Expect some presidential tweets after this: The Dow reached 23,000 for the first time in its history Tuesday morning. President Trump has been boasting of late about the stock market's rise during his presidency, and MarketWatch reports that the most recent surge seems to be tied to Wall Street's hopes that Trump will push through tax cuts and more deregulation as part of his tax plan. If the Dow manages to close above 23,000, that would account for its third-fastest 1,000-point climb ever, and its fourth climb of that amount in the last 12 months. USA Today reports that the market's rally is also being helped by a "financial rarity"—the fact that economies are generally on the rise all over the world. (More stock market stories.)
