Portfolio updates, new stocks, and 2025 year end review It has been quite a year in 2025, with so many developments in AI, from DeepSeek shock and Trump tariffs to the AI Diffusion Rule, China blocking H20, Sam Altman’s 1.4 deal, and TPUs. But fortunately, with high conviction, we have made it through all of them and achieved strong gains in our wealth. Portfolio Performance 2025 performance: - QQQ: 20.16%. - S&P 500: 16.39%. - My portfolio: 66.76%. I still outperformed the S&P 500 by about 4x and QQQ by 3.3x. My 2025 performance is similar to 2023, when my portfolio was about 3.3x of QQQ. Read more about my portfolio allocations, updates and 2025 reviews below.






In light of this report, the recent news of a downward revision in TPU shipment forecasts from 4 million to 3 million units for 2026 appears highly counterintuitive. The floor for 2026 shipments should be at least 3.4 million units, comprising 3 million via $AVGO and 0.4 million from the $GOOG-MediaTek collaboration. This baseline excludes non- $TSM CoWoS capacity or any potential additional CoWoS allocations from $TSM to $AVGO. Looking ahead, I anticipate that TPU v7e shipments alone could exceed 1 million units in 2027.
