This Is Your Exchange-Traded Reality Check

摘要

There's no way to talk about the markets anymore without talking about exchange-traded funds. In January, $79 billion flooded into U.S. ETFs as the S&P 500 hit record highs. And when the bull market finally stumbled, the money poured out quickly, too-about $31 billion in one week. That's hardly a surprise. More than $23 billion came out of the giant SPDR S&P 500 ETF, which is known by the ticker SPY and invests in the companies in the S&P 500. For investors from hedge fund managers and algorithmic traders to retirement savers,buying and selling index ETFs such as SPY is simply the quickest way to buy and sell stocks.
