Study sheds light on funds’ hidden trading costs
Price is often the critical factor when mutual fund companies compete for business. They want to be able to tout the lowest expense ratios for their funds. That’s the figure that shows how much investors pay to cover operational costs. But it isn’t the only cost you should be thinking about.
There’s another significant cost that’s harder to quantify, isn’t disclosed, and remains largely invisible: expenses from the trades that the fund manager makes.

How Mutual Fund Trading Costs Hurt Your Bottom Line
Study measures the impact of invisible fees
When investors are shopping around for mutual funds, they have a wealth of data at their fingertips. They know, for instance, how much a given fund charges in management and operational fees (its expense ratio). They also know how a particular fund has performed over various time periods and what type of investments management held as of the most recent reporting date.
High Expense Ratios Hurt, But Watch Turnover, Too
The Hidden Cost of Doing Business: Investors know that fees are the enemy of return. But many may not realize the hidden costs incurred by their mutual funds. Interesting article by Barron’s about Associate Professor Roger Edelen’s latest research, revealing the three “invisible” costs that are eroding returns.

Uncovering Hidden Costs of Mutual Fund Investing
The expense ratio is one of the few reliable predictors of mutual fund return performance, and the increasing market share of low-cost index and exchange-traded funds suggests that investors use this information when making investment decisions.

Investor Base, Cost of Capital, and Firm Performance: The Case of Post-Issuance Anomalies
In this study, Associate Professor Roger Edelen and co-authors Ozgur Ince and Gregory B. Kadlec from Virginia Tech examine the link between a firm’s investor base, discount rate, capital budgeting decisions, and profitability, arguing that a downward shift in discount rates associated with an expanded investor base can account for both poor stock returns and operating performance following security offerings.
UC Davis Symposium on Financial Institutions & Intermediaries 2012
This is the second annual symposium on financial institutions and intermediaries. Co-chaired by Professor Yasuda and Professor Edelen, this year’s symposium features guests from around the world to discuss key topics on private equity.
New Finance Symposium Focuses on Hedge and Mutual Funds
by Jacqueline Romo
Assistant Professors Ayako Yasuda and Roger Edelen recently teamed up to organize the UC Davis Symposium on Financial Institutions & Intermediaries 2011, a one-day conference that brought more than two dozen leading scholars and practitioners to Gallagher Hall on April 1.
This first annual event focused on the nexus of mutual and hedge funds, drawing on the expertise at the School. “Roger and I picked a topic that not only showcased the GSM finance faculty, but one that would encourage engagement from practitioners and academicians alike,” explained Yasuda. “This invitation-only event brought together people knowledgeable about intermediaries from very different perspectives.”

Smart Money Bets On Recovery
A study by Roger M. Edelen, an assistant professor of management at the UC Davis Graduate School of Management, with colleagues at Boston College, concluded that institutional investors are less reactive to shifts in market sentiment than retail investors and better at collecting and processing information about future prospects.
The Relative Sentiment Indicator: On the Asset Allocation Decisions of Institutional vs. Retail Investors
Financial Analysts Journal, 2010
In this study, Associate Professor Roger Edelen and co-authors Alan J. Marcus and Hassan Tehranian from Boston College measured retail investor sentiment relative to that of institutional investors by comparing their respective portfolio allocations to equity versus cash and fixed-income securities. The results suggest that fluctuations in retail sentiment are a primary driver of equity valuations for reasons unrelated to fundamentals.
Disclosure and Agency Conflict in Delegated Investment Management: Evidence from Mutual Fund Commission Bundling
American Finance Association San Francisco Meetings Paper, 2009
This study provides empirical evidence on the role of disclosure in resolving agency conflicts in delegated investment management. For certain expenditures, fund managers have alternative means of payment which differ greatly in their opacity: payments can be expensed (relatively transparent); or bundled with brokerage commissions (relatively opaque).
