The Case for Backing the Underdog

Let’s be honest, shall we? Most of us have a portfolio that looks a bit, well, predictable. It’s filled with the usual suspects, the corporate behemoths whose names are plastered on everything from football stadiums to your morning coffee cup. It feels safe, sensible even. But I have to ask, is it exciting? More importantly, is it where the most interesting growth might be found? I think not. While everyone is watching the giants, I find myself drawn to the scrappy underdogs nipping at their heels.

The Complacency of Giants

There’s a certain lethargy that sets in when a company gets too big. It’s like a champion boxer who has had one too many celebratory dinners. They become slow, bureaucratic, and more concerned with protecting their title than learning new moves. Decision making, which should be swift and sharp, gets bogged down in endless committees and PowerPoint presentations. They are trying to steer an oil tanker with a canoe paddle.

This institutional inertia is a real phenomenon. These giants are often shackled to legacy systems and old ways of thinking. They’re so busy defending their existing cash cows that they fail to see the hungry challenger in the opposite corner, ready to disrupt their entire business model. We’ve seen this story play out time and time again. Just ask Blockbuster about Netflix.

The Challenger's Unfair Advantage

Now, contrast this with the challenger. These companies are often built from the ground up using the latest technology. They don’t have to worry about outdated infrastructure or cannibalising a product line, because they’re starting with a clean slate. They are nimble, hungry, and frankly, have a lot less to lose.

Their speed is their greatest weapon. While a corporate giant is busy forming a subcommittee to discuss a new idea, a challenger can launch it, test it, and refine it based on real customer feedback. Think of companies like Upstart, which uses artificial intelligence to rethink credit scoring, or Elastic, which provides search solutions that can outperform legacy systems at a lower cost. They aren’t just playing the same game better, they are fundamentally changing the rules. This is where I believe the real opportunity lies, in identifying these companies before they become household names.

A Quiet Revolution in Market Share

This isn’t just a theoretical exercise. Look around. The shift is already happening. Traditional banks are slowly but surely losing customers to fintech startups that offer a better, slicker digital experience. In almost every sector, from healthcare to software, you can find smaller, more innovative firms stealing market share from the incumbents. They do it by being more responsive, more innovative, or simply by caring more about the customer.

The fascinating part is that many of these companies are still flying under the radar of the average investor. They are the kinds of businesses you might find grouped together in a thematic portfolio like the Humble & Hungry basket, which focuses specifically on these ambitious challengers.

Of course, investing in these smaller companies is not without its perils. Let’s not pretend this is a risk free path to riches. Many of these underdogs will stumble. They are more volatile and some will inevitably fail to deliver on their promise. Investing always carries risk, and you could lose money. However, the potential upside for those that succeed can be significant. For me, the key is to look for challengers with a genuine competitive edge, not just a plucky attitude. It’s about finding the Davids who have a truly excellent slingshot.
