The King Of The Jungle Ready To Pounce

Screening For Winners On Porter’s 3x Filter

Each week, here at Porter & Co., we apply our financial brainpower to uncover the most compelling, highest-upside investment ideas. And with this complimentary issue of the Daily Journal, we open up our spreadsheets to show you how we do it.

An important tool in our analytical toolbox is our stock screens, where we apply a list of criteria – relating to different financial, accounting, and performance parameters – to sift through the 3,000+ publicly traded stocks on U.S. markets. That’s how we identify the tiny fraction of U.S.-listed stocks that offer the best opportunities for creating huge returns.

We often use the results from these screens as a starting point for more in-depth analysis for possible inclusion in the Complete Investor portfolio.

This week, we’re revisiting a popular stock-filtering tool we call Porter’s 3x Stock Screen. Over the last 25 years, buying an equally-weighted basket of stocks generated from this screen has tripled the return over the overall stock market (the S&P 500). Below we also show the names of significant stocks hitting 52-week highs and 52-week lows – a helpful list that we use to guide our analysis. 

For Partner Pass members, in the Saturday Stock Screen, we’ll occasionally (like today) highlight an opportunity that we found from the screen that appears particularly compelling – not as an official recommendation, but as a stock that’s on our radar.

Porter’s 3x Stock Screen 

The 3x Screen was inspired by Porter himself, who challenged the Complete Investor analyst team to create a filtering tool to find companies with high capital efficiency, steady revenue growth, and that trade at reasonable valuations… and to backtest the results to ensure the screening criteria selected stocks that generated market-beating gains over time. 

One of the best screens we found in this search applies the following criteria:

  1. Return on assets (“ROA”) of at least 15% over the previous five years 
  2. Return on equity (“ROE”) of at least 20% over the previous five years
  3. Free cash flow (“FCF”) margins of at least 10% over the previous five years
  4. Sales growth of at least 5% over the previous five years
  5. P/E ratio of 25 or below 
  6. Market capitalization of at least $300 million 

We performed a backtest of these criteria on a hypothetical portfolio that held an equal dollar amount of each stock on this list, and rebalanced the portfolio each quarter – to add new stocks that met the criteria, and sell stocks that no longer did. The chart below shows that the stocks selected by this screen delivered a total return of 1,783% over the last 25 years versus a 537% return in the S&P 500, for outperformance of 3.3x. 

As of Thursday’s close, this screen produced the 29 stocks shown in the table below. We have displayed each of the criteria noted above along with each company and ticker symbol, as well as each stock’s beta (a measure of volatility versus the overall market). Note that beta is not used in the screening criteria, but rather to provide a reference point for noting the volatility of the stocks on the list.

Highs And Lows 

Each week, we also monitor any stocks in the market making new 52-week highs. We do this because any stock on its way to generating 2x, 3x, or 10x returns will spend a lot of time making new 52-week highs along the way. Thus, the new 52-week-high list provides an opportunity to flag these potential high performers before they really break out, with a particular emphasis on lower-profile, less widely-followed stocks that might have otherwise gone unnoticed.

Notable stocks making a new 52-week high this week: 

  • Alcoa (AA)
  • Ameris Bancorp (ABCB)
  • Arcosa (ACA)
  • American Eagle Outfitters (AEO)
  • Ally Financial (AALY)

In this advertisement from our friends at Paradigm Press, former CIA insider and best-selling author Jim Rickards believes a $150 trillion mineral boom is about to begin.

Jim recorded this interview containing all the details, including how you can sign up to receive his research on The American Birthright: Phase II, including 3 small stocks that skyrocket if he’s right.

Keep in mind, we only accept advertising from publishers we know to offer well-researched ideas vetted by a legal team, excellent customer service, and reasonable refund policies. Paradigm Press is one such partner. We do not, however, under any circumstances make any representations about its investment ideas or strategies, nor will we warrant them as equal to our own. We do recognize that the markets can be tempestuous and, at times, ideas that we may not endorse prove valuable.


We also monitor stocks on the new 52-week-low list. In many cases, the names on this list are there for good reason – the market is often correctly pricing in weak fundamentals. However, once in a while, a great business with excellent long-term prospects finds itself on this list due to a temporary setback. This can create the rare opportunity to buy top-shelf merchandise at bargain-basement prices. 

Notable stocks making a new 52-week low last week: 

  • Doximity (DOCS)
  • Rezolute (RLZT)
  • Kosmos Energy (KOS)
  • Oxford Industries (OXM)
  • Invitation Homes (INVH)
  • Mondelez International (MDLZ)
  • T-Mobile U.S. (TMUS)
  • The Trade Desk (TTD)
  • Venture Global (VG)
  • Zoetis (ZTS)

FOR PARTNERS ONLY

This Lion Among Cats Will Soon Roar The Loudest

This week’s Saturday Selection comes off Porter’s 3X Screen. It’s a global leader in a specialized corner of healthcare that has compounded at roughly 11% annually since going public a little more than a decade ago. Yet despite this track record, shares are down more than 25% year-to-date.

This is a business defined by scientific rigor, operational discipline, and a portfolio of trusted products that support patient health and resilient food systems. Recently, however, macro softness and rising competition have dulled investor enthusiasm, leaving the stock overlooked at a moment when its long-term prospects remain bright.

The company holds one of the deepest pipelines in all of healthcare, with at least one blockbuster drug expected every year for the next four years. With the stock now trading near its lowest valuation in years, this is a compelling setup for a proven compounder.
