Stock Market Today: October 23, 2026 — Tech Lag as Energy Leads

Robert Half Leads Top Gainers as Dow Drops More Than 1%

RHI closed at 45.87, up 21.74%, making it the day's top gainer. The staffing company's sharp rally came while the broader market retreated, with the Dow Jones ^DJI falling 1.23% to 52,215.16 and the S&P 500 ^GSPC down 0.52% to 7,623.68. RHI's move stands out as the largest single-name percentage gain on the tape, well ahead of GMAB at 9.47% and NTSK at 9.37%.

Tech and Communication Services Lead Sector Declines

Technology XLK fell 2.82% to lead sector losses, dragging the Nasdaq Composite ^IXIC down 0.21% to 25,955.34. Communication Services XLC dropped 3.18%, the steepest sector decline of the day, while Industrials XLI fell 2.19% and Consumer Discretionary XLY lost 2.10%. The sector rotation left only Energy, Utilities, Consumer Staples, Real Estate, and Health Care in positive territory.

Bloom Energy Leads Top Losers with Double-Digit Drop

BE closed at 193.30, down 11.24%, headlining the day's top losers. LKQ fell 22.47% to 17.42, RGC dropped 21.81% to 7.67, CORT lost 20.13% to 85.86, and TNGX declined 16.43% to 23.34. The breadth of double-digit percentage losses across small-cap names contrasts with the more measured declines in large-cap indices.

TL;DR: The Dow fell 1.23% to 52,215.16, the S&P 500 slipped 0.52% to 7,623.68, and the Nasdaq edged down 0.21% to 25,955.34 as energy led sector gains; RHI was the top gainer at +21.74% to 45.87 while BE led losers at -11.24%.

THE THREE STORIES THAT MOVED SMALL CAPS

RHI Leads Gainers with 21.74% Rally

RHI closed at 45.87, up 21.74%, the largest single-day percentage gain in today's data. The Robert Hill staffing name outperformed all other top gainers, including GMAB at 9.47%, NTSK at 9.37%, VG at 9.29%, and CART at 9.21%. No volume figure is included in today's data, so the move is quantified by price and percentage alone.

BE Leads Losers with 11.24% Decline

BE fell 11.24% to close at 193.30, the largest loss among today's top losers. The Bloom Energy drop trailed LKQ at -22.47% to 17.42, RGC at -21.81% to 7.67, CORT at -20.13% to 85.86, and TNGX at -16.43% to 23.34. Five names in the top losers list posted double-digit percentage declines, signaling concentrated small-cap selling pressure.

LKQ Posts Largest Percentage Loss at -22.47%

LKQ closed at 17.42, down 22.47%, the steepest percentage decline in today's top losers. The move exceeded RGC at -21.81% and CORT at -20.13%. Like the other small-cap stories above, no volume or catalyst data is provided, so the factual record is the price action itself.

ONE ACTIONABLE TAKEAWAY

Today's tape showed a clear split: defensive sectors rose while technology and communication services fell, and small-cap names posted outsized gains and losses on both ends. A scanner tuned to high relative volume and percentage movers would have caught RHI on the upside and LKQ on the downside before the close.
