Mega-Cap Tech Cracked. The Rest of the Market Climbed

The most crowded corner of the market lost ground all week while the Dow and the small caps finished green. The even-weight strategy caps technology near a sixth of the mix and spreads the rest across six real-economy sectors, so the week the concentrated trade cracked, the build was already sitting on the wide side of it.

TL;DR

• The damage was concentrated. The tech-heavy indexes fell hard while the broad-market gauges rose, as traders re-priced the cost of building out AI and a chip selloff erased ground across the sector. The Nasdaq lost about 4.6%, the Dow gained about 0.6%.

• The other half of the week was calmer. A softer inflation read pulled the ten-year yield below 4.40% for the first time in over a month, crude slid to a three-month low near $70 as the war premium finished unwinding, and the fear gauge pushed up toward 20.

• Both systematic strategies closed the week near fully invested and steady. The even-weight build caps technology near a sixth of the mix with six other real-economy sectors at roughly even weight, the exact construction that sat on the right side of the rotation.

Week in Review

Five sessions, one story. The cost of building out AI moved to the center of the market and the most crowded corner took the hit. Tuesday set the tone, with the Philadelphia semiconductor index falling almost 8% in a single session as investors looked hard at the debt-funded capital spending behind the AI buildout, now topping $450 billion across the largest cloud names for this year alone. The chips bounced Thursday and gave most of it back Friday, with one large semiconductor name off sharply into the weekend.

The split between the indexes was the tell. Money came out of the handful of mega-caps that have run the market for two years and went into almost everything else. The tech-heavy benchmark led the losses while the blue chips and the small caps finished green, a rotation rather than a wholesale risk-off. The calmer side of the week helped. A softer core inflation read for May reduced the odds of multiple rate hikes this year, crude kept sliding back toward pre-war levels as traffic through the Strait of Hormuz started to normalize, and the ten-year yield dropped below 4.40% for the first time in over a month.

For the week (Friday, June 26 close vs. the prior Friday):

• S&P 500: 7,354.02 close, down about 2.0% on the week

• Nasdaq Composite: 25,358.60 close, down about 4.6%, the laggard as the chip names led the selling

• Dow Jones Industrial Average: near 51,880 close, up about 0.6% even as tech fell

• Russell 2000: up about 1.0%, the small caps green while the mega-caps slid

• 10-year Treasury yield: near 4.38%, below 4.40% for the first time in over a month

• 2-year Treasury yield: near 4.09%, the front end easing a few basis points

• VIX: near 20, up on the week as the tech selling picked up

• WTI crude: near $70, a three-month low as the war premium finished unwinding

• Gold: near $4,050, down about 2.6% on the week

• Bitcoin: near $60,200, roughly flat

Allocation Changes

A steady week on both systems, and combined deployment stayed near fully invested with combined cash inside 3.5%.

THOR Index Rotation held all three major benchmarks at roughly a third each, close to 33% apiece, with cash near 1%. The blue-chip index re-entered the rotation the week before and held its place, so the index strategy walked into the selloff spread evenly across all three majors rather than leaning on the growth pair.

THOR Low Volatility kept its seven real-economy sectors at roughly even weight start to finish. Technology stayed the largest near 15.7%, capped at a sixth of the mix, with Industrials at 14.2%, Real Estate at 13.9%, Utilities at 13.8%, Financials at 13.7%, Materials at 13.4%, and Consumer Discretionary at 12.9%. Energy, Healthcare and Consumer Staples stayed at zero. Cash and T-bills held near 2.5%. The even-weight build was already sitting on the wide side of the market the week the concentrated trade cracked, so a quiet week was the construction on the right side of the move.

The Bigger Picture

The week was a referendum on concentration, and it's the one the even-weight build is made for. The indexes that lean hardest on a handful of mega-caps took the damage, with the largest names now near 40% of the cap-weighted benchmark and the chips at the center of the selling. An even-weight strategy caps technology near a sixth of the mix instead of the third-plus it runs in a cap-weighted index, and that cap was the protection the week the AI trade rolled over. The trigger was not the businesses. It was the bill. Aggregate capital spending across the big cloud names tops $450 billion this year, much of it debt-funded, and the market started asking what the return on that looks like.

Where the money sits is the part worth reading. Financials run near 13.7% and remain the cleanest read on the higher-for-longer outcome the Fed confirmed this month. A committee pricing hikes instead of cuts keeps the curve steep, and a steep curve with a working economy is what banks earn on. Industrials sit at 14.2% on real-economy strength. Real Estate near 13.9% and Utilities near 13.8% held even through the rate move, because the demand under them now is the physical layer of the AI build, the data centers and the power that runs them, and a ten-year easing back below 4.40% only helps. The index strategy walks in even across all three majors, so even the technology it owns is one position of three, not the outsized concentration that took the week's losses.

What stayed out says as much as what moved. Energy held at zero through the entire oil round-trip, a barrel that ran past $110 on the war and has now handed all of it back to near $70 as the Hormuz path reopened. The system read the spike as an event, not a confirmed trend, so it never chased the premium and had nothing to give back on the unwind. Healthcare and Consumer Staples, the two corners a nervous market usually crowds into, never cleared the bar even into a tech selloff. The build owns the part of the market that earned its way in and skips the part that hasn't.

THOR Risk Gauge

Both systematic strategies closed the week near fully invested and on the wide side of a market that rotated out of its most crowded corner, with the even-weight build capping technology near a sixth and the index strategy spread evenly across all three major benchmarks. A softer inflation read, the ten-year back below 4.40%, crude at a three-month low and the broad market finishing green while mega-cap tech fell are all constructive for a construction built on real-economy weight rather than concentration. The check is the selling itself. The cost of the AI buildout is back in question and the fear gauge pushed to 20, and the long-duration growth both strategies still own at real weight is the corner taking the damage.

Signal Watch

THOR Index Rotation - As of 6/26/26

All three major benchmarks at roughly a third each, full participation across the indexes. The technology-heavy benchmark is one position of three here, not the concentration a cap-weighted index runs, so the week's mega-cap selling landed on a third of the exposure rather than the whole of it.

THOR Low Volatility - As of 6/26/26

Seven real-economy sectors at roughly even weight, technology capped near a sixth of the mix rather than the third-plus it runs in a cap-weighted index, which is the line that did the work the week the chip names sold off. Financials and the rate-sensitive sectors stayed on as the curve kept its steepness and yields eased. The three out, Energy, Healthcare and Consumer Staples, are the supply-driven and classic-defensive corners the system hasn't confirmed.

THOR AdaptiveRisk Dynamic - As of 6/26/26

The actively managed strategy runs roughly 58% equity, 23% commodity, 11% specialty and currency, and 8% fixed income. A gold-strategy position anchors the commodity side, a short-yen position carries the macro view, and a dedicated rate hedge sits against the higher-for-longer backdrop the week reinforced.

10-year Treasury yield falls below 4.5% as oil falls to pre-war levels - CNBC, June 24. The calmer half of the week.
