Everything in the feed moved today. One of them moved your book.
Prices and earnings are only half of it. Rates, the curve, the dollar, oil, sector rotation, volatility, a split, a theme running through forty headlines — the five lenses read all of it, and throw away whatever doesn't reach your holdings.
All four quality lenses still read positive, and the AI capex theme has run in its favour for three quarters. That is the finding: it is now 24% of your book, and Portfolio Fit puts the target below where the position already sits.
Public beta — FREE, opens on 15 October. No card.
Illustrative — every company on this page is inventedThe story didn't stop when you bought.
You did the research when you bought — that reasoning is your thesis. It then sat still. Earnings, margins, the rate regime, an AI capex cycle that ran three quarters in its favour, and the weight the position quietly grew to inside your book did not.
Somewhere the two stopped agreeing. The price chart is the last place that shows up.
One briefing. Ranked by what actually needs you.
Not a feed. A single page: the Tension Line headline, the holdings that have moved far enough from their target to be worth reading — each with the lens breakdown that produced the reading — and, if you have logged cash, where the analysis ranks it.
If you would rather not open the app to find out, a short email can say what changed.
Most mornings that takes ninety seconds.
Five lenses. One number you can take apart.
Four lenses read the business — risk, momentum, quality at this price, and the economic regime — and combine into conviction.
Portfolio Fit then transforms conviction into a target weight — it is not a fifth number added to the average, it is what turns a score into a position.
Which is why a company every lens likes can still read Weakening. That is not a verdict on the business. It is a statement about what the business already occupies in your book.
Move a lens. Watch the reading move with it.
The weighting is yours, not ours. Northwind rode the AI capex cycle to 24% of this book. Drag Portfolio Fit's weight and watch a position every lens still likes turn into Weakening purely because of what it already occupies.
Four lenses like the business. One asks what it already occupies.

It doesn't get louder. It gets better calibrated.
Every call is written down before its outcome is known, and scored when it resolves — so what the engine says can be checked against what happened.
Free while you test it. One plan when you don't want to.
