D.R. Horton's shares rose 3.4% before the bell as the company beat first-quarter profit estimates despite an acute shortage of properties on the market, largely due to labor and raw material shortages. U.S. homebuilding jumped to a nine-month high in December and new home sales increased 11.9% to a seasonally adjusted annual rate of 811,000 units in the month, the highest level since March, the U.S. commerce department said last week. "Housing market conditions remain very robust," Chairman Donald R. Horton said, adding that D.R. Horton was on track to deliver double-digit volume growth in fiscal 2022.
