One of the way to spot uptrending and downtrending stocks is to see the stocks that is at month high or month low, usually we monitor this few times a week to see if some names appear very frequently – meaning they are LIKELY to be downtrending (Everyday make new low) or uptrending (everyday make new High)
For instance, HKland, KLW and Federal. We see them quite often, ya right they up everyday 😉
Ezra drop like crazy this few day, they are in this monthly low list.
Bottomline: stocks at 20days high/low not necessary always means that it is trending. They could be sideway trend and is at/near support. E.g UOB
