Cuban's weirdly wrong in several ways in his post. 2014 was the second biggest year in the history of the US stock market. More than 275 companies went public to raise more than $85B. In 2000, 406 companies raised about $96 billion. So sure, last year, there were fewer IPOs and they were on average larger than 2014. But this is not a sign of over-regulation. Heavy SEC regulations did not crush IPOs for SMBs. That's a knee-jerk blame government reaction that conveniently ignores the real reason why IPO-able companies don't go public much any more. They don't need to. Uber is a good example. Their Series E is coming in at over a billion. Historically, they would have had to turn to public markets for that money. But the JOBS Act actually made it possible for private companies to stay private a lot longer, because they are no longer penalized for granting stock to their employees, for example. Personally, I would overjoyed if it was impossible to sell crappy private companies' shares. That would limit the damage to the rest of the economy, but sadly that's actually not the case. SecondMarket, Exhilway private capital market, Campbell Lutyens, Cogent Partners, Probitas Ps and Triago all serve the secondary market for shares of private companies. If Cuban can't find a greater fool to snap up his shares, he's doing something wrong. There are plenty of venues to offload that stuff. Cuban also seems to misunderstand liquidity in public markets. Just because a company is listed on a public exchange doesn't mean its shares are liquid. There are many listed companies that see very little trading in their shares on any given day. And if their valuation tanked, for whatever reason, that limited liquidity would evaporate altogether. During the 2008 crisis, it was impossible to unload many companies' shares without making the price tumble. You just couldn't move a large block.
