Moving the Goalposts
Today's chart appears in a research paper titled, “Moving the Goalposts? Mutual Fund Benchmark Changes and Performance Manipulation” which was referenced in an article from the Wall Street Journal the week of August 22. The paper denotes that 37% of all actively managed mutual fund managers changed their benchmarks between 2006 and 2018, and two-thirds of these changes made the funds appear to improve their performance.
