Grandeur Peak Global Advisors significantly reduced its stake in Bruker Corporation by selling 709,697 shares, representing a $29.54 million net position change in Q3. This move comes as Bruker's stock has slid 18% over the past year, underperforming the S&P 500, and is attributed to fading confidence due to declining revenues and organic growth. Despite cost-cutting measures, analysts suggest investors are being asked to wait for a rebound while other opportunities may offer faster growth.

Fortinet (FTNT) is expanding its AI infrastructure security offerings through partnerships with Arista Networks, Monolithic Power Systems, and NVIDIA, integrating its firewall directly into AI compute stacks. Despite a recent share price stall (down 13.73% YTD), the company boasts a strong three-year total shareholder return of 67.74% and high profitability. According to analyst assessments, FTNT is currently undervalued, with a fair value of $99.03 against its last close of $81.74, driven by its robust profitability and disciplined growth model.

Arista Networks is expanding its market reach beyond core data centers into AI-centric security, campus, and industrial edge use cases through collaborations like the Secure AI Data Center solution with Fortinet and new AI-driven campus networking features. While these moves are strategically important for diversification, the company still faces the risk of concentrated exposure to a few hyperscale and AI customers. Arista's projected revenue and earnings growth suggest a significant upside to its current price, but analyst views on customer concentration vary widely.
