MSFT
is likely to go down to around 172 before bouncing up from there .If it doesn't , If it continues dropping below the 172 area and closes considerably below the 172 in an upcoming day (With a bearish candle) then price is likely to continue its drop until around the 167.5 mark .For people who bought MSFT earlier (Long term investment) I think it would be wise to hold it as long as it doesn't considerably close below the 164,5$ mark.
