Singapore’s COE hitting S$125k again tells you something important: demand for private mobility in Singapore remains structurally strong despite extreme pricing. But it also highlights why automakers like BYD are entering a much tougher phase — growth is no longer just about selling EVs; it is now about defending margins, brand positioning, and long-term market share.
Singapore is actually a good microcosm of the global EV industry right now.
BYD has executed exceptionally well in Singapore. It captured roughly 24% market share in Q1 2026 and became the dominant EV player locally, benefiting from EV incentives, aggressive pricing, and strong dealer execution. EVs now account for more than half of new car registrations in Singapore. 
But the stock market is starting to look past pure delivery growth.
BYD’s valuation is no longer “cheap China EV growth.” Depending on the listing referenced, the stock trades around ~25x–50x trailing earnings, which is still a premium multiple for an automaker.  Investors are now questioning whether BYD can sustain high growth while China’s EV market enters a brutal price war phase.
That concern is justified:
* BYD’s 2025 sales growth slowed to its weakest pace in five years. 
* Q1 2026 profit plunged more than 55% YoY amid intensified competition and weaker domestic demand. 
* Chinese EV competition is no longer just Tesla vs BYD — Geely, XPeng, Leapmotor, Xiaomi and others are compressing industry margins aggressively. 
The Singapore COE cycle adds another layer. Historically, extremely high COEs eventually suppress replacement demand because buyers delay purchases or downgrade. Singapore’s supply-driven COE system also means future quota increases could cool premiums later in the cycle. So while BYD benefits from the current EV adoption wave, the Singapore market itself is not an infinite growth engine.
That said, BYD still has real strengths:
* vertical integration,
* battery leadership,
* strong ASEAN expansion,
* manufacturing localisation in Thailand, Malaysia and Indonesia,
* and scale advantages few competitors can match. 
My view: BYD is probably no longer an obvious “Buy at any price” momentum story. But neither is it a clear sell.
I would rate it a Hold.
The long-term EV trend remains intact, and BYD is still one of the strongest global EV players. However, near-term earnings pressure, slowing growth, and rising competition make it difficult to justify aggressive upside from current valuation levels unless overseas expansion materially accelerates.
In short:
* EV adoption = bullish
* BYD execution = still strong
* Margins and valuation = the key risk now
The next phase for BYD investors is not about whether EVs will win. It is about whether BYD can keep winning profitably.
