Qi Value Investment Strategy

Qi Value Investment Strategy


When we first tested the Qi Value investment strategy (and I started using it in my own portfolio) I honestly did not think it would work this well. 


22 year return +1223%

Over the nearly 22 years from May 2001 to December 2022 across markets worldwide it returned an astounding 1223.0%! This is more than 8.3 times the 148.1% the market (MSCI World Index) returned over the same period. 

Before I tell you exactly how to implement this strategy in your portfolio first some background information.


We like composite ratios

We are big fans of combining a different ratios to find undervalued companies. This helps you to find companies that are undervalued from different points of view, for example based on earnings and cash flow. 

The first such indicator I wrote to you about was the Value Composite One (included in the stock screener) developed by James O'Shaughnessy.


But it has a problem

The problem with the Value Composite One indicator is that it includes the Price to Book ratio. 

We have nothing against you using the price to book ratio to find undervalued companies (it works best after a crash), the problem is it underperforms the market for long periods.

You can read more about the underperformance here: Be careful of this time tested value ratio.


To solve the problem

To solve this problem we developed a composite value indicator, which we called Qi Value

Not only does it exclude the Price to Book ratio, it also includes all the best valuation ratios we have tested up till now, including the work from the research paper Quantitative Value Investing in Europe: What Works for Achieving Alpha.

Qi Value ranks the whole universe of companies (around 22,000) in the stock screener using four valuation ratios. It lets you find the most undervalued companies from different points of view.



How is Qi Value calculated?

Q.i. Value is calculated with the following ratios:


Calculated as: Earnings before interest, taxes, depreciation and amortisation (EBITDA) / Enterprise Value

Earnings Yield

Equals Operating Income or earnings before interest and taxes (EBIT) / Enterprise Value (Read more about earnings yield here: A simple ratio beats the world’s best value funds)

FCF Yield

FCF (Free cash flow) Yield is calculated as Free Cash Flow / Enterprise Value – here free cash flow is equal to cash from operations minus capital expenditure

Liquidity (Q.i.)   

Liquidity (Q.i) is calculated as Adjusted Profits / Yearly trading value.

It thus gives you an indication of how high a company’s yearly traded value per share is compared to its profits. A high value means low traded value compared to profits and thus a larger chance of the company’s shares being miss-priced.

In the following article can read about our back test of Qi Liquidity: This overlooked ratio, large funds and hedge funds can’t use, gives you higher returns


Results of the back test

In the first half of 2015 we tested Qi Value against six other investment strategies as well as the market over the 14 year period from April 2001 to February 2015.

The following table summarises the results:

We tested the Qi Value indicator against:

  • Earnings Yield (EY) = Earnings Before Earnings and Taxes (EBIT) / Enterprise Value
  • Price to Free Cash Flow (P/FCF)
  • Price to Earnings (PE)
  • Earnings before interest, taxes, depreciation and amortisation (EBITDA) / Enterprise value
  • Price to Sales (PS)
  • Price to Book (BP)

Qi Value is a lot better

As you can see Qi Value performed better than all ratios, only the average return of the Price to Sales ratio was higher. 

Apart from that the Qi Value had a:

  • The highest total return +477.6%
  • The highest compound annual growth rate over the 14 year period
  • The lowest standard deviation which means Qi Value returns were not as volatile as the other ratios
  • The highest Sharpe ratio (higher is better) which means it would have given you higher risk adjusted returns. Here is the Sharpe ratio definition.


What about 2016 to 2022?

We have continued tracking the results of the Qi Value to make sure the back test remains valid. 

Here are the updated results:

CAGR (Compound Annual Growth Rate)


As you can see Qi Value continues to do well. Not the highest returns but very consistent high returns which gives it the highest total return and compound annual growth rate.


8.3 times better than the market

Qi Value’s total return of +1223.0% was the highest, and was 8.3 times that of the market and 210.3% better than Price to Book the second best performing strategy.


Not all strategies tested again

Just in case you were wondering - we are not selectively showing the results of other strategies so that Qi Value looks best we do not test all the strategies all the time as it is a lot of work.

The Piotroski F-Score is a great indicator you can use to select good quality companies – I use it all the time with the screens I use.

Market leaders (large companies on steroids)

If you prefer investing in large companies Market Leaders is a great universe to look for investment ideas.

The name Market Leaders come from the book What Works On Wall Street where James O'Shaughnessy tested an investment strategy of only investing in market leading companies which resulted in market beating performance. 

James defined Market Leaders as Non-utility companies with larger than average:

  • Market value
  • Number of shares outstanding
  • Free Cash flow and
  • Sales above 1.5 times the average of the universe

The best valuation ratio you can use

From all the above research I am sure you will agree that Qi Value is a great indicator because it finds undervalued companies using a number of proven ratios combined into a single value. 

Its results speak for themselves, higher returns with lower volatility, something I am sure you are also interested in.
