C3.ai CEO Sells Shares Amid Mixed Signals
CEO Thomas Siebel’s recent sale follows a 40% stock drop but doesn’t necessarily signal trouble.
Thomas Siebel’s sale of 444,000 shares in C3.ai caught attention, especially after a 40% drop in the stock over the past year. However, it’s worth remembering this was part of a pre-agreed trading plan, not a snap decision based on fresh concerns. The bigger picture shows Siebel still holding a large stake, which suggests confidence. More importantly, the company bounced back after his return, with bookings surging 73% quarter-on-quarter. For South African investors, AI names aren’t directly accessible on the JSE, so the key proxy for risk appetite and tech sentiment here remains the USD/ZAR rate. If US tech stumbles further, the rand could weaken, pressuring local markets. On the other hand, a steady USD/ZAR might open windows for selective SA tech exposure, like Naspers and Prosus. Watch this space but stay cautious given sector volatility and lingering global macro risks. this is just our opinion and not financial advice
Hold off on chasing AI in global tech for now and monitor USD/ZAR closely; prefer trimming speculative tech-linked exposure in Naspers and Prosus until the USD/ZAR stabilizes.
