The Trading Journal Built for Long-Term Investors
Most trading journal apps are built for day traders logging entries and exits. Vexton is the trading journal for investors who hold for months or years — with AI-powered thesis creation and automated review cycles that keep your reasoning sharp.
You Never Know When to Sell
Every exit feels emotional — too early, too late, or driven by fear. You defined no exit rules before buying. You have no structured way to revisit your original reasoning. Your trading decisions are reactions, not reflections.
AI-Powered Thesis Journal with Automated Review Cycles
- AI agent creates structured thesis cards from your investment rationale — bull case, bear case, and exit criteria in one place
- Automated review cycles prompt you to revisit each position on your schedule — weekly, monthly, or quarterly
- Define exit criteria before you buy: price targets, stop losses, thesis invalidation triggers that keep you honest
- Full decision version history — every conviction change, thesis edit, and rationale update is logged with timestamps
How It Works
Create a Thesis Entry
The AI agent helps you articulate your investment rationale with structured bull case, base case, and bear case — plus key assumptions and pre-defined exit criteria.
Validate with Adversarial Audits
Periodic bull-base-bear re-evaluation tracks the health of your thesis over time. The adversarial audit generates an updated bear case — if it has deteriorated enough, it signals when it's time to exit.
Track Your Decisions
Every re-evaluation, conviction change, and exit decision is logged. Build a complete audit trail of your investing journey that you can learn from over time.
Frequently Asked Questions
What is a trading journal and why do you need one?
A trading journal is a structured record of every investment decision — why you entered, what you expected, and what actually happened. It turns scattered notes into a decision audit trail. Vexton automates this with AI-powered thesis cards that capture your rationale at the moment of purchase and track it over time.
What should a trading journal include?
A complete trading journal should include your thesis (bull case, bear case, base case), entry criteria, exit criteria, key metrics to track, and a log of every conviction change over time. Vexton's structured thesis cards include all of these fields by default, so you never miss a critical element.
How often should you review your trading journal?
For long-term investors, a quarterly review cycle works best — revisiting each position's thesis after earnings, macro shifts, or significant news. Vexton automates this with scheduled review prompts (weekly, monthly, or quarterly) and adversarial audits that re-evaluate your bull and bear cases so you're never caught off guard.
