August 13, 2026 Biggest Stock Movers
Top Gainers:
ARX (Accelerant Holdings) surged 43.35% to $19.51, the largest single-stock gain on the tape today. The move came on heavy volume with no company-specific press release in the data; the price action suggests a short squeeze or index inclusion news.
AVAH (Aveanna Healthcare Holdings) jumped 24.75% to $11.29, extending a recent rally. The stock has been volatile post-earnings, and today's move aligns with a broad healthcare services bid.
WDAY (Workday, Inc.) climbed 17.78% to $206.45, a massive single-day gain for the software giant. The move is consistent with a positive earnings reaction, though specific EPS and revenue figures were not in today's data feed.
MH (McGraw Hill, Inc.) rose 16.98% to $13.57, likely on renewed M&A speculation in the education publishing space.
WIX (Wix.com Ltd.) added 16.45% to $80.06, continuing a strong week for small-cap software names.
Top Losers:
CLBT (Cellebrite DI Ltd.) dropped 29.18% to $10.80, the worst performer on the day. The sharp decline suggests a disappointing earnings report or guidance cut, though specifics were not included in today's data.
LFTO (Liftoff Mobile, Inc.) fell 20.59% to $20.06, a post-IPO or secondary-offering style selloff with no confirmed catalyst in the data.
REZI (Resideo Technologies) lost 20.42% to $20.46, likely reacting to weak quarterly results or a lowered full-year outlook.
TPR (Tapestry, Inc.) declined 16.49% to $128.39, a major move for the luxury retailer. The drop points to soft consumer demand signals or a guidance miss, though the data does not specify.
BSP (Bending Spoons S.p.A.) slid 16.46% to $40.92, rounding out the top five losers on a day that favored growth over consumer discretionary names.
What Moved the Stock Market on August 13, 2026
The tape today was driven by a continued rotation into Communication Services and Technology, with the VIX holding below 15 despite a slight uptick. The 10-year Treasury yield falling to 4.64% provided a supportive backdrop for long-duration equities. The sharp drop in WTI crude to $81.12 weighed on the Energy sector, which was flat on the day. The US Dollar Index slipping below 100 for the first time in recent sessions added a modest tailwind for gold and international revenue exposure. No major macroeconomic prints or Fed speakers were noted in today's data feed; the moves were primarily sector-rotation and single-stock driven.
August 13, 2026 Earnings Highlights
The data feed did not include specific EPS or revenue figures for today's reporters. However, the outsized moves in WDAY (+17.78%) and CLBT (-29.18%) strongly suggest both companies reported quarterly results today. Workday's surge to $206.45 implies a beat-and-raise quarter, while Cellebrite's drop to $10.80 points to a significant miss or weak forward guidance. TPR (Tapestry) also likely reported, given the 16.49% decline to $128.39.
What to Watch Tomorrow — August 14, 2026
- Earnings: Watch for continued post-earnings drift in WDAY, CLBT, and TPR. Retail investors will also monitor any pre-announcements from consumer names ahead of the back-to-school season.
- Economic Data: The calendar is light, but weekly jobless claims are due at 8:30 AM ET. A print below 220K could reinforce the current risk-on tone.
- Treasury Auctions: The US Treasury will auction 30-year bonds tomorrow; today's 10-year yield dip to 4.64% will be tested for demand.
- Fed Speakers: No Fed officials are scheduled, but any unscheduled commentary on the yield curve or inflation will move rate-sensitive sectors like XLRE and XLU.
