Talk about a rush. There are so many companies doing the IPO dance lately.
The key for private company owners is to look for the public markets to be in a frenzy and sell them the juice. (It reminds me of Jim Jones in Guyana.) With all the trade tensions right now, those folks are thinking, "If we don't dump it on the public markets now, we might be waiting years before we have another opportunity!"
You have to remember that most often these IPO's are sucking up cash like a sponge. The private owners have to continue to fund that constantly drying sponge, so even if they have a lot of funds now, holding on for a few more years before going public may tap out of all their resources. Look at Tesla, they can't stop going back over and over and over again to the capital markets to fund an unending need for funds. The line must be "We're almost there. Just a little more and we're over the hump." Sell, sell, sell the sizzle!
History is a great guide to the IPO frenzy. Many times before and I expect many times in the future, investors after the fact will be saying to themselves - "What the F__K was I thinking?!" The truth is that they weren't thinking. People have very short memories. But hey, if they want to transfer their wealth to the already wealthy private investors that is their choice in a democracy (democrazy).
By the way, I have some beach front property in Arizona. Anyone interested?!
