What this does not say

Describes how many independent directions the risk occupies. It is not a forecast of loss and does not predict a drawdown.
This is commonality, not a fault. A diversified equity book is MORE driven by one shared direction than a single stock is, because diversifying is what removes the idiosyncratic part.
Past window only. Says nothing about the next one.
Noisier than it looks: on sixteen years of a 60/40 book the 90% interval around this figure is about a Sharpe of 0.5 to 1.4. Read it as a band, not a score.
The worst fall *in this window*. A longer window would very likely contain a worse one.
Loading signs are fixed so the largest is positive; a negative loading means that holding moves against the others.
The ratio is the finding. A weight alone cannot say whether a position is large, because that depends on everything else held.
Today's weights are held fixed across both stretches. This is what the MARKET did to the book you hold now — not a history of the book, which this app does not store. Reading it as 'my trades caused this' would be exactly backwards.
The window ends at the youngest holding: one recently listed position shortens the history for all of them.
