Daphne Tan, director of business development at CMC Markets Singapore, says: “The STI breaking 4,000 is a key psychological milestone, which could be interpreted as strong investor confidence, resilient blue-chip performance, and a favourable economic climate. Strong contributors in the STI include the banking and telecommunications sector. Breaking this level suggests a strengthening sentiment, but sustaining it would depend on global stability and market fundamentals.”
