Key Highlights

  • Amdocs (NASDAQ:DOX) was reported 30% lower after trimming its fiscal 2027 Revenue view, making it the deepest decline among the five losers on November 4, 2026.
  • FIS (NYSE:FIS) lost 24% after a reduced full-year Earnings outlook and a CFO departure, according to published coverage.
  • Zillow (NASDAQ:ZG) slipped about 15% after hours, as published coverage said both Earnings Per Share and revenue came in under expectations.
  • Snap (NYSE:SNAP) dropped 8.6% to 11.5% after hours following a revenue shortfall of USD 10 million, with a user count of 495 million reported alongside.

Amdocs (NASDAQ:DOX) Slides Roughly 30% After Trimming Its Revenue Band

Amdocs stands as the largest drop on this list, with shares reported lower by roughly 30% on November 4, 2026. Coverage connected the slide to a fiscal 2027 projection calling for revenue to fall 14% to 18%, alongside a legal fight involving T-Mobile. Because revenue guidance sets the foundation for profit forecasts, a shrinking band usually leads analysts to reduce estimates, and investors may pay less per dollar of expected earnings. Reporting offered no scale, schedule or probable verdict for the T-Mobile matter, leaving its contribution to the selloff unmeasurable. The 30% number relies on published summaries rather than a company release, so benchmark it against the intraday quote and the filing before repeating it. Amdocs (NASDAQ:DOX) faces the possibility that the revised band gets cut again should Demand soften or the dispute change contract terms.

FIS (NYSE:FIS) Falls 24% on a Guidance Reset, CFO Departure and Downgrade

FIS shares lost 24% on November 4, 2026, according to published coverage, once its full-year earnings per share outlook was lowered, with the range now set at USD 5.82 to USD 5.89 versus the earlier USD 6.15 to USD 6.24. Reporting also says CFO James Kehoe will step away, and that JPMorgan cut its rating on the shares. The selloff was characterized as nearly a record one-day fall for an S&P 500 component. Three developments landed in a single session, so the piece of the decline attributable to each cannot be separated. A guidance cut shrinks the earnings base investors rely on for valuation. The outlook midpoint shifts from roughly USD 6.20 to about USD 5.86, a decline of around 5.5%, which is simple arithmetic on two published figures. FIS (NYSE:FIS) has no named successor for its finance chief yet, and further cuts or a drawn-out handover remain live risks.

Zillow (NASDAQ:ZG) Drops Near 15% in Extended Trading After Missing on Profit and Sales

Zillow's stock slid close to 15% during after-hours trade on November 4, 2026, with published coverage describing misses on both earnings per share and revenue. A double miss signals that profit and sales both landed beneath what market prices had assumed. The coverage available here omits the precise EPS and revenue numbers, so no figure is attached to either gap. Equity values hinge on projected earnings, so a weaker profit and sales run-rate may lead analysts to lower forward estimates too. Zillow's fortunes are tied to housing transactions, so the same shortfall could be read as an indicator of real estate demand. After-hours Volume is light, which makes the 15% a first reaction rather than a closed price. The chief hazard is that this miss signals a longer slowdown, and the company release should reveal whether Zillow (NASDAQ:ZG) revised its guidance.

Snap (NYSE:SNAP) Slips 8.6% to 11.5% After Hours on a USD 10 Million Revenue Miss

Snap posted revenue of USD 1.72 billion, which came in USD 10 million below forecasts, while its user count of 495 million disappointed shareholders. Published market data shows the shares sliding between 8.6% and 11.5% during extended trading on November 4, 2026. Those quotes moved around as the evening progressed, so the band captures that drift instead of a closing level. Top-line sales are the clearest gauge of growth, and a USD 10 million gap indicates the Business is trailing its own projections. User numbers serve as a second barometer, since audience size influences what investors will pay for future sales. Because the report landed after the bell, first trades can surge and fade on sparse volume. The core danger for Snap (NYSE:SNAP) is that the miss marks a slowdown in both users and revenue, a trend that could weigh on the stock well beyond one session.

Datadog (NASDAQ:DDOG) Slides 14% Despite 35% Revenue Growth on a Flat Outlook

Datadog shares declined 14% on November 4, 2026, although revenue advanced 35% to USD 1.20 billion for the period. The trigger was a fourth-quarter range of USD 1.19 billion to USD 1.20 billion, nearly unchanged from the present period. Stock prices price in future growth, so a near-term range implying minimal expansion can compress valuation even when the latest period looks robust. A comparison of published figures shows the top of the guided range equals the current period's revenue, meaning the upper end suggests roughly zero sequential change. Software firms are generally assessed on forward guidance, so projections that assumed continued acceleration would need to be lowered. The central risk for Datadog (NASDAQ:DDOG) is that the outlook turns out more conservative than reported growth suggests, with any upside requiring a beat against its own band. A broader sector retreat could deepen the drop regardless of company results.

Where Things Stand

Amdocs (NASDAQ:DOX) topped the decline table, with coverage placing it near 30% lower on November 4, 2026. Each of the five names reacted to a results or outlook development that day. Amdocs trimmed its fiscal 2027 forecast, FIS cut earnings guidance and faces a finance chief exit, Zillow and Snap undershot expectations, and Datadog pointed to a flat fourth quarter. FIS (NYSE:FIS) also absorbed a JPMorgan downgrade. Datadog (NASDAQ:DDOG) declined despite 35% revenue growth, illustrating how heavily markets weigh forward guidance. Zillow (NASDAQ:ZG) and Snap traded after the bell, so their numbers could shift once the regular session opens. Verify each company release or filing before repeating these figures, as most are reported rather than confirmed.
