How to read this section: We test whether three price-based signals —
12-month momentum (trailing stock return), realized volatility (annualized standard deviation of daily returns), and
relative strength (stock return minus S&P 500 return) — predict next-quarter fundamental outcomes:
revenue growth, operating margin change, and ROE change (all year-over-year to remove seasonality).
Each cell shows the Pearson correlation (r) between signal at quarter Q and outcome at quarter Q+1.
Values closer to +1 or −1 indicate stronger predictive relationships. “n” is the number of quarterly observations.
The analysis of Edgewell Personal Care Company (EPC) over the 46‑quarter sample from 2015Q1 to 2026Q2 reveals that among the three price‑based signals examined—12‑month momentum, realized volatility, and relative strength—only the 12‑month momentum exhibits a statistically notable relationship with a fundamental outcome. Specifically, 12‑month momentum correlates positively with revenue growth (r=0.472, p=0.002, n=41), meeting the threshold for a notable signal (|r|≥0.4). All other signal–outcome pairings fall below conventional significance levels and display weak or negligible correlations, suggesting limited predictive power in this sample. The absence of cross‑company patterns reinforces that EPC’s price dynamics do not consistently translate into margin or return‑on‑equity changes, nor do volatility or relative strength provide reliable forward‑looking insight for the firm.
12‑month momentum predicts revenue growth for EPC (r=0.472, p=0.002, n=41) – a notable correlation.
Momentum shows no significant relationship with margin change (r=0.062) or ROE change (r=-0.122).
Realized volatility and relative strength have weak correlations with all three fundamentals (|r|≤0.305), none reaching statistical significance.
Limitations: The sample size is limited to 41 observations for each correlation, reducing statistical power. Correlations do not imply causation; observed relationships may be driven by external macro‑economic regimes or coincident events. Signal effectiveness could vary across business cycles, and the analysis does not account for structural changes in EPC’s product mix or market positioning.
EPC
For EPC, the sole predictive signal is the 12‑month momentum indicator, which shows a moderate positive correlation with subsequent revenue growth (r=0.472). This relationship implies that periods of sustained price appreciation over the past year tend to precede higher top‑line expansion, likely because investors incorporate expectations of sales acceleration into the stock price before earnings are reported. In contrast, the same momentum metric exhibits weak and statistically insignificant links to margin change (r=0.062) and ROE change (r=-0.122), indicating that price trends do not capture shifts in profitability or capital efficiency for this business. Realized volatility and relative strength both display low correlations across all fundamentals, with the strongest being a marginal link between realized volatility and ROE change (r=0.285, p=0.071), which does not meet conventional significance criteria.
