The Sensex at the Bombay Stock Exchange fell 70 points, or 0.4 per cent, to 17,853 in early trade, this morning, on continued profit-booking by investors, and largely weak Asian stock markets. Later, selling pressure intensified considerably, and the Sensex had lost a hefty 384 points, or 2.1 percent, to 17,540 in afternoon deals, a short while ago. The 30-share Sensex has already fallen more than 500 points in the past three trading sessions. Other Asian markets in Japan, Singapore, South Korea and Indonesia were down by between 0.2 percent and 1.4 percent, on concerns that rising crude oil prices will hurt global economic recovery.
