An "asset-backed security" is used as an umbrella term for a type of security backed by a pool of assets—including collateralized debt obligations and mortgage-backed securities Example: An empirical analysis" PDF.
Hedgeable risks include equity risk, Derivatives paper rate risk, currency risk, credit risk, volatility risk, and commodity risk.
The simplest example of this is buying a put option on a stock. When the stock performs badly, the put performs well and the overall portfolio does not do as badly as it would have done had it not been hedged.
The net effect is dampened returns up or down. As such, companies and funds will try to identify the risk factors to which the portfolio is exposed and hedge against those. This is done by using quantitative risk models which look at the sensitivity Derivatives paper a portfolio to market changes.
If those sensitivities are well understood it may be possible to buy derivatives to reduce the sensitivity of the portfolio. That having been said, one must remember two things. Secondly, this assumes that quantitative models are capable of accurately measuring the risks a portfolio is exposed to.
The risk that the models are incorrect or incomplete is called model risk.
Model risk can arise from uncertainty, time uncertainty, correlation uncertainty, market illiquidity, complexity and poor assumptions like in the models used to price Collateralized Debt Obligations.
As you can see, hedging is certainly no silver bullet. In addition to the concerns I mentioned above there are a number of additional "real world" concerns.
One example is the general cost and complexity of hedging programmes in general hedging can be very expensive.
Back to the top Conclusion Stochastic processes are useful for describing the random processes we find in the world around us. They are used in engineering, genetics, physics, and in quantitative finance. Quants use stochastic processes to project possible returns in markets and changes in interest rates over time.
Stochastic processes are often used in conjunction with Monte Carlo methods to derive fair values for over the counter derivatives. Many stochastic processes exist which operate under different assumptions. Arguably the biggest challenge with stochastic processes is their calibration.
In the future I will write a follow up article about the different calibration techniques available to quants. If you have any questions or corrections please contact me. Identifying these factors and their resulting edges is how investors are able to beat the market.
Once a hypothesis has been formed quantitative investors test it using statistical techniques. Had we invested for 52 weeks after each drop our average return would have been In terms of quantitative asset allocation this means that following a 3.

Our mission is to promote sustained non-inflationary economic growth, and a sound and progressive financial centre.
The paper finds, among other things, that while most funds use no or no substantial amount of derivatives, certain funds do use derivatives extensively.
Certain funds that make greater use of derivatives have received a disproportionately large share of fund inflows since the end of Finance is one of the fastest growing areas in the modern banking and corporate world.
This, together with the sophistication of modern financial products, provides a rapidly growing impetus for new mathematical models and modern mathematical methods.
