Returns Overview

ProAssurance Corporation (PRA) — Return Performance

ProAssurance Corporation delivered a mixed return profile over the past five years, with notable strength in the longer horizon but volatility in shorter periods. While the stock posted an impressive 102.21% total return over two years, it lagged its sector ETF by 66.99% (alpha) and underperformed the broader market by 72.21% on a risk-adjusted basis. Conversely, recent month‑to‑month performance was modestly positive at 3.0%, yet still generated only 1.61% alpha versus the financial services sector.

Period Returns vs S&P 500 & XLF

Monthly Returns Heatmap

PRA

The company produced strong absolute returns in the medium term, especially a 102.21% gain over two years, but its sector‑adjusted alpha was negative across most horizons, indicating underperformance relative to peers. Short‑term results were flat to slightly positive (e.g., -0.04% over three months) with minimal alpha, while long‑term returns (5‑year 10.46%) were heavily dragged down by a -61.35% sector alpha, highlighting a divergence between absolute performance and relative weakness.

Volatility Analysis

ProAssurance Corporation (PRA) — Volatility Profile

ProAssurance Corporation exhibits markedly higher price variability than the broader market, with an annualized volatility of 36.32% compared to the S&P 500's 17.78%, indicating more than double the typical price swings. The stock’s downside profile is severe: a downside deviation of 28.3% and a historic maximum drawdown of -78.83% spanning from December 2017 to July 2024, with no recovery to prior peaks, underscores substantial tail‑risk exposure. While recent short‑term volatility (60‑day at 8.7%) exceeds the longer‑term 252‑day level (6.2%), both remain above the long‑run average implied by the annualized figure, suggesting persistent elevated risk.

Volatility Metrics

PRA

The company’s volatility is more than twice that of the S&P 500, reflecting a highly reactive price pattern likely driven by sector‑specific regulatory and claim‑frequency dynamics. Downside deviation at 28.3% signals that negative returns are both frequent and pronounced, while the -78.83% max drawdown over nearly seven years highlights an extended period of capital erosion without any meaningful bounce‑back, raising concerns about liquidity and investor confidence. The current 60‑day volatility of 8.7% sits above the trailing 252‑day level of 6.2%, indicating that recent market stress or company‑specific events have amplified short‑term risk relative to its longer‑term baseline.

ProAssurance’s annualized volatility is 104% higher than the S&P 500.
Downside deviation of 28.3% points to a pronounced skew toward negative returns.
The -78.83% max drawdown represents an extreme loss event with a multi‑year duration and no recovery.
Short‑term (60‑day) volatility exceeds the longer‑term (252‑day) measure, signaling heightened recent risk.

Positive Characteristics
Despite high overall volatility, the 252‑day volatility of 6.2% is modest relative to the annualized figure, indicating that periods of calm do occur.
The stock’s elevated downside deviation can be useful for investors seeking higher risk premia in a diversified portfolio.

Beta & Correlation

ProAssurance Corporation (PRA) — Beta Profile

ProAssurance Corporation exhibits a trailing beta of 0.689 relative to the S&P 500, placing it firmly in the defensive range (<0.8). This indicates that the stock tends to move less than the broad market during both up‑ and down‑turns, offering a cushion against equity volatility. However, its sector beta of 0.733 versus the Financial Services index (XLF) shows slightly higher sensitivity to sector movements, suggesting that sector dynamics contribute more to the stock’s risk profile than the broader market does.

Beta & Correlation Metrics

PRA

The upside beta of 0.642 versus a downside beta of 0.758 signals an asymmetric risk exposure: the share is less responsive when markets rise but more reactive during declines, a pattern that risk‑averse investors should note for portfolio protection. With an R-squared of 11.4% against the S&P 500, only a modest portion of PRA’s returns are explained by overall market movements, meaning the majority (88.6%) is idiosyncratic and can be diversified away. The sector correlation of 0.439 and sector R² of 19.2% further indicate that while financial‑sector trends matter, they still account for less than one‑fifth of price variation.

