Technical analysis
Straits Times Index (STI)
Bearish 5,419.38 -3.37% liveThe Straits Times Index is below its SMA20 and SMA50 after falling to the bottom of its 20-day and 60-day ranges.
Daily candles, last 90 sessions. Green dashed = support, red dashed = resistance.
The Straits Times Index closed at 5432.18, down 3.14% for the day and 4.15% over five sessions. It is below the SMA20 at 5666.84 and SMA50 at 5690.12, showing that the short- and medium-term trend remains under pressure.
The 20-day and 60-day lows are both at 5429.22, making this the immediate downside reference. RSI, or relative strength index, is at 29.04, which signals weak momentum and an oversold reading, but does not by itself confirm a reversal. The pivot, a reference level calculated from recent trading, is at 5630.43.
A sustained move back above 5554.98 could reduce immediate downside pressure, while 5581.71 and the pivot at 5630.43 are higher recovery levels to monitor. Failure to hold near 5429.22 would keep the index close to its recent range low.
USD/SGD
Bullish 1.2807 +0.25% liveUSD/SGD is above its SMA20, SMA50 and EMA20, with price near the upper end of its 20-day range.
Daily candles, last 90 sessions. Green dashed = support, red dashed = resistance.
USD/SGD closed at 1.2801, up 0.20% on the day and 1.26% over 20 sessions. Price is above the SMA20 at 1.2764, the SMA50 at 1.2752 and the EMA20 at 1.2769, giving the pair a firmer technical structure than the equity instruments.
Momentum is positive but not stretched: RSI, or relative strength index, is 58.43. The pair is above the pivot at 1.2787 and has nearby reference points at pivot resistance 1.2798 and 1.2821. The 20-day high at 1.2824 is the upper range reference, while the 14-day average true range, or ATR, is 0.0037.
A move below 1.2787 would weaken the immediate structure and bring 1.2764 into focus. Holding above the moving averages would keep the recent upward bias intact, although the 1.2821-1.2824 area may act as a test of range strength.
DBS Group (D05.SI)
Bearish 73.53 -5.11% liveDBS Group is below its SMA20 and SMA50 after a sharp decline to its 20-day low, with price still above its 60-day low.
Daily candles, last 90 sessions. Green dashed = support, red dashed = resistance.
DBS Group closed at 74.25, down 4.18% on the day and 4.02% over five sessions. The close is below the SMA20 at 77.35 and SMA50 at 76.69, while the latest low at 74.00 matches the 20-day low and sits above the 60-day low at 71.37.
RSI, or relative strength index, is 34.34, reflecting weak momentum without reaching the oversold reading seen in the Straits Times Index. The pivot is at 77.77, with pivot support levels at 77.03 and 76.56 now above the current price. This makes those levels potential recovery checkpoints rather than immediate support.
Stabilisation above 74.00 would be needed to contain the latest decline. A recovery through 76.56 and 77.03 would improve the short-term structure, while a break below 74.00 would place the 71.37 60-day low in focus.

The most relevant scheduled events are US dollar releases, which may affect USD/SGD and broader risk sentiment. FOMC Member Waller speaks at 12:30 UAE time on Thursday, followed by US Unemployment Claims at 16:30 UAE time, with a forecast of 200K against a previous 197K.
On Friday at 18:00 UAE time, Preliminary University of Michigan Consumer Sentiment is scheduled with a forecast of 47.5 versus 47.8 previously. Preliminary Inflation Expectations is released at the same time, with a previous reading of 4.6%. Currency volatility can increase around these releases, while weaker or stronger readings may also influence sentiment toward Singapore equities.
Algo insight: how a rules-based system treats today
A rules-based algorithm would treat the Straits Times Index and DBS Group as high-risk downside conditions after their sharp daily declines and closes below the SMA20 and SMA50. Their ATR readings are 63 index points and 1.10 Singapore dollars respectively, so any risk control would need to account for those normal movement ranges rather than using a fixed distance.
USD/SGD has a 14-day ATR of 0.0037. An algorithm may therefore reduce position size when volatility expands, keep risk proportional to the instrument's ATR, and avoid increasing exposure after an extended move near the 1.2821-1.2824 resistance area.
Rules-based systems commonly avoid opening new positions immediately around the 12:30, 16:30 and 18:00 UAE releases, then reassess after spreads and price volatility settle. Session timing should also be separated from signal generation so that a move during a high-impact release is not treated as a normal trend confirmation.
