01It watches for you

The watchlist thinks
like a fund manager.

Pro checks your stocks against fair value, quality and trend, day after day. If anything slips, you see it first. Two signals cover it:

  • ✓"On track"All good. The thesis holds, nothing to do.
  • !"Review"Fair value, quality or the 300-day trend has moved against you.
  • ✓Email alertsWhen a stock flips to “Review”, the email goes out the same day, with the reason. Free only gets a weekly look at three stocks.

knows fair value.

04The top-down process

From the whole market
to the one stock.

Work the way professionals do. Start with the whole market, narrow to a sector, filter hard. What's left is one stock and one verdict.

Whole-market analysis

Is the market expensive or cheap right now? Buffett Indicator, Fed Model, Shiller CAPE and our AI valuation give you one honest read.

Sector analysis

The heatmap shows which sectors and industries run hot and where value sits. One tap drops you into the industry.

Sector heatmap of market valuation

Country analysis

The world map colours every area by its gap to fair value. Continents including size classes and sectors are free; Pro adds the 40 countries individually, the zoom and the country spread of your own watchlist.

Screener with strategies

35,000+ stocks, sharp filters and ready-made strategies: Big Names, Top Rated, Buffett, Lynch, Greenblatt and more. Out the other end comes your shortlist.

Quick answers

Frequently asked

Do I need a credit card for the trial?

No. The trial starts without payment details.

Am I charged automatically after the trial?

No. Without a card on file nothing can be charged. After 14 days the trial ends and your account continues as a free account until you actively choose Pro.

What does Pro cost and when does billing start?

The first month is $1, then $9.90 a month. Billing starts only when you order Pro. Nothing is charged during the trial because no card is on file.

Trial or subscribe directly, what is the difference?

Both give you the same full Pro. The trial runs 14 days without payment details and ends on its own. If you are already sure, subscribe directly and pay $1 for the first month.

How do I cancel?

Any time in your account via subscription management, with no notice period.

What happens to my data if I go back to Free?

Your watchlist stays. Beyond 7 stocks it simply is no longer synced to the cloud, and the Pro tools are locked again.
