In previous
articles, the basic concepts of DCF valuation such as time value money and FCFF
were discussed (Read more here), and (Read more here).
This article will focus on basic concept of WACC and cost of equity,
which are essential to “discount” the future FCFF stream to present value.
Some
websites provide WACC and cost of equity for free, but the numbers provided by
each site are slightly different. This
article will guide you to compute the WACC and cost of equity yourself.
WACC is the
cost of capital to run a company, which include debt and equity. The formula of WACC is
where,
Debt = market value of debt (or book value of
debt)
Equity = market value of equity (market cap)
kd = Cost of Debt
ke = Cost of Equity
Again, math
is simple but getting the correct number to be inserted into the formula is not
straight forward. The following table
shows the source to obtain the numbers and the level of difficulty to get them.
(for simplicity, kd is estimated using this year interest expense divided by average of this year and last year total debt)
CAPM is the
most popular way to estimate cost of equity.
The formula of CAPM is
where,
Rf =
Risk Free Rate (or Fixed Deposit rate for retail investor)
β =
Beta (volatility of stock relative to overall market)
Rm =
Market return
(Rm – Rf) = Market Risk Premium
It is not
easy to compute Beta but there are a lot of tutorials available on web or
Youtube. Fortunately, many financial
websites are now publishing beta of company, but the issue is their numbers are
different from each other. This because each
source is using different time horizon to calculate beta. Some use 1-year, some use 3-year, and most of
them do not state the time horizon explicitly.
Generally, those who do not state the time horizon highly likely are
3-year beta.
Market
return, or more popular measure – “market risk premium” is also difficult to
estimate. Professor Damodaran from NYU
Stern maintains a page to provide market risk premium for various country but
only update occasionally for country outside US. However, Malaysia investors can roughly
estimate the market risk premium by using the implied ERP of S&P500 plus
the yield spread between US T-Bill and Malaysia T-Bill. Both data could be found in the Damodaran’s
page and Bank Negara Malaysia website.
It is time to go for a real world example. Again, we are
going to compute Top Glove WACC. The following table shows the
respective data required to calculate WACC as at 9pm 18 November 2020.
The
computed WACC is 9.80% (WACC = 7.4% if 3-Yr Beta is used), which is higher than the numbers reported by some
websites. The main reason is we are
using 1-Yr Beta (3-Yr Beta is around 0.8), which is highly volatile due to
recent spike in prices.
We have
covered three basic concepts of performing a DCF valuation, which are time
value money, FCFF, and WACC (and cost of equity). We will dive into the spreadsheet construction
in the next article to estimate the value of Top Glove.
