- Strong Market Performance: During Trump's first term, the Dow Jones Industrial Average surged by 57%, the S&P 500 rose by 70%, and the Nasdaq Composite skyrocketed by 142%, indicating robust market performance that reflects investor confidence in economic policies.
- Impact of Interest Rate Policy: The Federal Reserve's ongoing rate-easing cycle has facilitated corporate borrowing, leading to increased hiring, acquisition activity, and capital investment in innovation, thereby bolstering corporate earnings growth and reinforcing the bull market foundation during Trump's presidency.
- Tax Policy Effects: Trump's Tax Cuts and Jobs Act lowered the peak corporate income tax rate from 35% to 21%, resulting in cumulative stock buybacks by S&P 500 companies exceeding $1 trillion in 2025, which has boosted earnings per share and enhanced stock attractiveness to value-seeking investors.
- Valuation Risk Warning: As of March 2, the Shiller P/E ratio reached 40.02, and historical data indicates that a ratio exceeding 30 typically precedes significant market declines, suggesting that the current bull market may be facing unsustainable risks.
