What drives the P/E ratio?

Let us check the P/E Ratio for the following companies.
DMart – 111, HUL – 62, Titan – 73, Infosys – 30, Tata Steel – 5

What drives the P/E Ratio?

While it is incorrect to compare this across sectors –something should explain this diverse range of values.

There are 2 key drivers of  P/E


More stable a business, higher the valuation it gets. Assume the business grows at exactly 0%, its EPS would remain same next year, and the year after that.

Thus, if I pay Rs 200 for a stock with EPS of Rs 10, I will recover your money in 20 years.

P/E can thus be loosely interpreted as the number of years in which I will get your money back, assuming Zero growth.

Now, an investor may be confident of HUL and its business existing after 50-60 years, but may not be that confident of a Steel company, or a technology company lasting that long.


Higher the growth expectation, higher the valuation. In the above example, add growth. The EPS could be 10, 12, 15, 20 over the years.

If I get my money back faster, I may pay a premium. Firms with higher growth possibilities typically get higher valuations

Now look at CAGR in earnings from 2017 to 2022

HUL – 14%, Titan – 25%, DMart – 25%, Infosys – 9%, Tata Steel went from losses to profits (so stability becomes a key parameter)

It doesn’t mean these valuations are correct. Some of them may get de-rated over the next few years, as growth subsides.

But this partly explains how markets value the companies, and why it is not a great idea to always buy low P/E stocks. We need to understand why a certain stock is getting a lower or higher P/E
