Chart of the Day
Here is the one-year chart of Rubrik (RBRK) as of December 10, 2025, when the stock was at $91.
Rubrik (RBRK) is a new cybersecurity company with a mission centered on protecting global data. The company focuses on making guardrails for AI agents, which have access to all sorts of company data. Rubrik also provides recovery from cyberattacks.
Rubrik delivered excellent results last quarter. Analysts expected a loss of $0.17 a share, but it delivered a profit of $0.10. Revenue growth was expected to be 35% and the company delivered 48%.
This stock fits the mold David Sharek, Founder of School of Hard Stocks, is looking for. However, he wonders if competition will be able to accomplish data cybersecurity as well. He just did the Palo Alto Networks (PANW) report and they claim to be the furthest ahead in terms of AI security. And CrowdStrike (CRWD) is a top cybersecurity company.
RBRK is on the radar for our Growth Portfolio.
