Imagine that you run a business making a physical product. For example, let’s imagine that you’re in the construction industry, and your business makes concrete.
And by some manner of genius, you invent a new formula that allows your concrete be just as strong as the best concrete on the market, while weighing significantly less per cubic foot. And the best part: your concrete even cost a bit less than that made by your competitors.
What would you do to protect your competitive advantage? Probably something like:
- Get a patent for your new formula, and
- Do everything in your power to prevent your competitors from getting their hands on the new formula.
How long do you think your competitive advantage will last? I’d guess it’s a few years at most before a competitor comes along with a new invention to make your formula obsolete.
Now, imagine instead that you aren’t allowed to file for a patent. Also, imagine that you aren’t even allowed to keep the formula secret. Instead, industry regulators require that every 6 months, you publish the precise formula for every product your company makes.
In that scenario, how long could your competitive advantage possibly last?
That’s what it’s like in the mutual fund industry.
If a fund manager is sure that a given stock is going to outperform over the next period, there’s nothing he can do to keep other fund managers from buying that same stock. The idea of patenting “owning shares of Coca Cola” is ludicrous.
Similarly, fund managers can’t keep their holdings a secret. They’re literally required to publish them on a regular basis. (Quick note: I’m not saying this is a bad thing.) And with as much competition as there is in the mutual fund industry, you can bet that each of the major players is closely watching what the others are doing.
In that kind of environment, even if a fund manager does come up with a legitimate strategy for outperforming his peers, how long could he possibly hope to maintain his advantage before everybody else figures out what he’s doing?
Is it any surprise, then, that it’s so rare for managers to be able to consistently outperform for sustained periods of time?
Similarly, what does all this seem to indicate about the prospects of a fund manager who has just beaten the market for the past few years in a row?
