WASHINGTON ( TheStreet) -- Pending home sales, a barometer for future home sales, rose in June for the fifth straight month, according to the National Association of Realtors. Its pending home sales index jumped 3.6% to 94.6 from 91.3 in May. Economists expected the index to come in at 91.2. Earlier today, D.R. Horton ( DHI) said it narrowed its loss in the third quarter, and on Monday Centex ( CTX) swung to a first-quarter profit. But shares of homebuilders were in the red on Tuesday morning, as investors are apparently remaining cautious on interpreting the trends. Centex tumbled 6% to $10.72, KB Home ( KBH) fell 1% to $16.97, Pulte Homes ( PHM) sank 7% to $10.94 and Lennar ( LEN) dropped 2% to $12. -- Reported by Jeanine Poggi in New York.
