Returns Overview

Nano Nuclear Energy Inc (NNE) — Return Performance

Nano Nuclear Energy Inc (NNE) displayed a highly volatile return profile over the past year, posting a cumulative loss of 31.69% while underperforming its industrial sector ETF by 50.66 percentage points. The short‑term picture is mixed: a sharp 18.42% decline in the last month was offset by a 15.04% gain over three months, yet both periods still lagged sector alpha, delivering -15.83% and +1.94% versus the benchmark respectively.

Period Returns vs S&P 500 & XLI

Monthly Returns Heatmap

NNE

The one‑month return of -18.42% generated a negative alpha of -15.83%, indicating the stock fell far more than its sector peers. Over three months, the 15.04% gain produced a modest positive alpha of +1.94%, suggesting a brief outperformance that was quickly erased by the subsequent six‑month decline of -1.87% with an alpha of -9.74%. The year‑to‑date loss of -31.69% and a two‑year return of just 0.51% both reflect deep underperformance, with alphas of -50.69% and -34.71% respectively, highlighting persistent downside pressure.

Volatility Analysis

Nano Nuclear Energy Inc (NNE) — Volatility Profile

Nano Nuclear Energy Inc (NNE) exhibits an exceptionally high volatility profile, with an annualized standard deviation of 148.66%, which is roughly 8.3 times the S&P 500's 17.78% benchmark. This elevated dispersion reflects a stock that reacts sharply to market and company‑specific news, generating both large upside spikes and deep downside moves. Downside risk metrics reinforce this picture: a downside deviation of 74.47% and a maximum drawdown of -77.68% over a 36‑day peak‑to‑trough period illustrate the potential for rapid capital erosion, although the subsequent recovery by November suggests resilience under favorable conditions.

Volatility Metrics

NNE

The trailing 60‑day volatility of 106.87% and 252‑day volatility of 98.61% are both materially lower than NNE's long‑term annualized volatility, indicating a temporary easing of price swings in recent months. Despite this short‑term moderation, downside deviation remains high at 74.47%, signaling that even the reduced volatility is skewed toward negative moves. The maximum drawdown of -77.68% unfolded over roughly one month, with a full recovery taking about three and a half months, highlighting both acute risk exposure and the capacity for rebound when market sentiment improves.

NNE's annualized volatility is approximately 8.3x that of the S&P 500, underscoring extreme price fluctuation.
Downside deviation of 74.47% indicates a pronounced bias toward negative returns within volatile periods.
The -77.68% max drawdown occurred over a 36‑day window, demonstrating rapid downside risk concentration.
Recent 60‑day and 252‑day volatilities are below the long‑term average, suggesting temporary volatility compression.

Positive Characteristics
Trailing volatilities (60d/252d) have fallen below the historical norm, offering a short‑term reduction in risk exposure.
The stock recovered from its deepest drawdown within roughly 106 days, showing potential for price rebound after sharp declines.

Beta & Correlation

Nano Nuclear Energy Inc (NNE) — Beta Profile

Nano Nuclear Energy Inc (NNE) exhibits a trailing beta of 2.72 versus the S&P 500, placing it firmly in the aggressive category (>1.2). This indicates that the stock moves roughly 2.7% for every 1% move in the broad market, amplifying both gains and losses. The upside beta (2.124) is lower than the downside beta (2.824), revealing a pronounced asymmetry: NNE tends to decline more sharply on market downturns than it rises on up‑moves, a critical consideration for risk‑averse investors. With an R-squared of 8.8% and a correlation of 0.296, only a small fraction of the stock’s variance is explained by market movements, meaning diversification benefits are substantial because the majority of price action (91.2%) is idiosyncratic. Comparing its market beta (2.72) to sector beta (2.243) against Industrials (XLI) shows that roughly 0.48 beta points stem from broader market exposure while 0.48 points arise from sector‑specific dynamics, highlighting a balanced mix of general and industry risk.

Beta & Correlation Metrics

NNE

The trailing market beta of 2.72 signals that NNE is highly volatile relative to the S&P 500, delivering amplified returns in bullish cycles but also heightened drawdowns when the market falls. The asymmetric downside beta of 2.824 versus upside beta of 2.124 suggests a steeper loss profile during market corrections, implying that risk managers should allocate tighter stop‑losses or hedge more aggressively for this stock.

Trailing beta of 2.72 classifies NNE as an aggressive, high‑beta security.
Downside beta (2.824) exceeds upside beta (2.124), indicating greater sensitivity to market declines.
R-squared of 8.8% means only a small portion of price variance is driven by the broader market.
Idiosyncratic risk accounts for 91.2% of total variance, offering strong diversification potential.
Sector beta (2.243) shows that roughly 48% of NNE's beta stems from Industrials exposure, with the remainder linked to overall market movements.

Positive Characteristics
High idiosyncratic component provides diversification benefits for portfolios seeking non‑correlated returns.
Despite aggressive beta, the lower upside beta suggests some moderation in gains, which can temper extreme volatility spikes during strong bull markets.

