Top 5 Large cap gainers and losers this week.

Indian Railway Catering And Tourism Corporation:

Shares of Indian Railway Catering and Tourism Corporation (IRCTC) are trading close to the 52-week high of Rs 4,965. The stock gained 23.90% in this week on the back of heavy volumes, ahead of a 1:5 stock split. Among the other factors fueling the surge in stock price are the monopolistic nature of the business and the economic recovery coupled with an increase in travel given the vaccination level against the Covid-19 infection.

Deepak Nitrite:

Stocks from the chemical sectors also saw a huge buying momentum this week and Deepak Nitrite was no exception. The buying was driven by the perception that the sector is set to see another leg of earnings boom thanks to the troubles in China. The country's power crisis is forcing its industries to cut back on production, which in turn is pushing prices of several chemical intermediates higher in the international and domestic market. Deepak Nitrite has so far rallied 20.54% this week and is approaching its 52-week high of Rs 2,944.95.

Sona BLW Precision Forgings:

On the back of its collaboration with IRP Nexus Group this week, the shares of Sona BLW Precision Forgings have surged 16.22 per cent so far. The wholly-owned subsidiary of the company Sona Comstar entered into a collaboration agreement with IRP Nexus Group, Israel, to develop, manufacture, and supply a Magnet-less Drive Motor and the Matching Controller for Performance Two-wheelers and Three-wheelers for the Global Market. Under the arrangement, Sona Comstar will pay onetime license fees and royalty to IRP Nexus to have the exclusive rights to manufacture the System in India and non-exclusive rights to sell and distribute the System globally for 7 years. The company believes that this new technology will have wide-scale implications and the potential towards environmental sustainability, besides reducing the cost of EV vehicles.
