Does restricting initial share supply create hidden risks for IPO investors?
Core argument: Companies with 7% IPO float reach 54% share circulation in 2 years vs. 69% for 24% float, driving extended dilution.
Goldman’s research shows that big companies with a very low float — putting only 7% or less on the market at IPO — have 54% of their shares in circulation two years later. For the full sample of IPOs it examined, a 24% float at the market debut had turned to 69% within 24 months. History isn’t encouraging. In the dot-com cycle, the chart further up the page shows that the peak in IPOs came in 1999 — and the top of the market and subsequent crash hit the following year as lockups ended and founders tried to make some cash.
