Mumbai: The Bombay Stock Exchange (BSE) Sensex nose dived by over 192 points in opening trade on Thursday as foreign funds and retail investors booked profits made during the previous two sessions, taking cues from weak global markets.

Profit-booking by speculators after two sessions of gains also dragged the Sensex down.

Sensex, which gained over 376 points in the previous two sessions, suddenly fell by 192.27 points, or 1.03 percent, to 18,416.54 in the first few minutes of trade on Thursday.

Stocks of banking, realty, metals and auto companies suffered the most in the fresh sell-off.

Similarly, the wide-based National Stock Exchange Nifty index slid by 60.10 points, or 1.07 percent, to 5,531.90.

Market experts said the trading sentiment was bearish amid a subdued trend on global markets following weak US economic data.

In addition, the cautious approach adopted by investors ahead of the release of food inflation data on Thursday also dampened the sentiment, they said.

In the Asian region, Hong Kong's Hang Seng index was trading 1.69 percent lower and Japan's Nikkei shed 1.64 percent on Thursday. In the US, the Dow Jones Industrial Average ended 2.22 percent lower in Wednesday's trade.
