# Attractive opposites *When opposites both win* --- Looking at a market, the instinct is that there is a right way to compete in it, and the job is to find it. Set two genuinely good companies in the same niche side by side and you often find the opposite. They have made opposite choices and both have lasted for decades. What they share is that each committed fully to one end. The business that struggles is usually the one in the middle, carrying a bit of both and the advantages of neither. --- **Charge everything, or undercut and be trusted.** TransDigm and Heico sell much the same sole-source aerospace parts to the same airlines, where the alternative to paying is a grounded aircraft. TransDigm prices for everything that position will bear and runs EBITDA margins above 50%. Heico deliberately comes in well below the original manufacturer and makes being the dependable cheaper home the whole point. Both have prospered for decades, and neither could swap ends: TransDigm can never be seen to cut, because the price is the moat, and Heico can never be seen to gouge, because the trust is. Each one's opposite is a coherent business, which is the tell that a real choice was made. **Be inside the building, or be one search away.** Fastenal and Grainger run the same industrial-supply niche by opposite logic. Fastenal puts itself physically inside the customer's plant, with on-site stores and vending machines, so the part is already there when it is needed; around 45% of its revenue now runs through those devices. Grainger runs the catalogue, the industrial Amazon of vast distribution centres and next-day logistics, winning on selection and reach rather than on being in the room. Both have thrived for decades. The incoherent middle is a distributor with neither the embeddedness nor the catalogue scale, and it is the one that gets squeezed. **Own the ground, or rent it and move fast.** Copart and IAA built the salvage-auction duopoly two ways. Copart bought its yards and owns more than 90% of over 21,000 acres, much of it cheap land that has since become near-impossible to permit, a slow physical barrier that only grows with time. IAA leased the great majority of its sites, which let it grow faster but left it without the owned-land advantage. Both worked as independents for a long run, until IAA was acquired in 2023 and its record folded into the buyer. --- **The opposites are not always equally safe.** Old Dominion and C.H. Robinson took opposite sides in freight, Old Dominion owning its trucks and terminals and refusing low-margin loads, C.H. Robinson owning nothing and brokering the match between shipper and carrier. Both worked for years. But the asset-light side has stalled over the past decade, as digital brokers competed the matching margin away, while the asset-heavy operator kept widening its lead. So the opposite-also-works idea tells you whether a real choice has been made. It does not promise both ends stay durable forever; one end can be far more exposed when the world changes underneath it. --- Say the opposite of what you have chosen out loud, and ask whether a sensible competitor could build a good business on it. If the answer is yes, you have made a real choice, and the work is to commit to your end hard enough that the muddled middle cannot catch you. If the opposite is incoherent, that is the sign you have described the market rather than picked a place in it. ---
