War Economy Playbook: 5 Sector Bets as Iran Conflict Hits Week 2

Thirteen consecutive nights of US airstrikes on Iran. Oil physically trading near $110 per barrel. A war that has already cost the Pentagon $37.5 billion. New Section 301 tariffs hitting 68 economies at 10-12.5%. If you think the only play here is buying defense stocks and praying, you are leaving a lot on the table.

The macro picture is genuinely ugly in the way that creates opportunities if you know where to look. Warren Pies of 314 Research is calling for an overweight in both commodities and equities, specifically flagging that the oil surge is supply-driven, not demand-driven, which means wage growth is still decelerating and a Fed rate hike would be a policy mistake. Wharton's Jeremy Siegel agrees, noting that WTI has moved from $70 to $90 (and physical markets are pricing it even higher) and that hawkish dissents at the upcoming FOMC meeting are a real risk. The Fed is caught between a supply shock it cannot control and an economy that does not need tighter money right now.

Against that backdrop, here is where social sentiment and earnings data are pointing this week. $SLB was the top S&P 500 gainer on Thursday, up roughly 11% after a Q2 EPS and revenue beat with broad-based international growth. Energy services names benefit directly from sustained high oil prices incentivizing drilling activity globally. $RCL is not the story here, but $RNG (RingCentral) absolutely is: the stock jumped nearly 30% intraday after beating Q2 and raising its full-year adjusted earnings forecast. It is up 70% year to date with 12% short interest, which means a squeeze is still very much on the table for anyone who missed the initial move.

On the enterprise software side, $SAP reported accelerated cloud revenue growth with 90% of cloud deals including AI components. The SaaS apocalypse narrative that hammered SAP stock by roughly 38% year to date is cracking. CEO Christian Klein's argument, that LLMs lack business process knowledge and domain logic and therefore need SAP rather than replace it, is landing with institutional buyers. State Street's Global CIO Lori Heinel, who oversees $5.7 trillion in assets and took in a record $180 billion in inflows in 2025, is advocating for exactly this kind of broadening: small caps, emerging markets, Europe, developed ex-US. The concentration trade in large-cap US growth is getting stress-tested right now.

The wildcard nobody is pricing cleanly is the tariff layer on top of the war. New Section 301 tariffs at 10-12% across 68 economies, with the EU specifically targeted over Apple and Meta antitrust fines, means the stagflation scenario the Fed has been trying to avoid gets meaningfully more plausible. Ed Yardeni's FIMO thesis (Fabulous Earnings Momentum driven by AI) is the bull case that keeps this market from rolling over entirely. But even Yardeni would admit that $37.5 billion in war costs, a Hormuz choke point with Saudi tankers already turning back, and a World Bank economist warning of global growth collapsing to 1.3% in 2026 is a lot of headwind to momentum trade through.

The market that churns while the news screams is usually the one that surprises everyone when the smoke clears. Watch the Closing Bell recap's signal closely: the S&P 500 finished essentially flat with 364 names gaining ground even as the index printed red on tech weighting. That breadth is not what a market top looks like. It looks more like one that is digesting bad news and waiting for a catalyst to go either way, and right now the next catalyst has a very good chance of wearing a uniform.
