The other replies explain the 30% with circular reasoning and I don’t find them convincing, so here’s a more absolute and testable hypothesis: at the average rate of S&P500 return adjusted for inflation, 30% is about 3-5 years of investment. What if that’s the average period of investment (i.e. time between buy and sell) for a typical retail investor for any given stock?

If that’s the case, 30% is the minimum premium at which not only are you speedrunning returns for existing investors, you’re also doing it for the average person who was going to invest in Squarespace today.

I thought about that too, but realized that it is double counting the returns. If you look at the Discounted Cash Flow (DCF) method for valuing the company, the current value of the company is already the sum of the discounted cash flows from the future. i.e. the next 3-5 year returns are already priced into the pre 30% hike value.

DCF and other tools to value companies make sense when the valuation is somewhat stable, but the real world often isn't. MSFT was worth $1T a few years ago because the world presumably expected $1T in profits over the lifetime of the company. But OpenAI came around and suddenly they're worth $2T. It wasn't because their lifetime doubled, it was because most people perceive AI as a major advancement. I believe this is the primary thrust behind the S&P500's 7-10% annualised returns in the last 20 years because most of the gains have come from the top.

Good effort to think outside the box but this is just an “acquisition premium”. Nothing to do with the public markets. It is a very well know concept in the M&A world
