July 11 (Reuters) - Australian shares ended marginally higher on Tuesday ahead of Federal Reserve Chair Janet Yellen’s congressional testimony later this week which investors will glean for clues on when the central bank will again tighten U.S. monetary policy.
The S&P/ASX 200 index finished 4.46 points, or 0.1 percent, higher at 5,728.9 in a thin trading environment before Yellen’s semi-annual monetary policy testimony before Congress on Wednesday and Thursday.
“Most people have positioned their portfolios ahead of this (Yellen’s testimony) and very few people are prepared to react if she does really go into little more depth about her own personal views on financial conditions,” said Chris Weston, an institutional dealer with IG Markets.
“Her views at the moment are well known to the market and it shouldn’t be too surprised by what she’s saying now.”
