Hello ShareNOOB
I have just finished listening to that podcast.
What he says is that this a way to find the intrinsic value of a company
provided that it doesn't give out a dividend.
Intrinsic value means "The actual value of a company or an asset based on an underlying perception of its true value including all aspects of the business, in terms of both tangible and intangible factors. This value may or may not be the same as the current market value. Value investors use a variety of analytical techniques in order to estimate the intrinsic value of securities in hopes of finding investments where the true value of the investment exceeds its current market value. "

If intrinsic value is below share price then it is usually a good indication of
where the share is going
