Foolish take
Cyber resilience leader, Rubrik, debuted on the markets in the middle of 2024 and has already seen its stock rise over 160%.
It looks like Hamilton Lane Advisors enjoyed most of this ride up and cashed out on their winning selection. With Rubrik's price-to-sales ratio rising from 7 to 15 in just one year, there's no denying the promising cybersecurity stock is now home to a lofty valuation.
To put this 15 times sales figure in perspective, if we assume Rubrik will mature to 20% net income margins, it would still be trading at 75 times earnings at today's share price.
However, Rubrik just grew revenue by 51% in its latest quarter, while seeing its existing customers grow their spending with the company by more than 20%.
Already integrated with the preventative cybersecurity behemoths of Palo Alto Networks, CrowdStrike, Zscaler, Okta, and Google's Mandiant, Rubrik might quickly grow into its lofty valuation.
