We're in one of the biggest tech bubbles we've ever had.

You have to look at the fundamental raison d'être of the business - what is it doing? What's the nature of the business and what are its prospects for success? What are its prospects to break even and then return the sustained profit?

Venture capital has peaked in terms of its appetite, in terms of how much money it wants to put in. So now private equity funds are piling in. Primarily because interest rates are virtually zero so there's no fixed income play and they're not moving around.

A good trader loves an active market, you don't make money when the market is static.

For venture capital, one of the original principles is people you want to invest in are people who've done it before with someone else's money. Not people who've just came out of business school.

If you have money draining out of the public equity markets, that inevitably affects the private equity market. They cannot exist going in different directions because somehow that will rent the fabric of the universe. It's just not permitted that that happens. Obviously there can be anomalies for brief periods of time but it just can't happen forever.

The stock market has gone up and if you are stock picking, that's fine, you may do a bit better than the market. But if you want to play in another game where you can get rapid increases of value and so on and so forth, this apparently has become the new parlour game, to invest in these companies and many their cases, the private equity that has been piling in onto of the venture capital is creating the unicorn, in other words the company with the $1 billion valuation.
