description: "$JOYSON ELEC(00699.HK) and $SANHUA(02050.HK) have both dropped 4-5% in this wave, with both auto parts stocks weakening together. The new energy vehicle (NEV) supply chain has recently lacked news of new volume expansion or orders. Parts stocks are pulling back along with the cautious sentiment in the overall vehicle market. The thermal management systems of $SANHUA(02050.HK) and the automotive electronics of $JOYSON ELEC(00699.HK) are both segments that follow downstream demand. There's no specific negative news; it's more like sector-wide waiting. Upward momentum will only come after overall vehicle sales data shows signs of recovery."
