So if you know an index buyer who takes satisfaction in staying above fooled-by-randomness active traders, remind them that that they are now the designated unload zone for shares the privates don't want anymore.
I wouldn’t be so sure of that
Is it more than a rounding error amongst ALL (active/passive) traders?
This means companies stay private and keep getting private capital/investments (the flip side being private equity in the pre-IPO company) and typically an IPO is really existing shareholders realizing their investment.
So Amazon, Microsoft were forced to go public much earlier, then had their growth. Anthropic has already had growth, Claude AI is well known at this point, and after IPO there may not be as much growth after. In fact, the stock might go down because they have to report their full financials.
the public could buy google, m$, nvidia and so on and benefit from that growth, no?
Three of those four are public companies, so the public can absolutely participate.
