The recent surge of SNDK over the past few days must be very exciting. It’s the kind of rebound after a drop that was too severe—an impressive rally from 1000 to 1800. However, for the main upward wave at the mid-term level to start again, it still needs signal confirmation. The main-upward-wave buy point has not been triggered yet. In previous instances, it would keep oscillating repeatedly. This time, the short-term pullback target from 1800 can refer to 1400U. Or, a trend-reversal candlestick could appear earlier. Be patient— the key level is around 1400.
