Risk Analytics & VaR
Nydar's risk analytics calculate Value at Risk using 3 methods — parametric, historical simulation, and Monte Carlo with 10,000 simulated price paths — at the 95% and 99% confidence levels. Nydar stress tests portfolios against the 2008 financial crisis (-56.8%), the March 2020 COVID crash (-33.9% in 23 days), and the May 2021 crypto correction (-53.4%), then measures risk-adjusted performance with Sharpe, Sortino, and Calmar ratios. The VaR framework follows Philippe Jorion's Value at Risk (McGraw-Hill, 3rd ed.).
How Nydar Calculates Portfolio Risk
Nydar uses the same VaR framework described in Philippe Jorion’s Value at Risk (McGraw-Hill, 3rd ed.) and stress testing methodology used by institutional desks

- Nydar computes Sharpe, Sortino, and Calmar ratios
Why Risk Analytics Matter
Protect Your Capital
Nydar calculates your maximum potential loss before it happens. VaR at the 95% confidence level means there is only a 5% chance of losing more than the stated amount in a single day. The framework follows Philippe Jorion’s Value at Risk (McGraw-Hill, 3rd ed.), the standard reference for portfolio risk measurement.
Optimise Position Sizing
Nydar’s correlation matrix shows pairwise relationships between all positions. A portfolio with 5 holdings all above 0.85 correlation has effectively 1 position. Nydar flags concentration risk so traders size positions based on true diversification, not asset count.
Survive Black Swans
Nydar stress tests portfolios against 3 real crash scenarios: the 2008 financial crisis (-56.8%), the COVID crash (-33.9% in 23 days), and the May 2021 crypto correction (-53.4%). Each scenario shows the estimated dollar impact on current positions.
Manual Risk Tracking vs. Nydar
Most traders track P&L but not actual risk. Nydar calculates the metrics institutional desks use to manage exposure.
| Task | The Manual Way | With Nydar |
|---|---|---|
| Measuring max loss | Guessing based on gut feel or ignoring it entirely | Nydar calculates VaR using 3 methods (parametric, historical, Monte Carlo with 10,000 paths) at 95% and 99% confidence levels |
| Crash preparedness | Hoping it does not happen and finding out when it does | Nydar stress tests against 2008 (-56.8%), COVID (-33.9%), and crypto crash (-53.4%) scenarios with dollar impact on current positions |
| Risk-adjusted returns | Looking at total P&L without accounting for risk taken | Nydar computes Sharpe ratio (return/risk), Sortino (downside only), and Calmar (return/drawdown) for the full risk-adjusted picture |
| Diversification check | Assuming 5 positions means diversified | Nydar shows pairwise correlation for all holdings — 5 positions at 0.85+ correlation is effectively 1 position |
| Drawdown tracking | Spreadsheet math or no tracking at all | Nydar tracks maximum drawdown, current depth from peak, and recovery time in days with historical chart overlay |
Complete Risk Toolkit
Nydar provides the same risk analytics used by institutional desks — VaR, stress testing, performance ratios, and correlation analysis — across crypto, stocks, and forex
Value at Risk (VaR)
Nydar calculates VaR using 3 methods — parametric, historical simulation, and Monte Carlo (10,000 paths) — at the 95% and 99% confidence levels over 1-day and 5-day horizons
- Parametric VaR assuming normal returns
- Historical simulation using actual return distribution
- Monte Carlo VaR with 10,000 simulated price paths
- 1-day and 5-day time horizons
- 95% and 99% confidence intervals
Stress Testing
Nydar replays 3 historical crash scenarios against the current portfolio: 2008 financial crisis (-56.8%), March 2020 COVID crash (-33.9% in 23 days), and the May 2021 crypto correction (-53.4%)
- 2008 financial crisis scenario (-56.8% S&P 500)
- COVID-19 crash scenario (-33.9% in 23 trading days)
- May 2021 crypto correction (-53.4% in 6 weeks)
- Custom scenario builder with configurable drawdowns
- Dollar-impact estimate on current positions
Performance Ratios
Nydar calculates Sharpe ratio (excess return per unit of total risk), Sortino ratio (downside risk only), and Calmar ratio (return vs max drawdown) for a complete risk-adjusted picture
- Sharpe ratio — excess return / total volatility
- Sortino ratio — excess return / downside deviation
- Calmar ratio — annualised return / max drawdown
- Risk-free rate configurable
- Rolling and cumulative calculations
Drawdown Analysis
Nydar tracks maximum drawdown, current drawdown depth, and recovery time so traders see exactly how far the portfolio has fallen from its peak and how long recoveries take
- Maximum drawdown (peak-to-trough)
- Current drawdown from high-water mark
- Recovery time in days
- Drawdown duration tracking
- Historical drawdown chart overlay
Monte Carlo Simulation
Nydar runs 10,000 simulated price paths using historical volatility and correlation structure to project the full distribution of portfolio outcomes, not just a single point estimate
- 10,000 simulation paths per run
- Probability distributions at configurable horizons
- Best/worst case scenario bounds
- 95% and 99% confidence intervals
- Captures fat-tail risk parametric models miss
Correlation Matrix
Nydar displays pairwise correlation between all portfolio positions — a portfolio with 5 positions all above 0.85 correlation has effectively 1 position in terms of diversification
- Pairwise correlation for all holdings
- Concentration risk identification
- Cross-asset correlation (crypto, stocks, forex)
- Rolling correlation windows
- Diversification score
What the Numbers Mean
Every metric in Nydar’s risk analytics has a specific definition and threshold. Here is what each number tells you.
Value at Risk (VaR)
Nydar calculates VaR using 3 methods. Parametric VaR assumes normal returns — fast but misses fat tails. Historical VaR uses actual return distributions, capturing the real shape of crypto and stock returns. Monte Carlo VaR runs 10,000 simulated paths using historical volatility and correlation. For a $100,000 portfolio with 15% annualised volatility, the 1-day 95% VaR is approximately $2,470. Framework: Jorion, Value at Risk (McGraw-Hill, 3rd ed.).
Performance Ratios
Nydar computes 3 ratios. Sharpe = excess return / total volatility (above 1.0 is good, above 2.0 is excellent). Sortino = excess return / downside deviation only (ignores upside volatility, so a better measure when returns are skewed). Calmar = annualised return / max drawdown (penalises large peak-to-trough drops). Together, these 3 ratios give a more complete risk-adjusted picture than any single metric.
Sharpe ratio originated with William Sharpe (1966). Sortino ratio refines it by measuring only downside risk.
Stress Testing
Nydar replays historical crash scenarios against current positions. The 2008 financial crisis produced a -56.8% S&P 500 peak-to-trough drop. The March 2020 COVID crash hit -33.9% in just 23 trading days. The May 2021 crypto correction saw Bitcoin fall -53.4% in 6 weeks. Each scenario shows the estimated dollar impact on the trader’s current positions.
Traders can also build custom scenarios with configurable drawdown assumptions.
Correlation Matrix
Nydar displays pairwise correlation between all portfolio positions. Correlation ranges from -1.0 (perfect inverse) to +1.0 (perfect positive). A portfolio with 5 positions all above 0.85 correlation has effectively 1 position in terms of diversification. Nydar flags high-correlation clusters and computes cross-asset relationships across crypto, stocks, and forex to identify true diversification.
Markowitz's Modern Portfolio Theory (1952) demonstrated that diversification reduces risk only when asset correlations are below 1.0.
