A Most Curious Contest: VOO vs. SPY

Observe, if you will, a spectacle most common in the markets – a contest not of merit, but of minuscule distinctions! Two champions enter the arena, both claiming to offer a share in the prosperity of these five hundred prominent American enterprises, known collectively as the S&P 500 (^GSPC 0.06%). These are the Vanguard S&P 500 ETF (VOO 0.08%) and the SPDR S&P 500 ETF (SPY 0.03%).

At first glance, they appear as identical twins, each mirroring the other’s performance with uncanny precision. Both, it is said, track the very same index, possess liquidity enough to satisfy a king’s ransom, and boast fees so low as to scarcely offend the most frugal of investors. One might be forgiven for believing them to be but two faces of the same coin. And yet, as any seasoned observer of human folly knows, it is often the smallest of details that reveal the true character of a thing.

Thus, we must delve beneath the surface, as a physician examines a patient, to discern what truly separates these contenders. For while they may seem alike, a discerning eye will detect subtle differences, and over the long march of time, these differences, however slight, may prove decisive.

The Matter of Composition, and a Most Peculiar Inclination

Let us not waste our breath discussing the precise holdings of these funds, for they are, in essence, reflections of the same grand portfolio. Though it is worth noting, with a touch of wry amusement, that this index, like so many things in life, appears to be unduly captivated by a handful of technological behemoths – Nvidia, Microsoft, Apple, Amazon, Alphabet, Meta Platforms, and Tesla, they are called. A most curious inclination, is it not, to place so much faith in so few?

The true contest, therefore, lies not in what is held, but in how it is held. The cost of ownership, encompassing both the expense ratio and the inevitable trading spreads, will ultimately determine which fund proves the more advantageous.

Furthermore, a curious structural distinction presents itself. The Vanguard fund operates as a traditional, open-ended exchange-traded fund, while the SPDR fund is constructed as a Unit Investment Trust. This seemingly arcane detail carries a consequence: the SPDR fund, bound by its structure, cannot immediately reinvest its dividends, and, rather like a miser guarding his coins, keeps a small hoard of cash on hand. Over the years, this habit, though seemingly innocuous, may subtly diminish its performance.

However, let us not dismiss the SPDR fund entirely. It possesses a liquidity advantage, boasting a trading volume some nine times greater than that of its Vanguard counterpart. This, for the frequent trader, may translate into lower trading spreads – a boon, though perhaps a fleeting one, for those who treat the market as a game of chance.

The Triumph of Frugality: A Lesson in Prudence

The SPDR S&P 500 ETF levies an expense ratio of 0.0945%. The Vanguard S&P 500 ETF, in a display of commendable frugality, charges but 0.03%.

This difference, though seemingly small, is not to be dismissed. In the realm of vast sums and extended timelines, it compounds, accumulating over years and decades to create a meaningful advantage. It is a testament to the power of prudence, a reminder that even the smallest of savings, diligently applied, can yield substantial rewards.

For the nimble trader, the SPDR fund may still hold some appeal. If one can consistently capture even a sliver of savings on each trade, it may offset the expense ratio disadvantage. But let us not mistake activity for wisdom. The more one trades, the more likely it is that this SPDR fund will prove the better choice, but also the more likely it is that one is simply chasing shadows.

For the vast majority of long-term investors, however, the Vanguard S&P 500 ETF emerges as the superior choice. It offers the same exposure to the American stock market as the SPDR fund, but does so with lower fees. This simple advantage allows investors to retain a greater portion of their wealth, a principle as timeless as it is true.
