The provided evidence strongly supports that Trump praises record-high stock markets, particularly when he is president or president-elect. Multiple sources from 2024 and 2025 explicitly link him and his administration to celebrating market booms, such as a White House article titled 'Trump Economy Ignites... Market Boom' and a BBC report of him 'ring[ing] bell on record stock market'. However, there is also evidence from 2023 showing him criticizing a record high that occurred under a different administration, suggesting his praise is context-dependent and tied to his political position.
