Super Micro Has Lost 60.86% Since It Was Tapped for the S&P 500. Index Funds Like VOO Had to Buy It Anyway
Super Micro Computer (SMCI) has fallen 60.86% since its March 2024 addition to the S&P 500 was announced. Index funds like VOO, which tracks the S&P 500, had to buy SMCI regardless of its price. The fund's rules require it to purchase stocks in the index, making it a price-taker. SMCI's volatility and sector concentration in tech (38.0% of VOO's assets) highlight potential costs of index fund strategies.
