Let’s dig into the relative performance of Zscaler (NASDAQ:ZS) and its peers as we unravel the now-completed Q3 cybersecurity earnings season.

Cybersecurity continues to be one of the fastest-growing segments within software for good reason. Almost every company is slowly finding itself becoming a technology company and facing rising cybersecurity risks. Businesses are accelerating adoption of cloud-based software, moving data and applications into the cloud to save costs while improving performance. This migration has opened them to a multitude of new threats, like employees accessing data via their smartphone while on an open network, or logging into a web-based interface from a laptop in a new location.

The 9 cybersecurity stocks we track reported a satisfactory Q3. As a group, revenues beat analysts’ consensus estimates by 1% while next quarter’s revenue guidance was in line.

Amidst this news, share prices of the companies have had a rough stretch. On average, they are down 8.4% since the latest earnings results.

Market Update

In response to the Fed’s rate hikes in 2022 and 2023, inflation has been gradually trending down from its post-pandemic peak, trending closer to the Fed’s 2% target. Despite higher borrowing costs, the economy has avoided flashing recessionary signals. This is the much-desired soft landing that many investors hoped for. The recent rate cuts (0.5% in September and 0.25% in November 2024) have bolstered the stock market, making 2024 a strong year for equities. Donald Trump’s presidential win in November sparked additional market gains, sending indices to record highs in the days following his victory. However, debates continue over possible tariffs and corporate tax adjustments, raising questions about economic stability in 2025.
