One of the most successful investors of all time, Warren Buffett, has built his fortune and reputation by following three simple rules when it comes to picking stocks for his holding company, Berkshire Hathaway (BRK.A -0.76%) (BRK.B -0.69%):

  1. He looks for companies that have a strong brand name, a solid financial position, and a durable competitive advantage over their rivals. These companies can withstand market fluctuations and management mistakes better than others.
  2. He invests for the long term, not the short term. He does not chase trends or fads, but focuses on the intrinsic value and growth potential of the businesses he owns. 
  3. He takes advantage of market panics and crashes to buy more shares of his favorite companies at bargain prices. He believes that "The best chance to deploy capital is when things are going down."

If you're looking for a Warren Buffett stock to buy hand over fist in July, you might want to consider Berkshire Hathaway. Buffett's holding company sports a diversified portfolio of businesses and investments that offer both growth and value. Here are three reasons Berkshire Hathaway is a great buy in July and beyond.

First, Berkshire Hathaway has an exceptionally strong balance sheet and a top-shelf business model. As of March 31, the holding company had $130.6 billion in cash and short-term investments.

Moreover, Berkshire Hathaway has a proven history of generating steady free cash flows, which indicates a strong and healthy business.
