And first up, we've got DuPont. It's falling today after China's top market regulator announced an investigation into DuPont China, that's a subsidiary for suspected violations of China's anti-monopoly law. This comes as China launches a series of countermeasures against the US following President Trump's tariffs that he would just announce. Other China-linked stocks are also taking a hit today. They include GE Healthcare and MP materials. Now, GE Healthcare shares actually seen a record drop. China is initiating an anti-dumping investigation into the imports of a type of medical X-ray tube from the US. That is a type of tube that GE Healthcare makes. And then you have MP materials taking a hit. China retaliating against US tariffs, uh, US export controls on rare earth MP is a maker or or a miner, I should say, of rare earth minerals. And then we've got one bright spot here today. It's the best performer in the S&P 500. It's a company called Market Access Holdings here. It's the operator of a leading electronic trading platform for fixed income securities. And it announced record total portfolio trading for March and the first quarter. Those shares are up 3% as we've been talking about, as money has come out of stocks, a lot has gone into fixed income as people are looking for areas they see as safer. That's been sending yields lower, sending prices higher, and obviously also just in general increasing some of the trading volume that we have seen in the fixed income market, which has apparently been a boon for a company like Market Access.
