The Straits Times Index (STI) achieved a new intraday high of 4,355.84 on 10 September before closing at 4,346.46, marking a significant milestone in its 2025 performance. This surge has extended the STI’s total return for the year to 19.6%, with an 11.5% increase since June. The rally has also propelled the market capitalisation of the Singapore stock market to S$983 billion.
Key contributors to the STI’s recent gains include Yangzijiang Shipbuilding, DFI Retail Group, and City Developments.
City Developments, in particular, has experienced the highest net institutional inflow relative to market capitalisation among the 30 STI constituents. These companies have also seen upward revisions to their consensus estimate target prices, reflecting strong investor confidence.
The new STI high coincided with DBS Group Holdings reaching a new high of S$52.87. With DBS comprising 26.4% of the STI, its performance significantly influenced the index’s consensus target, which rose to 4,491 this week. The recent upgrade by JP Morgan further bolstered investor sentiment.
As the STI continues to break records, the focus remains on the performance of its leading constituents and the broader market dynamics that are driving these gains. The ongoing momentum suggests potential for further growth, with investors closely monitoring developments in the coming months.
