About Carter Yang
Carter Yang is 30, a senior backend engineer at a fintech company, and lives alone in a West Loop high-rise in Chicago that is mostly empty apart from two ultrawide monitors. He keeps three brokerage accounts that do not talk to each other, thirty-one individual positions tracked in a database he built himself, and index funds he treats as the serious money. He is down roughly $3,400 on options trades he declines to call gambling, and he maxes his retirement accounts every year without fail. The tension is what makes him useful: he builds financial software for a living, believes the boring strategy wins, and trades anyway.
He optimizes for optionality and for understanding the mechanism, and he is skeptical of authority that arrives in a suit. His register is dry and self-aware, occasionally smug after a win, and thick with jargon in both directions — engineering and markets. He asks about fee structure including order flow before he asks about price, and he treats a “no fees” claim as an invitation to find the revenue somewhere else. He will recommend a total-market index fund to a friend in the same breath as describing his own losing position, which is the clearest signal of how he separates what he does from what he advises. Urgency timers, guaranteed returns and course-selling end his attention immediately.
He is a strong subject for brokerage and trading-app research: onboarding friction, account funding, order entry, options tooling, and the reliability narrative a platform tells after an outage during a volatile session. He is the right persona for testing disclosure copy, because he reads it and can tell whether the plain-language version matches the footnote. He is good on consideration and on advocacy — he will tell ten people about a platform that earns him — and a reasonable proxy for the “would this survive finance social media” question. He is a poor fit for anything aimed at risk-averse or advisor-led investors.
His attention is concentrated online and moves fast: TikTok, YouTube, Google search, Reddit, X, podcasts, email and in-app notifications all score high. He scans business news before the open, keeps a market show on a second monitor at lunch, and reads a curated list of about thirty finance accounts. He treats one trading subreddit as entertainment and two others as research, and he comments rather than lurks. Instagram, Threads, LinkedIn and connected television sit in the middle; out-of-home, print, direct mail and Pinterest are close to irrelevant. Podcast sponsor reads reach him, but he checks the sponsor.
