The S&P 500 is commonly split into “growth” and “value” using style indexes (most often the S&P 500 Growth and S&P 500 Value indexes). The exact percentage in each bucket isn’t fixed—those weights move as prices change and as companies’ fundamentals shift. In many recent periods, growth has represented a larger share of the S&P 500 than value, largely because mega-cap growth-leaning sectors (like information technology and certain consumer discretionary names) have carried substantial index weight.
Because the S&P 500 is market-cap weighted, a relatively small number of very large companies can swing the growth-versus-value balance. That means the split can change quickly during rallies or pullbacks concentrated in a handful of high-weight stocks.

Not every provider defines “growth” and “value” the same way. S&P’s methodology uses multiple factors (such as sales growth, earnings changes, and valuation ratios) and can assign a company partially to both styles rather than forcing a 100% growth or 100% value label. Other index providers may use different factors or thresholds, which can lead to different reported percentages.
A higher growth percentage doesn’t automatically mean growth is “better” or “safer”—it simply reflects how the index is currently positioned based on market values and style classification. Investors often use the split to understand portfolio tilt, diversify exposure, or compare performance across market cycles.
For S&P 500 Growth vs Value: Current Split Explained, the best answer depends on fit, material, care instructions, and how the product will be used day to day.
They can change daily as prices move, and they also shift when index providers update style classifications based on new fundamentals. Major moves often happen when a few large companies re-rate higher or lower.
