Given the macro environment I see a few possibilities.....
A sell off on decent volume and the PPS collapses....that would be a bearish mid/long term signal.
A sell off but on light or average volume...imo that would be neutral in the short to mid term.
Holding steady on light average volume....neutral - moderately bullish
Holding steady on above average volume....moderately bullish
Climbing on light volume - bullish
Climbing on higher than normal volume...very bullish
