Wanna Know| P/E Tells Us Stock Is Cheap or Expensive

Hello, tigers. @Tiger_chat told me that you wanna know when to buy the stock.

Today, I'd like to introduce an indicator help you tell whether a stock is cheap or expensive - P/E & Forward P/E.

1. How can we tell if a company's stock price is expensive or cheap?

I bet most investors have seen the word valuation.

P/E is a kind of valuation indicator and tells us whether a stock at its current market price is expensive or cheap.

  • Price to Earnings Ratio or Price to Earnings Multiple is the ratio of share price of a stock to its earnings per share (EPS).

P/E represents how many years it takes to return the capital you invested. Therefore, the lower the P/E, the more cost-effective the investment is. The most common one used by analysts is PE-TTM.

P/E (TTM) is calculated as the stock's current price, divided by a company's trailing 12-month EPS.

We can find P/E of a company on Tiger Trade app: 

You can find it on the upper side of the k-line --> click "Analysis" --> find "Valuation Analysis"

You can tell from the chart that the current P/E of $Tesla Motors(TSLA)$ is 34.77.

  • But what's the meaning of this figure? Does it mean high or low, expensive or cheap?

We can compare this number to its peers (the sector average) or compare it to itself (the historical performance).

Analysts often say a stock's valuation dropped to a historical low.

2. How can we know P/E is low or high? - Percentile

The PE percentile is a table that counts the historical P/E of a listed company.

The lower the PE percentile, the lower the P/E is compared to the majority of historical P/E. Then it means that the stock is cheaper and has a higher potential for future growth.

Generally speaking, a percentile 

  • below 20% is called undervaluation;
  • at around 50% is considered moderate valuation;
  • above 80% is called overvaluation.

In Tesla's case, its percentile is only 4.62%, which is significantly lower than its historical data.

3. How can we know the future stock price moves?

Forward P/E is a version of the ratio of price-to-earnings (P/E) that uses forecasted earnings for the P/E calculation.

Two Formulas For Comparison:

P/E TTM = Current stock price/ trailing EPS
Forward P/E = Current stock price / estimated EPS

You can also find Forward P/E on Tiger Trade app:

As a good investor, how should you use the forward P/E?

Many analysts on Wall Street believe that a good forward P/E should be lower than the current P/E ratio.

A good lesson to learn is to look for companies with forward P/E that are 25% or more below their current P/E and whose stock prices continue to grow at a healthy rate.

4. Risk warning

After reading this article, you may think that I'm encouraging you to bottom Tesla? No.

I want to remind you that P/E is a last indicator for you when you decide to buy a stock.

The steps to begin a trade are: 1. Figure out the macro environment ---> 2. Analyze an industry situation ---->3. Find a healthy company in this industry

Although Tesla's valuation is ultra-low, it's unknown to us whether its stock price will drop or not. In 2023, if the rate hike doesn't stop and the used-car segment inflation remains high, Tesla's stock price still has room to fall.

An indicator can help you understand the company and the market. But you can't rely on it.

    Thanks for sharing once again. I want to take you to another example to seek further clarification on the above. Take TSM, the analysis indicates it's PE ratio at 434. Is this correct? However, when I check under Financial, this PE ratio is expected to drop to around 14 by next FY even though there is an expected drop in growth as illustrated in the image below. How do I reconcile the two data? For that to happen (big drop in PE ratio, either the shares price sees a big drop or the earnings see a massive jump rather than a drop in earnings) Sorry, the app only allows me to include one image, so I can't share the one under analysis. It would be great if you can clarify my understanding of the data. Thanks!

      Just remember... it is probably not just TSM... Think other companies like UMC are also affected if I am not wrong... probably some common errors used in the computation among the same sector. I don't know... good to check. Thanks!

      TSM's P/E of 434 is wrong and our engineers are revising it

    市盈率代表你投入的资本需要多少年才能收回。因此,市盈率越低,投资就越划算。分析师最常用的是PE-TTM。


    市盈率(TTM)的计算方法是股票的当前价格除以公司的连续12个月每股收益。

    Thank you for your sharing. The illustrations are very clear. With Tiger app, can I instead compare the PE ratio to its peers (sector) average rather than its own historical trend? I see that under analysis, between PE and historical percentile, there is a sector average. Is that the sector average PE? Would I be able to see the sector average trend as well? In the example, Tesla started at very high historical valuation. In fact, it just turned profitable. The old earnings are mainly due to credits provided by the US government. So, this historical percentile could be misleading. I also cannot tell for Tesla case, what is its comparable sector. The one with start-up EVs only or with auto industry that does not enjoy the same US government subsidy in general. Therefore, I have wanted to explore other options to more accurately valuate Tesla, if possible.

      sorry I'm late. P/E ratio can be compared with its own historical P/E ratio but also can be compared with the industry, one is vertical comparison, the other is horizontal comparison.In terms of PE percentile, Tesla's PE percentile for 2-5 years is only about 20%, which is at a historically low value.When using PE for calculation, EPS should be given priority. When EPS gets better, valuation will decrease, while EPS gets worse, valuation will increase. So i think you should pay more attention to EPS. Because of the valuation trap.

    Agreed that indicator is not the only consideration for buying a stock.
