When evaluating high-risk long-term investments, it is essential to consider a wide range of factors. These investments, by their nature, have a higher potential for return, but they also carry the risk of significant losses. Whether you are looking at startups, emerging markets, or speculative assets, understanding how to assess their value can make the difference between success and failure. In this article, I’ll take you through the methods I use to value high-risk long-term investments, along with examples and calculations where applicable.

Understanding High-Risk Long-Term Investments
High-risk long-term investments are those where the investor takes on a considerable amount of uncertainty in exchange for the potential of high returns over a long period. These might include investments in startups, new technologies, or companies in volatile industries. Such investments often have unpredictable cash flows, unproven business models, or high levels of competition, making them more difficult to value.
1. Discounted Cash Flow (DCF) Analysis
One of the most widely used methods for valuing investments is Discounted Cash Flow (DCF) analysis. The idea behind DCF is simple: determine the future cash flows of an investment, and then discount them back to the present value using a discount rate that reflects the risk associated with those future cash flows.
The formula for DCF is:DCF=CF1(1+r)1+CF2(1+r)2+⋯+CFn(1+r)nDCF = \frac{CF_1}{(1+r)^1} + \frac{CF_2}{(1+r)^2} + \cdots + \frac{CF_n}{(1+r)^n}DCF=(1+r)1CF1+(1+r)2CF2+⋯+(1+r)nCFn
Where:
- CF1,CF2,…,CFnCF_1, CF_2, \dots, CF_nCF1,CF2,…,CFn represent the expected cash flows in future years.
- rrr is the discount rate, which reflects the investment’s risk.
- nnn is the number of years.
Example
Suppose a startup is expected to generate the following cash flows over the next 5 years:
| Year | Cash Flow (in USD) |
|---|---|
| 1 | 500,000 |
| 2 | 700,000 |
| 3 | 900,000 |
| 4 | 1,200,000 |
| 5 | 1,500,000 |
I’ll assume a discount rate of 15% to account for the high risk of the startup.
The DCF for this investment would be:DCF=500,000(1+0.15)1+700,000(1+0.15)2+900,000(1+0.15)3+1,200,000(1+0.15)4+1,500,000(1+0.15)5DCF = \frac{500,000}{(1+0.15)^1} + \frac{700,000}{(1+0.15)^2} + \frac{900,000}{(1+0.15)^3} + \frac{1,200,000}{(1+0.15)^4} + \frac{1,500,000}{(1+0.15)^5}DCF=(1+0.15)1500,000+(1+0.15)2700,000+(1+0.15)3900,000+(1+0.15)41,200,000+(1+0.15)51,500,000
Breaking it down:DCF=500,0001.15+700,0001.3225+900,0001.5209+1,200,0001.7490+1,500,0002.0114DCF = \frac{500,000}{1.15} + \frac{700,000}{1.3225} + \frac{900,000}{1.5209} + \frac{1,200,000}{1.7490} + \frac{1,500,000}{2.0114}DCF=1.15500,000+1.3225700,000+1.5209900,000+1.74901,200,000+2.01141,500,000 DCF=434,783+529,411+591,802+686,275+745,775DCF = 434,783 + 529,411 + 591,802 + 686,275 + 745,775DCF=434,783+529,411+591,802+686,275+745,775 DCF=2,987,046DCF = 2,987,046DCF=2,987,046
The present value of the future cash flows is approximately $2.99 million. This is the amount I would be willing to pay today for the startup based on my expectations of its future performance.
Limitations of DCF
While DCF is a useful tool, it’s not foolproof. The method relies heavily on projections of future cash flows, which can be very uncertain for high-risk investments. A small change in the assumptions about growth rates or discount rates can lead to significantly different valuations. Furthermore, for long-term investments, the discount rate might not fully capture the uncertainty and risk involved.
2. Risk-Adjusted Return on Investment (RAROI)
Another important method I use is calculating the Risk-Adjusted Return on Investment (RAROI). This method helps to measure the return on an investment after adjusting for its level of risk. I like to use it to compare different high-risk investment opportunities.
The formula for RAROI is:RAROI=ExpectedReturn−Risk−FreeRateStandardDeviationofReturnRAROI = \frac{Expected Return – Risk-Free Rate}{Standard Deviation of Return}RAROI=StandardDeviationofReturnExpectedReturn−Risk−FreeRate
Where:
- The expected return is the average return an investment is anticipated to generate.
- The risk-free rate is the return on a virtually risk-free investment (e.g., U.S. government bonds).
- The standard deviation of return is a measure of the investment’s volatility.
