// WEEKLY SNAPSHOT · 2026-06-10 → 2026-06-16 (5 trading days)
A strong week — Market and semis carried it, but stock-picking gave back some of the gains.
The book added about +5.2% this week. Our factor tilts actually pointed higher, predicting +8.8% — being long the market and semiconductors added the most — but name-specific losses trimmed roughly 3.6% against a backdrop of the SpaceX IPO and easing US-Iran tensions. Bottom line: the factor bets worked; stock-picking, not positioning, capped the upside.

What each factor added this week
exactThe book added about +5.2% this week. Market (MKT) contributed +5.1% and Semiconductors (SEMI) +4.9%; Size & Liquidity (SIZE_LIQ) detracted -1.7% and stock-picking took off -3.6%.
What our tilts predicted vs what happened
exactOur factor tilts predicted +8.8%; the book actually returned +5.2%. The -3.6% gap was stock-picking — about 29% of the move came from name-specific moves, not factor bets.
Space sleeve over the week
exactAcross 5 trading days the space sleeve registered no measurable contribution; the top sleeve added +2.4%. Despite the SpaceX IPO headlines, none of it showed up in the space names here.
Which factor turned on vs last week
exactVersus last week, Market (MKT) swung +11.8% and Semiconductors (SEMI) +4.9% from roughly flat, and Equity Volatility (VIX) added about 1.4 points more than the prior week. Aerospace & Defense (DEF) barely moved.
How the book moved with volatility
estimateOver the trailing 60 days the book moved slightly opposite volatility (correlation about -0.27) — a short-sample read that may not hold; this week's 5 days were too few to measure.
The defense-vs-semis barbell
exactOver the week the Semiconductors (SEMI) factor returned +6.7% versus Aerospace & Defense (DEF) at +0.2% — the barbell tilted hard to semis, a gap of +6.5%. Growth (GROWTH) was the weakest at -1.3%.
Space names around the SpaceX IPO
estimateNo space-name move around the SpaceX IPO could be measured this week — the read returned no usable observations.
How to read this
- Stock-picking
- Name-specific stock moves the factor model doesn't explain — i.e. selection, not the book's factor tilts.
- Factor contribution
- How much each factor exposure (e.g. Market, Semis) added to or subtracted from the week's return.
- Predicted vs Actual
- What the book's factor tilts implied for the week vs what it actually returned; the gap is stock-picking.
- Estimate (short-sample)
- A co-movement read over only ~5 trading days — directional, not statistically reliable, and may not hold.
