The stock market’s euphoria is reaching a fever pitch, yet America’s optimism has continued to grow. According to our latest Bear or Bull survey, 71.5% of respondents remain bullish heading into December, up from 61.7% last month. This confidence comes as international capital flows into US markets at record rates, with consumer confidence also reaching a 16-month high in November, reflecting growing economic optimism.

• In November, the S&P 500 recorded its highest monthly gain of the last 12 months at 5.7%, while the tech-heavy Nasdaq surged by 8.34% over the past month.
• US shares now represent nearly 70% of the leading global stock index, up from 30% in the 1980s, with foreign investors channeling an annualized $1T into US debt securities.

Forward-looking: Despite investor optimism, experts warn of stretched valuations and the potential for a market bubble. Rockefeller International’s Ruchir Sharma cautions that the US market is “over-owned, overvalued, and overhyped to a degree never seen before.” He points out that, unlike previous booms, the current surge is pulling capital from other markets, which could lead to a significant correction. Meanwhile, Carson Group’s Ryan Detrick expects a “choppier” third year of the bull market in 2025, though he remains optimistic about continued record earnings and strong profit margins. This disconnect between sky-high valuations and mounting concerns suggests that investors may need to brace for increased volatility ahead.
