The Bargain Hunter’s Munger Screen

Market Turbulence Creates Target-Rich Environment For Good Buys

The recent decline in the overall market has created a growing list of high-quality businesses trading at discounted valuations. 

In today’s Saturday Stock Screen, we’re taking a look at the latest list of potential opportunities popping up on our radar. 

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

An important tool in our analytical toolbox is our stock screens, in which 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’re able to identify the tiny fraction of the universe of U.S.-listed stocks that offer the best opportunities for making money.

We often use the results from these screens as a starting point for more in-depth analysis for possible inclusion in The Big Secret On Wall Street portfolio or any of our other portfolios.

For Partner Pass members, we’ll sometimes highlight an opportunity from the screen, or elsewhere, that appears particularly compelling (see below) – not as an official recommendation, but as a stock that’s on our radar.

This screen is inspired by the late Charlie Munger, Warren Buffett’s partner, who once described a dead-simple strategy for beating the market:

If all you ever did was buy high-quality stocks on the 200-week moving average, you would beat the S&P 500 by a large margin over time. The problem is, few human beings have that kind of discipline.” 

Our Modified Munger screen applies the following criteria, based on this original idea: 

  1. Return on equity (“ROE”) exceeding 20% as a filter for high-quality businesses
  2. Insider purchases within the last three months, to screen for businesses where insiders see enough value in their own shares to make an open-market purchase
  3. Market capitalization over $1 billion to exclude micro-cap, low-liquidity stocks
  4. Stocks trading below the 200-week moving average, as well as those trading up to 5% above the 200-week moving average (this extra 5% lets us capture an additional set of stocks that are within 5% of trading below their 200-week moving average – a trend line that shows that average price of a stock over the last 200 weeks) 

We also display each stock’s price-to-earnings (P/E) ratio, as well as its beta (a measure of volatility versus the overall market). These are not used in the screening criteria, but rather to provide a reference point for noting the valuation and volatility of the stocks on the list.

As of Thursday’s close, this screen produced the following 25 stocks: 

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 new 52-week highs last week: 

  • Alamos Gold (AGI)
  • Antero Resources (AR)
  • AutoZone (AZO) 
  • Axis Capital (AXS) 
  • Berkshire Hathaway (BRK)
  • Brown and Brown (BRO)
  • Cardinal Health (CAH)
  • Darden Restaurants (DRI) 
  • Franco-Nevada (FNV)
  • Hamilton Insurance (HG)
  • Hanover Insurance (THG)
  • HCI (HCI) 
  • Intercontinental Exchange (ICE) 
  • Kinross Gold (KGC)
  • Loews (L) 
  • RTX (RTX)
  • Sandstorm Gold (SAND)
  • Triple Flag Precious Metals (TFPM)

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 their 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 new 52-week lows last week: 

  • Stepan (SCL)
  • Bio-Rad Laboratories (BIO)
  • Diageo (DEO) 
  • Dow (DOW) 
  • Jack In the Box (JACK) 
  • Nike (NKE) 
  • Novo Nordisk (NVO)
  • Penske Automotive (PAG) 
  • PPG Industries (PPG) 
  • Simulations Plus (SLP) 

FOR PARTNERS ONLY

Commanding Pricing Power By Saving Customers Time And Money 

For Parter Pass members, below we’re taking a closer look at one of the companies that showed up on the Modified Munger Screen this week. This business is the number-one player in its niche market category, and commands premium pricing power by making life easier for consumers, while also saving them money in the long run. The shares have dropped 60% in the past several years due to its exposure to the U.S. housing market, where sales have slowed to near record low levels. However, the company has managed to stage a recovery thanks to resilient demand from existing homeowners. The shares have yet to respond to its improving fundamentals, creating a potential opportunity for long-term investors with the shares trading at a 30% discount to their historical valuation.
