SK Hynix and Samsung Crashed While Korea Was Closed — What Actually Matters Monday

Not financial advice — this is my own morning prep, shared. Numbers are as of Thursday’s close and move fast. Verify before acting.

The one-minute read

Markets closed higher Thursday despite a flare-up in U.S.-Iran tensions, as a semiconductor rally and falling oil prices outweighed geopolitical risk. Underneath the calm, the 10-year Treasury yield pushed to a two-month high and mortgage rates kept drifting up — worth watching for spillover into rate-sensitive sectors like housing and homebuilders.

Overnight & pre-market

• S&P 500: 7,543.64 (+0.81%)
• Nasdaq Composite: 26,206.89 (+1.30%)
• Dow Jones: 52,487.41 (+0.27%, +139 pts)
• 10-yr Treasury yield: 4.56%–4.59% (highest since mid-May)
• Fed Funds target range: 3.50%–3.75% (held since June FOMC)
• 30-yr mortgage avg: ~6.5%–6.7%, trending up this week
• 15-yr mortgage avg: ~5.8%–6.1%, trending up this week

Movers worth noting

• NVDA +3.7% — reports that China may allow its major AI companies to buy a limited number of H200 chips
• PEP — earnings missed estimates as U.S. consumers tighten their budgets
• LEVI — beat quarterly expectations, raised guidance and dividend

Today’s economic calendar (ET)

• On the radar: June CPI report — Tuesday, July 14 (last major inflation read before the Fed’s July decision)
• On the radar: FOMC meeting — July 28–29 (no updated projections/dot plot)

On my watchlist

Rising Treasury yields and creeping mortgage rates are the thread to pull on — both are reacting to Middle East-driven oil price moves rather than a shift in Fed guidance for now. Watching whether that persists into next week’s CPI print. No major U.S. data today, so headline risk (Iran, oil) is likely to drive the tape more than the calendar.

Bottom line

Modestly risk-on: equities shrugged off geopolitical headlines and chip stocks led, but rising yields and mortgage rates are a quiet counter-signal worth tracking. Nothing here changes the picture until the June CPI print on July 14 or a material escalation out of the Middle East.

Numbers above were accurate as of publish time and are illustrative of my own process, not a recommendation. Markets involve real risk.

I don’t usually write about what billionaires are doing. It’s the laziest content on the internet — “Buffett bought X, so buy X” — and it’s made more people poor than rich.

But this one is different, because it’s a contradiction, and contradictions are where the actual lesson lives.

Here’s the setup. A 95-year-old man sat down with CNBC on July 15 and basically said there’s nothing worth buying in this market. His company is sitting on the biggest pile of cash it has ever held. And in the same interview, he volunteered that he personally started a $31 billion position in Google.

Both of those are true. Let’s do the math on why.

Fact 1: he really is sitting on the sidelines

Berkshire Hathaway ended Q1 2026 with $397.4 billion in cash and short-term Treasury bills — an all-time record, past the previous $381.7B high from Q3 2025. Roughly $52 billion of that is actual cash; the rest is parked in T-bills.

That detail matters more than the headline number. That money isn’t sitting in a mattress losing to inflation. It’s lending short to the U.S. government and collecting interest every single month. Which means waiting costs him almost nothing. He can say “no” for three straight years and still get paid to say it.

And he’s been saying no. In Q1 alone Berkshire sold $24.1 billion of stock and bought $16 billion — a net $8.1 billion of selling, in Greg Abel’s first quarter as CEO. Apple, once close to half the equity portfolio, is down to roughly 22% of it — still the largest holding by far, just half the weight it used to carry.

Fact 2: why he says there’s nothing to buy

Buffett’s language in the interview was blunt: it’s hard to find value when everybody around you would rather gamble. He’d used the same frame at the May shareholder meeting, describing the market as a church with a casino attached.

That metaphor is doing real work, so let me unpack it the way I’d explain it to my wife over coffee:

• The church crowd buys a business. They’re asking what this company will earn over the next ten years, and whether today’s price is cheap against that.
• The casino crowd doesn’t look at the business at all. They’re betting on whether the number goes up today.

His complaint isn’t that the casino exists. It’s that the casino got so attractive that church people keep wandering over. He singled out same-day options — contracts that settle by the closing bell — and said flatly that’s not investing and it isn’t even speculating. It’s gambling.

Here’s the mechanism that actually matters: money that only cares about today doesn’t care what a company earns in 2036. When enough of that money floods in, prices start moving independently of the underlying business. The company is the same as last year; the stock isn’t.

Run Buffett’s one ruler — is this price cheap against the next decade of earnings? — against a market priced by people who aren’t thinking about the next decade, and everything comes back expensive. Not some things. Everything. That’s how you end up with $397 billion and nothing to spend it on.

I feel this one personally, by the way. I sell cash-secured puts. I’m not going to pretend I’ve never been on the casino side of the room. [ADD YOUR OWN LINE — one honest sentence about a trade where you were betting on the move, not the business.]

Fact 3: the one exception

Now the part that broke people’s brains.

Berkshire first showed an Alphabet position in its Q3 2025 filings, and it’s grown ever since. The stake is now north of $31 billion — behind only Apple and American Express. Less than a year in, and it’s already a top-three holding.

Everyone assumed this was Greg Abel’s fingerprint. New CEO, new era, tech bet, makes a nice story. Becky Quick asked him directly whose idea it was.

Buffett’s answer: “I initiated it.” He added that he isn’t doing anything Abel doesn’t approve of and vice versa — but that Abel is the decider going forward.

