Which index should I follow to understand how the investment markets are doing?

For most purposes, the single best “how are markets doing?” gauge is the S&P 500 for U.S. stocks, paired with one broad global stock index and one broad bond index if you want a fuller picture.

Core index to watch

• S&P 500 (U.S. large‑cap stocks): Tracks about 500 of the largest U.S. companies and is the standard benchmark for the U.S. equity market.
• Why it works: Broad, diversified, market‑cap weighted, and used by most professionals as the primary reference point for “the market.”

Other useful equity indices

• Dow Jones Industrial Average: Only 30 big U.S. companies, price‑weighted, more of a media headline barometer than a true market proxy.
• Nasdaq Composite: All stocks listed on Nasdaq, heavily tilted to tech and growth; good for sensing risk appetite in growth/tech but not the whole market.
• Major non‑U.S. indices: Examples include the UK FTSE 100, Germany’s DAX, Japan’s Nikkei 225, and broader baskets like STOXX Europe 50 for regional views.​

A simple equity “dashboard”

• U.S. broad market: S&P 500.
• Global flavor: A broad “world” index (e.g., MSCI ACWI or FTSE All‑World, usually visible on major finance sites as a “World” or “Global” index proxy).

Fixed income and risk tone

If you care about overall risk conditions, add one big bond index:

• Bloomberg Global Aggregate Bond Index (“Global Agg”): Widely used benchmark for global investment‑grade bonds (government and high‑grade corporate).​
• FTSE World Government Bond Index (WGBI): Focuses specifically on developed‑market government bonds and is a leading sovereign bond benchmark.​
• S&P Aggregate Bond indices: Provide regional and global bond snapshots similar in spirit to the Global Agg.​

For a concise daily sense of “how markets are doing,” you could:

• Check S&P 500 for U.S. equities.
• Glance at one global equity index (e.g., “World” or “Global” index on a quote page).
• Look at a broad bond index level/change (Global Agg or a U.S. Aggregate index) to see how rates/fixed income are behaving.
