Price Earnings (PE) ratio is one
of the most commonly used valuation metrics by investing community to assess
whether a company is undervalued or overvalued or to give us an indicative
intrinsic value of the company/business.
Price Earnings ratio = Price (P)
/ Earnings (E)
In a nutshell, it tells us how
many years for us to recover our investment if we invest in company or how much
you are willing to pay per dollar of earnings. The inverse of PE ratio is the Earnings Yield.
Eg, if we invest in a company that
is trading at Rm1.2 per share and its Earnings Per Share (EPS) is 15 sen, the PE of the
Company is 8, earnings yield = 0.15/1.2 = 12.5%. Meaning it will take us 8
years to recover our Rm1.20 investment (don't forget we still hold the shares, at zero cost now), with the assumption that the company
continue to earn 15 sen per share.
Generally, the lower the PE, the
cheaper it appears. Please take note, it may also means that investment community
do not think the future prospect of the company is good ( most of the time, Mr
Market has priced in the company’s future prospect but at times, Mr Market can
be mad in pricing too – either unreasonably high or low). Hence even it is
trading at lower PE now, it may turn out not so later as the company may be in
a sunset industry and its earnings may be on down trend already or may consists of one off gain in earnings.
There are few PE variants commonly used:-
- Historical PE where we use the last FY earnings
- TTM(trailing twelve months’ results) PE where we use the latest 4 quarters results
- Prospective PE – try to use future earnings or growth guidance provided by company
- Some would just use the latest quarterly results and multiply by 4 to arrive at its prospective earnings and hence its PE ( This will only be reflective if the earnings are stable and not in sectors that are cyclical in nature).
Advantage of PE ratio as valuation metrics
- Simple and easy to understand
- Easily available
Limitation of PE ratio
- Time value of money not considered
- What about the growth prospects in future
- How to value loss making company which has no historical earnings
- Not easy to compare against different industries
- May have one off gain/(loss) in the earnings
How do we know at what PE is cheap or expensive?? Well, it
seems that the followings are used to compare companies :-
- Industry/Sector that it is in, what is the average PE
- Growth prospects
For instance, Technology
companies command higher PE as most believe this sector has higher growth rate,
Telco & consumers stocks seem to have higher PE than industrial, property
or plantation as they are viewed to be more stable and not too cyclical.
My personal view is that it
should not be used rigidly as businesses are changing where stable business may
not be so stable (eg offline retailing use to be stable until it is disrupted
by ecommerce, bank used to be stable and it may now be threatened by various
innovative fintech companies). I would place more emphasis on whether the
management can continue to innovate and be competitive all the time. Hence, in
my opinion, good companies with strong management should be accorded a higher
PE too.
Price Earnings Growth (PEG)
PEG = PE/ Growth %
The lower the PEG, is an
indication that the company is trading at “lower” valuation given its growth
prospect. The followings are used to illustrate how PEG can be used to overcome
one of the limitations of short term view of PE (please always bear in mind,
there is risk of over or underestimate the future growth that can cause us to
buy a stock that turn out to be overvalued/ undervalued)

Purely from PE comparison (without considering the cashflow
and financial position eg gearing level, cash in hand, no of shares, size of
the company, etc) we can conclude that:-
Company A vs Company B
Company B appears expensive (higher PE) now but it is a high
growth company, after 3 years, it will appear cheaper than Company A ( as shown
by lower PEG in B). However, the risk – can Company B sustain its growth??
Company A vs Company C
Company C appears better as it has lower PEG and 1 year
later, it appears cheaper than Company A and if the growth can
continue as projected, it will get cheaper and cheaper.
Company B vs Company C
Though both Companies have the same PEG, company C appears
cheaper in first 3 years as the high PE for Company B requires consistent high
growth (60% vs 20%) to catch up.
My own guideline is always going
for low to moderate PE with reasonable growth assumption as high PE (eg more
than 30 times in Company B) really required very high and consistent growth and
take longer for me to recover my investment. Obviously investors in high growth
technology (eg Amazon PE 184) will not agree with this and even some high tech
companies without profit for years (eg Tesla , loss making but with high
expectation that it will be very profitable in the future) command much higher
valuation than many other profitable companies. Yes, nothing is absolute in
investment and no metric is the perfect valuation tool as we are talking about
the uncertain future.
PEG ratio is useful to compare
companies with different growth prospects. To evaluate whether a growth company
deserves a higher PE, I always bear in mind that expectation of growth should
be based more on reasonable assumptions (eg is there any expansion plan, new
products launch, etc ) not just based on hope.
PE is a useful indicator but not
the ultimate or most reliable metric as there are other metrics (Discounted
Cash Flow, EV/EBITDA ) to measure the value of a company/business for company
that may have moderate PE ratio but ability to generate strong cashflow – eg companies
that may have invested heavily in the past and are now enjoying the fruits with
very little capital expenditure needed now.
I tend to agree with the popular
saying that valuation is more art than science, especially when it involves so
many aspects of the business – the quantitative as well as qualitative aspects.
It may look expensive to you but cheap to another person or vice versa but
eventually it may get closer to what most people think what is its fair value.
Let’s take a look at Superlon’s case,
Historical PE (based on FY 16) =3.59/0.21 = 17.1
TTM PE = 3.59/.265 = 13.5
PE based on earnings using latest quarterly results x4 =
3.59/ (4x 0.788) = 11.4
Prospective PE (FY18) = 3.59/.35 = 10.3
(assuming a 30% growth in profit
for FY18 based on TTM profit, I believe it is not too aggressive as profit
growth for the last 2 years were more than 50% and 2017 growth expected to be
at least 30% , in addition, the new warehouse and expansion in Vietnam strengthen
the growth prospect)
As investment is about the future
of the company, historical PE is definite and more reliable for company with
stable earnings and little growth. For growth company, prospective PE would be
a better measure (of course it involves the risk of over/under estimate the earnings
growth).
What is the “fair” price for Superlon??
I like to compare it with Wellcall, which is trading at TTM PE
of 23.
Is the expected growth rate excessive? Is it supported by
more solid assumptions?
Prospective PE of 10.3 is still attractive. I believe 30% growth assumption
for FY18 is achievable given the new warehouse would be fully operational (
MIDF projected growth of 10-20% in capacity for Superlon) and expansion in
Vietnam may contribute as well.
Its really your guess versus mine
but for now, I will continue to hold as based on prospective PE, it does not
seem overvalued and I am looking forward to the contribution from new warehouse
as well as from the Vietnam expansion. End of the day, management's capability to deliver results should be accorded a higher PE than comparing to industry's PE in general.
Thanks for this article that made to hold on to superlon.
