Indexes

Long-dated Treasury yields set the terms of the session. The 30-year finished at 5.309%, four and a half basis points higher and, per Bloomberg, the highest that bond has carried since 2007; the 2007 peak of 5.44% is now within reach. Equities opened at their best levels and sold off from there — the S&P 500 printed its high of 7,790.68 in the opening seconds and closed within a fifth of a point of its low, off 0.52% at 7,745.06, leaving it 53.93 points under the record close of 7,798.99 set on August 13, a high verified against the index's own session history. What kept the Nasdaq Composite's loss to 0.32% was a violent split inside technology: memory and storage names added between 2% and 9% while software fell hard, Microsoft (MSFT) down 3.04% and Adobe (ADBE) down 3.78%. The VIX rose 6.60% to 15.19 after four sessions under 15.

The S&P 500 closed at 7,745.06, 53.93 points under its August 13 peak.

Sector Heat Map

One sector closed meaningfully higher, and it was the one attached to the barrel.

Technology finished green only because semiconductor weight offset a 2.4% decline across software. The odd reading is staples at -1.64%, normally where investors hide on a down day: Constellation Brands fell 6.19% and Molson Coors 4.75%, and a defensive sector cannot absorb two drops that size. Communication services sat last on Meta's account.

In the News

Rates, FX, Commodities

The long end sold off on supply and policy uncertainty, with no inflation news to blame, which is why the move looks stubborn. Bank of America's Mark Cabana told Axios that the absence of forward guidance under Federal Reserve Chair Kevin Warsh carries "a price to be paid," and Barclays wrote that a worsening fiscal path should keep long yields elevated.

Both crude benchmarks are exchange settlements taken from CNBC rather than the later screen quote; gold and natural gas are screen levels at the equity close. The curve is the part worth holding onto. Two-year yields have barely moved in a week while the thirty-year keeps climbing, and steepening driven entirely by the long end is a message about borrowing, not about growth.

Technicals

Nothing structural broke. All three of the S&P's moving averages sit below the index — the 20-day at 7,600, the 50-day at 7,516, the 200-day at 7,079 — and a half-percent decline does not reach any of them. The close did land at the bottom of the session's range, which usually invites a lower open before it invites buyers. The Nasdaq 100 finished at 29,995.38, four and a half points under 30,000.

Rates are the tighter picture. The 10-year at 4.724% has cleared the 4.703% that capped it for three months, and the range it broke was only ten basis points wide. A close back under 4.65% would undo it; failing that, the next reference is the April high near 4.85%.

Breakouts

Micron (MU) closed at $1,011.75, its first finish above $1,000 since July 23 and comfortably clear of a 50-day average at $961. Seagate (STX) at $994.79 sits well above its own 50-day of $890, and $1,094 from January is what stands between it and a new high.

Breakdowns

Meta (META) lost its last support. At $568.97 the stock is under its 20-day, its 50-day at $595.96 and its 200-day at $626.72, a full stack that took three weeks to break; $525.72 is the 52-week low beneath. Nike (NKE) at $39.09 registered a fresh 52-week low and, per Proactive Investors, its weakest level in eleven years, with no prior support to reference on the chart.

SanDisk hourly: the day's largest advance among liquid names, an 8.88% gain to $1,786.85.

Top Movers

Gainers

SanDisk (SNDK) rose 8.88% to $1,786.85, the largest advance in a group that has been climbing since the middle of last week. Friday, Peter Diamandis posted on X that memory rather than compute limits the pace of artificial intelligence, and Elon Musk replied "Few realize this" — a thin catalyst alone, but it landed on top of Thursday's investor day and its 80% gross-margin target for fiscal 2028 through 2030. RBC lifted its target to $1,600 on Friday and Wells Fargo to $1,550, both keeping neutral ratings, which tells you the stock has outrun the analysts covering it.

Micron (MU) added 4.13% to $1,011.75. New Street upgraded it to Buy at $1,250 on Friday, and Bank of America models fiscal 2030 earnings of $200 to $250 a share against a Street peak of $160 to $170.

Applied Materials (AMAT) gained 5.55% to $535.31 and Western Digital (WDC) 5.35% to $536.01, the equipment and drive ends of the same shortage. Neither has reclaimed its 50-day average, so this is a bounce inside a downtrend.

Losers

Microsoft (MSFT) fell 3.04% to $480.35 on the Guardian report questioning its installed chip base. The stock had run 16% off its June low into today, so the story arrived at an expensive moment. Wells Fargo had raised its target to $700 last Wednesday.

Meta (META) dropped 3.54% to $568.97 on the eve of the Oakland trial. The legal exposure is only part of it: capital spending guidance of $130bn to $145bn has already pushed quarterly free cash flow down to $784 million, and a company defending its product design in court has less room to spend its way out.

Nike (NKE) lost 4.03% to $39.09 after a UBS downgrade built on falling resale prices for Nike and Jordan footwear. The secondary market is where brand heat shows up first, and it has gone cold.

Adobe (ADBE) slid 3.78% to $254.04, still working through Morgan Stanley's underweight call and an open chief executive search.

Micron closed at $1,011.75, its first finish above $1,000 since July 23.

Meta at $568.97 is below its 20-day, 50-day and 200-day averages.

Nike's $39.09 close is a fresh 52-week low.

Key Macro Data Today

Two second-tier releases both came in better than forecast, which did nothing to help the bond market.

Empire State is a regional survey with a deserved reputation for noise, and a beat of nearly ten points handed bond buyers one more reason to stay away. The builder survey is the more useful number: at 35 it marks a sixteenth straight month below 40, and a sixteenth month in which at least 30% of builders cut prices. Rising diesel costs are feeding into materials, which is the oil story arriving in housing.

Notable Earnings This Session

Nothing consequential reported before the open or after the close; the week's substance starts Tuesday morning with Home Depot, followed by Target on Wednesday and Walmart on Thursday at 7:00 ET.

Drivers

1. Home Depot reports at roughly 6:00 ET, the first real look at the consumer since Friday's retail sales figure. The stock goes in at $337.88, under a 200-day average of $347.10, and comparable sales in the big-ticket renovation categories are the line to find. Builder confidence at 35 and mortgage costs where they are, the financing backdrop for that spending has not improved since May.
2. The long end has cleared last month's high and sits 13 basis points under the 5.44% it reached in 2007. Nothing on Tuesday's calendar speaks to it directly; the July Federal Reserve minutes arrive Wednesday afternoon.
3. Micron above $1,000 and SanDisk above $1,700 are levels reached on a social-media exchange and a run of price-target hikes, not on new orders. Whether the memory group extends its climb without fresh news from Asia is Tuesday's question. The next scheduled catalyst is Nvidia's report on August 26.
