The Bull Market Will Keep Running: Here Is Why

The S&P faces headwinds from inflation, interest rates and increased equity supply, while strong earnings growth supports a bullish outlook. Historical rate-hike cycles have produced mixed market performance; current moderate hikes give the Fed some flexibility and do not guarantee a bear market.

Analysis

The key market question is whether earnings can absorb a higher discount rate and incremental share supply—not whether rate hikes have historically coincided with bull or bear markets. The bullish case is most vulnerable if profit growth is concentrated in a few large firms, revisions broaden lower, or nominal sales growth fails to convert into margins and cash flow. In that setup, index-level earnings strength can mask deteriorating market breadth, while new issuance and reduced buybacks increase the shares the market must absorb.

Over days to weeks, inflation surprises and Treasury supply can move equity multiples before earnings estimates adjust; a rates-led selloff alone is not evidence that the earnings thesis has failed. Over 1–3 months, track real yields, earnings revisions and breadth alongside issuance and buyback activity. Over 6–18 months, persistent higher financing costs could pressure refinancing-sensitive businesses and shift capital toward firms with durable cash generation. The contrarian risk is treating “moderate hikes” as protection: markets can reprice sharply if inflation keeps policy restrictive longer than expected. Conversely, a rally based on earnings may be underappreciated if estimate breadth improves while real yields stabilize.

Key Decisions for Investors

• Keep broad S&P exposure near strategic weights rather than making a large directional bet on the article’s mildly bullish case. Add tactically after a rates-driven pullback only if forward earnings revisions and market breadth remain stable or improve.
• Use a defined-risk SPY put spread as a temporary hedge around major inflation or Fed catalysts only if implied volatility and hedge cost are acceptable; the article provides no pricing or volatility data to justify a specific structure.
• Monitor real Treasury yields, earnings-revision breadth, aggregate issuance, and buyback activity. A sustained rise in real yields alongside falling revisions and weakening breadth would falsify the constructive view and argue for reducing index beta.
• Do not infer a durable bull market from historical rate-cycle averages. If yields stabilize and earnings breadth broadens, the risk is underexposure; if inflation reaccelerates or cash-flow conversion weakens, earnings support may not prevent multiple compression.
