Observable signals
Signals that would confirm or change the reading
These are conditions to monitor, not price targets or forecasts.
A sustained move above zero would mark a meaningful repair in the stock/benchmark ratio.
Upside beta is higher than downside beta. The favourable split remains intact while that gap stays positive.
Rising beta means broad-market moves are carrying more weight; falling beta means ticker-specific forces are carrying more weight.
