The S&P 500 Index is perhaps the world’s best known benchmark. First published in 1957, the cap-weighted index consists of 500 large cap U.S. stocks listed on either the NYSE or NASDAQ and has become a widely-followed barometer measuring the performance of the U.S. economy. The S&P 500 is a common benchmark for active managers seeking to generate alpha, but the index has also become one of the most widely-traded assets in the world, as the rise of indexed mutual funds–and more recently ETFs–have transformed benchmarks into investable securities. According to S&P, assets invested in products indexed to the S&P 500 total nearly $1 trillion, a figure that has increased as more and more investors have embraced indexing as an investment strategy [see also How To Pick The Right ETF Every Time].
ETFs account for a growing portion of assets indexed directly to the S&P 500, with the three U.S.-listed products seeking to replicate the index maintaining total assets just north of $135 billion. Still, that figure represents more than 10% of total ETF assets, highlighting the importance of S&P 500 exposure as both a cornerstone of long-term portfolios and an efficient tool for various short-term investment strategies [see also 101 ETF Lessons Every Financial Advisor Should Learn].
Currently, there are three ETFs that seek to replicate the performance of the S&P 500 Index, giving investors a number of different options. And while these three ETFs are largely similar and all exhibit a near perfect correlation with the underlying index, they aren’t quite identical; some structural nuances differentiate each of these products (we cover this topic in detail below):

|SPY||SPDR S&P 500 ETF||Unit Investment Trust||0.09%||Not Available|
|IVV||iShares S&P 500 Index Fund||Exchange Traded Fund||0.07%||3 Platforms|
|VOO||Vanguard S&P 500 ETF||Exchange Traded Fund||0.05%||Vanguard|

Under The Hood: SPY vs. IVV vs. VOO
S&P 500 SPDR (SPY, A)
SPY is the oldest U.S.-listed ETF, having begun trading in 1993 as an innovation in the financial world. Since then SPY has become one of the largest and most-widely traded securities in the world; assets currently stand at about $105 billion and average daily trading volume exceeds 200 million shares. SPY is structured as a Unit Investment Trust (UIT), with State Street serving as the trustee. The UIT structure, very common among the earliest ETF products to hit the market, is somewhat restrictive–a feature that has both pros and cons [see also 5 Tips ETF Traders Must Know].
UITs must fully replicate their underlying index, and are restricted from lending out securities that make up their portfolio. For investors employing somewhat complex strategies that include options, these restrictions ensure that SPY will replicate the benchmark with near-perfect precision–reliability that investors utilizing derivatives demand. While all of the S&P 500 ETFs offer impressive liquidity, SPY also offers an incredibly-liquid options market [compare the open interests of SPY vs. IVV]. This further increases the appeal of SPY as a tool for investors looking to execute intra-day trades or those who maintain relatively short holding periods.
The trading volumes support this idea: nearly one third of SPY’s shares outstanding change hands every day; by comparison, IVV’s daily turnover is equivalent to only about 2% of shares outstanding. That implies that SPY, while certainly appropriate for buy-and-holders, is more widely used as a trading vehicle for more active traders [see also 17 ETFs For Day Traders].
Another unique feature of UITs relates to dividends. According to SPY’s prospectus, the ETF pays dividends four times annually, on the last business day of April, July, October, and January. Because SPY is a UIT, the fund cannot reinvest dividends paid by underlying holdings, but rather must hold them in cash until they are scheduled to be distributed to SPY shareholders. So if ExxonMobil, for example, pays a dividend on February 1, SPY would be required to keep that amount in cash until the end of April.
IVV, like most other ETFs, utilizes an open-end structure that provides more flexibility to the portfolio manager. Though it generally replicates the underlying index very closely, IVV is permitted to use derivatives, portfolio sampling strategies, and lend out portfolio securities to generate additional income. Perhaps most importantly, the open-end structure allows for the immediate reinvestment of dividends, potentially resulting in enhanced returns during bull markets. Whereas SPY is required to keep dividends paid out in cash, IVV has the ability to invest distributions back into the components of the S&P 500 until it is scheduled to distribute them to IVV shareholders [see also Monthly Dividend ETFdb Portfolio].
The impact of this feature usually isn’t enormous, but it can contribute to slight return differentials between the two funds. Between the bear market lows in March 2009 (3/9/2009) and the end of that year, for example, SPY gained about 67.4%. IVV was up a slightly more impressive 67.7% during that same period. There are, of course, two sides to this coin. Reinvestment of dividends can adversely impact fund performance when markets are sinking. And indeed, during the equity market plunge of late 2008 and early 2009, SPY performed slightly better than IVV.
The most recent addition to the S&P 500 ETF space came relatively recently, as Vanguard rolled out a suite of ETFs linked to popular S&P 500 indexes. Vanguard was a pioneer in S&P 500 indexing, launching an indexed mutual fund seeking to replicate this benchmark in 1976. VOO maintains another unique structure that differentiates it from both IVV and SPY. Vanguard maintains a patent that allows it to offer ETFs as share class within larger index funds that also offer retail and institutional share classes.
There are some potential advantages to the share class structure of the Vanguard S&P 500 ETF. Although VOO is only a fraction the size of IVV and SPY, the total pool of assets across all share classes of the Vanguard product is about $94 billion. That allows VOO to offer the lowest expense ratio of the group, charging just five basis points.
While all ETFs have the ability to offer investors enhanced tax efficiency through the in-kind redemption process, VOO’s structure may offer additional tax benefits. In response to redemption requests from other classes of shareholders, Vanguard has the option to sell off high cost-basis securities, generating a capital loss in the process that can be used to offset any taxable gains. Of course redemptions of non-ETF share classes could also result in a taxable gain, but given the massive size of the S&P 500 fund such an event is unlikely unless a wave of redemptions were to occur [see Total Cost Of ETF Investing].
While the three ETFs linked to the S&P 500 will generally deliver nearly identical exposure, they aren’t quite identical thanks to some structural nuances. Each of the three ETFs offering exposure to the S&P 500 have potential advantages, ranging from cost and tax efficiencies to near-perfect precision and reliability to enhanced flexibility that can boost returns. Different funds will be more appropriate for different investors; the lesson, as always, is to take a good look under the hood and do your homework before establishing a position [for daily ETF news and analysis, sign up for our free ETF newsletter].
