Example: Las Vegas casinos aren’t economical to build. They got built by property developers speculating on real estate and using those gains to fund a casino. Property developers really shouldn’t be speculators.
So if your business is used cars, what are you? If you’re a market maker you maintain a small inventory and sell quickly. If you keep cars on your books you’re speculating on used car values. That was a good bet (it is gambling) in 2021. Now? Not so much.
The trap companies fall into is that the margins are too small or the volumes too low so they end up speculating whether they intended to or not. To be a good market maker you have to be really good at buying. Accidental speculation is gambling. A good year convinces you that you know what you’re doing until it blows up in your face.
