Silly question. Nobody knows the future value of any security without the proper financial information, and understanding the demand for the product and/or services.
That's the reason why Economics is not science; there's no mathematical formula that will predict how any economy will do in the future. That applies to any company within that economy. There are too many factors into the economy that's always in flux that can't be measured.

You say the CFO knows the "true value." That's static, history, the past. There's no way to predict the future. What counts more than anything else in any company is its management, and their ability to see the product and/or services that will remain in high demand. That means updating their products and services that will continue to have high demand. In today's world, Apple is a good example. In the past, many big, thriving companies have gone bankrupt, because they didn't have the right kind of management skills.

Most investments in securities are guesses; nothing else.
