The Excel data covers 30 STI constituents plus the SPDR Straits Times Index ETF (ES3). It starts right on the day the STI first crossed 5,000 (12 Feb 2026), a move that local coverage linked to strong bank leadership and market-revival measures. From that high-profile milestone, the Excel data then shows a more mixed second half of February, where the index-level feel turned sideways, but a small group of cyclicals attracted more attention and delivered outsized price moves.
Across 12–27 Feb 2026, the Excel data shows Yangzijiang Shipbuilding (BS6) rising about 27.3% (S$3.41 to S$4.34) and Seatrium (5E2) rising about 12.1% (S$2.14 to S$2.40). Singapore Airlines (C6L) gained about 4.1%, while Keppel (BN4) gained about 3.3%. Over the same window, the three banks softened: DBS (D05) fell about 1.1%, OCBC (O39) fell about 1.6%, and UOB (U11) fell about 6.4%. The pattern fits the broader news flow: after the STI’s 5,000 breakthrough, post-Budget trading turned choppier and bank counters saw bouts of profit-taking.
The “rotation” shows up clearly when looking at where trading activity concentrates. Using the Excel data’s price and volume as a simple proxy for daily traded value, the banks’ combined share of attention fell from roughly 40.5% of traded value on 12 Feb to about 29.2% on 27 Feb. Over the same period, a basket of cyclicals (Yangzijiang, Seatrium, SIA, Keppel) rose from roughly 11.2% to about 26.0%. This does not prove a lasting trend by itself, but it does show that the market started “looking elsewhere” beyond the banks as February progressed.
A second signal is “follow-through” buying. Over 23–27 Feb (the part of the Excel data where ES3 prices appear), Yangzijiang rose about 12.4% and Seatrium rose about 8.6%, with both counters trading at roughly 2.7–2.9× their 3-month average volume on average in that same window. That kind of volume-supported rise often means investors reacted to fresh catalysts rather than just drifting with the index. In Yangzijiang’s case, local coverage tied the sharp move directly to stronger earnings. In Seatrium’s case, local reporting highlighted a profit surge, while industry coverage pointed to a more active positioning in the FPSO market, which can keep sentiment firm if contract momentum continues.
On the laggard side, the Excel data shows Venture (V03) down about 6.4% across 12–27 Feb, and local market reports singled it out as the worst STI performer on 27 Feb; that move lines up with the timing of its earnings news. Genting Singapore (G13) fell about 7.1% across the same window, and local coverage pointed to weaker 2025 net profit amid asset enhancement works. Sembcorp Industries (U96) fell about 3.0%, which also matches the tone of its results coverage describing a slight profit dip and weaker gas earnings.
Zooming out, the Excel data suggests the broader market was still “priced near good news” even after the pullbacks: on 27 Feb, about 55% of the names in the sheet sat within 5% of their 52-week highs. That matters for the next few weeks because it raises the chance of short, sharp profit-taking if headlines disappoint, even while the underlying uptrend remains intact. At the ETF level, ES3 (where available from 23–27 Feb) eased about 0.8%, so stock selection mattered more than simply being “in the index” during that stretch.
For what may rise in the coming weeks, the Excel data points to a short watchlist rather than a sure prediction. Yangzijiang and Seatrium show the cleanest combination of rising prices, heavy volume, and news catalysts; if the post-results momentum persists, they can remain leadership names, but they can also swing harder on any negative surprise. Singapore Airlines also looks constructive in the Excel data, and results coverage emphasised record revenue and still-healthy travel demand even though headline profit fell for accounting-related reasons; that mix can support sentiment if yields and loads hold up. Meanwhile, the banks may need time to stabilise after the post-5,000 digestion phase; they still anchor the STI’s long-term direction, but the Excel data shows they did not lead the February leg after the milestone.
From a simple core-and-satellite portfolio framing, the Excel data supports using ES3 as the core anchor (broad exposure, less single-stock risk), then treating the large, liquid “steady names” as core complements (for example, DBS/OCBC/UOB and Singtel, which the Excel data shows carrying roughly mid-single-digit dividend yields at the end of the period). Satellites suit the “momentum with higher swings” bucket: Yangzijiang, Seatrium, Singapore Airlines, and Keppel fit that description in this specific February window because they combined price strength with a noticeable pickup in trading interest. This remains a probability call, not a guarantee, and it works best when an investor sizes satellites smaller and monitors them more actively.
