Investing, out in the open
I've been investing since 2000. I started in the dot-com boom and have been through three crashes since. I studied economics with a specialization in finance: portfolio theory, Black & Scholes, currency swaps and interest rate swaps. Since then I've watched that theory meet real markets.
I am an accredited investor. Alongside a public stock portfolio, I hold a set of pre-IPO stakes, and I had an exit in the Airbnb IPO. Technology and communication services are my biggest bets, and I keep a cash reserve as dry powder: after enough market cycles, you learn to stay liquid.
On X I post as @CAAccomplished: quick takes on market moves, and deep dives on the stocks I own and follow. The deep dives are published here in full, as research reports. Alongside them I share my point of view on wealth, generational wealth and tax. No hype and no tips: the work, and the lessons from twenty-five years of it.
Stock research
Full reports, newest first. Every report is dated, states its watchlist stance on the first page, and is built from company filings and other public sources.

Apple is growing 16%, and about two points of margin are one-off.
June-quarter sales rose 16% with gross margin at 50.1%, though tariff refunds added about two points and memory costs are rising. Watchlist: demand is strong; memory cost, the end of tariff refunds and a 37x forward multiple decide what the next prints are worth.

Airbnb is growing 17% with wider margins, helped by FX and tax.

GMV grew 15% in Q2 2026 on a 24% jump in US volume, and the shares trade above the average Street target. Watchlist: operating momentum is strong; durability beyond Q3 and the status of GameStop's rejected $125 bid are what to watch.
