• Stochastic modeling predicts the likelihood of different outcomes under different conditions using random variables.

  • Stochastic modeling represents data and predicts outcomes given certain levels of unpredictability or randomness.
  • In the financial services sector, planners, analysts and portfolio managers use stochastic modeling to manage their assets and liabilities and optimize their portfolios.
  • The opposite of stochastic modeling is deterministic modeling, which gives the same exact results every time for a certain set of input data.
  • Monte Carlo simulation is one example of a stochastic model; it can model the behavior of a portfolio based on the probability distribution of returns on individual stocks.
