A more sustainable support rests at 652, which represents the 38.2 per cent Fibonacci retracement from the significant low of 470 to the recent 765 high.
Fibonacci retracement is based on the idea that markets will retrace a predictable portion of a move, after which they will continue to move in the original direction.
This in turn greased a slide on KLCI to the low of 657.15, which lied just above the crucial 38.2 per cent Fibonacci retracement support at 650.
