Share price 5d avg (15-21 June) %change (5d avg) = -1.05% Today closing price = SGD 7.52 %change = +1.35% RSI rating overbought not conclusive. No "big fall" or "drop 10-20%" in price. In fact share price rebounced today. Someone still report "share price big fall" and "RSI proven" without valid data - confirmation bias selectively pick data to show what he believes.
