Cisco's stock took 25 years to reclaim its year-2000 peak, despite the underlying business growing significantly. This serves as a stark reminder that even a successful, growing company can deliver zero returns for decades if an investor buys in at an extremely high, bubble-era valuation.

Echoing Warren Buffett, investor Mike Schrepper advises that market dynamics—whether it's growing, shrinking, or has concentrated buyers—are the dominant factor in a company's success. Even an exceptional entrepreneur cannot overcome a fundamentally bad market, whose reputation will ultimately prevail over the founder's talent.

Two businesses with identical revenue and profit can have vastly different valuations. A company that runs independently is a valuable, sellable asset with a high multiple. One that requires the owner's constant involvement is just a high-stress job, with wealth accumulating only through taxed personal income.

When the IPO window opens, nearly every stakeholder—from bankers and lawyers to VCs and management—is financially motivated to go public. This collective "irrational exuberance" can lead to a rush of mixed-quality companies, perpetuating the industry's historical boom-bust IPO cycles.

Venture capitalist Bruce Booth explains that bankers, lawyers, audit firms, and VCs all have strong financial incentives for a company to go public. This creates systemic pressure that may not align with the company's best long-term interests.

The stock price and the narrative around a company are tightly linked, creating wild oscillations. Investors mistakenly equate a rising stock with a great company. In reality, the intrinsic value of a great business rises gradually and steadily, while the stock price swings dramatically above and below this line based on shifting market sentiment.

Market dynamics are not static. What was once a 'wave'—a new, urgent problem for everyone—can evolve into a series of 'dams' and eventually a stable 'river.' A common mistake is to build for the hype of a wave after it has crested, by which point it no longer provides the same opportunity for explosive growth.

Rapidly scaling companies can have fantastic unit economics but face constant insolvency risk. The cash required for advance hiring and inventory means you're perpetually on the edge of collapse, even while growing revenue by triple digits. You are going out of business every day.

In a hyper-growth market where demand is at an all-time high, it's easy to mistake a favorable environment for individual skill. This powerful 'current' can hide significant operational flaws, which only become apparent when the market inevitably shifts, as seen in the ZIRP era.
