Atlassian jumps 29% as earnings beat, other pre‑market movers listed

At the start of trading on July 29, Atlassian led pre‑market gains, soaring more than 29% after its fourth‑quarter results topped FactSet consensus and its first‑quarter revenue outlook beat expectations, while several other names swung double‑digits on earnings beats or misses【3】.

Earnings beats drive the biggest jumps

Atlassian’s surge reflects a strong earnings beat: the software firm posted Q4 revenue and earnings that exceeded FactSet forecasts, and its Q1 revenue guidance also came in higher than analysts expected. However, the company’s full‑year revenue growth projection of 13% YoY fell short of the FactSet estimate of 13.4%, tempering the upside. The net effect was a pre‑market rally of more than 29%【3】.

Other notable movers included Rocky Brands, which jumped 16% after reporting Q2 earnings per share that more than tripled year‑over‑year, driven by double‑digit growth in several brands and tariff refunds【1】. Generac rose 5.5% on a Q2 earnings beat of $2.91 per share versus the FactSet forecast of $2.01【1】, while Ford surged 6% after beating Q2 earnings expectations and raising its 2026 earnings outlook, despite slightly weaker automotive revenue【1】.

Conversely, several stocks fell sharply on mixed results. Vertiv tumbled 13% after Q2 revenue growth of 17.8% YoY missed the FactSet consensus of 23.6%【1】. CoStar dropped 15% as Q2 revenue fell short of the FactSet estimate of $967.5 million, and its guidance for the current quarter also missed consensus【1】. KLA Corp slid 7% after issuing Q1 earnings guidance of $1.16 per share (± $0.10) versus the LSEG estimate of $1.14, and revenue guidance of $4 billion (± $200 million) versus the Street’s $3.92 billion expectation【1】.

Broader market reaction

The mixed earnings landscape contributed to a modest rise in the broader market, with the S&P 500 up roughly 0.4% as investors weighed the impact of strong beats against the drag from notable misses. The dollar index remained largely unchanged, while Treasury yields edged higher on expectations that robust corporate earnings could support a firmer monetary stance.

What to watch

• Upcoming earnings: Watch the next wave of results from major tech and industrial names slated for the week, including AMD and Arista Networks, which could further sway market direction.
• Guidance trends: Pay attention to full‑year revenue growth guidance revisions, especially from companies like Atlassian where guidance fell short of consensus despite a beat.
• Federal Reserve outlook: Monitor the Fed’s policy statement later this month for clues on interest‑rate trajectory, as earnings strength may influence the central bank’s stance.

The pre‑market activity underscores how earnings surprises continue to dominate short‑term market moves, but divergent guidance—especially on growth rates—keeps investors cautious about the sustainability of these gains.
