Since SIR started it's upward trend from 25th of July it has retracted 5 times. The maximum retreat was 21%. From a latest closing high of $2.79 to $2.30 = 18%. A similar story can be found with MAT & BUX. Based on the above all three are at the lower end and assuming that all three will continue the upward trend then I expect to see a reversal from today.
