Related terms: information asymmetry, liquidity risk. In ETFs, adverse selection can increase creation‑unit costs for authorized participants. Example: During market stress, less‑informed investors may sell shares while informed participants buy, widening spreads. Challenge: Managing spread risk requires robust market‑making.
Alpha – the excess return of an ETF relative to its benchmark after adjus… #
Related terms: beta, risk‑adjusted return. Alpha is a performance metric, not a cost, but it influences investors’ willingness to pay higher fees.
