STI unexpectedly dropped > -1.43%

The news on slower growth in Euro and markets in Euro down more than -1.25% to -2.28% could have triggered the late sell-off.

Sembcorp Marine got a sudden big sell-off, down -5.19%

STI 2796 (recent low) to 2832 (now) = 36 points, a mere +1.29%

If Euro or US markets are not dropping more than 1% tonight, STI should find some supports tomorrow at current level.
