What rubbish. Nvidia doesn't need to sell cheaper chips to gain market share, they just need their clients to be able to buy them. If the market is closed off there is no substiture. Any curtailment of sales into China is a net loss for Nvidia.
Nvidia’s Jensen Huang Fears Losing the Chinese Market. One Analyst Says That’s Short-Term Thinking
$MicroStrategy(MSTR)$ Will this become a BTC holding company if the legacy business continues to take a back seat, and eventually face delisting like normal cash-hildjng companies?
$Tesla Motors(TSLA)$ Tesla cutting prices to increase demand shows how competitive the environment is. But having said that their margins are higher than the other majors for EV especiallyin China, so the price war is potentially more damaging to the other players. European investigation on subsidies pose an overhang on share prices, but I think it will take a while to be concluded. AFAIK such subsidies were paid to manufacturer to reduce selling price per car, but mainly domestic sales. Other more indirect subsidies like paying to battery makers to help development of new technology is harder to quantify, similar to US CHIPS Act.
