构建集中于半导体和AI敞口的科技股投资组合，并通过期权进行混合对冲
作者管理集中于半导体和大型科技股的多头组合及长期看涨期权，指出半导体驱动收益而大型科技股表现落后。
- 坚信AI基础设施需求将继续支撑半导体板块。
- 半导体敞口（尤其是MU和TSM）是投资组合收益的主要驱动力。
- 长期看涨期权为多年期科技增长趋势提供了有意的凸性敞口。
- 大型科技股目前正拖累投资组合的整体表现。
- 如果市场情绪转变，大型科技股的估值压缩可能会迅速抵消半导体带来的收益。
我一直在构建并积极管理一个集中投资组合，重点布局半导体、人工智能基础设施和大型科技股。
当前配置在长期股权敞口和少数长期看涨期权结构之间分配。
核心持仓包括MU、TSM、INTC、AAPL、MSFT、AMZN、GOOG和LRCX，此外通过期权增加了SNDK、CRDO和LRCX的敞口。
该投资组合并非完全方向性。部分头寸表现强劲，尤其是半导体板块，而大型科技股则表现参差不齐，目前对整体业绩构成拖累。
期权头寸主要为2026年到期的长期看涨期权，我更倾向于将其视为非线性的凸性敞口，而非短期交易。我清楚其中的风险特征，仓位控制是刻意为之，而非意外过度暴露。
关于当前结构的几点说明：
半导体敞口是收益的主要驱动力，尤其是MU和TSM的表现突出。
大型科技股敞口更为均衡，包含了表现优异者和滞后者，这是有意为之，作为对单一因子动量风险的广泛对冲。
我依然坚定看好人工智能基础设施需求将持续支撑半导体行业，但也意识到，若市场情绪转向，大型科技股估值压缩可能迅速抵消已有收益。
这并非短期交易型组合，持有周期从数月到数年不等，视具体头寸而定。
好奇大家在这个环境下如何平衡半导体与大型科技股的敞口。
You mention semis but no love for AMD?
Yes. I mentioned semiconductors. Of course. It’s not that I’m bearish on AMD. I just don’t like putting all my eggs in one basket. If you buy AMD, of course, I hope you’ll make a nice profit on it.
Missing the most important semi 😂 amd is going to continue to blow some minds
Sure. No problem. I hope everyone can make it to the moon this year!
I am still holding my Nokia at 4.59. Its a dozen shares, but I put them aside as fivers with change
I have similar positions, but I stopped adding to them about a year ago. Now only add to QQQ
I’m a fan
I greatly reduced my overall tech exposure since Oct last year. I dunno, mixed results. I've missed some run ups, but have had some decent gains in other sectors.
Makes sense.
I’ve been through similar cycles before. Reducing tech exposure usually “feels right” after big runs, but the market tends to stretch longer than expected.
That said, diversification has definitely been saving a lot of portfolios this year.
oh i agree it has been running longer than expected and people have been calling for a bubble pop for 2 years now.
i just wanted to cycle into different sectors to diversify. i've been nibbling back into tech where it makes sense for me.
also my personal goals have changed, so my time horrizon for my investments isn't as long term as it was say last year. before then I'd be fine sitting on good tech through stormy waters, but i need more liquidity for next year.
Yeah I think a lot of people underestimate how much portfolio behavior changes once time horizon shifts it basically forces a different type of positioning rather than just rotating sectors.
On my side I’ve been thinking about this more in terms of liquidity vs convexity rather than just sector exposure.
When liquidity becomes a priority, you kind of end up favoring names that can re-rate quickly or give optionality, instead of just holding through cycles even if the long-term thesis is intact.
The tricky part I’ve noticed is that the market doesn’t really reward reduced risk immediately you often end up missing parts of extended momentum before the rotation actually pays off.
