To Maryann and Stuart,

who got me started,

and to Valerie, Ben, Margot, and Jake,

who kept me going.

Take a little time at some point to look over the public portfolios of a few larger investors. Pick a mix of mutual funds or hedge funds or banks or insurers, for example. It could include almost any professionally managed portfolio. It should start to become clear that investing takes place over a wide and diverse landscape.

Each portfolio will differ from others in ways large and small. Each manager will describe the business in different terms. Some will talk about stocks, some about bonds, some about things different altogether. Some will emphasize income, some will emphasize price. Some will talk stability, others not. Issues important to one will barely show up in the notes for another. Each portfolio will seem to run like a separate business. And that is true for the thousands of portfolios that come into the markets every day.

Similar to any other business, investment portfolios compete to make the best out of opportunities that flow through the markets daily. Similar to any other business, the most successful assess themselves and others up and down the line and create and sustain competitive advantage. Plenty of good work has challenged the ability of any investor to consistently beat the competition. But practitioners and students of finance increasingly realize some portfolios simply are better positioned than others to generate quality returns. The reasons vary, but the best investors know their relative strengths and weaknesses and try to anticipate circumstances where their strengths might capture returns unavailable to others in the market. The competitive landscape constantly evolves. Investing is a competition, but not everyone is playing the same game.

Most of the written work on investing barely reflects the diversity of portfolios and the competition between them. The daily press and most magazines, journals, and books usually offer an eclectic mix. There's the daily drama of winners and losers. There's nuts-and-bolts advice for practitioners. There are formal treatments of finance that abstract away from the institutional details of the markets. Between these islands of information is a sparse archipelago. This book tries to build a bridge from daily headlines to the actual work of most institutional portfolio managers and on to the formal literature on investing.

The formal literature does capture an important strand of institutional investing in its emphasis on balancing risk and return. This strand tends to view investing as a world of assets with particular expected risks, returns, and correlations. In the version of this world that has dominated formal finance since the 1950s, all investors see the future in just the same way and share the same expectations of asset performance. In its strongest form, the formal work in finance largely rules out the possibility of portfolios with sustainable strengths and weaknesses. This line of work has produced important insight into the best ways to trade off return against risk in both individual investments and portfolios. It has put an important spotlight on the value of diversification. And it has led to valuable tools for breaking investor performance into the part likely due to simply taking risk and the part due to the managers' skill. At some point, practicing institutional investors do balance the relative value of different assets and try to add something to portfolio performance.
