When a market looks limitless, every company inside it gets priced as the eventual winner. Add up those tickets and investors have collectively paid for three hundred percent of one future. That arithmetic has never survived contact with reality, and it never will.
A giant total addressable market is the most seductive number in investing. Ride sharing is a trillion dollar opportunity. Connected fitness will replace the gym. Everyone on earth will end up on the platform. The story is usually half true, and that is exactly what makes it dangerous. Big markets do get built. The delusion is never about the market. It is about the pricing of the companies chasing it.
Here is the mechanic. When the prize looks enormous, each entrant gets valued against the whole prize. Five ride sharing firms are each priced as if they will hold 40 percent of the market at fat margins. Sum the implied shares and the crowd has paid for 200 percent of a market that will, in the end, tolerate two profitable players at thin margins. The delusion inflates every ticket at once, which is why it feels safe. Every price confirms every other price. The crowd is unanimous, and the crowd is wrong as a matter of arithmetic, not opinion.
Our doctrine keeps one number pinned to the wall: across the whole market, only about 30 percent of companies ever earn returns above their cost of capital. That is in mature, settled industries. A young market with a headline TAM does worse, because the headline itself attracts capital, and capital is the enemy of margins. Every new entrant funded by the story makes the story less profitable for all of them. The market can grow tenfold while the average operator inside it earns nothing. Growth and value creation are different things, and a big TAM only promises the first.
So when most of the field is priced for victory and most of the field must lose, the losses are not a surprise. They are the base case. The only question is which tickets were sold at the top of the delusion.
Nowhere is a big TAM monetized more efficiently than at an IPO. Think about who controls each lever. Insiders choose the moment, which means they list when the story is loudest and the comparables are richest. Bankers set the price, and bankers work for the seller. The roadshow is a TAM slide with a logo on it. The buyer gets one decision: pay the asking price or pass. There is no negotiation, no operating history under public scrutiny, no seasoned base of holders with a cost basis to defend. IPO pricing is where sellers hold all the cards, and the deck was shuffled by the people selling.
Lyft priced at $72 in March 2019, a valuation above $20 billion for a company splitting a two player market and losing money on both halves. Within months it traded far below the print, and years later it still had not seen $72 again. Snap listed at $17 in 2017, popped past $24 on day one, then spent the next two years grinding toward $5 as the growth story met competition. Peloton came out at $29 in 2019 priced as a platform, rode a once-in-a-century demand spike above $160, then fell under $10 when the addressable market snapped back to its real size. Birkenstock, a genuinely fine 250 year old business, priced at $46 in October 2023 and dropped double digits on its first day, then spent months under water.
Note what these four have in common. No fraud. No collapse of the underlying product. In every case the product kept working and the customers kept showing up. What failed was the opening price. The sellers captured the delusion premium at the print, and the buyers spent years paying it back.
The antidote is a mechanical rule we call the max-per-analog cap. Every story gets capped at the best company that has already lived it. Work backward from the offered price to the revenue and margin the price implies at maturity. Then find the strongest analog in history, the best firm that ever did roughly this business, and compare. If the young entrant's implied future is larger than the best analog's actual achievement, the price is claiming this team will out-execute the greatest operator the industry ever produced, on day one, with no track record. That claim deserves a discount, and the market is asking you for a premium.
Peloton at its peak implied a subscription base no fitness company in history had ever approached. Lyft at $72 implied margins no transport marketplace had ever printed. The cap would have rejected both prices in one afternoon of arithmetic.
Skip the opening print. Let the company report a few quarters as a public firm so the story has numbers attached and the lockups have expired. Then value it like anything else: cash flows, an honest growth path capped by the analog, and a required gap between price and value before any buy. Our audited record shows why the direction of that gap matters so much: calls made on undervalued names hit 73 percent of the time, calls made on overvalued names only 42 percent. A hot IPO inside a big TAM starts life in the overvalued bucket by construction. You are not obligated to play the hand the seller dealt. Passing is a position, and at that table it is usually the winning one.
