February 27, 2026·Historical Reconstruction
This snapshot was built after the fact from historical data, for dates January 2023 through September 2026. It reflects only information that was actually available as of this date - it is not something Persistfolio published at the time.

Current Picture

U.S. equity valuations are unusually high relative to their long-term historical range. Corporate free-cash-flow margins are high, while FCF conversion is unusually low. Capital investment remains unusually high. Financial conditions and inflation are within their typical historical ranges. Real interest rates are within their typical historical range, while the yield curve is positively sloped after the earlier period of inversion. The S&P 500 remains above its 200-day moving average (4.9% above).

Conditions Overview

Market Behaviour

S&P 500 vs 200-day average
The S&P 500's current price compared with its own average price over the last 200 trading days — a common way to describe whether the market is trading above or below its recent trend.
+4.9%

down 3.1 percentage points from previous month

Valuation

CAPE
The S&P 500's price divided by the average of the last 10 years of inflation-adjusted earnings. A long-term valuation measure that smooths out short-term earnings swings.

10.0%

High relative to its historical range · 88th percentile · down 0.3 percentage points from previous month

Rates

Fed policy rate
The federal funds target range set by the Federal Reserve — the rate banks use for overnight lending to each other, and a key reference rate for the broader economy.
3.5%–3.75%

Target range — no historical percentile applies

10Y TIPS real yield
The yield on 10-year Treasury Inflation-Protected Securities — the return investors receive above inflation for lending to the U.S. government over 10 years. Because TIPS principal adjusts for inflation, the yield provides a market-based measure of the real, inflation-adjusted interest rate.
1.72%

Typical relative to its historical range · 68th percentile · down 0.2 percentage points from previous month

10Y–2Y slope
The difference between the 10-year and 2-year Treasury yields. Positive means longer-term rates are higher than shorter-term rates; negative ("inverted") means the opposite.
