• The projected fair value for Shanghai Tunnel Engineering is CN¥9.72 based on 2 Stage Free Cash Flow to Equity
• Current share price of CN¥7.00 suggests Shanghai Tunnel Engineering is potentially 28% undervalued
• Analyst price target for 600820 is CN¥9.52 which is 2.1% below our fair value estimate

Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Shanghai Tunnel Engineering Co., Ltd. (SHSE:600820) as an investment opportunity by taking the expected future cash flows and discounting them to their present value. One way to achieve this is by employing the Discounted Cash Flow (DCF) model. It may sound complicated, but actually it is quite simple!

Remember though, that there are many ways to estimate a company's value, and a DCF is just one method. For those who are keen learners of equity analysis, the Simply Wall St analysis model here may be something of interest to you.

Is Shanghai Tunnel Engineering Fairly Valued?

We're using the 2-stage growth model, which simply means we take in account two stages of company's growth. In the initial period the company may have a higher growth rate and the second stage is usually assumed to have a stable growth rate. In the first stage we need to estimate the cash flows to the business over the next ten years. Seeing as no analyst estimates of free cash flow are available to us, we have extrapolate the previous free cash flow (FCF) from the company's last reported value. We assume companies with shrinking free cash flow will slow their rate of shrinkage, and that companies with growing free cash flow will see their growth rate slow, over this period. We do this to reflect that growth tends to slow more in the early years than it does in later years.

A DCF is all about the idea that a dollar in the future is less valuable than a dollar today, so we need to discount the sum of these future cash flows to arrive at a present value estimate:

10-year free cash flow (FCF) estimate

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = CN¥18b

The second stage is also known as Terminal Value, this is the business's cash flow after the first stage. The Gordon Growth formula is used to calculate Terminal Value at a future annual growth rate equal to the 5-year average of the 10-year government bond yield of 2.8%. We discount the terminal cash flows to today's value at a cost of equity of 12%.

Terminal Value (TV)= FCF2034 × (1 + g) ÷ (r – g) = CN¥3.6b× (1 + 2.8%) ÷ (12%– 2.8%) = CN¥39b

Present Value of Terminal Value (PVTV)= TV / (1 + r)10= CN¥39b÷ ( 1 + 12%)10= CN¥12b

The total value is the sum of cash flows for the next ten years plus the discounted terminal value, which results in the Total Equity Value, which in this case is CN¥31b. To get the intrinsic value per share, we divide this by the total number of shares outstanding. Compared to the current share price of CN¥7.0, the company appears a touch undervalued at a 28% discount to where the stock price trades currently. Valuations are imprecise instruments though, rather like a telescope - move a few degrees and end up in a different galaxy. Do keep this in mind.

Important Assumptions

Now the most important inputs to a discounted cash flow are the discount rate, and of course, the actual cash flows. Part of investing is coming up with your own evaluation of a company's future performance, so try the calculation yourself and check your own assumptions. The DCF also does not consider the possible cyclicality of an industry, or a company's future capital requirements, so it does not give a full picture of a company's potential performance. Given that we are looking at Shanghai Tunnel Engineering as potential shareholders, the cost of equity is used as the discount rate, rather than the cost of capital (or weighted average cost of capital, WACC) which accounts for debt. In this calculation we've used 12%, which is based on a levered beta of 1.885. Beta is a measure of a stock's volatility, compared to the market as a whole. We get our beta from the industry average beta of globally comparable companies, with an imposed limit between 0.8 and 2.0, which is a reasonable range for a stable business.

SWOT Analysis for Shanghai Tunnel Engineering

Moving On:

Whilst important, the DCF calculation shouldn't be the only metric you look at when researching a company. The DCF model is not a perfect stock valuation tool. Instead the best use for a DCF model is to test certain assumptions and theories to see if they would lead to the company being undervalued or overvalued. For instance, if the terminal value growth rate is adjusted slightly, it can dramatically alter the overall result. Can we work out why the company is trading at a discount to intrinsic value? For Shanghai Tunnel Engineering, we've put together three further aspects you should further research:

1. Risks: For example, we've discovered 2 warning signs for Shanghai Tunnel Engineering (1 is a bit concerning!) that you should be aware of before investing here.
