Stress Testing Definition

Stress testing refers to a computerized process of testing the ability of investment portfolios or corporations to maintain a level of efficiency in unfavorable future financial situations. Corporations carry out stress testing so as to know how strong they will be and how reliable their investment portfolios will be during extreme financial conditions.

Basically, stress testing helps to determine the reliably of stability of assets and investment portfolios during austere periods. The risks of assets, their efficiency and performs can be evaluated through the stress testing process.

A Little More on What is  Risk Management

Stress testing is an important aspect of risk management for businesses. It entails the use of software of computer simulation to measure the risk of an investment portfolio, especially in future financial conditions. Stress testing does not only help to test the risk of a portfolio, it also helps to devise ways and strategies to mitigate risks and hedge against likely losses.

Portfolio managers conduct stress testing on investment portfolios periodically. This will help them gauge the risks of the portfolio and assess its volatility. Volatility in investment portfolio that are hidden are detected through stress testing.

Regulatory Stress Testing

Types of Stress Testing

There are three major types of stress testing, that are;

  1. Stylized scenarios stress testing,
  2. Hypotheticals  stress testing, and
  3. Historical scenario stress-testing.

In a Stylized scenario stress testing, scientific measures are deployed to check vulnerability in companies as well as ways to maintain efficiency during unfavorable situations.

In a hypothetical stress testing is based on testing on institutions with peculiar crisis manage them. This is more specific, it measures how a firm hedges a crisis.

In a historical scenario stress testing, individual investments and assets are tested using a computer simulation technique based on historical crisis of past events of crisis. Historical crises such as Asian crisis of 1997, the tech bubble of 199-2000 and the 1987 stock market crash can be used.

Aside from the three types of stress testing listed above, there are other stress test methodologies. One of the renowned methodologies is the simulation technique decided by Monte Carlo.
