The macro backdrop

Every theme swims in this tide — judge the week’s moves against it.

📅 On the calendar — and why it matters here

• Fri Sep 11 — CPI (inflation). a hot print pushes rate-cut odds out (pressuring long-duration assets); a soft print does the reverse — one of the highest-impact releases. Watch for a surprise vs expectations — that gap, not the number itself, is what moves markets.
• Fri Sep 11 — FOMC (Fed rate decision / minutes). the single biggest scheduled market mover — a rate surprise in either direction repriced everything, hardest on rate-sensitive names (growth, REITs, utilities, homebuilders). Watch for a surprise vs expectations — that gap, not the number itself, is what moves markets.
• Wed Sep 16 — Retail sales. the consumer's pulse — matters most to consumer/retail names. Watch for a surprise vs expectations — that gap, not the number itself, is what moves markets.

What to watch next

• The median price-to-model-value for 14 stocks in this theme is 1.56x. This metric provides a valuation context for the sector, where a higher multiple could suggest that stocks are trading above their intrinsic value based on a model, or that growth expectations are elevated (src: ["own"]). [SAVNG data]
• The VIX, a measure of market volatility, is at 15.74. A VIX reading in this range generally indicates moderate market expectations for volatility, which can influence investor sentiment and the perceived risk of growth-oriented sectors like social media (src: ["macro"]). [macro data]
• The Shiller CAPE ratio is at 40.73, and market risk is assessed at 51/100. These macro indicators suggest a broader market environment that may be characterized by higher valuations and moderate overall market risk, which can affect how investors perceive and value social media stocks (src: ["macro"]).
