Crypto Portfolio Risk Analyzer

A simple JavaScript library to analyze and assess the risk of cryptocurrency portfolios. It provides important risk metrics including:

- Volatility
- Sharpe Ratio
- Value at Risk (VaR)
- Conditional Value at Risk (CVaR)
- Max Drawdown
- Sortino Ratio

---

Features

- Risk Analysis: Quickly analyze the risk metrics of your crypto portfolio.
- Easy Integration: Install with npm or yarn and use it directly in your JavaScript projects.
- Modular Design: Functions are neatly organized into different modules for better maintainability and extensibility.

---

Installation

You can install the crypto-portfolio-risk-analyzer library via npm or yarn:

$3

``bash
npm install crypto-portfolio-risk-analyzer
`

$3

`bash
yarn add crypto-portfolio-risk-analyzer
`

---

Usage

After installation, you can use the library to analyze your crypto portfolio by passing a list of assets, including the coin ID and other parameters.

$3

`javascript
const { analyzePortfolio } = require('crypto-portfolio-risk-analyzer');

// Define your portfolio (coinId, allocation, etc.)
const portfolio = [
{ coinId: 'bitcoin', allocation: 50, days: 10, varConfidence: 0.99 },
{ coinId: 'ethereum', allocation: 30, days: 10, cvarConfidence: 0.80 },
{ coinId: 'litecoin', allocation: 20, days: 10 }
];

// Analyze the portfolio
analyzePortfolio(portfolio)
.then(result => {
if (result.success) {
console.log('Portfolio Analysis:', result.data);
} else {
console.log('Failed to analyze portfolio');
}
})
.catch(error => {
console.error('Error:', error);
});
`

$3

`json
{
"success": true,
"data": [
{
"asset": "bitcoin",
"volatility": "2.35%",
"sharpeRatio": "1.32",
"allocation": "50%",
"var95": "3.12%",
"cvar95": "4.25%",
"maxDrawdown": "12.54%",
"sortinoRatio": "1.67",
"riskSummary": "Risk Analysis for BITCOIN....."
},
]
}
`

Functions

analyzePortfolio(portfolio)

This function performs the risk analysis for each asset in your portfolio.

$3

- portfolio (Array): An array of portfolio objects, where each object contains:
- coinId (String): The coin’s ID (e.g., 'bitcoin', 'ethereum').
- allocation (Number): The percentage of the total portfolio allocated to this coin.
- days (Number, optional): The number of days to fetch historical data for risk calculations (default is 30).
- varConfidence (Number, optional): The confidence level for Value at Risk (default is 0.95).
- cvarConfidence (Number, optional): The confidence level for Conditional VaR (default is 0.95).

$3

- A Promise that resolves to an object with a success field and data field containing the risk analysis results.

Explain Risk Metrics

- Volatility measures how much an asset's price fluctuates over a given period. It is calculated as the standard deviation of daily returns.
- Sharpe Ratio measures the risk-adjusted return of an asset. It is calculated as the ratio of the asset's excess return over the risk-free rate to its volatility.
- Value at Risk (VaR) estimates the maximum potential loss of an asset at a given confidence level over a specified time horizon.
- Conditional Value at Risk (CVaR) estimates the expected loss of an asset beyond the VaR at a given confidence level.
- Max Drawdown measures the maximum loss from a peak to a trough of an asset's value.
- Sortino Ratio` measures the risk-adjusted return of an asset using downside risk (volatility of negative returns) instead of total volatility.
