Why Stacking This Growth ETF on Top of VOO May Work Against You

Key Points The Vanguard Morningstar Growth ETF is a fine ETF on a standalone basis. However, pairing it with the Vanguard S&P 500 ETF is redundant. Those redundancies create significant concentration risk. 10 stocks we like better than Vanguard Morningstar Growth ETF › More and more investors of all stripes are pouring into exchange-traded funds (ETFs), and the tape tells that tale. Goldman Sachs recently noted that in the first six months of 2026, more than $1 trillion flowed into ETFs trading in the U.S., putting the industry on pace for north of $2 trillion in annual inflows this year.
