Value Investing

Let's use the Stock Screening process to build successful Value Investing strategies. As we'll find out, it's easy.

Investing Universe

Value Investing is well suited to Large Market Capitalizations which constitute the main universe. Here are some good starting points to fish for Value stocks:
  • Major Index membership (Large Cap): Dow Jones, S&P500, Russell1000...

  • Market Leaders: an enhanced Large Cap universe. James O'Shaughnessy used them in his Cornerstone Value strategy. Market Leaders have above average Market Cap, Revenue, Cash Flow, Shares outstanding.

  • Stock Ratings focusing on Quality, Leadership or Value are also good Investing Universes. An example would be Value Line Safety Rank.
Note: Zacks Investment Research suggests that Value Investors should not be shy using their Zacks Rank, a stock rating focusing on Growth/Momentum which may highlight smaller cap.

According to them, a good Zacks rank might be the catalyst for a Value stock to start performing. You may relax the ranking to include both Zacks rank 1 and 2. In this case, don't forget to increase the number of holdings when dealing with smaller Cap.

Primary Theme Go back to Top

Value investors look for stocks selling at an attractive price compared to 2 types of measure:
  • Valuation measure

    GroupValuation Measure
    Income StatementLow Price/Sales PS or PSR
    Low Price/Earnings PE or PER
    Cash Flow StatementLow Price/Cash-Flow PCF
    High Dividend Yield
    Balance SheetLow Price/Book-Value PBV


  • Intrinsic value estimate
    Value Investors screen for stocks selling at a Discount to intrinsic value: a theoretical stock price computed from future expected Earnings or Cash Flows.

    Several intrinsic value approaches exist and a growth estimate is required. Therefore, there may be wide variations in intrinsic value computations from different sources. Companies that have more predictable earnings would provide a more accurate computation.

Many academic studies have shown that simply screening with one valuation measure, such as low Price/Sales or low Price/Book-Value, provides superior performances over the long term.

Most of these studies assume that you’re buying a large number of value stocks (≥25). Although it is now possible to invest in a large number of stocks at low cost with a Stock Basket Account, some investors may not want or may not have access to such low cost Broker.

In order to bring the portfolio down to a lower number of stocks, further filtering is required.

A simple approach is to screen for stocks that pass through 2 valuation measures, for instance from 2 different groups.

Example: buy stocks that have low Price/Earnings ratio (Income Statement) and low Price/Book-Value ratio (Balance Sheet).

It is not recommended to screen with more than 2 valuation measures: there will be overlaps and you'll reach a point of diminishing returns where your screen will start to actually flash many real dogs.

Discount to Intrinsic value is seldom used in a Value screen, except if included in a Stock Rating. In fact, much less studies and backtesting have been performed with Discount to Intrinsic value because it is more complex to compute and it requires assumptions in growth rate. Thorough academic studies are therefore more difficult. Finally, few screeners provide a Discount to Intrinsic value measure.

Secondary theme Go back to Top

Quality is the main secondary theme used to increase the robustness of a Value Investment Strategy.

If the Investing universe used is not a major Index or a Stock Rating focusing on Quality, then it is recommended to add a Quality criterion in your screen.

Indeed, Value stocks are often those that have fallen out of favor: Slumping Industry, Profit Warning... Therefore, a Quality theme in the screen allows to filter the companies that are strong financially and have a higher chance to withstand a temporary setback.

Quality criteria include low Debt, Positive Cash Flow or Positive Earnings...

Ranking Go back to Top

Valuation ratios constitute the main ranking parameters, especially when none has been used in the screening.

Many simple strategies just use an Investing Universe and then rank stocks based on a Valuation ratio: Dogs Of the Dow is one such strategy.

Using Momentum (Relative Strength) in a Value screen ensures that you’re buying a Value Stock when the Market has started to realize its potential. This is especially important with smaller Caps that have not yet been discovered by the investment community.

This approach has been popularized by James O’Shaughnessy in What Works on Wall Street where he showed that Ranking Value screens with Relative Strength and buying top ones is among the best mechanical strategies.

Now, Momentum increases Volatility so add Relative Strength only if you can stomach higher risk.

Holding Periods Go back to Top

Value Investing requires longer holding periods as it can take time for the market to discover a stock’s true value. Benjamin Graham keeps his value stocks for up to 2 years, Warren Buffett forever.

In "Contrarian Investment Strategies: the next generation", David Dreman shows that Value Investing can provide outperformance with holding periods of 8 years. It means that you can Buy and Hold a Value portfolio for 8 years, it will still outperform the market.

Value screens should have holding periods ≥ 1 year.

Reciprocally, whatever your investing strategy, always include a valuation measure in any stock screening with holding period exceeding a year.

Value Investing characteristics Go back to Top

Value Screens often exhibit the following characteristics:
  • Best with Larger Market Capitalizations
  • Lower Volatility
  • Longer Holding periods: good for transaction costs and taxes,
  • Larger portion of gains from Dividends: may impact after Tax returns
  • Better downside protection in Bear Markets

Sample Mechanical Value Investing Screens Go back to Top

The following table summarizes the main criteria for building successful Value Investing strategies. In addition 2 popular simple value screens are shown: the Dogs of the Dow and James O'Shaughnessy's Reasonable Runaways (Value + Momentum).

As you can see, successful Value Investing is pretty simple.
