3 Earnings Movers: Growth, Capex, and the Sell-the-News Trap

The S&P 500 closed at a record high Tuesday. The Dow Jones pushed past 54,000 points for the first time. The Nasdaq, still about 2% below its June peak, surged 2.59%. On the surface, it's a clean rally.

But headlines that say "the market is powering ahead" flatten the action into a single number. What actually moved the market this week wasn't index performance. It was three earnings reports that showed investors three radically different factor profiles — and how the market prices each one differently.

Palantir delivered textbook growth-at-a-reasonable-price execution. SpaceX showed what happens when revenue growth is real but capital intensity is staggering. SanDisk posted numbers that would look incredible on a blank spreadsheet — and got punished anyway.

The comparison set is the point. Here's how each one reads through the five-factor stack: valuation, growth, profitability, safety, and momentum.

1. Palantir (PLTR): Growth and Profitability Intact, Valuation the Only Friction

Valuation — C. Palantir trades at 136 times trailing earnings and 380 times forward earnings. Price-to-sales is 67x. EV/EBITDA sits at 151x. That is not cheap by any definition. But the PEG ratio (price-to-earnings-growth, which divides the P/E by the earnings growth rate) is 0.48, meaning the stock is actually trading below the typical growth-justified benchmark of 1.0. The valuation is expensive in absolute terms but internally consistent with its growth trajectory — which is the GARP test.

Growth — A+. Revenue surged 93% year-over-year to $1.94 billion in Q2, beating the $1.81 billion estimate. The U.S. commercial segment alone jumped 149% to $764 million, and the remaining deal value in the pipeline more than doubled to $6.24 billion. The company raised full-year guidance by $490 million to $8.15–8.16 billion. This isn't a one-quarter blip. U.S. commercial revenue has compounded 380% since 2024.

Profitability — A+. GAAP net income exceeded $1 billion for the first time — $1.06 billion, or 55% margin. Adjusted operating margin was 62%. Free cash flow margin reached 51.5%, with $3.36 billion in FCF over the trailing twelve months. ROIC is 32.6% and ROE is 38.4%. For context, that profitability profile dwarfs most software peers — Datadog, its closest comparable on the NASDAQ, trades at 476x earnings on thinner margins. The margin expansion from 42.8% operating to 62% adjusted reflects stock-based compensation, but even on GAAP, 42.8% operating margin at this scale is exceptional.

Safety — A. $9.2 billion in cash and treasuries, $1.79 billion in debt, a current ratio of 723%. Palantir carries virtually no financial risk. The balance sheet is a fortress.

Momentum — A+. The stock is up 39% over five days, 35% over 20 days. RSI at 72.5 signals overbought conditions, but the MACD is positive at 7.1 and the stock has broken above its 200-day moving average of $152. The momentum is strong but overheated — a timing signal, not a thesis problem.

Portfolio role: Growth sleeve anchor. Palantir belongs in the part of the portfolio that's allocated to AI-adjacent software companies that are actually producing earnings, not just burning cash. The PEG of 0.48 is the anchor metric: if growth sustains even half of its current pace, the valuation self-justifies. What would change this: a sequential slowdown in U.S. commercial growth below 100%, or guidance that misses the raised outlook.

2. SpaceX (SPCX): Revenue Growth Is Real, Capital Intensity Is the Question

SpaceX reported its first earnings as a public company on Tuesday. Revenue of $7.8 billion in the second quarter beat the $6.93 billion estimate and grew 92% year-over-year. The loss narrowed to $541 million from $1 billion a year ago. On a surface reading, that's a clean debut.

The factor stack tells a different story.

Valuation — D. At a $1.68 trillion market cap, SpaceX trades at 73 times trailing sales. EV/EBITDA is 307x. The P/E is negative — the company is not profitable. The market is pricing in $1 trillion in revenue (Elon Musk's stated target), not what the financials currently show.

Growth — A. 92% revenue growth is exceptional. QoQ growth hit 66%. Starlink revenue of $4.29 billion exceeded the $3.83 billion estimate. AI segment revenue of $2.56 billion beat $2.18 billion. The CFO said the company is on pace for $100 billion in annualized recurring revenue by year-end. But here's what matters for the growth grade: $18.37 billion in capital expenditures in a single quarter, more than six times last year. Approximately $15.8 billion of that went to AI infrastructure. When capex grows faster than revenue, the quality of that growth signal degrades because you can't tell how much is organic demand versus capacity investment that may take years to monetize.

Profitability — D. Starlink generated $1.66 billion in operating income — it's the only profitable segment. The AI unit lost $1.26 billion. The space/launch unit lost $542 million. Operating margin is -16.2%. Free cash flow margin is -145%. ROIC is -5.2%. The company burned $33.4 billion in free cash flow over the trailing twelve months against $9.9 billion in operating cash flow. That means every dollar of operating profit went into capex, and then some. The CFO's claim that AI capital deployment achieves "less than a one-year payback" is aggressive and unproven.

Safety — B+. $93.5 billion in cash provides a massive cushion. Net debt is negative $60.7 billion. The current ratio is 512%. But the total debt and finance leases stand at $36.8 billion and are rising. The safety grade holds only because the cash balance from the $86 billion IPO is enormous — it's not structural profitability that's doing the protecting.

