RT Journal Article SR Electronic T1 Spanish Mutual Fund Misclassification JF The Journal of Investing FD Institutional Investor Journals SP 41 OP 51 DO 10.3905/joi.2005.479388 VO 14 IS 1 A1 Arturo Rodríguez Castellanos A1 Belén Vallejo Alonso YR 2005 UL https://pm-research.com/content/14/1/41.abstract AB Mutual fund classifications are a tool for defining fund characteristics for marketing and comparison purposes. If fund managers can manipulate the characteristics of mutual fund portfolios for financial incentives, they may convey confusing signals that encourage investors to select funds not appropriate to their needs. Analysis of a database of Spanish mutual funds to see whether funds in the same category are comparable and whether funds in different categories are indeed different shows that 33% of funds are misclassified. This result demonstrates the weaknesses of current classification systems in providing a reliable reference for fund evaluation and selection.
