A Low P/E Does Not Always Mean Cheap: Four Traps the Ratio Hides on the Tehran Exchange

One sentence gets repeated endlessly in the market: a low P E means the stock is cheap. But that sentence is incomplete at best, and expensive at worst. Karbon traded at five point one on the thirteenth of July; its group average was twenty one point eight. The formula is simple: share price divided by earnings per share. Twelve thousand over one thousand gives twelve. The inverse says more: an earnings yield of about eight point three percent, comparable to deposit rates. Here are a few figures recorded in Tehran trading this July. Equity markets price the future, not the past, and that distinction changes everything. A commodity producer at a cycle peak books huge profit, and its ratio looks small. Selling a property also creates a large gain that never repeats the following year. Under high inflation, part of the profit is only rising inventory value, not real earnings. There are three more places where this ratio loses its meaning entirely. The natural level of the ratio moves up and down with the risk free rate. So before drawing any conclusion, ask yourself these four questions. Price to earnings is not an answer; it is itself a question. So the answer is clear: a low number means you must ask why. Do you still trust this ratio?
