Investor Warren Buffett's Berkshire Hathaway will release its second-quarter earnings report Friday afternoon.
Berkshire's results are likely to be affected by the health of the housing market and how well BNSF railroad dealt with reduced demand for coal.
If developers continued building homes at a healthy pace in the spring, Berkshire's Shaw carpet, Acme Brick and Benjamin Moore paints will perform well. Berkshire also owns the HomeServices of America network of real estate brokers.
The paper value of Berkshire's derivative contracts can also cause big swings in its bottom-line net income.
The analysts surveyed by FactSet expect Berkshire to report earnings per Class A share of $2,163.63 on revenue of $43.25 billion.
