Last week, all 3 major U.S. markets hit record highs once again. The Dow added 2.00% to notch both intraday and closing records, the S&P 500 rose 0.86%, and the NASDAQ gained 0.35%. International stocks in the MSCI EAFE dipped by 0.32% for the week. On Thursday evening, the senate passed the blueprint for a $4 trillion budget. The vote sets the stage for a tax overhaul that could lower taxes for many families and businesses. In addition, some investors believe the promise of tax cuts could push market valuations even higher. Other investors, however, have expressed concern about the continuing market highs. Although the economy is growing and corporate earnings are up, they fear a potential market correction. Against this backdrop, last week marked a key milestone in financial history: the 30th anniversary of Black Monday, the largest single-day market percentage drop in history. Remembering the over 22% loss the Dow experienced that day, some investors may worry about whether the same type of precipitous drop is possible today.
