去年开始我自己也觉得自己的投资策略不对，只是调整的比较晚了，AI直接上来就开骂我懒， Worth asking yourself: if you had $XM+ in cash today instead of it being locked in bricks and mortar, would you go buy X more Sydney houses with it? If not, that's a signal you're overweight by inertia, not by choice. 感觉CLAUDE的判断是目前AI股票有泡沫，它建议叫我卖掉一个投资房，把13万X3 的钱投到养老金里去，我说不想卖，最多拿每年结余现金和OFFSET账户的活钱投资，它就说我是赌徒心态。。。 I'll give you the factual landscape, but I want to push back hard first — because this request cuts directly against everything, we've spent this whole conversation establishing. You are about to recreate the exact problem you're trying to solve. We started this conversation because you're XX%+ concentrated in one asset (property). The whole rationale for moving into global shares was diversification and resilience. "Invest in AI" is a sector bet — arguably one of the most crowded, highest-valuation, most narrative-driven trades in the market right now. Putting new money specifically into an AI theme isn't diversifying away from concentration risk, it's swapping one concentrated bet for another. You already own a lot of AI exposure without buying an "AI ETF." A broad global index fund (the diversified strategy we discussed) is already heavily weighted toward the handful of mega-cap tech companies driving the AI trade — Nvidia, Microsoft, Google, Meta, Amazon etc. now make up a large chunk of global and US indices simply because of their market cap. So a chunk of your "boring, diversified" strategy is already an implicit AI bet. Layering a dedicated AI-themed ETF on top concentrates you further into the same handful of names and the same narrative twice over. Thematic ETFs are, structurally, a bet on timing. Dedicated AI/robotics ETFs on the ASX exist — Global X's GXAI and AINF, BetaShares' RBTZ, ETFS's TECH, and similar — and they factually give exposure to AI-related companies globally. But sector and thematic funds tend to launch and attract flows after a theme has already run hard, tend to be more narrowly concentrated (fewer holdings, higher single-stock weights) than broad index funds, and historically underperform broad indices over the long run precisely because investors pile in near the top of the hype cycle. That's not a prediction about AI specifically — it's the well-documented general pattern with thematic investing. You're 0-5 years from retirement — this is the worst possible time to add concentrated, high-volatility sector risk. We talked about sequencing risk earlier in the context of leverage; the same logic applies here. A single-theme tech bet is materially more volatile than a broad global index. If it corrects 30-40% (thematic tech/AI funds have done this before, repeatedly) right as you're winding down work, that's real damage to a portfolio that's supposed to be diversifying you, not adding a new source of stress. So — genuine question before I say more: is the appeal here that you believe AI is where the growth is and you want overweight exposure, or is it more that "AI" feels like the exciting/obvious place to put money right now? Those lead to different conversations. If it's the former, a small satellite tilt (say 10-15% of this year's $XXk, not the whole amount) on top of your core global index holding is a defensible way to express that view without abandoning the diversification strategy. If it's closer to the latter, I'd gently suggest sticking with the broad global fund and letting your existing AI exposure ride through it. |
