17 S&P 500 Stocks Hit 52-Week Highs On Thursday
A narrow list of market leaders includes industrial giants and high-growth names with very different fundamentals.
On a day when the S&P 500 has returned just +0.6% over the last month, 17 of its components are trading at their 52-week highs. The list is led by size, with JPMorgan Chase (JPM) and its market value of about $950.4 billion at the top.
But the real story is in the clusters, with Rail Transportation and Pharmaceuticals showing notable strength. This raises a critical question: what price is being paid for these pockets of leadership? The names below show a wide range of answers.

The table below shows the 10 largest of the 17 names, sorted by market capitalization, with returns over four windows:
| Tickers | Market Cap |
1D % Chg |
1W % Chg |
1M % Chg |
1Y % Chg |
|---|---|---|---|---|---|
| JPM | $950.4 Bil | 0.5% | 2.0% | 5.2% | 22.4% |
| MRK | $322.5 Bil | 2.4% | 2.2% | 9.1% | 65.2% |
| UNP | $180.5 Bil | 4.0% | 1.6% | 17.7% | 35.8% |

| NSC | $78.2 Bil | 5.3% | 3.1% | 14.9% | 26.7% |
Which businesses show the price of strength?
Consider the contrast between two names on the list. Union Pacific (UNP) has gained 17.7% over the last month and trades at 25.0 times trailing earnings. Its revenue grew 1.9% over the last twelve months, supported by an operating margin of 40.2%.
Then there is Welltower (WELL), a Health Care REIT. It trades at 122.8 times trailing earnings. That valuation is paired with revenue growth of 37.7% over the last twelve months, but an operating margin of 4.6%.
A new high is a price, not a verdict.
A list of stocks at their strongest price of the last year is a useful screen for leadership. Strength often persists, and these are companies the market is rewarding for one reason or another.
But a price is not a business. The disciplined next step is to ask whether the underlying operations, from revenue growth to margins, can support the new valuation. The work begins, it does not end, at the 52-week high.
A new high tells you what the market already believes. The harder question is which of these runs management itself is underwriting. Our Guidance Momentum screen tracks exactly that: stocks where the company raised its own forward numbers.
One more pattern worth noticing: 7 of the 17 names are Industrials stocks. When a whole group is making new highs together, a U.S. transportation ETF like IYT is one way to own the group’s strength without betting on which single name leads it from here.
