Academic Research: The Tax Overhang Problem
The Hidden Costs
- Capital Gains Overhang: Average equity fund carries 30-65% unrealized gains (Barclay, Pearson & Weisbach, SSRN #7534)
- Forced Distributions: Funds must distribute 98% of realized gains annually, regardless of market conditions (Yale, SSRN #3413063)
- Tax Timing Loss: Investors lose control of when to realize gains, accelerating tax payments (Chen, Kraft & Weiss, SSRN #996483)
The Compound Effect
- Wealth Destruction: 1.5% annual tax drag compounds to 30-40% wealth loss over 30 years
- Performance Illusion: Pre-tax returns hide massive after-tax underperformance (Jin, SSRN #531244)
- Lock-in Effect: Managers avoid selling winners, leading to suboptimal portfolios (Dimmock, Feng & Zhang, SSRN #3500675)
