* S&P 500 hits record high
* Microsoft touches all-time high on Pentagon cloud contract win
* Tiffany surges on LVMH's $14.5 bln bid

Oct 28 (Reuters) - The benchmark S&P 500 index hit a record high on Monday as a possible trade deal between the U.S. and China, and rising bets on a third rate cut by the Federal Reserve, bolstered investor optimism.
Meanwhile, shares of Microsoft Corp powered the three main stock indexes. The tech giant's shares touched an all-time high and were last up 2.6% after it won the Pentagon's $10 billion cloud computing contract, beating Amazon.com Inc . Amazon shares dropped nearly 1%.
The other two major indexes are less than 1% below their record levels. President Donald Trump said on Monday he expected to sign a significant part of the trade deal with China ahead of schedule but did not elaborate on the timing.
This added to Friday's optimism when Washington said it was "close to finalizing" some parts of a trade agreement with China. Beijing confirmed on Saturday that "technical consultations" on some parts of the agreement were basically completed.
"Markets seem convinced the first deal will get done and that negotiations are progressing on the next deal," said Edward Moya, senior market analyst at Oanda.
The news comes as a relief to investors who have been grappling with the fallout from the trade war, which was reflected in some of the dismal economic data this month.
