The O-S Checklist Approach
We develop a simple approach for making stock selection decisions. The philosophical underpinning of the Otuteye-Siddiquee (O-S) checklist approach is that it is possible to create a simple value investing decision making tool using criteria based on earnings potential, financial stability, and fair valuation. Furthermore, application of this tool will help the user to develop a consistent and disciplined approach to value investing decision making that will yield very satisfactory results.
We hypothesize that portfolios that are created from this approach will yield returns above the market average. The market return is the average returns from two sets of portfolios: those with above average returns and those with below average returns. We reason that if the stock selection criteria of the O-S approach are carefully applied, the resulting portfolios should be among the group with above average returns.
The way the O-S approach works is that prospective stocks that an investor is interested in will be subjected to a set of screening criteria. At the end, the investor will make one of three decisions: (i) reject the stock, (ii) put it on a watch list, or (iii) buy it. If a company is not investment worthy then the decision to reject it will be made immediately at the stage that the screening criteria point to that. A company will be put on the watch list if all the financial metrics are sound as revealed by the screening criteria but the stock price fails to meet the margin of safety criterion. Failing the margin of safety criterion means either the stock is selling above the intrinsic value or there is not sufficient margin of safety to classify it as a safe investment. A recommendation to buy a stock means that all the financial metrics are sound and the “price is right” (i.e. it is selling at a price that gives a good margin safety, as explained below).
There are two main parts to executing the approach: the preliminary stock selection criteria (referred to as the “5-Minute QuickScan”) and the full set of value investing criteria. The two parts are presented in Tables 1 and 2 respectively.
The 5-Minute QuickScan is a preliminary screening tool to determine if a company is worth taking through the entire screening criteria. It is essentially a device for narrowing down the number and types of companies that we will process through the full set of value investing screening criteria. Needless to say, an investor is only interested in good quality stocks. The 5-Minute QuickScan is the tool by which we focus our analysis only on companies that meet some minimum quality standards.
Table 1: Preliminary Stock Screening Criteria (The “5-Minute QuickScan” Screening Criteria)

Sl. No |
Criterion/ Question |
Decision Rule |
Rationale |
| 1 | Is the company listed on the OTC or on Pink sheet? Check whether the company’s ticker symbol has a .OB (NASDAQ bulletin board stock) or .PK (pink sheet) extension | Reject if the ticker has either .OB or .PK extension. | Information about .OB or .PK shares tends not to be up to date or always reliable. Although .OB companies have to file regular forms with the SEC, they are still not as safe as stocks listed on the major exchanges. |
| 2 | Is the company’s market capitalization below $500 million? | Include only companies with market cap > $500 million | The original intent of setting up this approach is to design a system that even investment novices can use and not lose money. For that clientele we felt it advisable to limit them to well established companies and this criterion increases the chances of that. |
| 3 | Recent IPO | Reject if the company does not have at least 5 years of public trading data. | Same reason as criterion # 2 – to limit the search to relatively well established companies with a reasonable (minimum 5 years) public trading history. |
| 4 | 3 to 5 years of positive EBIT? | Include only companies with positive operating profit for at least 3 years but preferably 5 years or more. | A critical indicator of future profitability is a track record of past profitability. Operating profit is regarded as a sign that this company can sustain itself through its business operation and also an indicator that it has been operating a viable business model. |
| 5 | 3 to 5 years of Cash Flow from Operating Activities? | Include only companies with positive cash flow from operating activities for at least 3 years but preferably 5 years or more. | This shows that the company is able to end up with positive cash flow of its own. Rationale similar to criterion # 4. |
| 6 | 5 years of ROE >10% | Accept only companies with at least 3 continuous years of ROE > 10%. If one of the past three years has ROE < 10% then look for 3 years out of the past 5 years. | ROE is an indicator of profitability and a 3 to 5-year track record is an indicator that profitability has been sustained in the past. |
| 7 | 5 years of Debt/Equity ratio < 1 | Accept only companies that meet that condition. | The goal is to limit the set to low leverage companies. We prefer companies with zero debt. |
| 9 | Tangible Book Value > 0 for the past 3 years. | Accept only companies that meet the condition. | While companies with good business models and sustainable competitive advantage can have negative net tangible value, analysis of such companies might be beyond the scope of beginners who are part of the user group for whom this approach is designed. |
Companies that fulfill all these preliminary screening criteria will now be subjected to the full set of value investing criteria in Table 2. There is one point we need to make specifically about criterion number 2 in the 5-Minute QuickScan: that the market capitalization must be greater than $500 million. The O-S approach is designed with what Benjamin Graham (1949) calls the “defensive investor” in mind. Specifically, Benjamin Graham’s (1949) recommendation to the defensive investor is that “each company selected should be large, prominent, and conservatively financed.” (p. 65). Limiting our set to companies with market capitalization greater than $500 million satisfies the condition of excluding small companies.

