The stock market turned somewhat weak with the Bombay Stock Exchange benchmark Sensex falling by over 45 points in early trade on Tuesday on emergence of profit-taking at improved levels by speculators and funds amid a mixed trend in global equity markets.

The 30-share barometer which had gained 317.38 points on Monday, fell by 45.73 points at 10,229.87 after stocks of realty, banking, auto, oil and gas and capital goods retreated to profit-taking.
