Inside SPY Stock’s $744 Moment: Inflation, AI, and the Quiet Rally Nobody Can Quite Explain

There’s something strange about SPY. Although it is, in many respects, Wall Street’s most dull ticker, practically every significant event in the US markets eventually appears on its chart. SPY is currently trading at $743.57 on Thursday, May 14, 2026, effectively at a 52-week high of $743.91. At 44.2 million shares, volume has remained consistent and is just somewhat below than the daily average of 49.38 million.

After rising from a low of $575.60, the 52-week range depicts a market that has, for some reason, refused to give back its gains for more than a year. The fund is up 8.71% so far this year. It has increased by over 27% in the past 12 months. These are impressive figures for the most traded ETF in the world.

The fund is now old enough to feel less like an investment product and more like a component of the financial infrastructure. On January 22, 1993, State Street introduced SPY, the first exchange-traded fund (ETF) to be listed on a U.S. exchange. It had a straightforward structure. If you purchase a share of SPY, you will effectively own a small, proportionate fraction of each of the 500 S&P 500 firms. At only 0.09%, the fund’s expense ratio is essentially meaningless.

It has produced a cumulative inflation-adjusted return of more than 1,100% over its lifespan, with an annualized total return of roughly 10.59%, or roughly 7.83% adjusted for inflation. Over several cycles, the long-term discipline of simply purchasing the index and waiting has beaten the most actively managed funds. That concept wasn’t created by SPY, but it was made possible by it.

On the surface, the current rally is being driven by the same factor that has propelled every move in the U.S. market during the previous two years. Megacap technology. Currently, SPY’s top 10 holdings account for about 37% of the whole portfolio. The index and SPY move mechanically when Microsoft, Apple, Amazon, Alphabet, Meta, and Nvidia all beat earnings in the same time frame. With almost 80% of S&P 500 firms exceeding projections, Q1 2026 earnings season has been generally positive.

JPMorgan increased its estimate of S&P 500 EPS for 2026 to $330. Apple reported record March-quarter revenue of $111.2 billion combined with a fresh $100 billion buyback, Google Cloud rose 63%, Amazon’s AWS came in at 28%, and Alphabet surged roughly 6% in April on a blowout quarter. As a result, the S&P 500 had its best month since 2020, and SPY continued to push for new highs into May.

What’s going on beneath the motion is what complicates things. Due mostly to a 21% increase in gas costs related to the current U.S.-Iran war, the March CPI came in hot at 3.3% year over year. For weeks, the price of a barrel of Brent crude has remained between $103 and $105. The inflation figure on Tuesday, which was even hotter than anticipated at 3.8%, caused SPY to momentarily decline. Then, on Wednesday, it recovered, with the AI trade absorbing the negative news and boosting the market as a whole.

As this develops, it seems as though the market has decided to see nearly everything in an optimistic light. Extensions of the Iran ceasefire are seen as positive news. Inflation is priced as temporary. The Fed’s decision to keep rates between 3.50 and 3.75% is seen as proof that the soft landing is genuine. None of those interpretations are inherently incorrect. However, they all rely on a series of events continuing to go well for a few more quarters.

Compared to most of his colleagues, Goldman Sachs strategist Tony Pasquariello has been more cautious, pointing out that the S&P 500’s RSI is close to 70, which typically indicates an overbought situation. Despite the index reaching new highs, speculative purchasing impetus has been waning. It was estimated that CTAs, or systematic trend-following funds, were purchasing about $45 billion worth of stocks in a recent week.

However, this flow is by definition a momentum effect rather than a fundamental one. Through late April, six weeks in a row of equity fund inflows created ongoing purchasing pressure on broad index funds such as SPY. The identical physics that raised the index will operate in the other direction when that flow ultimately reverses, as it always does.

Naturally, the cost issue is the longer-term comparison that keeps coming up. Vanguard’s VOO tracks the same S&P 500 index and charges 0.03%, which is about one-third of SPY’s expense ratio. The differential accumulates significantly over decades for a long-term holder.

However, SPY continues to have the world’s deepest options market, the tightest bid-ask spreads, and the highest liquidity of any ETF, making it the clear choice for large-scale institutional clients, active traders, and hedgers. The distinction between VOO for buy-and-hold and SPY for trading has grown so well-known that it is now practically considered a piece of investment folklore.
