National Steel Company shares fall 1.96% premarket amid US tariff concerns and weak European medical technology sector.

National Steel Company fell 1.96% in premarket trading. The decline in stock price may be attributed to the overall negative sentiment in the market, as indicated by the European stocks being down on Thursday following losses in major U.S. indexes on Wednesday. Additionally, the threat of additional US tariffs on the European medical technology sector weighed heavily on investor sentiment, creating further uncertainty.
