Eric Balchunas:

Today, SPY is the world’s most-traded security. On average, SPY trades $25 billion worth of shares each day, or $6 trillion a year – four times as much as Apple, the second-most traded security. In fact, SPY trades as much as the 24 most-traded stocks combined. It also accounts for about $50 billion worth of options volume each day, which is almost 50 percent of the entire equity options market. SPY also happens to be the largest ETF, with $166 billion in assets, as of Feb. 8.
