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 price‑derived signals versus fundamental outcomes for Coastal Financial Corporation (CCB) over the period 2017Q1 to 2026Q1 reveals a modest predictive relationship, primarily driven by realized volatility. Among the three examined signals—12‑month momentum, realized volatility, and relative strength—only realized volatility exhibits a statistically notable correlation with margin change (r=0.42, p=0.029, n=27). All other signal–outcome pairs are weak (|r|<0.22) and lack statistical significance, indicating that price dynamics have limited forward‑looking power for revenue growth or ROE changes in this sample. The absence of cross‑company patterns suggests that the observed volatility‑margin link may be idiosyncratic to CCB rather than a broader market effect.
Realized volatility correlates with margin change at r=0.42 (p=0.029) across 27 quarters – the only statistically notable link.
All momentum‑related signals are weak: 12M Momentum vs Revenue Growth r=-0.16 (p=0.426), vs Margin Change r=0.21 (p=0.288).
Relative strength shows no predictive power; highest |r| is 0.111 for margin change (p=0.581).
Limitations: Sample size is limited to 27 observations per signal, reducing statistical power and increasing the risk of spurious findings. Correlations do not imply causation; observed relationships may be driven by external macro‑economic regimes rather than intrinsic price‑fundamental dynamics. The analysis covers a single firm, so any identified patterns cannot be generalized without additional cross‑company evidence.
CCB
For Coastal Financial Corporation, realized volatility is the only price signal with a notable predictive edge, correlating positively with quarterly margin change (r=0.42, p=0.029, n=27). This relationship can be interpreted as heightened price swings reflecting underlying uncertainty about earnings quality, which later manifests in margin adjustments when management responds to cost pressures or pricing opportunities. By contrast, 12‑month momentum shows negligible association with revenue growth (r=-0.16) and ROE change (r=0.015), suggesting that past price trends are not systematically incorporating upcoming earnings acceleration or profitability shifts for this bank. Relative strength likewise fails to predict any of the fundamentals, underscoring the limited informational content of these technical measures in a financial services context.
