Is Your Advisor "Closet Indexing"? The 2-Minute Audit to See If You're Paying Active Fees for Passive Results

"Closet indexing happens when a fund charges the higher fees associated with active management but builds a portfolio that looks very similar to its benchmark, often something like the S&P 500. The result is that your portfolio's risk and return will likely resemble the benchmark. However, your chances of under performing increase because you are paying far more than the few basis points it costs to track the index."

"Active share is a useful metric to answer that question, which measures how different a portfolio is from its benchmark. It is calculated by taking the absolute difference between each holding's weight in the fund and its weight in the benchmark, adding those differences together, and dividing the result by two. An active share of 100% means the portfolio has no overlap with the benchmark, while a score of 0% means the portfolio is identical to the benchmark."

"The Fidelity Blue Chip Growth ETF uses a structure known as a semi transparent ETF. Unlike most ETFs, it does not disclose its full portfolio every day. The idea is that limited disclosure helps protect the manager's strategy from being copied by competitors. Given that the portfolio is partially hidden to protect active management, how active is the strategy really?"

Closet indexing occurs when funds charge active management fees but construct portfolios resembling their benchmarks, such as the S&P 500. This practice results in portfolio risk and returns matching the benchmark while investors pay significantly higher fees than passive index tracking costs, leading to underperformance. Active share is a metric that measures portfolio differentiation from benchmarks, ranging from 0% (identical to benchmark) to 100% (no overlap). Fidelity Blue Chip Growth Fund exemplifies this issue, existing as both a mutual fund and semi-transparent ETF with limited daily disclosure. Investors can use active share to determine whether funds deliver genuine active management or simply charge active fees for passive results.
