A macro regime score is a single reading of the market backdrop. It combines several families of economic and market data and sorts the result into a few states, most often risk‑on, neutral and risk‑off. Risk‑on means conditions have tended to reward owning stocks and other risky assets. Risk‑off means conditions have tended to punish them, and investors favour safety.
The word “regime” matters. A regime is a state that lasts, usually for months, not a call on next week’s price. The score answers “what kind of market are we in?”, which is a different question from “where will the S&P 500 be in December?” The basics are in what is a market regime? and the short definition at market regime.
Models differ in what they read. Exent’s regime model reads four pillars: liquidity, credit stress, the economic cycle and sentiment. Other providers use other mixes. A regime score is one input to portfolio protection, alongside how much risk you hold and where the money goes when you step aside.
