Roubaix Capital Outperforms With Small-Cap Stocks; here are their favorites
Roubaix Capital's flagship investment fund declined by 1.19% in the month of September. However, despite this negative monthly performance, the fund returned 15.6% for the year to the end of September, outperforming the S&P 500, which returned just 5.6% over the same period. Roubaix employs a fundamental long/short equity strategy focused on small and mid-cap Read More

The Reasoning Behind Return On Capital in the Magic Formula
The magic formula was introduced in the Little Book That Still Beats the Market written by Joel Greenblatt, and ranks companies based on two factors
- return on capital
- earnings yield
In this post we take at the first factor: return on capital.
This is what Greenblatt wrote in the little book:
The Magic Formula Version of Return on Capital
The formula used by Greenblatt is:
Greenblatt chose this version ratio rather than the common version of ROE or ROA for several reasons.
Why EBIT? The Reason for the Numerator
EBIT (or earnings before interest and taxes) is used in place of reported earnings because companies operate with different levels of debt and differing tax rates. This allows you to view and compare the operating earnings of different companies without the distortions arising from differences in tax rates and debt levels.
For each company, it is then possible to compare actual earnings from operations (EBIT) to the cost of the assets used to produce those earnings (tangible capital employed).
For purposes of the study and in the interest of simplicity, it is assumed that depreciation and amortization expense (noncash charges against earnings) were roughly equal to maintenance capital spending requirements (cash expenses not charged against earnings).
Assumed that EBITDA ? Maintenance Cap/Expenditures = EBIT.
The Reason Behind the Denominator
Here's a look at closer look at how and why the denominator was chosen.
Net Working Capital + Net Fixed Assets (or tangible capital employed) is used in place of total assets (used in an ROA calculation) or equity (used in an ROE calculation).
The idea here is to figure out how much capital is actually needed to conduct the company's business.
Net working capital is used because a company has to fund its receivables and inventory but does not have to lay out money for its payables, as these are effectively an interest-free loan (short-term interest-bearing debt is excluded from current liabilities for this calculation).
As a side note, in this calculation, excess cash not needed to run the business was excluded.
In addition to working capital requirements, a company must also fund the purchase of fixed assets necessary to conduct its business, such as real estate, plant, and equipment.
The depreciated net cost of these fixed assets is then added to the net working capital requirements already calculated to arrive at an estimate for tangible capital employed.
NOTE: Intangible assets, specifically goodwill, were excluded from the tangible capital employed calculations. Goodwill usually arises as a result of an acquisition of another company.
The cost of an acquisition in excess of the tangible assets acquired is usually assigned to a goodwill account. In order to conduct its future business, the acquiring company usually only has to replace tangible assets, such as plant and equipment.
Goodwill is a historical cost that does not have to be constantly replaced. Therefore, in most cases, return on tangible capital alone (excluding goodwill) will be a more accurate reflection of a business's return on capital going forward.
The ROE and ROA calculations used by many investment analysts are therefore often distorted by ignoring the difference between reported equity and assets and tangible equity and assets in addition to distortions due to differing tax rates and debt levels.
Return on Capital In Use: Comparing Coca-Cola, Pepsi & Dr Pepper
(note: the original article and numbers are from 2013 but the concepts and conclusions are the same)
With Greenblatt's formula I calculated the return on capital for three well-known companies.
I also added a breakdown to show the two drivers of return on capital
- EBIT-margin (Operating income / Revenues)
- Invested Capital (Net Fixed Assets + Net Working Capital) turnover.
|Amounts in millions.
Fiscal year 2013.
Source: Annual reports.
|Coca-Cola (KO)||PepsiCo. (PEP)||Dr Pepper Snapple Group (DPS)|
|Return on Capital||277.8%||58.5%||82.9%|
|Net Fixed Assets||14,967||18,575||1,173|
|Net Working Capital||(11,285)||(1,993)||89|
|Excess Cash (>5%)||14,778||6,357||N/A|
|Drivers of Return on Capital|
|× Invested Capital, turns||12.73||4.01||4.75|
|= Return on Capital||277.8%||58.5%||82,9%|
You can see why Coca Cola is the leader in the industry.
All three companies show great return on capital for fiscal year 2013 and if you look at the breakdown you can get deeper insight of how higher operating margin is driving the return on capital.
Try it out yourself for homework. It's not difficult. When performing competitor analysis, you'll be able to get deeper insight into which company is actually better.
I hope this helps you understand the true meaning behind Greenblatt's Return on Capital calculation and why it's used.
