Berkshire Hathaway's growing cash position is sending a clear message about what Warren Buffett thinks of stocks right now.

Warren Buffett isn’t the only one who likes the energy sector. Alongside Berkshire Hathaway’s huge purchases of Occidental Petroleum shares, insiders at energy companies have been buying large amounts of stock for weeks and selling very little.

Bank of America Corporation (NYSE:BAC) is arguably one of the best Warren Buffett stocks to buy, according to analysts, to gain exposure in the US banking sector. Best known for offering an array of banking services and investment products, it holds over $2 trillion in customer deposits, affirming its stability and credibility.
