BENGALURU, Sept 22 (Reuters) - Gold prices edged lower on Thursday as investors booked profits after a 1.5 percent rise in the previous session, opting for riskier assets like equities after the U.S. Federal Reserve held interest rates steady at the end of a two-day policy meeting.
The U.S. central bank, however, strongly signalled it could still tighten monetary policy by year-end as the labour market improved further. gold XAU= was down 0.3 percent at $1,332.80 an ounce by 0402 GMT, while U.S. gold futures GCcv1 rose 0.4 percent to $1,336.70 an ounce.
"People are expecting that the Fed is going to raise rates for sure in December. So, they have started to take profits," said Richard Xu, a fund manager at HuaAn Gold 518880.SS , China's top gold exchange-traded fund (ETF).
"The first phase of a gold run, which is largely driven by the Fed's inaction to raise rates, is over. The market is now looking three months ahead and taking positions accordingly."
Still, spot gold may retest a key resistance at $1,338 per ounce, as suggested by its wave pattern and Fibonacci projection analysis, according to Reuters technical analyst Wang Tao. rate environment looks less accommodative even it remains on a more gradual slope, meaning that oversized rallies in gold may not have much room to run," INTL FCStone analyst Edward Meir said in a note.
Ongoing strength in the equities could also hurt gold's prospects, Meir added.

"Indications out of the Federal Reserve that a 2016 rate increase is still very much a live possibility may restrict gains to gold above $1,340," said Sam Laughlin, precious metals trader with MKS PAMP Group.
"Initial support for the metal sits toward $1,330 ... while resistance toward $1,340 is keeping a lid on any moves higher."
