  • Arch Capital (NASDAQ:ACGL) is quoted at USD 109.31, higher by 2.77%, on 2.15 million shares (relative Volume 1.00), with a USD 37.30 billion market cap, a 52-week high of USD 110.26, a P/E of 8.93 and EPS of USD 12.24, based on the 52-week high screen captured November 4, 2026.

  • Addus HomeCare (NASDAQ:ADUS) trades at USD 125.75, up 0.17%, on 508,400 shares (relative volume 2.34), with a USD 2.35 billion market cap, a 52-week high of USD 127.06, a P/E of 22.06 and EPS of USD 5.70 on the 52-week high screen, captured November 4, 2026.

1. AerCap (NYSE:AER)

On the all-time high screen, AerCap (NYSE:AER) shows USD 163.34, up 3.04%, on 1.37 million shares (relative volume 1.04), with a USD 25.22 billion market cap, a P/E of 8.37, EPS of USD 19.51 and a 0.93% dividend yield, captured November 4, 2026. A peak reveals the price level, not the cheapness of the shares, so the results and valuation deserve attention. Third quarter 2026 results on October 28, 2026 reported adjusted EPS of USD 6.56 versus a USD 4.56 consensus, according to published coverage, with Revenue near USD 1.97 billion, up 3.8% but below a USD 2.16 billion estimate. Full-year adjusted EPS guidance rose to about USD 20.70, leaving out fourth quarter gains on sale. AerCap bought back roughly USD 783 million of stock during the quarter, leaving USD 913 million under a USD 1 billion authorization. The concern is that the beat depends on one coverage source, revenue missed, and a record after an 11.9% rally leaves less cushion for disappointment.

2. Allegion (NYSE:ALLE)

On the all-time high screen, Allegion (NYSE:ALLE) appears at USD 191.73, up 2.84%, on 1.21 million shares (relative volume 0.85), with a USD 16.17 billion market cap, a P/E of 23.86, EPS of USD 8.04 and a 1.16% dividend yield, captured November 4, 2026. Shares at highs meet no overhead Supply from earlier buyers, but they also have thinner room for error if results weaken, which is the case for ALLE. Management lifted its 2026 adjusted EPS outlook to USD 9.05 to USD 9.10 from USD 8.85 to USD 9.00, and its revenue growth outlook to 9.5% to 10.5%. Using the USD 9.075 midpoint, USD 191.73 equals about 21 times 2026 adjusted EPS by simple math. The concern is that the stock trades near 21 times outlook Earnings after a 7.6% rise, and a record can lose steam if growth slows.

3. Arch Capital (NASDAQ:ACGL)

Arch Capital (NASDAQ:ACGL) is quoted at USD 109.31, USD 0.95 below its 52-week high of USD 110.26, while premiums declined 3.0%. Shares near highs meet no resistance from earlier holders, yet there is less buffer for a soft report, which applies to ACGL. Third quarter results on October 27, 2026 showed Net Income available to common of USD 1,025 million, or USD 3.00 per diluted share, and after-tax Operating Income of USD 910 million, or USD 2.67 per share, compared with USD 2.77 a year earlier. Net premiums written dropped 3.0% to USD 3,845 million, and the combined ratio rose to 82.5% from 79.8%. The concern is that premium volume and per-share operating income declined while the shares rose, and a rising combined ratio shrinks Underwriting margins.

4. Arthur J. Gallagher (NYSE:AJG)

Arthur J. Gallagher (NYSE:AJG) is at USD 278.89, USD 2.64 under its 52-week high of USD 281.53, with revenue up 18%. AJG appears on the list because it sits at or near the highest price in its history or its one year range, a momentum signal. Published market data placed the one year low at USD 190.75, so USD 278.89 sits about 46% above it, by simple math. The company acquired The Mund Group on October 21, 2026 and a Melbourne firm on October 19, 2026, while Pen Underwriting acquired Ornella Underwriting of Ireland on October 7, 2026; terms were not disclosed. The concern is a P/E of 42.60 after a 46% climb from the low, undisclosed deal terms, and growth figures drawn from a single source.

5. Addus HomeCare (NASDAQ:ADUS)

Addus HomeCare (NASDAQ:ADUS) trades at USD 125.75, USD 1.31 under its 52-week high of USD 127.06, after agreeing to a USD 275.0 million transaction. Peaks reveal where a price stands, not whether it is inexpensive, so the release and valuation need a look. Adjusted EPS came in at USD 1.83, up 17.3% from USD 1.56, and adjusted EBITDA reached USD 51.2 million, up 13.5%. The release offered no fresh guidance. The worry is that AccentCare still awaits regulatory clearance, no guidance was offered, and a downgrade from an analyst came before the report.

Where Things Stand

Only partly. AJG reported revenue growth of 18% from a single source, ALLE grew revenue 9.6% and raised its outlook, ADUS lifted net service revenues 7.0%, AER grew revenue 3.8% but missed an estimate, and ACGL saw net premiums written slip 3.0%, so growth is uneven behind these highs. Highs often rest on sound results, yet screens also pick up one-time boosts such as special dividends, Tariff refunds and recent listings. Separating what can repeat from a single event is the key check. Readers comparing these names should keep the screen date and the filing date apart, since the two can fall on different days.
