Sika: Stock Research & Thesis
Portfolio & Investment Journal
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
Why did you buy this stock, and what would make you reconsider?
Sika keeps your investment thesis, valuation range and new evidence connected to each holding. Record your reasoning, follow the business drivers that matter, and review what changed after earnings, company news or a catalyst.
Keep your thesis on record
Write why you own a stock, what needs to stay true, your time horizon and your bear, base and bull values. Revisit earlier versions of your thinking.
Review the evidence
Use Thesis Map to connect business drivers, risks, catalysts and source evidence. Set watchpoints and review new information that may support or challenge your assumptions.
Connect research to your portfolio
Track holdings and watchlists with market quotes and valuation context. Keep research beside the stocks you own and the ideas you are studying.
Record your decisions
Capture a note or voice thought, then review suggested changes before adding them to your thesis. Record why you held, added, trimmed or exited so you can return to your reasoning later.
AI-assisted research helps organize the information. You make the investment decisions.

Your own reasoning, kept on the record.
MY THESIS
Write what has to keep being true for a stock you own - with your bear, base and bull values, your time horizon, the role the position plays, and how confident you are. Every save keeps the previous version, so your thinking is never quietly rewritten.
THESIS TIMELINE
Beliefs and actions in one ledger. Record a decision - opened, added, trimmed, exited, or reviewed with no action - and note what changed since last time. Filter to beliefs or actions to see how your view moved.
CAPTURE INBOX
Catch a thought the moment you have it, by note or by voice. Sika turns it into suggested edits to your thesis, and nothing lands until you approve it. Voice notes come back as text you can edit, and the recording is discarded after transcription.
TODAY'S REVIEWS
A short queue of what actually needs you, built from the watchpoints you confirmed. When there is nothing to review, it says so.
WATCHPOINTS AND ALERTS
Mark what you are watching on a position, then turn on Watchpoint Alerts to get a push when high-priority evidence lands on one - including evidence that runs against your thesis. Opt-in, and off until you ask for it.
KEY DRIVERS
Every driver now opens to its own page: what analysts expect against what was actually reported, the trend, why it matters, the full change history, and links to the sources behind each claim.
ALSO IN THIS UPDATE
- A rebuilt first run: pick a few stocks, set your first watchpoint, and see what an alert looks like before you enable anything.
- Analyst momentum now shows on position and watchlist screens.
- Deleting your account also revokes linked brokerage access.
- Plainer, more neutral analysis language, and tighter agreement between the numbers on a position and in its analysis.
