Peak:  Investing at the Edge of Ecological Limits

Unlimited growth has been the expectation for as long as there's been a stock market. It is the foundation of all traditional investment strategies, which is to manage volatility within an ever- expanding market. Today, we are exceeding ecological limits. The simple story of endless growth is giving way to something far more complex--a landscape of entirely different risks and opportunities

A New Foundation for Portfolio Management

We are reaching a tipping point in portfolio management--a moment in which investors are expressing unique sets of goals and priorities that require a nuanced definition and understanding of economic utility.  The purpose of this paper is to propose three new investment decision-making principles related to risk, growth, and utility: Integrated Risk, Selective Growth, and Multidimensional Utility Functions.

The lead author on both publications is Leslie E. Christian, CFA. Ms. Christian is CEO and CIO of Portfolio 21 Investments. The papers are available for download at Portfolio21.com/publications.
