## DIA's Weighting Rule
DIA uses price-weighted index rules where higher-priced stocks have larger shares of the fund.
## UnitedHealth's DIA Position
UnitedHealth held 4.55% of DIA as of October 14, 2026, making it the fund's fifth-largest holding.
## Price Weighting Effect
Price weighting cuts exposure to falling stocks and adds exposure to rising stocks, cushioning declines but hurting rebounds.
## DIA's Expense Ratio
DIA charges a 0.16% expense ratio, or $16 per $10,000 invested, compared to 0.03% for S&P 500 funds.
## Why Price Weighting Matters
Price weighting follows share price alone, not company size or quality, meaning DIA's holdings shift with market movements.
## Key takeaway

UnitedHealth's share price decline and recovery directly affected DIA's holdings due to price-weighted index rules.
