Backtest the impact of Mitsubishi Corp with Earnings Release Date, from 2022 to now.

I attempted to run an event-backtest using the earnings-announcement dates I extracted for Mitsubishi Corporation, but the price-retrieval step failed because the system could not recognise the ticker symbol I supplied. For Japanese equities the platform sometimes expects a specific symbol format (e.g. “8058”, “TYO:8058”, or the US-ADR symbol “MSBHF” / “MITSY”), and the error message indicates the one I tried (“8058.T” and “8058”) did not match the internal database. To proceed I need to know which ticker format our data source recognises for Mitsubishi Corporation. Could you confirm one of the following (or provide the correct symbol you normally use on this platform)? 1. Tokyo Stock Exchange: • 8058 (plain code) • TYO:8058 (exchange-prefixed) 2. U.S. ADRs: • MSBHF (OTC) • MITSY (OTC) Once I have the correct symbol I’ll rerun the event back-test and present the performance results.
