Ant's Portfolio Update December 2025

2025 YTD Monthly Closing
Jan +9.8%
Feb +1.6%
Mar -13.8%
Apr -6.7%
May +8.5%
Jun +19.0%
Jul +24.6%
Aug +30.8%
Sep + 42.1%
Oct +55%
Nov: +36.2%

Dec 31st: +31.9% YTD (down from a YTD intraday peak of +57% on the first trading day of November and up from April low of -25%).

December continued to reflect the recent weakness and volatility experienced in my portfolio since the November break from the almost straight line ascent from the pivot point in April following the dramatic pull back in the first half of the year. I estimate that I am back to about ~25% away from reaching my portfolio ATH (2021 & Nov 3rd 2025).

This is an improvement in terms of Portfolio gains vs 2024, (which finished +26.9%) as well as against both S&P and Nasdaq Index benchmarks, which the portfolio comfortably beat in 2025 but barely matched in 2024.

I also notice In both 2024 and 2025 there was a year end tech/growth/momentum sell off that dramatically lowered the finishing position in the final month (2024) or two (2025).

Thematically, I’m principally invested in:

eCommerce (20%) - Shopify, MercadoLibre, Global e-Online & SEA

AI & Cloud Infrastructure (25%) - Cloudflare, Pure Storage, Nvidia, Nebius, Astera Labs, Micron, Tempus Ai, IREN, HIVE, CoreWeave, Credo, EOSE & Electrovaya

Software (SaaS/DevOp/Data analytics) (25%) - Palantir, Datadog, Snowflake, GitLab, Monday, Axon & Samsara

Cybersecurity (10%) - Crowdstrike, ZScaler, Rubrik & SentinelOne

Fintech/Payments/Crypto (10%) - SOFI, Toast, Robinhood, Upstart, Bill, Pagaya & Bitmine Immersion Technologies

AdTech (10%) - The Trade Desk, Applovin and Reddit (ad community)

Recent Activity -

I sold out of MongoDB after its post ER bump and switched proceeds into adding to: ALAB, AXON and Pagaya and taking starting positions in Credo, CoreWeave and EOSE.

Considering trimming Palantir further, maybe Pure Storage and Shopify. Would like to enter Transmedics. Also considering Lumentum & Rocket Lab.

Holdings in GitLab & BILL sit closest to the exit door whilst I missed the window to sell or top slice TTD and IOT further.

I took strong encouragement from Calendar Q3 results from: Micron, Palantir, Cloudflare, Nvidia, Datadog and ZScaler whilst I felt was Axon was mixed and Monday concerning.

Bigger Picture -

As sectors, Cyber Security, AI and Cloud infra/DevOps and ex US eCommerce have been relatively strong - as well as profitable SaaS plays/software providers with rising consumption and ones with demonstrable AI use cases. Payments & Fintech had been strong with rate reductions back on the cards, expectation of spending resilience and a boom in crypto/alternative/private investing whilst AdTech is showing signs of weakness in pricing and demand.

Specifically with this latest clutch of results it feels as though every part of the data space is doing well and reaccelerating; (semiconductor, memory, storage, servers, data center infra, databases & data cloud). It remains to be seen whether AI is going to “eat” software but data and infrastructure still appears AI resilient.

I see the outcomes of 3 challenges: i) the will it won’t it question of “AI eating software”, ii) the alternative scenarios of higher for longer vs an AI bubble and iii) the formulation and reaction to Macro (tariffs & trade), fiscal (tax & spend) & monetary (Fed rates) policies are the critical determinants of market success right now - certainly for my portfolio holdings.

The potential for macro damage on a sector and company basis is clearly having an impact. With the prevailing politics and in particular economic and trade policies as well as sector/company targeted government interventions we are facing some hyper volatility with big winners and losers and not necessarily driven by innate company consideration.

I still think that seeking out growth companies with defensive qualities, (cloud infrastructure, cybersecurity, energy generation, storage and supply even and consumption based rather than seat based software models), might do better in these volatile and uncertain times as well as ex US eCommerce and trading plays that benefit from US currency weakness but more importantly are removed from US import/export movements on an intra regional / local to local basis (e.g. MercadoLibre, SEA and Grab).
