Why Are Stocks So Resilient? Earnings!

The Big Question

Since early April, U.S. stocks have rallied sharply despite an ongoing war, rising inflation fueled by soaring oil prices (near $100/barrel), higher bond yields (up 0.6 to 0.7 percentage points), and frothy valuations (21 times projected earnings vs. a historical average of 17 times for the S&P 500 Index).

That combination seems like a clear negative for markets. So why are equities still rising? The answer is a combination of how today’s stock market is constructed, strong earnings momentum, and structural changes in the economy.

Market Composition

The S&P 500 today looks very different than it did in the past. Technology is now one of the largest sectors, with a small number of very large companies driving a significant share of returns. These companies have higher-than-average profit margins and are less tied to physical input costs such as oil prices.

The chart below shows just how complete the transition has been. In 1980, the Energy sector made up roughly 28% of the S&P 500—Exxon was the largest company in America and oil supermajors dominated the index.

Today, Energy is just ~3% while Information Technology has risen from ~4% to ~32%. The two sectors crossed around 1995 and have diverged consistently since. Including Communication Services (Alphabet, Meta, Netflix—reclassified out of IT in 2018), the broader “tech complex” is closer to 40% of the index. Adding Amazon, a Consumer Discretionary stock, would raise the number even higher. This composition shift explains why the market is structurally less sensitive to oil shocks than in prior cycles: the index’s largest constituents now sell software, advertising, and cloud services with minimal physical input costs.

It also helps explain why higher valuations may be justified. An index dominated by growth technology companies with fat profit margins should demand a higher price than one dominated by slower growing energy, industrial, or consumer staples stocks. NVIDIA’s growth trajectory has more potential than Exxon’s.

Strong Earnings are Doing Most of The Work

At the most basic level, markets follow earnings—and earnings continue to be stronger than expected, especially within the tech sector.

First quarter S&P 500 earnings growth is coming in at 28% year over year so far, with 83% of companies beating analysts’ expectations. Technology and Communication Services are leading the way with astounding 50%+ growth driven largely by the AI investment cycle. The "Magnificent 7" (Mag7) continue to outgrow the other 493 S&P 500 companies by a wide margin.

Higher valuations look more reasonable when contextualized with the fact the underlying businesses have been continuing to beat on the bottom line (earnings) and the top line (revenue) [Figure 2]. Stocks aren’t rising just because investors are paying more—companies are earning more. In fact, the Forward P/E has declined slightly from the peak as earnings growth has outpaced market gains.

The Consumer Is Less Vulnerable to Oil Shocks

Market composition and earnings are a big part of the market’s resilience, but not the only part. The consumers who fuel growth in the US are also less sensitive to oil prices.

Although the U.S. is now a net exporter of petroleum products and the economy is less exposed to oil price spikes than in the past, gas prices are still determined globally, and consumers still feel the impact. Just not as much as they used to.

The chart below shows how energy spending has changed for U.S. households. Energy goods and services as a share of disposable personal income peaked near 8% in 1981 and has fallen to 3.4% today. Even the 2022 oil price spike pushed the ratio only briefly to 4.7% before retracing. The structural decline reflects efficiency gains across the economy and rising real incomes/net worths, diluting the share of the household wallet exposed to energy. A given dollar move in crude now consumes a meaningfully smaller share of consumer budgets than it did in prior cycles.

It is also true that not all consumers are feeling the same pressure. Higher income households now drive a greater share of consumer spending, and they are less impacted by high gas prices.

According to Federal Reserve data, from Q4 2019 through Q4 2025, the top 1% of U.S. households added roughly $22.5 trillion in net worth—nearly 10x more in absolute dollars than the entire bottom 50% combined (~$2.4T), despite the bottom half representing fifty times more households. The marginal consumer driving discretionary spending therefore has substantial accumulated wealth to draw on, which dampens the sensitivity of aggregate consumption to short-term shocks like gas-price spikes.

Rational Exuberance?

Markets may seem disconnected from headlines or how the economy feels to an average consumer, but the stock market reflects deeper changes in how the economy and stock market are composed today. Both the stock market and consumer are less vulnerable to oil shocks, and the large technology companies dominating the major stock market indices are experiencing tremendous profit growth that is reflected in investors’ willingness to pay up for future growth.

There are risks to this market rally. Index concentration makes the market vulnerable to anything that disrupts the AI investment cycle. Some tech companies themselves may be threatened by competition from AI that could make certain technologies obsolete. And inflation, if it persists, could result in higher bond yields that will be a headwind to growth and investment. But this rally isn’t driven by the “irrational exuberance” Alan Greenspan warned of in 1996. Earnings, the economy, and the consumer are telling a different story this time.