Trailing market beta (0.689) classifies PRA as defensive, implying lower volatility than the S&P 500.
Downside beta (0.758) exceeds upside beta (0.642), highlighting greater sensitivity to market declines.
Low overall R-squared (11.4%) suggests that most price movement is driven by company‑specific factors rather than broad market forces.
Systematic risk accounts for only 11.4% of total variance, leaving 88.6% as idiosyncratic – a favorable profile for diversification.
Sector beta (0.733) exceeds the pure market beta, indicating that financial‑sector dynamics are a more material source of risk than general equity trends.

Positive Characteristics
Defensive market beta reduces exposure to broad equity swings, which can be attractive in volatile environments.
High idiosyncratic component (88.6%) offers potential for active stock selection to generate alpha.
Sector correlation below 0.5 suggests that PRA does not move in lockstep with the broader financial services sector.

Positive Notes

Defensive market beta reduces exposure to broad equity swings, which can be attractive in volatile environments.

Risk-Adjusted Returns

ProAssurance Corporation (PRA) — Risk-Adjusted Performance

ProAssurance Corporation (PRA) delivers a modest risk‑adjusted return profile as indicated by its Sharpe ratio of 0.021, which is well below the benchmark threshold of 1.0 and signals that total returns barely exceed the risk‑free rate after accounting for volatility. The Sortino ratio of 0.027 marginally exceeds the Sharpe figure, suggesting that downside volatility is slightly lower than overall volatility, yet both ratios remain near zero, implying limited excess return per unit of risk. Other metrics reinforce a subdued performance: the Calmar ratio of 0.056 points to very low returns relative to the worst historical drawdown, while the negative Information Ratio (‑0.243) indicates that active management has underperformed its benchmark on a risk‑adjusted basis.

Risk-free rate: 3.63% (Fed Funds Rate)

Risk-Adjusted Metrics

PRA

The Sharpe and Sortino ratios for PRA are both close to zero, with the Sortino modestly higher, indicating that while downside risk is marginally less pronounced than total volatility, the overall excess return over the risk‑free rate remains negligible. The Calmar ratio of 0.056 underscores a weak return-to-drawdown relationship; even small drawdowns erode a large portion of the already limited upside. Moreover, an Information Ratio of ‑0.243 reveals that any active positioning has not generated consistent alpha, and the Treynor ratio of 1.11, though positive, must be interpreted cautiously because it reflects return per unit of systematic risk without compensating for the poor absolute performance captured by the other metrics.

Sharpe ratio (0.021) is far below the 1.0 benchmark, indicating minimal excess return relative to total volatility.
Sortino ratio (0.027) exceeds Sharpe slightly, showing a modestly better downside risk profile but still near zero.
Calmar ratio (0.056) reveals that returns are extremely small compared with the maximum historical drawdown.
Information Ratio (‑0.243) signals underperformance relative to the benchmark on a risk‑adjusted basis.
Treynor ratio (1.11) suggests positive return per unit of systematic risk, yet it does not offset the weak absolute performance.

Positive Characteristics
The Sortino ratio being higher than the Sharpe indicates that downside volatility is slightly less severe than overall volatility.
A positive Treynor ratio shows the stock has generated some return for each unit of market beta exposure.

Positive Notes

The Sortino ratio being higher than the Sharpe indicates that downside volatility is slightly less severe than overall volatility.

A positive Treynor ratio shows the stock has generated some return for each unit of market beta exposure.

Market Regime Analysis

ProAssurance Corporation (PRA) — Regime Behavior

ProAssurance Corporation exhibits a mixed performance profile across market regimes, reflecting its sensitivity to both equity market direction and volatility levels. In bull markets with low volatility, the stock delivers modest gains of 1.27% per month, while in volatile uptrends (bull-highvol) it underperforms, posting an average monthly decline of -0.58%. Conversely, during bear periods the company shows resilience: in orderly declines (bear-lowvol) it generates a strong positive return of 2.81% per month, yet in turbulent down markets (bear-highvol) it again turns negative at -0.69%. The overall capture ratio of 2.11—driven by an upside capture of 21.1% and a downside capture of only 10.0%—indicates that the stock tends to preserve capital during market drops while participating modestly in rallies, a hallmark of defensive equities.

