The BSE Sensex lost 3 percent in the week ending Aug. 2, extending its losses from the previous week and marking its biggest weekly fall since mid-March.
Markets remained on the edge on uncertainty over how long the Reserve Bank of India (RBI) would continue measures to defend the rupee. The rupee fell 3.4 percent over the last five trading sessions and ended at a record closing low on Friday.
The central bank left the repo rate and cash reserve ratio unchanged at its policy review on July 30, but said it will roll back recent liquidity tightening measures when stability returns to the currency market.
Here are the top five losers and gainers:
Coal India: Shares in the state-owned firm ended the week down nearly 10 percent, taking its losses for the year to 28.3 percent. On Friday, the stock fell around 6 percent and hit an all-time low of 250.65 rupees during trade. The stock has now been down for three consecutive weeks.
On July 30, the government said it will sell a 5 percent stake in Coal India. In 2010, India sold a 10 percent stake in the company, raising $3.4 billion in an IPO.