So the man who says the market is a casino personally started a $31 billion position in a company shoveling hundreds of billions into AI. That’s the contradiction. And it dissolves the second you look at when he bought.

The order of operations is the whole story

Most people only saw the $10 billion headline from June. But roughly $21 billion of that stake was accumulated before it, starting Q3 2025 — at open-market prices, no discount, no special terms. Same prices you and I could have paid.

Then in June, Alphabet announced an $84.75 billion equity raise (upsized from $80B after demand ran hot), and Berkshire took $10 billion of it as a private placement: Class A at $351.81, Class C at $348.20 — modestly below where the stock was trading.

Read that sequence again. He didn’t buy because he got a deal. He got a deal because he was already buying. The discount was a tip, not the meal.

Why Google needed the money at all

This part genuinely surprised me, so here are the numbers straight from Alphabet’s own filings and reporting:

• Operating cash flow for the year ending March 2026: about $174 billion
• Planned 2026 capital expenditures: $180–190 billion — and management says 2027 goes higher
• 2022 capex, for scale: about $31 billion

So one of the most profitable companies on earth is planning to spend more on data centers and AI chips in a single year than its entire operating cash flow. It had already issued over $85 billion of debt in the prior year. Still not enough — hence selling stock.

Issuing stock isn’t free money, by the way. There’s no interest and nothing to repay, but every new share thins out the slice existing owners hold. Same pie, more forks. Google accepted that trade anyway. That tells you how badly it wants the compute.

The 2008 comparison that changed my read

Here’s the detail that made this click for me.

When Buffett put $5 billion into Goldman Sachs during the 2008 crisis, he didn’t buy common stock. He took preferred shares paying a fat dividend, plus warrants to buy more later at a set price. He built himself an airbag. He wasn’t betting on Goldman so much as on his own terms.

This time? Plain common stock. No preferred, no warrants, no dividend guarantee — and notably, the same Alphabet raise did include mandatory convertible preferred shares, which went to public investors rather than to him.

He took the simplest, least-protected instrument available. You only do that when you think the business itself is going to be fine.

But he hedged, and the hedge is the important part

Buffett didn’t sell this as a slam dunk. Two caveats came straight out of his mouth:

One: he said he doesn’t like Alphabet as much as at least four or five other businesses Berkshire owns. That’s a ranking statement, not a rejection — he’s comparing it to wholly-owned operating businesses.

Two: on the AI arms race, he pointed out that everyone is pouring hundreds of billions in, and that’s real money.

That second one is the crux. The spending is certain. The return is not. Money leaves the account this year; whether it comes back as revenue is unknown. That asymmetry is the exact trade Buffett has spent seventy years avoiding.

So the honest summary of his position: high confidence in the company, open question on the AI math.

Now the pushback — because “Buffett bought it” is not a thesis

“His cash pile means a crash is coming.” I don’t buy it. He was at $381.6 billion back in Q3 2025 and the market went on to make new highs. Cash isn’t a prediction, it’s readiness. Treating it as a crash clock could keep you out of the market for years. [LINK — related Hebojago post on market timing]

“So I should just buy Google too.” Notice what actually happened: about two-thirds of his position was bought at ordinary market prices, like anyone could. His edge wasn’t access. It was being early and being willing. That’s not a thing you can copy after the news breaks.

“He’s not even CEO anymore.” Half true. Abel is the decider now, and Buffett said so plainly. But Buffett also said he started this one himself and that neither acts without the other’s approval.

“Buffett bought it, so it’s safe.” This is the one I want to be loud about: no. In 2011 he put about $10.7 billion into IBM — roughly 64 million shares near $170. He sold out over 2017–2018 in the $140s. Over that stretch IBM fell while the broad U.S. market roughly doubled. Someone who ignored him and bought an index fund did dramatically better. He is allowed to be wrong, and he has been, in this exact category.

The chart bit — take it lightly

The video I built this from made a technical argument I want to flag rather than assert: Alphabet had been capped by a descending trendline for months, broke above it on July 15 (the interview day) with a ~3% move, then gave it back on July 16 on Gemini-related news.

I checked directionally and the July 16 drop is real. The precise levels and moving-average claims I could not fully verify, so treat them as the video’s read, not as fact. If you care about that stuff, the only question worth asking is whether a broken level holds when it’s retested. Everything else is storytelling.

What I’m actually watching, in plain terms

Two numbers, both public, both free:

1. Does Berkshire’s cash pile start shrinking? It’s disclosed every quarter. If $397.4 billion starts dropping, it means he found something. That’s a far better signal than any prediction.
2. Does Alphabet’s AI spending show up as revenue? Cloud revenue growth in the quarterly report is the scoreboard. Buffett’s one reservation was that the outflow is certain and the inflow isn’t. Several quarters of that converting means his caution was misplaced. Several quarters of it not converting means it wasn’t.

The takeaway I keep coming back to isn’t about Google at all. It’s that investing isn’t a game of guessing better than everyone else. It’s a game of not buying when there’s nothing to buy, and buying when there is. A guy who held $397 billion for years and then wrote one $31 billion check is a live demonstration of both halves.

Not financial advice — I’m a software developer who writes about his own money, not an advisor. Every figure here was verified against CNBC’s July 15, 2026 interview coverage, Berkshire’s Q1 2026 disclosure, and Alphabet’s June 2026 SEC filings as of July 18, 2026, and is subject to change; anything I couldn’t confirm is labeled as unverified above. Copying a billionaire’s trade is not a strategy — his time horizon, tax situation, and downside tolerance are nothing like yours or mine.
