Market conditions

Drawdowns and lead/lag relationship

Observable signals
Signals that would confirm or change the reading
These are conditions to monitor, not price targets or forecasts.
A fall through zero would show that the stock/benchmark ratio has moved below its trailing one-year average.
Downside beta is higher than upside beta. A narrowing gap would be the first sign of better asymmetry.
Rising beta means broad-market moves are carrying more weight; falling beta means ticker-specific forces are carrying more weight.
Strength shared by the peer group is broader; strength confined to the ticker is more company-specific and usually less stable.
