistan Stock Exchange's flagship benchmark — a single number that tracks the combined value of the 100 largest and most representative companies listed on the exchange. It was launched in November 1991 with a base value of 1,000 points, meaning every level you see today is relative to that starting point: a reading of 180,000 means the index is roughly 180 times its 1991 base, not that it "grew 180,000%" in a simple sense (dividend reinvestment, new listings, and periodic rebasing all factor into that number over 30+ years).
When a news bulletin says "the KSE-100 closed up 900 points," it's reporting the change in this composite value — driven by price moves in the underlying 100 stocks, weighted by how much of each company's shares are actually available for public trading.
How the KSE-100 Is Calculated
Since October 2012, the KSE-100 has used a free-float market capitalization methodology. "Free float" means only the shares actually available for public trading count toward the calculation — shares locked in with sponsors, directors, government holdings, or other non-tradeable blocks are excluded. This matters because a company can have a huge total market cap but a small free float, in which case it should move the index less than its raw size suggests.
The index divisor is the mechanism that keeps the index comparable over time. Whenever a constituent issues bonus shares, buys back stock, gets added or removed, or has any other corporate action that changes its share count without changing underlying value, PSX adjusts the divisor so the index only moves because of genuine price changes — not because of share-count mechanics.
How Companies Get In (and Kicked Out)
PSX doesn't just pick the 100 biggest companies by size. The selection follows two rules, applied across all PSX sectors (excluding open-end mutual funds and ETFs):
- Sector rule: the single largest company by free-float market cap from each PSX sector is automatically included, guaranteeing every industry has at least one representative.
- Capitalization rule: the remaining slots (to reach 100 total) are filled by whichever companies have the largest free-float market cap, regardless of sector.
Companies on the Defaulters' Counter, or suspended/declared Non-Tradable in the six months before a review, are excluded entirely. PSX recomposes the index twice a year — reviewed on the last working day of February (effective the first working day of April) and the last working day of August (effective the first working day of October) — so the 100 names in the index today aren't fixed; they shift as companies grow, shrink, list, or delist.
What's Actually in the Index Today
Because selection is driven by free-float size, the KSE-100 is heavily tilted toward Pakistan's largest, most liquid sectors — commercial banks and oil & gas exploration alone account for more than half the index's weight.
| Sector | Role in the index |
|---|---|
| Commercial Banks | Largest single sector — about 29% weight |
| Oil & Gas Exploration (E&P) | Second-largest — banks + E&P together >50% |
| Cement | Major weight, cyclical with construction demand |
| Fertilizer | Major weight, defensive/agri-linked earnings |
| Power, Oil Marketing, Tech & others | Remaining weight spread across ~30 sectors |
This concentration is why a State Bank policy-rate decision or an international oil price swing can move the entire KSE-100 far more than, say, a change affecting the textile or pharmaceutical sectors — banks and E&P names simply carry that much more index weight.
KSE-100 vs KSE-30 vs KMI-30
PSX publishes several related indices, and it's easy to mix them up:
| Index | What it tracks |
|---|---|
| KSE-100 | 100 companies, free-float weighted, ~70-80% of total PSX free-float market cap |
| KSE-30 | 30 most liquid conventional stocks, free-float weighted |
| KMI-30 | 30 most liquid Shariah-compliant stocks (screened by Al-Meezan) |
KSE-100 is the broadest snapshot of the market as a whole. KSE-30 strips that down to only the most actively traded conventional names. KMI-30 applies the same "most liquid" idea but restricts the universe to companies that pass Islamic screening — acceptable debt-to-asset ratios, limited interest income, and no involvement in prohibited business activities. If you want a Shariah-compliant way to track the broader market, KMI-30 (not KSE-100) is the relevant benchmark.
