As Warren Buffett famously said, "Price is what you pay; value is what you get." And there's no better time to find value than when the market is down.

The stock hit a back-to-back upper circuit on Thursday and Friday and it ended the week above Rs 34. The book value of the stock stands at Rs 27.1, while the current market price is Rs 34. The stock trades at a price-to-book value of 1.26.   

Amidst all this chaos, there was a group of stocks that hogged most of the limelight. These stocks belonged to shipbuilding companies and they rose between 4 and 13 per cent on a black Monday.
