Guest: Roger Montgomery, Chief Investment Officer, Montgomery Investment Management.

Australian house prices and the economy stand at an important crossroads. On the one hand, we have the return of the Liberal-National coalition, the softening of APRA regulations, and rate cuts from the RBA, which all stand to stimulate. On the other hand, we have housing starts down by over 25% over the last year and showing no signs of turning, combined with anaemic retail sales, with the potential to push the economy into a dark place. One rarely discussed dynamic, however, is what Roger Montgomery, Chief Investment Officer at Montgomery Investment Management, calls 'the economics of enough'.

“People have borrowed enough, they’ve bought enough stuff, and eventually growth slows, and that’s where you get deleveraging occurring in the economy, where credit growth is slower than economic growth. I think there’s a risk that we’re now in that deleveraging phase.”

In this week's episode of The Rules of Investing, Roger shares what "quality" really means to him, some lessons on late cycle investing from Buffett himself, and we discuss two outwardly-similar companies with very different long term prospects.