Crashes, Milestones & FY26's Record Run
The KSE-100's 30-plus year history has been anything but a straight line:
| Period | What happened |
|---|---|
| Nov 1991 | Index launched at a base of 1,000 points |
| Dec 2007 | Pre-crisis high near 14,814 points |
| 2008 | Global financial crisis — index fell roughly 58% for the year |
| Jan-Mar 2020 | COVID-19 crash — fell from ~43,218 to ~27,200 in about two months |
| 2024 | Best year on record — gained roughly 84%, crossed 83,531 points |
| 2025 | Gained a further ~51% |
| Jan 2026 | Touched a fresh all-time high above 189,000 points |
| Mar 2026 | Steepest single-day fall on record (~9.6%) amid a Middle East-linked oil price shock |
| FY2025-26 close | ~180,302 points — up ~44% in PKR, ~46% in USD terms |
Put together, FY24-FY26 was a historic three-year run: the index gained roughly 335% in rupee terms over those three fiscal years — outperforming gold, the US dollar, and fixed-income alternatives like T-bills and Defence Savings Certificates in each of the three years, helped by macroeconomic stability under Pakistan's IMF program, record trading volumes, and renewed access to international debt markets.

💡 Why this matters: Big three-year gains like FY24-FY26 don't repeat indefinitely, and the March 2026 single-day drop is a reminder of how fast sentiment can reverse. Past returns are a description of what happened, not a promise of what's next.
How to Actually Invest in the KSE-100
You cannot buy "the KSE-100" itself — it's a benchmark, not a tradeable product. To get exposure that behaves like the index (or a slice of it), Pakistani investors typically use one of three routes:
| Route | How it works |
|---|---|
| ETFs | Buy units of UBL Pakistan Enterprise ETF, Meezan Pakistan ETF, or NBP Pakistan Growth ETF through a brokerage account — they trade like shares, with real-time pricing during market hours and brokerage commission of roughly 0.15% per trade |
| Index-tracking mutual funds | Subscribe directly through an asset management company (NBP, UBL, Meezan, MCB, and others run index or near-index equity funds); priced once daily via NAV, with a same-day cut-off time each AMC sets for buy/sell orders |
| Direct constituent stocks | Open a CDC/brokerage account and buy individual KSE-100 companies yourself in proportion to their index weight — most control, but more effort and higher transaction costs to stay diversified |
Overseas Pakistanis can invest in PSX-listed securities from abroad through a Roshan Digital Account (RDA), without needing to be physically present in Pakistan to open a brokerage relationship.
Because the ETFs and most index-style equity funds hold largely overlapping top constituents, the practical difference between them comes down to expense ratio and how closely each one's specific benchmark (not all three ETFs track identical baskets) matches your intent, rather than dramatically different returns.
🧮 Averaging in reduces timing risk: Given how sharply the KSE-100 can swing (see the history above), investing a fixed amount every month rather than all at once smooths out entry price. Use the SIP Calculator to project how a monthly investment into equities could grow over time.
Risks Worth Understanding
- Concentration risk: banks and E&P alone are over half the index, so a single sector shock (interest rate policy, oil prices) can drag the whole benchmark down.
- Volatility: the KSE-100 has fallen 30%+ in weeks more than once — most recently a ~37% drop during the 2020 COVID crash and a record single-day fall in March 2026.
- No capital guarantee: unlike a bank deposit or National Savings certificate, there's no principal protection — the index can close a year lower than it started.
- Timing risk near highs: after a run like FY24-FY26's ~335% gain, lump-sum entry at elevated levels carries more downside risk than gradual entry.
Tax & Zakat on Stock Market Gains
Gains from selling listed shares, ETF units, or mutual fund units in Pakistan fall under FBR's Capital Gains Tax (CGT) regime, with the applicable rate depending on your holding period and filer/non-filer status under the current Finance Act. Use the Capital Gains Tax Calculator to estimate what you'd owe on a specific stock or fund sale for the current tax year.
Separately, shares and mutual fund units held as investments are generally zakatable at their market value once your total zakat-eligible wealth crosses nisab — the Zakat Calculator includes stocks and mutual funds alongside gold, silver, and cash in its nisab check.
