Why Stock Valuation Matters on the PSX
The Pakistan Stock Exchange (PSX) offers many opportunities for value investors, but only if you know how to separate undervalued gems from overvalued traps. Stock valuation is the process of determining the intrinsic worth of a company's shares. Without it, you're speculating, not investing. In Pakistan's market — where institutional research is limited and price volatility is high — knowing how to value stocks yourself gives you a significant edge.
Method 1: The Graham Number
Named after Benjamin Graham, the father of value investing, the Graham Number provides a quick way to estimate the maximum price a defensive investor should pay for a stock. The formula is: Graham Number = √(22.5 × EPS × Book Value per Share). The 22.5 multiplier comes from Graham's rule that P/E should not exceed 15 and P/B should not exceed 1.5 (15 × 1.5 = 22.5). For PSX stocks, we often adjust this to reflect Pakistan's higher inflation and interest rate environment.
Method 2: Discounted Cash Flow (DCF)
DCF valuation projects a company's future free cash flows and discounts them back to their present value. This is the most theoretically sound valuation method but requires more assumptions. For PSX companies, we typically use a two-stage DCF model: project cash flows for 5-10 years, then calculate a terminal value. The discount rate should reflect Pakistan's risk-free rate (T-Bill yield) plus an equity risk premium.
Method 3: P/E Relative Valuation
This method compares a stock's P/E ratio to its sector average or historical average. On the PSX, sector P/E varies widely — banks have typically traded at 7-10x earnings while technology stocks have traded at 12-18x. A stock trading below its sector average P/E may be undervalued, but always check if the discount is justified by weaker fundamentals.
Method 4: Dividend Discount Model (DDM)
The DDM values a stock based on the present value of its expected future dividends. This works well for PSX companies with consistent dividend histories like OGDC, FFC, and MCB. The formula is: Stock Value = Expected Dividend per Share / (Required Rate of Return - Dividend Growth Rate). For Pakistani stocks, use a required return of 15-20% to reflect the higher risk premium.
Where the Inputs Come From
Every model needs a few numbers from the company's own financial statements: earnings per share (at the bottom of the income statement), book value per share (equity attributable to shareholders divided by shares outstanding), free cash flow (cash from operations minus capital expenditure), dividends per share and net debt. Listed companies publish quarterly and annual reports on the PSX Data Portal (dps.psx.com.pk) and on their own websites. Use the latest twelve months of earnings where you can, and note the date of every figure: a valuation is only as current as its inputs.
Putting It All Together
Professional investors on the PSX use multiple valuation methods to triangulate a stock's fair value. If the Graham Number, DCF value, P/E target, and DDM value all point to a similar range, you can be more confident in your valuation.
