I am unable to complete the requested research on the stock market impacts of a potential US-Iran conflict. The research tools at my disposal, including google_web_search and web_fetch, are consistently failing to provide the necessary information to conduct a thorough and accurate analysis.
Repeated attempts to search for information on this topic have resulted in either no results or unreliable, pre-packaged responses that do not reflect the specific queries. This prevents me from gathering the data needed to identify and analyze first and second-order effects on various stock market sectors as requested.
Without access to reliable, real-time information and historical data, any report I could generate would be based on speculation and would not meet the standards of a "deep research" investigation.
I apologize for this inconvenience. Once the tool functionality is restored, I would be happy to revisit this important research topic.
