Market Update

Thanks to the Fed’s series of rate hikes in 2022 and 2023, inflation has cooled significantly from its post-pandemic highs, drawing closer to the 2% goal. This disinflation has occurred without severely impacting economic growth, suggesting the success of a soft landing. The stock market thrived in 2024, spurred by recent rate cuts (0.5% in September and 0.25% in November), and a notable surge followed Donald Trump’s presidential election win in November, propelling indices to historic highs. Nonetheless, the outlook for 2025 remains clouded by potential trade policy changes and corporate tax discussions, which could impact business confidence and growth. The path forward holds both optimism and caution as new policies take shape.