| Screening Criterion # 2A: Earnings Strength, Earnings Stability and Moat Indicators | ||
|
Sl. No |
Financial Ratio or Value Indicator |
Decision Rule |
|
1 |
Return on Invested Capital (ROIC) | ROIC must be at least 10% in each of the past five years. |
|
2 |
Equity Growth Rate | The annual compounded equity growth rate (measured by the rate of growth of Book Value per Share) must be at least 10% for the past 5 years. |
|
3 |
Rate of Growth of Earnings per Share (EPS) | The annual compounded EPS growth rate must be at least 10% for the past 5 years. |
|
4 |
Sales Growth Rate | The annual compounded rate of growth of sales must be at least 10%. |
|
5 |
Operating Cash Flow (OCF) Growth Rate | The annual compounded rate of growth for OCF must be at least 10%. |
|
6 |
Free Cash Flow (FCF) Growth Rate | The annual compounded rate of growth for both FCF must be at least 10%. |
|
7 |
Gross Margin | A gross margin greater than 40% is classified as an indicator of durable competitive advantage. |
|
8 |
Operating Margin | First we find the average operating margin for the industry or a core group of competitors. And then we look at the company’s operating margin, which must be above the average of the industry or its competitors. |
|
9 |
Net Margin | Net margin greater than 20% is considered a sign of durable competitive advantage and net margin less than 10% is interpreted as the company being in a highly competitive environment. |
|
10 |
Free Cash Flow (FCF) Margin | FCF margin greater than 10% is considered a sign of durable competitive advantage. |
| Screening Criterion # 2B: Financial Strength and Financial Stability | ||
|
Screening Criterion # 2B Part 1: Short-Term Financial Health |
||
| 11 | Current Ratio | Current ratio has to be at least 2. |
| 12 | Quick Ratio | Quick Ratio has to be at least 1.5 |
| 13 | Interest Coverage Ratio | Interest coverage ratio has to be at least 5. |
| 14 | Operating Cash Flow Ratio (OCF) | OCF ratio has to be at least 1. |
|
Screening Criterion # 2B Part 2: Long-Term Financial Health |
||
| 15 | Leverage Ratio | Leverage ratio (measured by Debt to Total Assets) has to be less than 0.5 except utilities for which leverage ratio equal to or less than 1.0 is acceptable. |
| 16 | Debt to Equity Ratio | Debt-Equity ratio has to be less than 1. |
| 17 | Long-Term Debt to Operating Cash Flow Ratio | This ratio is used to measure how long it will take to pay off long-term debt using OCF and it has to be 3 years or less. |
| Screening Criterion # 3: Susceptibility to Bankruptcy | ||
| 18 | Piotroski F-Score[ii] | Companies are accepted if the F-Score is 8 or 9 and they are rejected if the F score is less than or equal to 2. However, for companies with F score between 3 and 7, the decision to accept or reject is more subjective and the overall profile of the company in light of the other ratios is considered in arriving at a decision. |
| 19 | Altman Z-Score | A company with Z score less than 1.8 is rejected. A Z-score of 3 or higher is accepted. For companies with Z scores between 1.8 and 3, the entire profile of the company is considered before a final “accept” or “reject” decision is made. |
| Screening Criterion # 4: Company Valuation and Margin of Safety | ||
| 20 | Margin of Safety = (Intrinsic Value – Price)/Intrinsic Value | Margin of Safety must be at least 20%.(Intrinsic Value is estimated by two methods: the P/E ratio approach and Discounted Free Cash Flow approach) |
| Final Stock Selection Decision
If a stock meets all the benchmarks of Steps 1 to 19 then it is classified as “accepted” for inclusion in the portfolio. If in addition to fulfilling the requirements for Steps 1 to 19, the company also has a margin of safety of at least 20% then it will be recommended for purchase. Essentially, criteria 1 to 19 answer the question: is this a good company? And criterion 20 answers the question: is it a good time to buy the stock?Sometimes the intrinsic value based on P/E ratio valuation method may yield an acceptable margin of safety whereas the Discounted Free Cash Flow method does not or vice versa. In those cases, we make the decision based on the overall profile of the company. If all other indicators are very good then the company may be included in the “buy” portfolio. But if the other indicators barely make it past the acceptable standards then it will be put on the watch list. |

[i] It is obvious to see how these criteria make common sense to an investor who is looking for good quality companies. We arrived at them from an amalgamation of various stock selection criteria alluded in writings and interviews of various value investors including Benjamin Graham, Warren Buffett, Walter Schloss, Joel Greenblatt, etc.
