S&P 500 Gains 22% as Earnings Growth Outpaces Prices

The S&P 500 rose 22% over the trailing 12 months ending in August, while price-to-earnings multiples contracted, according to Barron's. Corporate earnings growth outpaced price appreciation during the window, leaving the benchmark cheaper than it was a year ago.

The pattern marks a shift from the prior cycle, when multiple expansion — investors paying more for each dollar of earnings — carried the index. Now profit growth is doing the work, a dynamic Argus Research expects to continue. The firm's 2026 target for the S&P 500 sits at 7,400, up about 8 percent from the 2025 year-end close.

Trane Technologies, an S&P 500 constituent in the Industrials sector, illustrates the trend. Argus maintained a bullish rating on the HVAC maker in May, raising its price target and earnings estimate as profit growth outpaced the share gain. Analysts' average price target on Trane stands at $525.28, versus a current price near $482, according to Yahoo Finance data. Argus also named Trane a top stock pick for 2026, citing its double-digit dividend growth over the past five years.

For investors, rising prices with falling multiples creates a more attractive entry point than a rally built on valuation alone. If earnings keep outpacing prices, the index can extend gains without becoming overvalued, and the risk of a sharp correction recedes as long as profit growth holds. The next test comes with the third-quarter earnings season, when companies must deliver the profit growth that has underpinned the advance.

Earnings Carry the Rally as Multiples Fall

The divergence between price and valuation is the defining feature of the current advance. When an index rises while its P/E falls, the earnings denominator is growing faster than the price numerator — a sign the rally rests on fundamentals rather than speculative flows. That contrasts with the 2024-2025 period, when a handful of large-cap technology names drove much of the index's gain through multiple expansion.

For value-oriented investors, the setup is more favorable than it appears. A market that has risen 22 percent but trades at a lower multiple offers a margin of safety that a purely valuation-driven rally would not. The compression also gives the index room to absorb higher interest rates or a modest earnings slowdown without triggering a sharp de-rating.

The earnings growth behind the move has been broad-based, with industrials and other cyclical sectors contributing alongside technology. Trane's trajectory is representative: profit growth has supported a rising share price even as its valuation has stayed in check, and analysts see further upside. The average price target of $525.28 implies roughly 9 percent upside from the current level, according to Yahoo Finance data.

Argus's 7,400 target for the S&P 500 implies the index can keep climbing even as multiples stay flat, provided earnings grow at the double-digit pace the firm projects. The firm expects earnings to rise 12 percent in 2026, after a 10 percent increase in 2025, with interest rates trending lower as the Federal Reserve continues to ease. Should earnings growth slow, the valuation cushion built over the past year gives the market room to absorb the disappointment without a sharp repricing.
