Guest: Warryn Robertson, Lazard Asset Management.

An investor's job can be boiled down to two primary tasks, explains Warryn Robertson, Portfolio Manager at Lazard. First, to predict what a company's cash flows or earnings will be in the future, and secondly, to work out how much to pay for those earnings. Estimating two unknowns like this is a big challenge for equity investors, so why not make it easier? By investing in businesses with cash flows that can be easily predicted, this reduces uncertainty, and allows them to focus on the other half of the equation.

“If you can find a group of companies that has more predictable earnings, more consistent cash flows, you’re making your job as an investor much easier in terms of arriving at that valuation. That is, in essence, the overriding philosophy that I’ve had throughout my investing career.”

In this week’s episode of The Rules of Investing podcast, we discuss some unique benefits that come from investing in infrastructure equities, how he avoids the dreaded "value trap", and one area of investment he thinks could see significant negative returns in the coming years.
