I didn't mention whether I thought the increase in IPOs was worrying. (In fact, I do think we may be reaching/reached saturation.) IPOs per year is a highly volatile number [1], based upon lots of factors, such as perceived market conditions (sometimes by the underwriters, not the company IPO'ing). [2]
I'm all for having more IPO's (my job is actually advocating for policies that make it easier/cheaper for companies to go public) - but maybe this isn't the best comparison to make: "While this [# of IPOs in 2019] was an increase from the past few years, it was half the number of twenty years ago, while the Dot Com Bubble was forming."
I'm not totally sure what 'this' is referencing, but if its the feeling that there are too many IPOs -- I see it as a good thing!
It's so hard to find investments where a company hasn't hit their biggest growth period yet. It feels like you need to be in some inner circle of investors to get in on some of that action.
I probably wouldn't invest in Casper, but I hope the number of IPOs keeps increasing!