Momentum — C. The stock is up 18% over five days but down 12% over 20 days. RSI sits at neutral 50.7. MACD is negative at -8.3. The stock remains 16% below its $150 IPO opening price and 44% below its $225 peak. Year-to-date return is -5.1%. The momentum profile is choppy — buyers and sellers are genuinely divided.

Portfolio role: Speculative barbell hedge. SpaceX belongs in the small-cap or venture-style sleeve of a barbell portfolio, not the core growth allocation. The risk-reward depends entirely on whether the AI infrastructure investments generate returns fast enough to justify $1.68 trillion. The lockup expiration this week, which could make 900 million additional shares available, adds a supply overhang that the factor stack doesn't yet reflect. What would change this: profitability in the AI segment, or Starlink subscriber growth that sustains without further ARPU erosion (it's already declined from $85 to $66).

3. SanDisk (SNDK): Incredible Fundamentals, Stretched Valuation, Classic Sell-the-News

SanDisk reported that data center revenue grew more than 400% in 2026 compared to 2025, doubling in Q4 versus Q3. The company beat consensus estimates and guided Q1 revenue to $10.3–10.8 billion. By most definitions, this was a strong quarter.

The stock fell 9.2% in premarket trading on Thursday and has dropped 36% over 20 days. Why?

Valuation — C+. SanDisk trades at 16 times trailing earnings, which looks cheap — until you check the peer set. Western Digital also trades at 16x, Micron at 20x. Those are not rich multiples for companies with this kind of growth. But EV/EBITDA at 14.2x and price-to-sales at 9x reflect how much the stock has run: up 418% year-to-date, from $43 to a peak of $2,354 before pulling back to $1,228. The PEG ratio of 0.02 is mathematically stunning but reflects a valuation denominator that has been inflated by a parabolic price move. The stock is trading near its 200-day moving average of $872, which means the 52-week trend still supports it — but the 50-day MA at $1,688 is far above, and the stock is well below that level. That gap signals a trend break at shorter timeframes.

Growth — A+. Revenue growth of 175% year-over-year. Sequential growth of 51%. Data center revenue alone grew 400%+ for the year. The gross profit growth was 554% year-over-year. Amazon raised its 2026 capex projection to $220 billion, citing higher memory costs and insufficient capacity to meet demand. The demand fundamentals are real.

Profitability — A+. Operating margin of 61.2%. EBITDA margin of 62%. Free cash flow margin of 56.8%, with $11.5 billion in FCF over the trailing twelve months. FCF growth was 9,678% year-over-year. ROIC of 80.6%. ROE of 91.6%. This is the kind of profitability you see in commodity booms when supply constraints push prices higher. The question isn't whether the margins are real — they are. The question is how long they last.

Safety — A. $4.76 billion in cash, no net debt (debt to equity is 0%), a current ratio of 229%. The balance sheet is clean.

Momentum — D. RSI at 42.2, approaching oversold territory. MACD deeply negative at -125.6. The stock has fallen 36% from its 20-day high and is down from its 52-week peak of $2,354 by more than 48%. 20-day volatility is 11.6%, one of the highest readings in the storage group. Momentum has flipped sharply from euphoric to cautionary.

Portfolio role: Cyclicality play, not a compounder. SanDisk belongs in the commodity-cycle sleeve of a portfolio — the part that profits from supply-demand dislocations and exits before the cycle turns. The fundamental demand signal (Amazon still can't find enough capacity) supports the thesis, but RBC Capital Markets and Summit Insights have both flagged that margins may be near peak levels and that price growth is moderating. Western Digital's downgrade to Hold on August 6, citing upcoming HAMR drive transition costs and expected average-selling-price declines in 2027, reinforces the cyclical risk. What would change this: guidance that shows margins sustaining above 55% for multiple quarters, or evidence that the data center demand curve is structural rather than cyclical.

What the Three Together Tell You About This Rally

The market rally is real — S&P 500 earnings are on pace for 31.1% growth, the highest since 2021. Forward P/E has compressed to 20.4 from 22.2 at the end of 2025. The Strait of Hormuz de-escalation and falling oil prices eased inflation fears. The broad market backdrop is constructive.

But these three earnings reports show you the divergence underneath it. Palantir's factor stack is intact — growth, profitability, and momentum all firing, with valuation as the only friction point. SanDisk's fundamentals are exceptional but its momentum has broken, and the stock is repricing from a cyclical peak toward a more sustainable multiple. SpaceX is the cautionary tale for IPO-driven IPO hype: massive revenue growth that's being swallowed by capital intensity so large that the free cash flow story hasn't begun.

If your portfolio has exposure to all three, the action items are different for each. Palantir rewards patience as long as the U.S. commercial growth rate stays above 100%. SanDisk rewards discipline — hold for the cycle, but watch the margin trajectory closely as the sector enters what could be a peak-pricing environment. SpaceX requires conviction in the AI infrastructure payback timeline, and the lockup expiration is a structural overhang that the market hasn't fully priced in yet.

The rally gives you room to be selective. Use it.
