Lennar Corp., the second-largest U.S. homebuilder, jumped the most in nine months after reporting higher-than-expected earnings for its fiscal second quarter as the revived U.S. economy spurs new housing demand.

Net income for the three months through May was $183 million, or 79 cents a share, compared with $137.7 million, or 61 cents, a year earlier, the Miami-based company said in a statement Wednesday. The average estimate of 12 analysts was for earnings of 64 cents a share, data compiled by Bloomberg show.
