Why Choose US Stocks: Understanding the Underlying Logic and Practical Path to Long-Term Allocation Value at the Juncture of Earnings Season and Interest Rate Decisions

In late October each year, the US stock market enters a period of extremely high information density: on one hand, Q3 earnings season begins intensive disclosure, with numerous blue-chip companies releasing their results; on the other hand, the Federal Reserve's interest rate meeting approaches, and the market's maneuvering over the interest rate path intensifies, leading to simultaneous amplification in index volatility and sector rotation. While short-term market movements naturally attract attention for global investors, a more critical question is: Has the underlying logic of the US stock market as a core asset in global asset allocation changed at this juncture? How should individual investors leverage this situation to optimize their portfolios? This article will systematically re-examine the classic proposition of "Why choose the US stock market" from three perspectives: structural advantages, the current market node, and practical strategies. I. Three Structural Advantages: The Underlying Source of Long-Term US Stock Market Returns When discussing the allocation value of the US stock market, one cannot look only at short-term gains or losses, but must examine the structural factors that support its long-term returns. These factors transcend economic and policy cycles, representing the fundamental difference between the US market and other markets. 1. The World's Deepest Market Depth and Liquidity The US stock market concentrates the group of listed companies with the highest global market capitalization, covering almost all major industries such as technology, finance, healthcare, energy, consumer goods, and industry. Deep market depth means that investors can complete initial positioning and rebalancing at low costs, regardless of the capital size. Furthermore, the developed options and derivatives system provides rich tools for risk management. For cross-border capital, the ability to enter and exit with controlled costs—this liquidity advantage is difficult for most single markets to replicate and is the primary reason for the long-term concentration of global capital. 2. Listed Company Quality and Shareholder Return Culture The long-term returns of the US stock market fundamentally stem from sustained corporate earnings growth and a mature shareholder return culture. S&P 500 constituents have maintained a tradition of stable dividends and share buybacks over the long term, with buybacks often acting as a "counter-cyclical stabilizer" during periods of stock price stagnation. Moreover, the open listing mechanism in the US stock market for emerging industries that are not yet profitable allows leaders in cutting-edge fields to gain market pricing early. This gives investors the opportunity to share the complete dividends of industrial transformation, rather than just the tail end of maturity. 3. Relatively Complete Information Transparency and Regulatory Rules Strict information disclosure requirements, a mature delisting mechanism, and investor protection systems collectively form the "trust infrastructure" of the US stock market. For overseas investors, transparent rules significantly reduce the additional risks associated with information asymmetry and provide a more reliable ground for long-term investments based on fundamental research. This is particularly important for individual investors who lack the time and energy to scrutinize individual stocks. II. The Special Nature of the Q4 Node: Why Interest Rate Decisions and Earnings Matter Earnings Season: A "Physical Examination" to Test Profit Resilience The significance of the Q3 earnings season lies in providing two lines of observation: first, the performance of corporate earnings itself, including revenue growth rate, margin changes, and management guidance for the next quarter; and second, management's assessment of the macroeconomic environment, particularly changes in capital expenditure plans and hiring intentions. The combination of these two indicators can essentially sketch the true temperature of the US economy. For long-term allocators, the meaning of earnings season is not about chasing short-term volatility from individual outperforming stocks, but about verifying whether the core assumption of "US corporate earnings resilience" in US stock long-term allocation still holds true. If earnings quality is solid, then short-term emotional fluctuations are more likely to be noise. Interest Rate Meetings: The Re-pricing of Valuation Anchors Interest rates are the anchor of asset valuation. As interest rate meetings approach, market expectations regarding the interest rate path are directly reflected in index fluctuations and style shifts: growth stocks are more sensitive to future cash flows, thus reacting more dramatically to interest rate changes; defensive sectors are favored by capital when uncertainty rises. The tug-of-war between defensive and growth styles observed since October is essentially a manifestation of this game. It must be emphasized that for long-term investors, the importance of a single interest rate decision is far less than the long-term trend of interest rates; this trend truly determines the long-term discount rate of assets and is the anchor of the valuation system. III. Practical Paths for Retail Investors in US Stock Allocation Having understood the logic, the operational level can follow these time-tested principles: * Base Allocation with Broad Market Indices: For most investors, broad market index products such as the S&P 500 or Nasdaq 100 serve as the base position in the portfolio, providing average returns from the US stock market with the lowest cognitive cost, while naturally diversifying the risk of individual stock failures, making it the first step for beginners. * Core-Satellite Strategy to Enhance Returns: On top of the index base, a portion of the position can be allocated to superior industries or individual stocks that the investor deeply understands, but a cap must be set on the position size for a single stock to prevent "betting" from eroding portfolio stability. * Phased Accumulation and Dollar-Cost Averaging to Smooth Volatility: Instead of trying to predict short-term peaks and troughs during high-volatility periods, it is better to smooth costs through phased buying or regular fixed-amount investments, delegating the timing dilemma to disciplined execution. * Attention to Exchange Rate and Tax Factors: When non-US investors allocate to US stocks, fluctuations in the USD exchange rate significantly affect the final return denominated in the local currency, so they can decide whether to hedge based on the attributes of their income currency; simultaneously, understanding the tax treatment of dividend withholding tax and capital gains in advance can reduce unnecessary losses. * Maintaining Emergency Cash and Rebalancing Discipline: US stocks trending upward long-term does not mean a smooth path; retaining liquidity reserves and regularly rebalancing according to established rules is a key action to navigate cyclical volatility. IV. Clarity Below the Nodes: Coexistence of Opportunities and Risks Of course, choosing US stocks does not mean ignoring risks. The current market still faces several uncertainties: the divergence in the interest rate path has not been fully converged, and whether the high valuation of the AI sector can be continuously realized through earnings still requires verification from earnings reports; geopolitical and policy variables may also cause periodic shocks to risk appetite. Precisely because of this, the correct posture for allocating to US stocks is not a one-time full-position bet, but a long-term discipline built on clear understanding. Regarding the question of why to choose US stocks, the answer is never found in the performance of a single quarter, but rather in the long-term certainty built from market depth, corporate quality, and the institutional environment. The volatility brought by earnings season and interest rate meetings actually provides prepared investors with a calmer entry rhythm and more opportunities for thorough information verification. For investors aiming to optimize asset allocation globally, every significant pullback in Q4 might be worth adding to a watchlist rather than a fear list—this is both a methodology for long-term investing in US stocks and a gift volatility offers to the patient.
