Heavy rain and flooding in Chennai had an adverse effect on the stock exchanges, as shares of companies with operations in the city saw a decline.

Automobile and IT companies including TVS Motor and Infosys have suffered a major disruption to their operations in Chennai due to incessant rain.

Amid rising concern over its operations being hit by heavy rain in Chennai, shares of two-wheeler manufacturer TVS Motor plunged nearly 5% on Wednesday on the Bombay Stock Exchange (BSE), while the benchmark indices traded marginally lower.

"Incessant rain for the past three weeks in Chennai have had an adverse effect on the company's production during the period. The company's suffered sales loss of approximately 15,000 units due to inclement weather," said TVS Motor in a statement to the BSE.

Similarly, stocks prices of commercial-vehicle-maker Ashok Leyland have fallen more than 4% in the past three trading sessions due to excessive rain in Chennai. Its plant at Ennore on the outskirts of Chennai contributes to 40% of its overall production, NDTV Profit reported.

Shares of IT firms, which have many offices in Chennai, have also witnessed a decline. The sectoral BSE IT index fell about 1% compared to the just 0.2% decline the benchmark index.

While the shares of India's second-largest IT firm Infosys traded 1.5% lower, TCS shares erased all losses to trade flat.

"As a precautionary measure for the safety of our employees due to flooding at the Infosys campuses in Chennai, we have closed our offices today. To ensure client commitments are met, we are managing work from other locations," said Infosys.

Cement and oil-refining companies have also been adversely impacted by the heavy downpour in Chennai. Cement-manufacturer India Cements saw its share prices slump around 4%, while Chennai Petroleum Corp shares traded nearly 2% lower.

Chennai Petroleum Corp, a subsidiary of Indian Oil Corp, said it could suspend operations in one of its three refining units located in Tamil Nadu.
