Historically, Trump's protectionist policies have had mixed effects on the tech industry. The tariffs on steel could lead to increased production costs for companies that rely on steel in their manufacturing processes, potentially affecting their profitability. However, Nvidia's primary business is in semiconductor manufacturing, which may not be directly impacted by steel tariffs. The indirect effects, such as changes in market confidence and potential supply chain disruptions, are also uncertain. Given the information available, the post does not provide a clear indication of how Nvidia will be affected, leading to a neutral sentiment score. The link shared in the post discusses steel tariffs, which is not directly related to Nvidia's core business, further supporting the neutral sentiment.
