Is there any reliable way to analyze pre-market and afterhours data?
My understanding is that for the retail investor its unreliable since the majority of pre and afterhours traders are big institutions and there is so little liquidity at those times that it isn't really a good measure of market sentiment since it could just be institution backing up up longstanding positions or hedging against their actual ones.
Is this a proper assessment or is there anyway to screen for market sentiment say if you see a security down x % pre market and want to see if the trend continues after the bell?
