The VIX vs S&P 500 correlation averages approximately -0.73 over long historical periods, but that number understates how regime-dependent the relationship actually is. During acute stress events, the correlation tightens to -0.85 or stronger. During calm bull markets, it loosens considerably. For a
S&P investment grade ratings run from BBB- at the floor to AAA at the top. According to S&P Global Ratings' published definitions, BBB- or higher signals adequate-to-exceptional capacity to meet financial commitments, while anything below enters speculative-grade territory. For investors managing $5
The FTSE 100 vs S&P 500 comparison is not a contest with a clear winner. It is a structural difference in factor exposure that matters for portfolio construction at scale. The S&P 500 gives you US tech-driven growth. The FTSE 100 gives you value, dividends, and commodity-linked earnings. Whether you
RSP and the cap-weighted S&P 500 hold identical constituents. The difference is how much each stock matters. In the cap-weighted version, the five largest companies currently represent a larger share of your return than the bottom 400 combined. RSP gives every stock the same 0.2% starting weight, re
The S&P 500's revenue leaders and its market cap leaders are almost entirely different lists. Walmart generated over $640 billion in fiscal 2024 revenue yet carries a market cap roughly one-sixth the size of Apple, which produced around $380 billion in revenue. That gap is the entire story of how mo
The S&P 500 Sharpe ratio measures how much return the index delivers per unit of volatility, after subtracting the risk-free rate. Over the long run, that figure averages roughly 0.40 to 0.45. It sounds modest, and it is. But it also beats the majority of actively managed funds on a risk-adjusted ba
The S&P 500 vs inflation chart tells a clear story over long horizons: equities win. Robert Shiller's dataset going back to 1871 shows a real annualized return of approximately 6.5–7% per year. But that average conceals decade-long stretches of deeply negative real returns that can permanently impai
The Russell 1000 vs S&P 500 comparison matters far less than most investors assume, and far more than they realize in specific contexts. Both indices track large-cap U.S. equities with a correlation typically above 0.99. The real distinctions show up in construction methodology, expense ratios, tax
The S&P probability of default table maps each credit rating to a historically observed likelihood of default across multiple time horizons, from one year out to fifteen. AAA-rated issuers have maintained near-zero one-year default rates historically, while CCC/C-rated issuers have exceeded 25% in s
The S&P 500 sector weights over time tell a story that most passive investors miss entirely. Energy commanded roughly 28% of the index in 1980. Today it sits below 4%. Information Technology has gone the other direction, rising from approximately 6% in 1990 to over 28% by the early 2020s, according
For most investors, the S&P 500 vs total market debate is nearly academic. The two indices are highly correlated, the performance gap is rarely more than 0.5% annually, and both deliver broad U.S. equity exposure at near-zero cost. But at $5M or $10M in equity holdings, small differences in composit
The S&P 500 divides its 500 constituents into 11 S&P sectors under the Global Industry Classification Standard, a framework jointly developed by S&P Dow Jones Indices and MSCI in 1999. Understanding which sectors you own, at what weights, and how they behave across economic cycles is foundational to
