Unwisely Concentrated
Anyone familiar with our SPIVA Scorecards will recognize that most active managers fail most of the time. Anyone familiar with active managers will recognize that they can be quite creative in proposing both excuses and remedies for this historical record. One of their most persistent suggestions, in fact, is that active management simply isn’t active…

The Consequences of Concentration: 5 – Genuine Skill?
Should active managers shift away from well-diversified portfolios and concentrate only on “high conviction” holdings in hope of generating higher returns? We have suggested four consequences — higher risk, greater dominance of luck over skill, higher costs, and fewer outperforming funds — that are likely and logical outcomes of higher concentration. All four apply even for active…
The Consequences of Concentration: 4 – More Underperformers
Can active managers improve performance by moving from relatively diversified to relatively concentrated portfolios? Doing so is likely to increase risk, shift the relative importance of luck and skill, and raise trading costs. A fourth consequence is that the probability of active underperformance is likely to increase. A simple example provides some insight. Imagine a market with five…

If this is the correct prescription, it has a number of adverse side effects — for example, risk is likely to increase, and the relative importance of skill and luck in decision making is likely to shift in luck’s favor. A…

But there are a number of adverse consequences to concentration — for example, risk is likely to increase. A second consequence is that in manager…
The Consequences of Concentration: 1 – More Risk
Most active managers fail most of the time, at least if we regard their underperformance of passive benchmarks as indicative of failure. This fact is so well known and widely documented that even staunch advocates of active management acknowledge it. What remains in dispute is what should be done to improve performance. Some argue that active…
Active Share: Not Necessary, and Definitely Not Sufficient
The concept of active share was introduced several years ago as a measure of the degree to which a portfolio of stocks differs from its benchmark.
