After
much prevarication now it is time for me to dwell on my research
methodology. I want to use discounted cash flow (DCF) method to value
the stocks. It is a form of "fundamental analysis". This
form of analysis is distinct from "technical analysis" or
"charting" which looks at charts of prices and tries
to find trends to predict where the price will be going ahead.
Fundamental analysis claims greater depth of thinking since it looks
at fundamental factors that impact stock prices. In DCF, for
instance, various profit line items such as revenue, costs etc are
forecast in to the future and the resulting cash flows is discounted
back to the present to get the value.
So
I will use DCF. An important aspect of DCF valuation
is the forecasting. Since companies are considered going concerns,
that is their winding up is not considered, the cash flows from their
operations need to be forecast to an indefinite time in the
future, i.e., infinity. Since it does not make sense to engage in a
never ending process of predicting values of forecast variable for
each year, after a point the values are expected to stabilize and
follow a trend. The time horizon up to this point is called the
forecast horizon. The cash flows after this point, when discounted to
the end of the forecast horizon, add up to the terminal value. So the
value from DCF can be expressed as the sum of the
discounted value of the cash flows in the forecast period and the
discounted value of the terminal value.
For
forecasting I will either use simple methods like expecting
the CAGR (Cumulative Average Growth Rate) to continue in to
the future, expecting the last year's value to hold, or just manually
enter values, based on my hunch. For this I may refer to industry
news and research items to better inform my arbitrariness. In certain
cases I may defer to industry analyst's forecasts published
elsewhere. The variables that will be forecast include mainly
revenues and expenses, and they are expected not to change too
drastically, or, if they change, then to do so in a random manner
that would leave even the wise confounded. This is because the
companies analyzed are large and their business models
cannot be drastically altered with any great speed and if this is
accomplished then the consequences become unpredictable. You can't
turn a train around like you would a bicycle and if you do, it might
just end up derailed.
Since
I will be valuing equity, I can either calculate the future cash
flows to equity directly or I can calculate the cash flows to the
firm and subtract the debt from firm value thus calculated. So this
leads to the question what are cash flows to equity and cash
flows to firm. Which then begs the question what are equity and firm.
Well, a firm can be lots of things. For me it is an entity that the
published financial data (balance sheet, profit and loss statement
and cash flow statement) that I will refer to correspond to. Since I
want to focus on the Nifty, these would all be public
companies. Details of other forms of organizing the firm can be
obtained elsewhere.
A
firm requires capital to function and this is raised by two means:
equity and debt. Equity provides ownership and is more risky, since
there is a chance that it can be wiped out if the business tanks.
Debt is borrowed capital and is less risky since it is
legally required to be paid off at agreed intervals and has an
earlier claim on the firm’s assets if the company goes belly
up. But the pay-off from debt is fixed at the agreed rate of
interest while the equity can increase in value without bounds.
Once
a firm starts functioning it generates revenue and incurs costs.
Revenues come from sale of goods and services or profits from
investments. Costs are incurred in a variety of ways and the
classification of costs is an elaborate exercise that constitutes the
preliminaries of cost management. I excuse myself of that burden.
Broadly, the costs relate to making the goods and services, marketing
and selling them, and paying off relevant stakeholders such as
employees, debtors and the Government. What remains of the
revenues after costs have been deducted is the net profit of the
firm. This belongs to the shareholders, i.e., the owners of the
equity. But it is not this cash flow that is discounted to get the
equity value. Rather, a measure called free cash flow to
equity (FCFE) has been constructed to facilitate getting an
accurate picture of the cash flows that accrue to equity. This is
because the calculation of the net profit involves non-cash and
non-operating items which have to be accounted for before
understanding what is the cash flow that actually comes to the
shareholders. Since the starting point for my DCF analysis are
the financial statements, the equation for FCFE is the same as that
given by Wikipedia:
FCFE=Net
Income + Depreciation and Amortization - Capex - Change in Working
Capital + Net Borrowing
Depreciation
and amortization are added back because they are a non-cash change in
the value of some capital goods, investment in which was accounted
for in some previous year in a lump-sum manner as the current capex
is being accounted for in the FCFE equation in the current period. So
is the case with working capital since an increase in the working
capital lowers the cash available to the shareholders for the present
but would lead to more revenues in the future (hopefully). Net
borrowing that does not go into capex or change in working capital is
a cash flow available to the equity holders so it is included in the
FCFE equation.
To
discount the FCFEs of various years back to the present I use the
equity cost of capital calculated from the CAPM equation,
which is very popular and widely used. Details of the choices
regarding the CAPM parameters, for instance the period for
calculation of various parameters of the CAPM, are rather pedantic
and I ignore them. My forecast horizon too would be ad hoc usually
somewhere between 5 and 10 years. Terminal growth rate too would be
chosen on a case to case basis with appropriate justification
provided in each case.
This
should sum up adequately my modus operandi with respect to the
valuation procedure. Hence I conclude this post here.
