Suite of quantitative tools covers portfolio modeling and backtesting, Monte Carlo simulations, portfolio optimization, factor models, and tactical asset allocation models.
Try the Monte Carlo simulation to see how a portfolio may perform over the short or long term:
For example, you can combine 90% SPY (S&P 500 ETF) with 10% BIL (Treasury Bills) and see how it performs compared to just the S&P 500. Or use a total stock market fund like VTI instead.
Compare the 10th percentile to the 50th to see how risky a strategy can be.
