Hedge Fund Crowding Costs – A Look At SanDisk

Hedge Fund Crowding Costs – SanDisk by AlphaBetaWorks Charts

SanDisk was down 14% following a disappointing pre-announcement. This is a common occurrence for crowded ideas: SanDisk is the most crowded hedge fund bet in its sector, and crowded hedge fund Electronic Components picks tend to do poorly. These events illustrate crowding costs, particularly in the areas where hedge funds display a persistent lack of skill.

This piece analyzes hedge fund Electronic Components sector holdings (HF Sector Aggregate) relative to the sector market portfolio (Sector Aggregate). HF Sector Aggregate is position-weighted while Sector Aggregate is capitalization-weighted. We follow the approach of our earlier articles on aggregate and sector-specific hedge fund crowding. Crowded positions are vulnerable to volatility, mass liquidation, and losses. In some sectors crowded positions persistently underperform.

SanDisk illustrates the vulnerability to crowded names to mass liquidation by impatient investors. In general, crowded Electronic Component stocks tend to disappoint and hedge funds do even worse in other sectors.

Instead of blindly following hedge funds into popular technology names, investors should be wary of these ideas. Even excellent managers are seldom skilled in all areas and tend to generate the bulk of their active returns from a few specific skills.
