👋🏼,

Hope you’re having a good week so far!

Here’s something that puzzled me when I first started investing:

Why do some companies have a share price that's just 5 times their earnings, while others are worth 50 times or more?

It’s not always obvious at first. Is it because one company is a bargain? Or is another just overhyped?

The answer lies in the price-to-earnings (P/E) ratio, which reflects how the market values a company’s current earnings and future potential.

The price-to-earnings (P/E) ratio tells a story - about a company’s growth potential, risk, and how the market views its future. But understanding why some stocks have low P/E ratios while others seem sky-high takes a little unpacking.

Today, I’ll break down:

  • What the P/E ratio really means

  • How the P/E ratio is calculated (with an example)

  • 📹 Explainer

  • Low P/E and High P/E case studies 🤓

  • Is P/E ratio a good indicator for deciding which stocks to invest in?

Let’s jump in!
