Investment Portfolios

Since investors like to increase their expected wealth and like to avoid risk or uncertainty, it is possible to imagine different combinations of expected gain and risk which are valued equally by an investor. That is, an investor will be willing to assume greater risk, if he achieves greater expected wealth.

The individual investor is now conceptually prepared to select the optimum portfolio from those constituting the efficient set. The optimum portfolio (i.e., the one which maximizes expected utility) is the one at the point of tangency between the efficient frontier and an indifference curve. In images it can be seen that the investor can do no better than choose the portfolio at point A on the efficient frontier, since no other portfolio is on as high an indifference. Another escape is to say that concavity does not necessarily imply that the relationship is quadratic and that other equations can preserve the concavity without ever implying a maximum value from which utility will decline as wealth increases.

The difficulty with these other curves is that efficiency in terms of the mean and variance of a portfolio does not necessarily imply maximization of expected utility. Markowitz has shown, however, that many utility functions can be reasonably approximated by the quadratic.

A different line of criticism has been advanced by Arditti and others. They argue that investors may be interested in characteristics of distributions of rates of return additional to the mean and variance. In particular, they argue that skewness may be of importance. That is, if the rates of return on the portfolios have the same mean and variance, but different skewness, investors may prefer the distribution which is more skewed to the right. One is not excused from reaching tentative conclusions simply because the theoretical development of a field is still rudimentary.

Whether you want to protect yourself from the financial loss that could result from the death of your prize-winning racehorse, or you simply want to make your golden retriever’s veterinary bills more affordable, you may want to look into purchasing some form of pet insurance. For the most part, pet insurance refers to two types of insurance: mortality insurance and health insurance. These two types of pet insurance may be sold as separate components or together.

Pet mortality insurance

Most of us own animals purely for companionship. However, if you own an animal that has financial value to you (a racehorse), is rare (an exotic animal), or is specially trained (a guide dog for the blind), you may want to consider purchasing pet mortality insurance.

Pet mortality insurance is similar to life insurance for humans. You (the owner) would take out a mortality insurance policy in an amount equal to the value of your pet’s life.

(For example, if you purchased an exotic bird for $ 5,000, you would insure the bird for that amount.) When your pet dies, you would collect on the policy.

The cost of pet mortality insurance is usually calculated as a percentage of the value of the animal. So, when you purchase a policy, you’ll need to show documentation (e.g., breeding records) that substantiates the value of your animal.

Pet health insurance

30% no claims, full accidental loss and damage cover, Regal Insurance provides you with that little extra piece of mind from your home insurance.

Having home insurance is vital, but the type of home insurance that you sign up for will vary depending on your needs. What you should do is look to sign up to a company that will tailor make a policy for you; lots of companies only have set home insurance packages that you can sign up to. What this means is that you end up paying more than you need for your home insurance, because you are paying for ‘perks’ that you will never use.

Companies such as Regal Insurance will amend their home insurance package to suit your exact needs. You can get your building covered up to a value of £1,500,000 and your contents up to a value of £500,000.

With Regal, you are covered for most items up to a value of £5,000 although you can insure individual items separately on a policy if they are worth more.

It is all about making the policy work for you, and choosing a policy that is perfect for you and your needs.

There are loads of other benefits to having a high value insurance policy.  Although no one can deny the fact that you have to pay a monthly premium, the peace of mind that this gives you more than makes up for the cost.
