* Durable goods post largest gain in two years
* New home sales rise at fastest pace since Sept 2008 (Updates to midday)
U.S. stocks seesawed on Wednesday despite strong data on new home sales and durable goods orders as investors paused after a recent sharp run-up.
Sales of new homes rose in July to their fastest pace in 10 months, while orders for long-lasting manufactured goods surged, hinting a modest economic recovery was taking shape. For details see [ID:nN26259327].
For the third consecutive day, equities briefly bounced after favorable news, but the gains fizzled.
New home sales were better, but given the recent data we've had I don't think that was a surprise, said Michael James, senior trader at Wedbush Morgan in Los Angeles.
James said investor psychology is focusing on the fact that we've had up moves and then sold off both Monday and Tuesday. After today's initial surge, buyers are becoming a little tired.