Example
Suppose I am considering two investments:
| Investment | Expected Return (%) | Risk-Free Rate (%) | Standard Deviation of Return (%) |
|---|---|---|---|
| A | 20 | 3 | 10 |
| B | 25 | 3 | 15 |
For Investment A:RAROIA=20−310=1710=1.7RAROI_A = \frac{20 – 3}{10} = \frac{17}{10} = 1.7RAROIA=1020−3=1017=1.7
For Investment B:RAROIB=25−315=2215=1.47RAROI_B = \frac{25 – 3}{15} = \frac{22}{15} = 1.47RAROIB=1525−3=1522=1.47
While Investment B has a higher expected return, Investment A has a higher risk-adjusted return. This means Investment A, despite its lower expected return, offers a better return for the level of risk it involves.
Limitations of RAROI
RAROI is useful, but it doesn’t account for factors such as market conditions, company-specific risks, or other qualitative aspects that might affect an investment. It’s important to use RAROI as one of several tools rather than relying on it in isolation.
3. Comparable Company Analysis (CCA)
When valuing high-risk long-term investments, especially startups or businesses in emerging industries, I often turn to Comparable Company Analysis (CCA). This method involves looking at similar companies that have publicly available data and comparing key metrics such as revenue, earnings, and growth potential.
The key multiples I use in CCA include:
- Price-to-Earnings (P/E) ratio
- Price-to-Sales (P/S) ratio
- Enterprise Value-to-EBITDA (EV/EBITDA) ratio
Example
Let’s say I’m considering an investment in a tech startup. I look at three comparable public companies:
| Company | Revenue (in USD) | Market Cap (in USD) | P/E Ratio | EV/EBITDA Ratio |
|---|---|---|---|---|
| A | 100 million | 1 billion | 25 | 15 |
| B | 150 million | 1.5 billion | 30 | 18 |
| C | 120 million | 1.2 billion | 27 | 16 |
Let’s say the startup I’m considering has projected revenue of $110 million. I would calculate its potential market value based on these multiples.
For P/E ratio, I could apply the average P/E ratio of the comparable companies, which is:Average P/E=25+30+273=27.33\text{Average P/E} = \frac{25 + 30 + 27}{3} = 27.33Average P/E=325+30+27=27.33
If I assume the startup will eventually generate $10 million in earnings, its potential market cap could be:MarketCap=10×27.33=273.3 million USDMarket Cap = 10 \times 27.33 = 273.3 \text{ million USD}MarketCap=10×27.33=273.3 million USD
Similarly, I could use other multiples like EV/EBITDA for further validation of the startup’s value.
Limitations of CCA
While CCA provides a good benchmark, it assumes that the comparable companies are similar in all respects, which may not always be the case. High-risk investments, particularly in new or speculative sectors, may have fewer comparable companies, which limits the usefulness of this method.
4. Option Pricing Models
For some high-risk investments, particularly in early-stage companies or those with uncertain future cash flows, I turn to option pricing models such as the Black-Scholes model or real options analysis. These models are particularly useful when I’m evaluating investments that have a lot of uncertainty and the potential for significant upside.
Real options analysis, in particular, treats the investment as an option to invest more money in the future if certain conditions are met. This is useful in industries like biotechnology, where the outcome of research and development efforts is uncertain.
Example
If I am investing in a biotech company that has an option to expand into a new market in two years, the value of that option can be calculated using the Black-Scholes model, which takes into account the volatility of the stock price, the risk-free rate, and the time to expiration.
While these models are powerful, they are also complex and require a solid understanding of financial mathematics.
5. Sensitivity Analysis
Given the uncertainty and volatility inherent in high-risk investments, I often perform sensitivity analysis to understand how changes in key assumptions affect the value of an investment. This method involves tweaking key variables—such as discount rates, growth rates, or operating costs—and examining the effect on the investment’s value.
Example
In the DCF model I discussed earlier, I can run a sensitivity analysis by changing the discount rate or cash flow projections. For instance, I could see how the DCF changes if the discount rate increases from 15% to 18%.
| Discount Rate | DCF (in USD) |
|---|---|
| 15% | 2,987,046 |
| 16% | 2,742,631 |
| 17% | 2,510,065 |
| 18% | 2,288,699 |
This analysis helps me understand the range of possible outcomes and make more informed decisions.
Conclusion
Valuing high-risk long-term investments requires a blend of quantitative methods and qualitative judgment. DCF provides a solid starting point, but it’s essential to complement it with risk-adjusted return metrics, comparable company analysis, and sometimes option pricing models. Sensitivity analysis further refines my understanding of the risks and potential rewards. Ultimately, the goal is not just to calculate the value of an investment, but to ensure I have a well-rounded understanding of the investment’s risk profile and its potential for future growth.
