W27 — Core PCE 3.4%, yield curve flattens 13bp, GDX −10%

The week ending Friday, June 26, 2026 was busier than the one before it. After a W26 in which all eight of our weekly indicators stayed inside their thresholds, three crossed the line this week: the Nasdaq Composite, the 10-year/2-year Treasury curve, and the U.S. dollar index. None of the three points to systemic stress — credit spreads are still tight and volatility never woke up — but together they sketch a familiar late-cycle picture: stickier inflation at the front end, fading growth expectations at the long end, and a firmer dollar. Underneath the index level, the more interesting story was rotation: almost every winner from the prior week became this week's loser, and vice versa.

① Key Changes Last Week

Three of the eight weekly indicators breached threshold this week, versus zero in W26.

• The 10Y–2Y curve flattened 13bp to +28bp, past the ±10bp weekly threshold. The move was a twist rather than a simple shift: the 2-year yield rose about 6bp to 4.11% while the 10-year fell roughly 7bp to 4.39%. That combination — short rates up, long rates down — is the textbook late-cycle flattening, with the front end pricing stickier near-term inflation and the long end discounting slower growth ahead.

• The dollar index (DXY) climbed 1.4 points to 101.49, past the ±1pt threshold, while the Nasdaq Composite fell 2.55% to 25,359, past the ±2% threshold. A firmer dollar and a tech-led equity pullback often travel together when the market reprices the timing of rate cuts; this week they moved in lockstep.

• May core PCE — the Federal Reserve's preferred inflation gauge — printed at 3.4% year over year (+0.32% month over month) on its June 26 release. That is still well above the Fed's 2% target and was the single most important scheduled data point of the week, arriving on the same Friday that closed out the period.

② 8-Indicator Snapshot

A plain-language read of each weekly indicator, week-over-week against the June 18 close (June 19 was the Juneteenth market holiday, so the prior week's last trade is the comparison point):

S&P 500: 7,357.49 (WoW −0.84%). Within threshold. The broad large-cap index barely moved even as the Nasdaq slid — in plain terms, the damage was concentrated in a slice of the market rather than spread across it.

Nasdaq Composite: 25,358.60 (WoW −2.55%). Breached the ±2% threshold. The tech-heavy index fell more than two-and-a-half percent on the week while the S&P held nearly flat. That gap tells you this was a growth-stock and semiconductor story at the index level, not a market-wide sell-off.

10-Year Treasury yield: 4.39% (WoW −7bp). The long end rallied — remember that bond yields fall when prices rise — as investors leaned toward a slower-growth outlook.

2-Year Treasury yield: 4.11% (WoW +6bp). The front end moved the other way, edging up as the market digested sticky core PCE and trimmed its hopes for near-term rate cuts.

10Y–2Y spread: +28bp (WoW −13bp). Breached the ±10bp threshold. In plain terms, the gap between long-term and short-term interest rates narrowed sharply. A curve that flattens like this — short rates rising into long rates falling — is the bond market's way of saying it expects slower growth even while inflation lingers.

Dollar index (DXY): 101.49 (WoW +1.40pt). Breached the ±1pt threshold, its firmest level in several weeks. A stronger dollar tightens financial conditions at the margin and is a modest headwind for dollar-priced commodities such as gold.

VIX: 18.89 (WoW +0.45). Within threshold — and notably, the volatility index never closed above 20 on any day of the week despite the Nasdaq's decline. The options market simply did not treat this pullback as a scare.

High-yield OAS: 2.78% (278bp, +4bp month-over-month). Within the ±25bp threshold. Corporate credit spreads remain tight, which is the clearest single sign that there is no systemic stress underneath the equity wobble. When trouble is brewing, high-yield spreads usually widen first; they did not.

Net: three of eight breached threshold (Nasdaq, the 10Y–2Y curve, and the dollar); the other five stayed contained.

③ Implications

The cleanest narrative of the week is reversal. The exact assets that led the prior week unwound, and the laggards led. Last week's standout was gold miners (GDX), which had surged about 8.5%; this week GDX gave back 10.3%. Uranium (URA), up roughly 5% the prior week, fell 6.8%. Defense names also unwound, with the Global X Defense Tech ETF (SHLD) down 8.8% and aerospace-and-defense (ITA) off 2.2%. On the other side, leadership rotated back into the cyclical and growth corners: semiconductors (SOXX) gained 4.25%, healthcare (XLV) rose 3.26%, small caps (IWM) added 3.12%, retail (XRT) climbed 3.56%, and industrials (XLI) advanced 2.52%. A single week of mean reversion is not a trend, but it is a useful reminder that the prior week's rush into safe havens and real assets was tactical positioning, not a structural regime change.

What ties it together at the macro level is consistent. Sticky 3.4% core PCE keeps the front end of the curve elevated; a flatter curve and a firmer dollar both nod toward a later stage of the cycle; yet tight high-yield spreads and a sub-20 VIX say the plumbing is calm. That is a "watch, don't react" configuration. The signals worth monitoring from here are whether the front-end repricing and dollar strength persist into next week's labor-market and manufacturing data, and whether the credit market stays as serene as it is now.

We operate on process, not just outcome — and we track and disclose our calls even when they turn out to be wrong.

Position weighting is decided in the monthly debate; this weekly note is for tracking and alerts only, not for changing allocations.

This is not investment advice.

If the flatter curve and stronger dollar are still in place after the June jobs report and the June ISM manufacturing print, that combination becomes a topic worth revisiting in the next monthly debate rather than something to act on within the week.

④ Releases Next Week (W27)

Note on timing: because Independence Day falls on Saturday, July 4, U.S. markets observe the holiday with a full close on Friday, July 3, and an early close on Thursday, July 2. The June employment report is therefore released a day earlier than its usual first-Friday slot.
