SembCorp Marine (S51) the ODD amongst the Crowd

Notice and observe something strange on this stock. Most opportunists would have captalising on the sell down of the so called D day on the 19th($2.81) and make entry on 20th, the next day in hope of gain from rebound. Price also dropped a lot already before (as in chart above) and S51 was in very oversold state. But instead the next day price went up in the early morning brisky to $2.86 and ended with very heavy selling pressure. Assuming that Day Trader went in at $2.85 - in the the heat of accelerating time, had to exit @ $2.77 prior to its close @ $2.76; nursing a huge loss on a single day. Today ended in shadowed doji/hammer. Shall keep a watch and seem better to ride on its uptrend rather than vice visa!
