# Is Altaba Inc’s (NASDAQ:AABA) PE Ratio A Signal To Buy For Investors?

Altaba Inc (NASDAQ:AABA) is currently trading at a trailing P/E of 2.6x, which is lower than the industry average of 29.1x. While this makes AABA appear like a great stock to buy, you might change your mind after I explain the assumptions behind the P/E ratio. Today, I will break down what the P/E ratio is, how to interpret it and what to watch out for. Check out our latest analysis for Altaba

### Breaking down the Price-Earnings ratio

A common ratio used for relative valuation is the P/E ratio. It compares a stock’s price per share to the stock’s earnings per share. A more intuitive way of understanding the P/E ratio is to think of it as how much investors are paying for each dollar of the company’s earnings.

Formula

Price-Earnings Ratio = Price per share ÷ Earnings per share

P/E Calculation for AABA

Price per share = \$70.08

Earnings per share = \$26.834

∴ Price-Earnings Ratio = \$70.08 ÷ \$26.834 = 2.6x

The P/E ratio itself doesn’t tell you a lot; however, it becomes very insightful when you compare it with other similar companies. We preferably want to compare the stock’s P/E ratio to the average of companies that have similar features to AABA, such as capital structure and profitability. A common peer group is companies that exist in the same industry, which is what I use below. Since it is expected that similar companies have similar P/E ratios, we can come to some conclusions about the stock if the ratios are different.

AABA’s P/E of 2.6x is lower than its industry peers (29.1x), which implies that each dollar of AABA’s earnings is being undervalued by investors. Therefore, according to this analysis, AABA is an under-priced stock.

### Assumptions to be aware of

However, before you rush out to buy AABA, it is important to note that this conclusion is based on two key assumptions. The first is that our “similar companies” are actually similar to AABA. If the companies aren’t similar, the difference in P/E might be a result of other factors. For example, if you are inadvertently comparing lower risk firms with AABA, then AABA’s P/E would naturally be lower than its peers, since investors would value those with lower risk with a higher price. The other possibility is if you were accidentally comparing higher growth firms with AABA. In this case, AABA’s P/E would be lower since investors would also reward its peers’ higher growth with a higher price. The second assumption that must hold true is that the stocks we are comparing AABA to are fairly valued by the market. If this assumption does not hold true, AABA’s lower P/E ratio may be because firms in our peer group are being overvalued by the market.

### What this means for you:

If your personal research into the stock confirms what the P/E ratio is telling you, it might be a good time to add more of AABA to your portfolio. But keep in mind that the usefulness of relative valuation depends on whether you are comfortable with making the assumptions I mentioned above. Remember that basing your investment decision off one metric alone is certainly not sufficient.
