Berkshire Hathaway's shares fell by around 1% this week, while the S&P 500 edged 0.6% higher. The company's A and B shares are now down 13% from their all-time closing highs almost a year ago. The S &P has gained 26% over the same period. However, this drop is making the shares more attractive to some investors. Analysts suggest that Berkshire is trading at an 8% discount to its intrinsic value and that its stated policy is to buy back shares when "the repurchase price is below our intrinsic value." However, there is still room for improvement on the operational and investments sides. Greg Abel, the CEO, will be asked about his plans to use Berkshire's nearly $400 billion in cash and equity investments at the Berkshire shareholders meeting.
