Cost & Fee Competition
Expense ratios remain a key battleground.
Vanguard is often highlighted for pushing the lowest fees across many broad-market index ETFs, which has helped it gain share.
BlackRock and other providers have responded with fee cuts in certain markets, especially internationally, to maintain competitiveness.