Current Market Regime: Bull-HighVol

Bull-LowVol = calm uptrend • Bull-HighVol = volatile uptrend • Bear-LowVol = orderly decline • Bear-HighVol = crisis

Regime Returns & Capture Ratios

PRA

In the current bull-highvol regime, ProAssurance is expected to face headwinds, as historical data shows a -0.58% average monthly return during similar periods, suggesting that heightened market volatility erodes its upside potential. However, its defensive characteristics become evident in bear environments; the 2.81% gain in bear-lowvol and limited loss of -0.69% in bear-highvol demonstrate an ability to generate positive returns or limit downside when equity markets are falling. The high capture ratio (2.11) reinforces this defensive tilt, as the stock captures twice as much upside relative to its downside exposure.

Investment Highlights & Risk Summary

ProAssurance Corporation (PRA) — Summary & Implications

ProAssurance Corporation delivered an 8.23% total return over the past year, yet its performance lagged the broader market by a substantial margin, generating a negative alpha of -10.76% versus the S&P 500 and underperforming its sector benchmark (XLF) by 7.68% on a risk‑adjusted basis. The stock’s volatility is elevated at an annualized 36.32%, and it experienced a historic max drawdown of -78.83%, flagging severe capital loss risk that dominates the risk profile. On the upside, the company captured only 21.1% of market gains while limiting downside exposure to 10.0%, reflecting a modest capture ratio but insufficient upside participation for growth‑oriented investors. Overall, the combination of high volatility, deep drawdown history, and weak risk‑adjusted returns suggests that PRA is best suited for investors with a high tolerance for loss who seek sector‑specific exposure rather than as a core holding in a balanced portfolio.

Summary Dashboard

Investment Highlights

Sector beta of 0.733 indicates the stock moves less than the financial services index, offering some defensive characteristics during market swings.
Downside capture of only 10.0% suggests limited loss relative to the S&P 500 in down markets, providing a modest hedge against broader equity declines.
The company’s upside capture of 21.1% demonstrates that it participates in market rallies, albeit at a lower magnitude than peers.
Annualized volatility of 36.32% is higher than the S&P 500's 17.1%, reflecting a risk premium that could appeal to investors seeking higher potential return for bearing additional risk.

Risk-Return Rankings

PRA HIGH

High volatility and a historic -78.8% drawdown outweigh modest upside capture, resulting in an unfavorable risk‑return profile.

Strength: Low downside capture (10.0%) limiting losses relative to the market

Concern: Deep historical drawdown of -78.83% indicating severe capital loss potential

Key Takeaways

Negative alpha (-10.76%) versus the S&P 500 signals underperformance on a risk‑adjusted basis.
Sharpe ratio of 0.021 and Sortino of 0.027 are far below the benchmark of 1.0, indicating poor excess return per unit of risk.
The stock’s beta of 0.689 suggests lower sensitivity to market movements but does not offset the impact of extreme drawdowns.
Upside capture is weak (21.1%), limiting participation in market rallies and reducing upside potential.

PORTFOLIO IMPLICATIONS

Given its high volatility, deep drawdown history, and subpar risk‑adjusted returns, ProAssurance should be allocated sparingly within a portfolio, preferably as a small satellite position for investors seeking specific exposure to niche financial services segments. Its low downside capture can provide modest protection during market declines, but the severe historical loss potential means it is unsuitable as a core holding or for risk‑averse investors. Pairing PRA with lower‑volatility, higher‑Sharpe assets could help balance overall portfolio risk while preserving some sector diversification.
