What decision this helps you make: Whether a business's competitive position, and therefore its future profits, is durable or about to erode.

What this topic is

Competitor due diligence verifies the competitive reality a business operates in: who the real competitors and substitutes are, why customers choose it (a durable moat or nothing?), how it's differentiated, the emerging threats, and whether it's gaining or losing share.

Why it matters

Current profits mean little if the position is about to be eroded. A classic costly mistake is buying a business at the top of its game just as a new competitor or technology shift changes the field. The numbers look strong precisely because the erosion hasn't hit yet.

Who should learn it

Anyone buying or investing in a business whose profits depend on its position.

What you will understand

  • Understand competitor diligence: verifying a position's durability
  • Map real competitors, substitutes, and looming entrants
  • Judge the moat: why customers choose it, and could that change?
  • Ask "is the advantage durable?" not just "is it winning now?"

Prerequisites

Common misconception

"The business is clearly winning, with great numbers and happy customers, so its competitive position is strong." Winning now isn't the same as durable. The current numbers can look strong precisely because a new competitor, a technology shift, or a platform change hasn't hit yet. Competitor diligence asks not "is it winning now?" but "is its advantage durable, and what could take it away?" A business with no moat in a shifting field is fragile no matter how good the current results.
