# P/E to Growth Ratio (PEG)

The PEG ratio considers the impact of earning growth on the P/E ratio. It is calculated as P/E divided by the expected earnings growth rate in percentage. Stocks with lower PEG ratios are more attractive than those with higher PEG ratios. A PEG ratio of less than one would be considered an attractive investment level.

However, the PEG ratio has several limitations:

• It assumes a linear relationship between P/E and growth.
• It does not factor in differences in risk.
• It does not account for differences in the duration of growth.

#### Example: PEG Ratio

A company with a forward P/E ratio of 9.21 and a 5-year EPS growth forecast of 12% would have a PEG ratio of 0.76 calculated as follow:

$$\text{PEG}=\frac{9.21}{12}=0.76$$

# Question

Consider a company with a forward P/E ratio of 8.20 and a 5-year EPS growth forecast of 13%. The PEG would be closest to:

1. 0.42.
2. 0.63.
3. 63.07.

### Solution

$$\text{PEG}=\frac{8.20}{13}=0.63$$

I have finished my FRM1 thanks to AnalystPrep. And now using AnalystPrep for my FRM2 preparation. Professor Forjan is brilliant. He gives such good explanations and analogies. And more than anything makes learning fun. A big thank you to Analystprep and Professor Forjan. 5 stars all the way!

Professor James' videos are excellent for understanding the underlying theories behind financial engineering / financial analysis. The AnalystPrep videos were better than any of the others that I searched through on YouTube for providing a clear explanation of some concepts, such as Portfolio theory, CAPM, and Arbitrage Pricing theory. Watching these cleared up many of the unclarities I had in my head. Highly recommended.
