Diversification was adopted, or borrowed from the Insurance industry, from which it forms the underpinning of underwriting risk

It was incorporated into the financial markets, as it had worked very successfully, over a long period of time, and a large number of individual cases, providing a statistically significant result, with a high confidence level to the results.


There are however some important differences.

If underwriting life insurance, the statistical body of evidence gathered over many years, added to medical statistics regarding mortality rates, due to age, accidents, disease, etc. provided Actuaries with hard data, that changes very little over time.


In the stock market, we have to utlize diversification within two separate classes of risk. alpha risk, and beta risk

Which due to the competitive and secretive nature of the markets makes the aquisition of hard data quite challenging.


alpha risk, is the risk that is better described as business risk that will incorporate the following risks;

Peril,

Physical hazard

Moral hazard

Static risk

Dynamic risk,

Fundamental risks

Particular risks,

Speculative risk

Pure risk,

Liability risks

Failure risk,

Act of God.


beta risk, is Market risk, and most easily observed as "Price movement".

The beta assigned to individual stocks reflects their past volatility, as compared to the benchmark index, of which they are a member.


Both stoplosses, and diversification can be utilized in tandem, or individually, or of course, not at all. There are situations, according to the type of risk, or the amount (risk exposure) that one may be preferrable to the other.