Risk-Adjusted Returns

Nano Nuclear Energy Inc (NNE) — Risk-Adjusted Performance

Nano Nuclear Energy Inc (NNE) demonstrates a solid risk-adjusted return profile across multiple metrics. A Sharpe Ratio of 1.172 places the stock above the threshold for good performance, indicating that it delivers excess returns over the risk‑free rate on a per‑unit‑risk basis. The Sortino Ratio of 2.34 exceeds the Sharpe, signaling that downside volatility is markedly lower than overall volatility and that the company’s return distribution is skewed toward upside gains.

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

Risk-Adjusted Metrics

NNE

The Calmar Ratio of 2.289 suggests that NNE has generated roughly 2.3 times its worst historical drawdown, reflecting a relatively moderate loss severity in the context of its total return. An Information Ratio of 1.102 indicates consistent alpha generation above a relevant benchmark, reinforcing the view that active management or company-specific factors have added value.

Calmar Ratio >2 implies the stock’s returns comfortably exceed its maximum drawdown magnitude.
Information Ratio >1 signals robust and consistent alpha generation.

Positive Characteristics
Strong upside potential with limited downside volatility.
Consistent outperformance relative to benchmark as reflected in the Information Ratio.
High return per unit of systematic risk, evidenced by an elevated Treynor Ratio.

Market Regime Analysis

Nano Nuclear Energy Inc (NNE) — Regime Behavior

Nano Nuclear Energy Inc (NNE) demonstrates a pronounced sensitivity to market volatility regimes, delivering robust returns in bullish environments while exhibiting vulnerability during bearish periods marked by heightened turbulence. In Bull-LowVol conditions the stock posted an average 18.56% monthly return over eleven months, reflecting strong upside participation when the broader market enjoys steady gains. The performance moderates to a still respectable 15.2% average in Bull-HighVol settings, indicating that even amid elevated market swings the company can capture significant upside. Conversely, NNE lacks any historical record in orderly bear markets (Bear-LowVol) and suffers a steep decline of -13.66% on average during Bear-HighVol months, underscoring its exposure to downside risk when volatility spikes alongside falling equity prices. The current Bull-HighVol regime suggests that investors can expect continued upside capture, but should remain mindful of the stock’s heightened downside sensitivity if market sentiment turns sharply negative.

Current Market Regime: Bull-HighVol

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

Regime Returns & Capture Ratios

NNE

During bullish phases NNE excels, delivering 18.56% average returns in calm uptrends and 15.2% when volatility is elevated, driven by an upside capture ratio of 723.4%. This means the stock outperforms the S&P 500 by more than sevenfold on the upside. However, its downside capture stands at 495.1%, indicating that during market drops it loses nearly five times as much as the index, which manifested in a -13.66% average loss during Bear-HighVol periods. The absence of performance data in Bear-LowVol regimes further highlights the stock’s lack of defensive characteristics.

Investment Highlights & Risk Summary

Nano Nuclear Energy Inc (NNE) — Summary & Implications

Nano Nuclear Energy Inc (NNE) delivers a strikingly high upside capture of 723.4% and an elevated Sharpe ratio of 1.172, indicating strong excess returns per unit of total risk despite severe volatility. The stock’s Sortino ratio of 2.34 further underscores that its positive returns are generated with relatively less downside deviation, appealing to investors who focus on reward‑to‑downside risk. However, the company exhibits an extreme beta of 2.72 and a downside beta of 2.82, amplifying market movements and exposing investors to amplified losses during market downturns, as reflected by a 77.7% max drawdown and annualized volatility of 148.66%. Over the past year, NNE underperformed both the S&P 500 (alpha –50.69%) and its industrial sector peers (sector alpha –50.66%), suggesting that any upside potential must be weighed against substantial downside risk.

Summary Dashboard

Investment Highlights

Sharpe ratio of 1.172 exceeds the benchmark threshold of 1.0, indicating efficient risk‑adjusted performance.
Sortino ratio of 2.34 signals strong return generation relative to downside volatility, a favorable metric for risk‑averse investors.
Upside capture of 723.4% demonstrates that the stock participates heavily in market rallies, offering significant upside potential when equities rise.
High capture ratio (upside 7.23x vs downside 4.95x) suggests asymmetric return dynamics that can benefit aggressive portfolios.

Risk-Return Rankings

NNE HIGH

Exceptional upside participation and strong risk‑adjusted ratios are offset by extreme volatility, beta, and deep drawdowns.

Strength: Sharpe ratio above 1.0 with a Sortino exceeding 2.0

Concern: Annualized volatility of 148.66% and max drawdown of –77.68%

Key Takeaways

NNE offers compelling upside capture but at the cost of amplified market exposure.
The high beta (2.72) and downside beta (2.82) mean losses can exceed market declines significantly.
Despite strong Sharpe and Sortino metrics, the stock’s recent performance lagged both the S&P 500 and its sector by over 50%.
Investors should be prepared for large price swings; the risk‑reward profile suits speculative or high‑conviction allocations rather than core holdings.

PORTFOLIO IMPLICATIONS

Given its elevated volatility and asymmetric beta, NNE is best positioned as a satellite holding within a diversified portfolio, complementing lower‑beta, stable assets to enhance overall upside capture while managing total portfolio risk. Allocation should be limited to a modest percentage of capital, with strict stop‑loss controls to mitigate the potential for severe drawdowns during market stress.
