Benchmark fit
MGR sensitivity to SPY
The benchmark relationship is partial and explains 23% of weekly movement over the latest year. Current beta is 0.42 and is stable.
A wider range means the beta estimate is less precise.
How consistently rolling beta has held its level and direction.
The weekly regression intercept annualised; it is historical, not expected return.
Annualised volatility of returns above or below the benchmark.

Market conditions

Drawdowns and lead/lag relationship
The strongest link is in the same week. Lead/lag evidence is treated as secondary because timing relationships can change quickly.

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.
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.
