Stocks are booming despite the Iran war, inflation and the country's dour mood. Here's why.

The S&P 500 has hit nine record highs in May and Goldman Sachs raised its year-end target to 8,000, about 6% above current levels. The rally is being driven by 50% average earnings growth at technology companies, 20% earnings growth ex-tech, and optimism around AI productivity gains, while lower P/E multiples are making equities look more attractive. Risks remain from the Iran war, higher oil prices, sticky inflation, and elevated Treasury yields, but the base case in the article is constructive for stocks.

Analysis

The market is being pulled higher by an earnings revision cycle that is still underappreciated in positioning. When forward estimates are rising faster than price, the multiple can look “cheap” even in a headline-expensive index; that usually keeps passive flows and systematic trend-followers long while active managers remain underinvested. The second-order effect is that this is not just a valuation story — it is a breadth story, because if non-tech earnings are re-accelerating, the rally can broaden beyond the AI complex and reduce dependence on a narrow handful of megacaps.

AI remains the biggest medium-term optionality, but the setup is increasingly bifurcated: the infrastructure leaders can keep compounding even if software monetization is slower than promised. That argues for favoring the platforms with real balance-sheet capacity and distribution moats over the smaller “AI beta” names that need perfect execution. If the market starts pricing in productivity gains without corresponding wage inflation, the winners will be the firms with operating leverage and low incremental capex intensity, not the most speculative beneficiaries.

The main near-term kill switch is rates. A move higher in yields can compress the multiple faster than earnings can grow, especially if the market starts to question whether inflation is proving sticky enough to keep the Fed on hold into the summer. Geopolitics is a catalyst mainly through oil and inflation expectations; if energy rolls over, the market could get a brief “all-clear” rally, but if the conflict drags, the margin benefit from earnings may be offset by a renewed duration shock.

Consensus appears too comfortable with the idea that this is a clean, months-long melt-up. The more interesting risk is that stocks are already discounting both benign inflation and sustained earnings beats, leaving limited room for disappointment in either input. In that regime, upside is still available, but the asymmetry shifts toward tactical longs on pullbacks and relative-value expressions rather than broad outright beta.

Key Decisions for Investors

• Overweight MSFT vs GOOGL for the next 3-6 months: MSFT has cleaner monetization of AI spend and higher tolerance for capex, while GOOGL is more exposed to ad-cycle cyclicality if growth cools; keep a 1.5:1 long/short ratio.
• Add GS on weakness for a 1-2 quarter horizon: if the earnings revision cycle persists, GS should benefit from better capital-markets activity and higher confidence in the macro tape; use a stop if 10Y yields reprice sharply higher and risk assets de-rate.
• Pair long LPLA / short IWM for 3-6 months: if rates stabilize and earnings breadth improves, advice/wealth platforms with sticky assets should outperform small-cap beta, which is more vulnerable to sticky funding costs and weaker pricing power.
• Use SPY call spreads or QQQ call spreads 1-2 months out rather than outright long futures: the market likely grinds higher, but the risk/reward favors defined-risk upside because any yields shock or oil spike can quickly compress multiples.
• Hedge the upside case with a tactical long energy overlay only if oil reaccelerates: if geopolitical de-escalation fails and inflation re-firms, consider XLE as a short-duration inflation hedge against the same risk that would hit growth multiples.
