$SANHUA(02050.HK) saw a slight gain, while $SERES(09927.HK) remained flat throughout the day. Parts suppliers rallied while OEMs stagnated—a pattern frequently seen in the NEV supply chain, typically signaling that the market prioritizes shipment volume over per-vehicle margins. Thermal management carries an additional option value from robot actuators, meaning its valuation anchor is no longer tied solely to automobiles. With the price war among OEMs still ongoing, how long can component makers sustain their profit margins? It appears they have room to breathe for now—the trading behavior of $SERES(09927.HK) suggests the market has lost hope in OEMs, instead offering some respite to upstream suppliers.
