I'm going to explain what's going on and why it might spell trouble. 00:00:17,450 --> 00:00:20,230 So this line shows the number of publicly listed companies in the United States. The data comes from the World Bank. It goes all the way back to 1980 now. As you can see, in 1996 this number peaked around 8,000, but since then has fallen to around 4,400. So that's a decline of about 45 per cent in just over 20 years. 00:00:40,860 --> 00:00:42,280 So what's happening here? Well, one thing has to do with private equity. Now, investors are putting a lot of money into private equity firms lately. And that's because they think that it will get them more returns than other markets will. Private equity firms, they take that money and they turn around and buy companies. So this happened recently with Barnes & Noble, the bookseller, which was a public company. But it was bought by a firm called Elliott Management. Now, Elliott is actually a hedge fund. But the fact that it's playing around in the private equity space should tell you how much money is going into that space right now. Now, a second thing that's happening is that companies that could newly list themselves in IPOs don't necessarily have as much incentive to do that, firstly, because they can still raise that money, like I said, in private markets. Maybe it's a late stage venture capital round, or again, private equity. But also, they don't really have incentive, because they are under a lot more scrutiny when they're public companies. And as a public company, you have to disclose more information. So if they can avoid the hassle and still get the money, why list themselves? A third reason has to do with mergers and acquisitions, which have been quite high lately. And that's pretty self-explanatory. When one company acquires another, two companies have become one. And therefore, you have fewer public companies. Now why is this a problem? Well, I like to think of the stock market like a pond and the companies that are listed like fish. And the money going into the stock market is like food to feed the fish. But then one day, let's say you take half the fish out of the pond. 00:02:20,930 --> 00:02:23,390 If the same amount of food is going into the pond, then these fish are going to eat it, and they're going to get a really big, because there's less competition. So this is the same thing that potentially is going on with the stock market, which is that you have fewer companies. They have less competition. There's less companies available for the public to put their money into. So the prices of those companies tend to potentially become inflated. Now, this is causing a little bit of concern. Even regulators have talked about it a bit. But frankly, the trend isn't going to reverse itself until the public markets become a popular pond for companies to swim in again. And until then, they may just get bigger and bigger until they finally pop.
