The Indices Are at Records Because of Oil - AMD and SpaceX Are Irrelevant

The headline says the Dow and S&P 500 are hitting new all-time highs despite AMD and SpaceX tumbling after earnings. But that framing is backwards - it treats the two name-specific selloffs as some kind of stress test the market is "surviving," when in fact neither company's move has anything to do with why the indices are going up. The record highs are driven by a geopolitical event that shifted the oil risk premium, not by earnings quality or broad-based strength. And once you understand what's actually pushing these indices higher, you understand why the rally is mechanically fragile.

Here's what happened. Treasury Secretary Scott Bessent told CNBC early Tuesday that he believes a deal to reopen the Strait of Hormuz could happen "today or tomorrow." Brent crude, the global oil benchmark, dropped 5.3% to $79.36 a barrel. West Texas Intermediate also fell sharply. The S&P 500 surged 1.79% to a record close of 7,737. The Dow jumped 1.71% past 54,000 for the first time. The Nasdaq Composite added 2.59%. The S&P had its best day since April. The Dow had its best day in almost two months.

This is a classic oil-offside-day trade. When energy prices drop on geopolitical de-escalation, the broad market rips because lower oil cuts inflation expectations, which improves the outlook for consumer spending, corporate margins, and the Fed's willingness to hold - or cut - rates. The mechanism is simple: cheaper energy flows through the entire system as a margin tailwind. The index records are the downstream effect, not evidence of fundamental health.

Now let's look at the plumbing. SPY options show implied volatility at 13.64%, which is the kind of number that signals a market with no fear. There's a lot of complacency baked into that reading. The put-to-call volume ratio on SPY is 0.72, meaning more call options are being bought than puts - that's bullish sentiment. But the put-to-call open interest ratio sits at 2.30. That means for every call contract outstanding, there are 2.3 put contracts sitting on the books. There is a massive wall of puts underneath the current price level, and dealers holding those positions need to hedge by selling into weakness. Understanding what I understand about gamma regimes, the combination of low implied vol and heavy put open interest tells me dealers are likely sitting with positive gamma at-the-money, which suppresses volatility and creates mean-reverting behavior - as long as price stays in range. If it breaks down through that put wall, dealers get flipped into negative gamma, and the mean-reverting regime turns into a momentum regime, which means every sell order gets amplified.

The S&P 500's 20-day volatility is sitting at just over 1%. That's low. The RSI is 66, approaching overbought territory but not there yet. SPY is trading well above both its 50-day moving average at $745.89 and its 200-day average at $701.39. The setup looks strong on the charts. But chart strength in a positive-gamma regime is a function of dealer hedging, not conviction buying. Once gamma flips, chart support tends to break faster than fundamentals would suggest.

Now, about AMD and SpaceX, because the headline wants you to think their selloffs are somehow relevant to the index record.

AMD reported $11.5 billion in revenue for the quarter ended June 27, beating the $11.3 billion FactSet estimate. Data-center revenue doubled to $6.7 billion, now representing 58% of AMD's total - up from 42% a year ago. Net income came in at $2.3 billion against a $1.7 billion estimate. The company posted its fifth consecutive quarter of record processor sales. And the stock fell 6% to 8% in after-hours trading. Why? Because Elon Musk committed to Nvidia chips for SpaceX. One sentence from the earnings call, and the market decided AMD's AI trajectory is capped by a customer whose biggest shareholder also happens to be picking its competitor.

SpaceX reported its first earnings as a public company - the company raised $85.7 billion in its June IPO, the largest in history, at $135 a share. Revenue was $7.8 billion, well above the $6.8 billion estimate, up 92% year-over-year. The net loss narrowed to $541 million from $1 billion a year ago. Starlink now has 12 million subscribers and generated $1.66 billion in operating profit. And the stock fell roughly 8% to 11% after hours. Why? Because capital expenditures hit $18.4 billion for the quarter, against a $13 billion estimate. The market read through the revenue beat and focused on the cash burn - a company that just went public is spending $73 billion annually on infrastructure, and investors started doing the math on how much equity dilution or debt that requires.

Both stories are name-specific. Neither one explains the S&P 500 hitting a record. AMD is a tiny weight in the S&P 500, and both have zero weight in the Dow. The index records are about oil, Hormuz, and the macro relief trade.

