(Updates comment and adds late prices)

By Ellen Freilich

NEW YORK (Reuters) - U.S. Treasuries climbed
Thursday as fresh stock losses revived a bid for safe-haven
U.S. government bonds, even with yields at their lowest levels
in more than a year.

Anticipation of Federal Reserve Chairman Ben Bernanke's
remarks Friday at the annual symposium in Jackson Hole,
Wyoming may also have lifted prices.

Stocks finished broadly lower.

Bernanke's speech will be the Fed chief's first public
comments since the U.S. central bank said it would invest
proceeds from its holdings of mortgage bonds to buy more
long-term Treasury securities to support the economy, a move
some saw as a timid response to a faltering recovery.

After more weak economic data this week, Bernanke will
offer his outlook on the economy and possibly outline some
action to reverse the deterioration, analysts said.

"People are waiting for more clarity from the Fed and the
Administration in terms of another round of stimulus," said
Michael Collins, senior investment officer and co-portfolio
manager for Core Plus Fixed Income strategies at Prudential
Fixed Income in Newark, New Jersey.

Collins cited "a lot of chatter" about the government or
the Fed "trying to do something" to lower mortgage rates to
help consumers.

"The market will be intently focused on what Bernanke has
to say tomorrow about any new stimulus or quantitative easing
plans," he said.

With uncertainty still as high as U.S. government bond
yields were low, the Treasury's auction of $29 billion of
seven-year notes drew a solid bid.

"As yields have eroded in recent months, investors are
moving (farther) out the maturity curve," said Thomas Simons,
money market economist at Jefferies & Co in New York.

Since the seven-year notes offered about 60 basis points
more in yield than five-year notes, it seemed "a logical place"
for investors to go, he said.

Early in the day, bonds temporarily gave up some gains on
news that new claims for U.S. unemployment benefits fell last
week. But claims remained high and bond prices appeared
oblivious to the potential correction some claim is looming.

The market is debating whether bonds are overpriced, or if
the faltering U.S. recovery will underpin U.S. government debt
until economic indicators begin to improve consistently,
particularly on the hard-hit labor market. For now at least,
the latter argument appears to have the upper hand.

In late trade, the 30-year long bond was up
1-5/32 in price, its yield falling to 3.51 percent from
Wednesday's close of 3.57 percent. Analysts said resistance lay
at 3.51 percent and support at 3.82 percent.

The benchmark 10-year Treasury note rose 17/32
in price, its yield easing to 2.48 percent from Wednesday's
close of 2.54 percent. Analysts put resistance in 10-year notes
in the 2.44-2.46 percent area and support at 2.67 percent.
