A small local web app that answers "what moved, and why might it have?" at a glance. My Movers lists every holding by today's move, with the dollar change, the total gain on each position, its value and its volume against the average, plus a totals row weighted by dollars rather than a plain average of percentages.
Watchlist Movers does the same for names being watched, and Sector Rotation ranks sector funds by how they're doing against the S&P 500 over one and five days, so a rotation shows up early.
Every panel opens with a one-line summary in plain English ("Space leading sectors, also leads on 5-day, rotation building").
The Refresh button pulls free market data and re-prices everything. Which stocks are actually held comes from asking Claude to "sync my positions": Claude reads the brokerage through its own connector, so no brokerage login is ever stored on the machine.
A double-click launcher starts it, or just opens the browser if it's already running (2026-08-11).
