NPO beta and relative strength
Enpro Industries
NPO is weakening, but still above benchmark with market-like sensitivity to SPY.
NPO in rising and falling SPY weeks
These percentages count what actually happened in completed weeks. They describe historical participation, not certainty about the next move.
Rising and falling benchmark weeks have both produced consistent directional participation.
69% of directional weeks moved the same way.NPO also rose in 71% of 31 rising benchmark weeks.
NPO also fell in 67% of 21 falling benchmark weeks.
After 17 earlier matches by direction and movement level, more dependable when the benchmark rises.
NPO sensitivity to SPY
The benchmark relationship is weak and explains 12% of weekly movement over the latest year. Current beta is 1.06 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.
-13.3 point change in movement explained across two distinct 26-week windows.
The benchmark fit is too weak for the headline beta to be treated as a dependable description on its own.
Rolling beta
26-week estimates show whether market sensitivity is rising or falling.
Rolling relationship strength
Correlation shows direction; explained movement shows how useful the relationship has been.
NPO relative strength against SPY
The score compares the stock/benchmark ratio with its trailing 52-week average. Above zero means the ratio is above trend; direction shows whether that advantage is building or fading.
Relative-strength trend
Current score 7.18 ยท 13-week change -10.52
Stock, benchmark and worthwhile peers
Each path starts at 100. Sector and industry appear only when their Market Structure indexes have enough constituents.

51% of weekly movement explained by the industry over one year.
13-week and 52-week returns relative to SPY
This is a return bridge, not a claim of cause. It starts with the benchmark return, then shows the difference added at sector, industry and ticker level.
The largest source of relative weakness was the sector difference. NPO returned 1.5%; SPY returned 3.0%.
The largest source of relative strength was the ticker difference. NPO returned 38.1%; SPY returned 20.0%.
NPO in rising and falling benchmark weeks
Upside and downside beta are close, with no strong asymmetry in the current one-year window.
Strongest and weakest 13-week relative periods
Distinct 13-week windows prevent one long move from filling the list with overlapping dates.
Strongest relative periods
NPO 53.4% ยท SPY 15.3%
The return pattern shows that the industry added to the move, and the ticker moved beyond its peer backdrop.NPO 45.2% ยท SPY 10.3%
The return pattern shows that the sector moved the same way, and the ticker moved beyond its peer backdrop.NPO 22.9% ยท SPY -8.6%
The return pattern shows that the sector moved the same way, and the ticker moved beyond its peer backdrop.Weakest relative periods
NPO -15.3% ยท SPY 7.3%

The return pattern shows that the sector moved the same way, and the ticker moved beyond its peer backdrop.NPO -15.2% ยท SPY 5.3%
The return pattern shows that the sector moved the same way, and the ticker moved beyond its peer backdrop.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.
Drawdown from each rolling high
Worst available drawdown: NPO -31.4% ยท SPY -23.9%
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.
Upside and downside beta are close. A widening gap will show which side is taking control.
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.
