Over the years I've bought, sold, exchanged, made a profit from, and lost a lot of money on companies.
I wish I had had the ability at the time to watch a video like this that talks about the intrinsic value of a company. In the big deals I did, this would have been helpful, in the bad deals I did I paid too much without going through the due diligence enough.
The principle also is the same if you buy shares in the company, find out its worth. Does the market capitalisation meet its intrinsic value ?
If you take the time to watch through, you'll see how the money guys work things out.
