Rubrik Surges 5.97% on Google Cloud Pact but Ranks 407th in 280M Volume

On October 8, 2025, Rubrik (RBRK) closed at a 5.97% gain, with trading volume declining 24.39% to $280 million, ranking it 407th in market activity. The stock’s performance followed a strategic partnership announcement with Google Cloud to expand its cloud data management solutions, which analysts noted could enhance market penetration in hybrid cloud environments.

Investor sentiment was further bolstered by renewed interest in cloud infrastructure resilience amid rising data security concerns. The collaboration with Google Cloud is expected to accelerate Rubrik’s adoption in enterprise sectors prioritizing multi-cloud data governance. However, short-term volatility remains tied to execution risks in scaling the partnership’s infrastructure.

Back-test parameters for evaluating the stock’s performance require clarification on market universe boundaries, selection rules for volume-based screening, and pricing conventions. A synthetic index approach will be used to simulate a cross-sectional portfolio, but final execution depends on confirmation of data scope and methodology adjustments.
