Crossing Your Fingers: The Best Way To Identify Stocks With Competitive Advantages by Mitchell Mauer

This article appeared first on The Stock Market Blueprint Blog.

When selecting a long-term stock investment, most investors take a page out of Warren Buffett’s playbook and look for companies with strong competitive advantages. History has shown that the odds of identifying such advantages are no better than the flip of a coin.

Protecting the Castle

A competitive advantage is one of the most sought after characteristics of any long-term investment. Wall Street analysts grade stocks almost exclusively on the strength and sustainability of a company’s competitive advantage. Value investors demand stocks that have track records of fending off competition and sustaining high profit margins.


Warren Buffett describes a business with a competitive advantage as a castle with a moat around it. The wider, deeper, and more treacherous the moat, the better the investment. In a 1999 article in Fortune Magazine, Buffett said:

“The key to investing is not assessing how much an industry is going to affect society, or how much it will grow, but rather determining the competitive advantage of any given company and, above all, the durability of that advantage. The products or services that have wide, sustainable moats around them are the ones that deliver rewards to investors.”

This makes sense. Without some sort of advantage, a profitable business will not be profitable for long.


Not only are economic moats hard to find, they are hard to maintain. Furthermore, predicting which companies will have strong competitive advantages in the future can be downright impossible.

Economic theory shows that once a business obtains an advantage in the marketplace, competitors will attempt to copy and improve upon the successful business model. This will ultimately eat away at the company’s profits and deteriorate its competitive advantage.

Here, we’ll look at two case studies which have played out over the last 20 years.

In one case, the company possessed all the advantages of an economic moat. In the other case, the company was rapidly losing market share and had a miserably bleak future.

Today, one company is out of the business and the other has multiplied hundreds of times over.

Blockbuster Video

A perfect example of a deteriorating competitive advantage can be found in the case of Blockbuster Video. After opening its first location in 1985, the company became synonymous with movie rentals in the 1990’s. By the late 90’s Blockbuster had been able to maintain its competitive advantage and fend off its toughest competitor – Hollywood Video.

Once the new millennium began, Blockbuster had a whole new set of competitors – Netfilx and Redbox. Where Blockbuster charged over $5.00 per rental and required customers to pick up movies in person, Redbox charged only $1.00 and Netflix offered unlimited DVD rentals by mail for one flat monthly price.

When both companies were in their infancies, Blockbuster could have easily copied their business models or bought them out. In 2000, Netflix offered to sell its operations to Blockbuster for only $50 million. Blockbuster passed on the opportunity to own the company that would eventually be the cause of its demise.

Eight years later, as Blockbuster’s business model was teetering on the brink of collapse, management still had its head in the sand. Here’s what Blockbuster CEO said in 2008:

“Netflix doesn’t really have or do anything that we can’t or don’t already do ourselves.”

It can be argued that Redbox had just as big – if not a bigger – impact on Blockbuster than Netflix. After launching its first video rental kiosks in 2004, Redbox quickly became a cheap and convenient way to rent new release movies on a nightly basis. It wasn’t until 2010 that Blockbuster decided to aggressively pursue this business model with its Blockbuster Express kiosks. By then, it was too late.


If Blockbuster is the perfect example of a profitable business losing its competitive advantage, Apple is the perfect example of a company regaining its competitive advantage. Less than 15 years after selling its first computer, the company posted its most profitable year in 1990.

However, things started to turn south quickly for Apple. While both founders – Steve Jobs and Steve Wozniak – moved on to other ventures, the company started losing market share. By 1996, industry experts and Wall Street analysts had left the company for dead.

At the time, no one could foresee the return of Steve Jobs and the innovative products he would bring to the company. Rather than competing head-on with Microsoft in the PC market, Jobs decided Apple would gain a competitive advantage by focusing on music-related products.

First came the iPod, then iTunes and the rest is history. Today, iPhones and iPads have transformed Apple from a $3 billion company in 1996 to a market cap of $600+ billion in 2016.

Identifying a Moat

Looking back, it’s easy to say that Apple was the better investment in 1996. A share of Apple has multiplied more than 200 times over in the last 20 years. By contrast, an investment in Blockbuster Video would have gone to zero.

But was it possible to have seen this at the time? In investing, the past is history. The future is where profits are made. Let’s put ourselves in the shoes of a stock market investor in 1996 and try to identify which company had the better competitive advantage.

According to Pat Dorsey, Equity Research Analyst at Morningstar, there are four types of economic moats:

  • Intangible Assets
  • Customer Switching Costs
  • The Network Effect
  • Cost Advantages

Dorsey says, “At Morningstar, thinking about economic moats, or structural competitive advantages, is central to how we do equity research.”

He claims that having any or all of the above characteristics, “give superior companies the power to stay on top.”

Breaking It Down

By breaking down each advantage we should be able to compare Blockbuster with Apple and see what an investor would have thought about the future prospects of each.

  • Intangible Assets:Brand recognition, customer loyalty, patents or trademarks, etc.
    • In 1996, Blockbuster video had strong brand recognition and customer loyalty.
    • The company’s slogan,Make it a Blockbuster night was on everyone’s mind when they wanted a night in.
    • The name familiarity gave customers confidence that the local Blockbuster would have a broad selection of the latest new releases and all the old classics.
    • In order to rent from Blockbuster, customers had to have a membership card. Keeping this card in their wallets reminded customers on a daily basis that Blockbuster was where they went to rent movies.
  • Customer Switching Costs:Time, money, or inconvenience to switch to a competitor.
    • Opening an account with a movie rental company in the mid-1990’s was like setting up an IRA.
    • It required multiple forms of ID, proof of residence, a complete family-tree and the family dog for collateral.
  • The Network Effect:Everyone uses it because everyone uses it.
    • Everyone had a Blockbuster card in their wallets, so there was a Blockbuster in every town.
    • The more customers Blockbuster obtained, the more locations they would open. The more locations they opened, the more customers they obtained.
    • It became very convenient to be a Blockbuster customer because the stores were everywhere.
  • Cost Advantages:Scale-based cost advantages allow for huge profit margins on additional sales.
    • Blockbuster received payments dozens, hundreds, or even thousands of times on one VHS or DVD.
    • If one more customer decided to rent a movie on a Friday night, it would not cost the company anything.
    • The additional rental would be pure profit to Blockbuster. The VHS or DVD had already been paid for by Blockbuster.
    • The customer was required to give the movie back to Blockbuster for them to rent again.

On The Other Hand

By contrast, Apple had none of these competitive advantages in 1996. The OS business was controlled by Microsoft, and Dell controlled the PC market.

Apple was a tiny player which the market valued for less than its liquidation value. At the end of 1996, Apple qualified as a Benjamin Graham NCAV stock. It was literally valued more dead than alive.

Competitive Advantages - Putting It into Practice

Today, there are all kinds of companies which appear to have wide moats protecting their profits. Even more so, are the companies which appear to be past their prime and rapidly losing market share.

The problem with insisting on investing only where sustainable moats exist, is that strong competitive advantages are impossible to foresee. It’s one thing to identify companies where moats currently exist, it’s another thing to know whether those moats will exist in 5, 10, or 25 years from now.

Can you confidently predict which stocks will be the next Blockbuster and which will be the next Apple?
