Stop selling your winning stocks too early.
Stockport makes your thesis actionable by reading out claims from your raw notes and keeping score against them.
It falls 22%, panic sets in and you want to get out.
When it runs up 30–40%, loss aversion says book it.
Either way, you've forgotten why you bought it. The reason lived in your head, or in notes you never reopen.
Stockport keeps that reason, holds you to it and stores how observations changed your thinking.
Take one stock you've researched.
Stockport turns your research into an actionable thesis.
It audits your raw notes to surface your bets and what would break or fulfil them. These conditions put a clock on your thesis.


Coach, your AI copilot, shows what would make your thesis stronger.
A claim with no break condition, KPIs you didn't define, a decision you're withholding: it asks for them now, while nothing is moving.

Results land next to your claims.
Mark what the quarter did to each bet. Log your verdict, and why.

When you panic, open your thought chain.
Every thesis state can be traced back to the original thoughts and evidence that shaped it, immutable in the form of thought chains.

Hold what's working. Sell what's broken, on your reasons.


Track and research stocks seriously, without quitting your job.
Stay on top of your holdings and watchlist.
One home for every stock you've ever touched. Held, watchlist, exited and passed. Each keeps its entire story with notes, claims and latest verdict, so you never start from scratch.

Your claims keep score for you.
Stockport comes with immutable “thought chains” which capture every thesis state change and the evidence/note + thought behind that change. Write a note the way you already do, link it to a claim and your reason joins its thought chain.

Nothing you read gets buried in your notes.
Mark a line as guidance, an event or a question while you read. It organizes them into easy-to-glance actionable items with no need to scour long notes.

Get performance insights that reveal your habits and patterns.
Marrying your losers? Momentum chasing? Inverse allocation? Phases with best/worst XIRR? Auto-computed from your logged or imported trades.

Four years of my own tradebook showed my stocks did better than my money. Timing and sizing were costing me. I built Stockport to fix that, and I run my own portfolio on it.@vikcr1703 on X Vikas Chandrawat on LinkedIn
