Billionaire investor Warren Buffett has been on a selling spree lately . As a result, his investment company, Berkshire Hathaway, is sitting on a record cash pile of $122.38 bn. To put it in perspective, India’s most valued firm TCS had a market cap of $121.23 bn on the day Berkshire reported its cash position. However, this is not the first time Berkshire's cash pile has exceeded the market cap of TCS.

But Buffett’s distaste of cash is well-known. So why is the 88-year-old investor sitting on such a large pile of cash?

Well, over the decades Buffett has built a reputation of being a value investor. He likes investing in companies with strong balance sheets that are trading below their intrinsic value. He also looks for long-term investments. So this increasing cash pile probably means that Buffett’s company is not finding good opportunities.

But speculations about companies that could make it to Buffet’s shopping list haven’t stopped. This includes NASDAQ-listed Cognizant, which has significant operations in India.
