1000 GMT - Singapore stocks look expensive after gains in recent years, HSBC analysts say in a note. Valuations have risen sharply following government-linked reforms to support the equity market, they add. While banks largely drove the market's gains on expectations of higher interest rates, the real-estate sector significantly underperformed. The analysts expect tighter monetary conditions to put further pressure on real-estate stocks. HSBC downgrades Singapore's equities to neutral from overweight and cuts its full-year target for the FTSE Straits Times Index to 5900 from 6100. The benchmark index closed 3.5% lower at 5412.96.
