What it measures

The S&P 500 net income growth rate measures the year-over-year percentage change in aggregate trailing-twelve-month net income for index constituents. A reading of +8% means the index's aggregate after-tax profit grew 8% versus the equivalent twelve-month window one year earlier.

Why it matters

Net income growth, unlike EPS growth, is not affected by share count changes from repurchases or dilution — it measures organic earnings expansion in absolute dollar terms. It is the direct driver of book value accumulation and the primary input to intrinsic value. When net income growth lags EPS growth persistently, it signals that buybacks are doing the work, which is sustainable only as long as buyback funding persists. At the index level, net income growth is the clearest measure of whether the earnings cycle is genuinely accelerating or decelerating.

How it is calculated

NI Growth (YoY, TTM) = (Σ TTM Net Income_t − Σ TTM Net Income_t−4Q) ÷ |Σ TTM Net Income_t−4Q| × 100

LENSE computes the S&P 500 net income growth rate as the year-over-year change in aggregate TTM net income — the sum across current index constituents — not an average of individual company growth rates. TTM net income is constructed by summing the four most recently reported fiscal quarters per constituent using as-reported figures. The prior-year period is the same TTM window offset by four quarters. Periods where the prior-period aggregate net income is zero or negative are excluded. Index constituency is resolved point-in-time via point-in-time index constituency.
