US bombs Iran and blocks their oil — load up on Chevron and Exxon to ride the crude spike

Verdict: the crude playbook is real, but the trigger hasn't fired — wait for it

**Verdict: worth waiting for, not buying today.** The strongest case for this idea is empirical: on the exact rule set, the 60-month CVX backtest compounded 80.2% across 23 trades — with a poor 39.1% win rate and a 16.2% maximum drawdown, meaning the fat right tail does the work — and the most recent 12-month window returned 26.0% on 5 trades with a 60% win rate. Chevron's Q2 2026 fundamentals also inflected the thesis's way: gross margin jumped to 45.5% from 40.6% and net margin to 18.0% from 4.6%, with FY2025 free cash flow of $16.6B in the 99th percentile of 95 energy peers. The strongest case against is what's beneath the price: filings for the quarter ended June 30, 2026 show roughly $147.3M of net open-market insider selling at Chevron across 21 holders and about $3.5M at ConocoPhillips, while Chevron and Exxon's FY2025 revenues fell 4.6% and 5.0% year over year with deeply negative EPS growth. Nothing triggers today either — CVX needs a one-day move above 3% (currently -0.5%) and XOM needs both that move and its ADX to reach 25 (currently 1.4), so chasing now means taking a trade its own rules haven't armed. What would flip the verdict: a fresh escalation headline that produces the >3% one-day move on CVX with its ADX trend filter met, arming a mechanical entry — or, in the other direction, a ceasefire that neutralizes the whole premise. The parameter-sensitivity run exceeded its time budget and returned no recommendation, so no robust nearby setup was established; treat the published thresholds as the plan, respect the 2.5% stop, and let the trigger come to you.

Trade now: armed on trend, waiting on the oil gap

Nothing triggers today. The entry needs two things at once: a one-day move above 3% and a 14-day ADX above 25. On CVX, the ADX condition is already met at 27.2 versus the 25 threshold, but the one-day move is -0.5% — about 3.5 points below the trigger — so CVX is one sharp crude-driven up-day away from entry. On XOM, the one-day move is +0.3% (still 2.7 points short) and the ADX is 1.4 versus the required 25, so both legs are far. The setup waits for its entry conditions; today's job is monitoring, not buying. If an entry fires, the risk plan is mechanical: a 2.5% stop loss on the position, a 5% take profit, a hard stop at the 78.6% retracement, and a profit target at the 127.2% extension, with an exit also triggered if price closes below the 10-day Donchian low. That gives roughly 2-to-1 reward to risk per trade, with no position above 25% of capital and about 2.5% of capital risked per position. CVX closed at $212.76, XOM at $165.23, and COP at $136.67. What 'wait' means concretely: set alerts for a one-day close above 3% on each name and for XOM's ADX reaching 25. The evidence base is a completed 60-month backtest on the CVX pair: an 80.2% return over 23 trades at a 39.1% win rate, with a 16.2% maximum drawdown — modest win rate, positive expectancy, which is exactly why you take the mechanical entries rather than pre-empting them. One tension worth flagging before entry: the most recent 13F filings show net open-market insider selling at CVX of roughly $147.3 million across 21 holders and about $3.5 million at COP across 14 holders as of the 2026-06-30 period. Insider selling into a supply-shock rally is not an entry blocker under these rules, but it argues for respecting the 2.5% stop rather than averaging down.

A supply shock with a rules-based engine behind it

The thesis is the classic supply-shock playbook, and the cited news lines it up squarely: Yahoo Finance reported oil jumping over 5% to a two-week high after President Trump said the deal with Iran was 'over', and Bloomberg reported the U.S. striking Iran and blocking its oil sales. CNBC flagged Chevron among the biggest premarket movers. When a major producer's barrels are choked off, integrated majors like Chevron, Exxon, and ConocoPhillips capture the scarcity premium on their own unhindered production. The completed 5-year backtest on this exact rule set gives the thesis empirical footing. Over 60 months on CVX daily bars, 1,237 bars evaluated, the strategy returned 80.2% across 23 trades, with a 39.1% win rate — meaning the tail of the fat right tail does the heavy lifting when oil gaps run. The most recent 12-month window returned 26.0% on 5 trades with a 60% win rate, suggesting the rules performed well in the period closest to today's setup. The fundamentals behind the trade symbols are not stretched. Chevron posted $16.6B of free cash flow in FY2025 — in the 99th percentile of 95 energy peers — and Exxon generated $23.6B, also in the 99th percentile. Exxon's 11.1% ROE sits near the top third of 129 peers, and ConocoPhillips leads the group with a 12.4% ROE and 57% gross margin, both above the sector median. These are cash machines that do not need heroic oil prices to fund their payouts. Q2 2026 internals reinforce the case: Chevron's gross margin expanded nearly 5 points quarter over quarter to 45.5%, net margin jumped 13.3 points to 18.0%, and ROE rose from 1.2% to 6.4%. That is precisely the earnings pattern you want underneath a bet on rising crude — margins already inflecting…