But here's where the Hormuz deal gets complicated. The reported framework - Iran controls the northern route for inbound traffic, Oman controls the southern route for outgoing vessels, 60-day ceasefire, no tolls - comes with a truckload of caveats. It does not include any agreement on Iran's nuclear program, which was reportedly the top priority. Iran denied the strait would reopen immediately, saying it depends on "a change in U.S. behaviour." The Houthis, Iran's Yemeni proxy, attacked another Saudi ship in the Bab al-Mandeb on Tuesday morning, their eighth strike on Saudi vessels. There is no indication the deal includes opening the Red Sea route.

This is the kind of thing that looks like a catalyst on the way up and a non-event on the way down. If the Hormuz deal holds and oil stays in the low $80s, the rally has legs. If Iran walks, or the Houthis escalate, or the market realizes this is a partial framework with no nuclear component, the oil risk premium comes back. And when it does, the positive-gamma regime that's been suppressing volatility gets tested against that 2.3x put wall. The conditional chain is straightforward: if Hormuz de-escalation holds, equities have a tailwind. If it frays, the mechanics that are hiding the downside risk today - low IV, heavy put OI, concentrated recent gains - work in reverse.

Let me be clear about the concentration question too, because this matters. The S&P 500 is up 4.1% over the last five days. The equal-weight S&P, which the RSP tracks, is up only 1.2% over the same period. The push to record highs is concentrated. Year-to-date, the equal-weight has actually outperformed - RSP is up 14.97% versus SPY's 13.11% - which tells me the market has had decent breadth over the full period. But the five-day move to records is not broad. The mega-caps are doing the heavy lifting again, and when dispersion narrows this sharply into a record, the index is fragile. It only needs the leader to stumble.

The earnings backdrop is supportive - 86% of S&P 500 companies that have reported so far beat on EPS, according to FactSet, and the blended earnings growth number is the highest in some time. Caterpillar jumped 5.6% on earnings, raising its revenue forecast as AI data center construction boosts demand for its equipment. Palantir soared 17% after beating and raising guidance. But earnings quality and plumbing are two different things. You can have a great earnings season and still get caught in a liquidity regime shift. Same earnings. Same fundamentals. Different impact - because the funding source matters more than the headline.

What I'm watching: the Strait of Hormuz story over the next 48 to 72 hours. Oil prices are the trigger. If Brent stays below $82, the current regime holds - positive gamma, suppressed vol, mean-reverting price action. If oil spikes back above $90, which is only a 13% move from current levels, the gamma flip becomes possible, and that put wall of 2.3x the call open interest on SPY stops being academic and starts being a mechanical reality. Dealers who were hedging into a floor start hedging into a cliff. And the SPY RSI of 66, which looks healthy today, would look like a warning signal in retrospect.

For AMD, the Nvidia-headwind concern from the SpaceX comment is a real competitive risk, but the stock is already bouncing back - it's up 7% today to $518.58 after yesterday's after-hours sell-off. The data-center story is intact: 58% of revenue now, doubling year-over-year. The question is whether the market's concern about Musk's chip choice is a temporary overreaction or a structural re-rating of AMD's AI addressable market. I don't know the answer to that yet.

For SpaceX, the capex number is the real concern, not the revenue beat. $18.4 billion in quarterly capex on $7.8 billion in revenue means the company is spending more than double what it earns. The lockup expiration later this week frees up more than $100 billion in shares for trading, which is a mechanical overhang that has nothing to do with fundamentals. IPO lockups are a plumbing issue. When $100 billion in shares suddenly become tradable, there's a liquidity imbalance, regardless of whether the business is growing 92% year-over-year.

None of this changes the fact that the indices are at records. Yes, we could still go higher. The bubble case is 25 times 12-month forward earnings, which puts you somewhere around 7,900 on the S&P. But do you really want to play for another couple hundred points when the plumbing shows low volatility, heavy put concentration, and a geopolitical catalyst that hasn't been confirmed? I don't know if the answer is yes or no yet. But I do know that the move we just had is about oil and dealer positioning, not about the quality of American earnings. And when the move is about mechanics, it can reverse just as fast.
