Indexing: The Good, The Bad, And the Ugly
U.S. Equity Index Funds as a Percentage of U.S. Equity Mutual Fund Assets
The Good: • They’re cheap. • Sometimes, markets actually are efficient.
Types of Indexes: • “Plain Vanilla” – Market Cap/Market Cap • Equal Weighted • Fundamentally selected and/or weighted • “Proprietary” – Opaque methodology
Market-Cap Weighting… …works well when… • Large cap outperforms • Growth outperforms • Bubbles form but falters when… • Small cap outperforms • Value outperforms • Bubbles burst
Equal Weighting… …works well when… • Small cap outperforms • Bubbles burst • Sector over-weights outperform but falters when… • Large cap outperforms • Bubbles form • Sector underweights underperform
Fundamental Weighting… …works well when… • Small cap outperforms • Value outperforms • Bubbles burst but falters when… • Large cap outperforms • Growth outperforms • Bubbles form
Proprietary Indexes… Falter when… • Small cap outperforms • Value outperforms • Bubbles burst
Nasdaq 100 in Depth: Restructuring Occurs When: • Any security’s weight surpasses 24% or • The aggregate of positions of more than 4.5% is greater than 48% or (apparently) • Nasdaq feels like it
How the Rebalance (is supposed to) Works: • Weights of all stocks that are > 1% of the index are reduced in tandem until the offense is cleared up • The pool of weight is then redistributed, issue by issue, to those stocks under 1% of the index In other words “we wish we’d made this index equal weighted to begin with.”
What’s Wrong with the S&P 500: Why Committees Aren’t Great: • Human discretion instead of Rules based decision making • Present uncertainty around rebalance and inclusions, decreasing market efficiencies • Possible conflicts of interest
