Usage

Example 1: Efficient Frontier - Monte Carlo Portfolio Optimization

import pandas as pd
from riskoptima import RiskOptima

# Define your current porfolio with your weights and company names
asset_data = [
    {"Asset": "MO",    "Weight": 0.04, "Label": "Altria Group Inc.",       "MarketCap": 110.0e9},
    {"Asset": "NWN",   "Weight": 0.14, "Label": "Northwest Natural Gas",   "MarketCap": 1.8e9},
    {"Asset": "BKH",   "Weight": 0.01, "Label": "Black Hills Corp.",         "MarketCap": 4.5e9},
    {"Asset": "ED",    "Weight": 0.01, "Label": "Con Edison",                "MarketCap": 30.0e9},
    {"Asset": "PEP",   "Weight": 0.09, "Label": "PepsiCo Inc.",              "MarketCap": 255.0e9},
    {"Asset": "NFG",   "Weight": 0.16, "Label": "National Fuel Gas",         "MarketCap": 5.6e9},
    {"Asset": "KO",    "Weight": 0.06, "Label": "Coca-Cola Company",         "MarketCap": 275.0e9},
    {"Asset": "FRT",   "Weight": 0.28, "Label": "Federal Realty Inv. Trust", "MarketCap": 9.8e9},
    {"Asset": "GPC",   "Weight": 0.16, "Label": "Genuine Parts Co.",         "MarketCap": 25.3e9},
    {"Asset": "MSEX",  "Weight": 0.05, "Label": "Middlesex Water Co.",       "MarketCap": 2.4e9}
]
asset_table = pd.DataFrame(asset_data)

capital = 100_000

asset_table['Portfolio'] = asset_table['Weight'] * capital

start_date = '2024-01-01'
end_date = RiskOptima.get_previous_working_day()

RiskOptima.plot_efficient_frontier_monte_carlo(
    asset_table,
    start_date=start_date,
    end_date=end_date,
    risk_free_rate=0.05,
    num_portfolios=10000,
    market_benchmark='SPY',
    set_ticks=False,
    x_pos_table=1.15,    # Position for the weight table on the plot
    y_pos_table=0.52,    # Position for the weight table on the plot
    title=f'Efficient Frontier - Monte Carlo Simulation {start_date} to {end_date}'
)

Example 2: Portfolio Optimization using Mean Variance and Machine Learning

RiskOptima.run_portfolio_optimization_mv_ml(
    asset_table=asset_table,
    training_start_date='2022-01-01',
    training_end_date='2023-11-27',
    model_type='Linear Regression',    
    risk_free_rate=0.05,
    num_portfolios=100000,
    market_benchmark=['SPY'],
    max_volatility=0.15,
    min_weight=0.03,
    max_weight=0.2
)

Example 3: Portfolio Optimization using Probability Analysis

ANALYSIS_START_DATE = RiskOptima.get_previous_year_date(RiskOptima.get_previous_working_day(), 1)
ANALYSIS_END_DATE   = RiskOptima.get_previous_working_day()
BENCHMARK_INDEX     = 'SPY'
RISK_FREE_RATE      = 0.05
NUMBER_OF_WEIGHTS   = 10_000
NUMBER_OF_MC_RUNS   = 1_000

RiskOptima.run_portfolio_probability_analysis(
    asset_table=asset_table,
    analysis_start_date=ANALYSIS_START_DATE,
    analysis_end_date=ANALYSIS_END_DATE,
    benchmark_index=BENCHMARK_INDEX,
    risk_free_rate=RISK_FREE_RATE,
    number_of_portfolio_weights=NUMBER_OF_WEIGHTS,
    trading_days_per_year=RiskOptima.get_trading_days(),
    number_of_monte_carlo_runs=NUMBER_OF_MC_RUNS
)

Example 4: Macaulay Duration

from riskoptima import RiskOptima
cf = RiskOptima.bond_cash_flows_v2(4, 1000, 0.06, 2)  # 2 years, semi-annual, hence 4 periods
md_2 = RiskOptima.macaulay_duration_v3(cf, 0.05, 2)
md_2
