It’s the “holy grail” of investing: a value stock that also has growth.

But here’s a little secret that all great value investors know.

These holy grail stocks do exist.

And no, they’re not some $1 stock with little volume or other risky fundamentals that are traded on an over-the-counter exchange. They are companies that you and I both know but are, for whatever reason, being ignored by other investors.

Now that we know what the holy grail of investing is, how do we find them?

The #1 Secret is the PEG Ratio

Value investors often look to the price-to-earnings ratio (or P/E) as a screen for value stocks. A low P/E ratio is believed to signify that a company is undervalued.

But that’s not the only metric that signals value.

Benjamin Graham, long considered to be the “father” of value investing, found that a low price-to-earnings ratio wasn’t enough to unearth the true undervalued companies. He looked to the PEG ratio instead, which combines both value and growth; a more potent combination.

The PEG ratio is calculated by taking the price-to-earnings (P/E) ratio and dividing it by the 5-year projected growth rate.

Confused yet?

These days you don’t really need to figure it out yourself. Most financial web sites, including, provide the PEG ratio for you as a screening criterion when looking for stocks.

What’s a Good PEG Ratio?

A company that is considered fairly valued will have a P/E ratio that equals its growth rate. So the PEG will equal 1.0.

A more expensive stock will be above 1.0.

Normally, a stock with a PEG ratio under 1.0 is considered “undervalued” as that means the market is underestimating the earnings, and/or it is also growing faster than expected.

So, that’s what you should be looking for when you see the PEG ratio. You want a ratio under 1.0.

How the PEG Ratio Really Works

1) You could have a company with a P/E ratio of 30 and a projected growth rate of 15%. This company clearly doesn’t look like it’s undervalued with a P/E ratio that high. You would be right. Plugging it into the formula, you get 30/15 = PEG of 2.0. Since 2.0 is above 1.0, it is considered an expensive stock.

2) Let’s say you have a company with a P/E ratio of 40 and a projected growth rate of 50%. With a P/E of 40, it clearly seems to be a bad value. However, plugging it into the formula gives you a PEG ratio of 0.8 (40/50 = 0.8). Since that is under 1.0, it is considered undervalued. The incredible growth rate counters the high P/E ratio.

3) In our third example, a company with a P/E ratio of 10, which is well within the value parameters for most investors and is usually considered pretty cheap, has a growth rate of just 7%. Putting it into the formula gets a PEG ratio of 1.43 (10/7 = 1.43), which is much too high to be considered undervalued despite the company’s rather low P/E.
