Deviant Behavior and Beta

As promised from last week, now it's time to analyze risk and put some numbers to risk.

We've already discovered the difference between market risk and diversifiable risk, so how do we eliminate risk and what kind of risk can we focus on eliminating?

Well, we cannot eliminate market risk, so we are only left with the possibility of eliminating diversifiable risk. And being a finance geek, I like numbers to help me choose which project is the least risky. Let's look at an example first.

Assume that since you're my friend, I left you $100,000 to invest anyway you see fit and you're left with two possible choices. Choice "A" is to invest in a little stock we'll call "GE." GE has been around 100 years and is very steady and consistent, although not very sexy or glamorous when it comes to a crazy return. You can expect to earn 9% per year from GE.

Choice "B" is a little-known company called "Ola's Tapioca Mine and Tattoo Parlor." The main office is located in Key West, FL and they hope to franchise the concept throughout the country. They, too, expect to give you an 9% return on your investment next year.

So where do you invest and why?

Unless you have a real strong, strange urge for a new tattoo and some tapioca pudding, you will most certainly put your money into GE since there is far less risk and the return is exactly the same as a risky proposition. This is an investors natural reaction to avoid risk and maximize returns and the only way you'd consider "Ola's Tapioca Mine..." is if they had an expected rate of return greater than 9%.

But remember, greater return comes with greater risk. Let's call this risk "BETA."

Now let's also assume that the stock market has a BETA of 1.00, and we know that the average return in the stock market is about 9%. We need a number to show how much more, or less, risk is associated with our investment.

GE is old and consistent. When I hit YAHOO Finance and checked out their key statistics, their BETA was .75. This means that for every 1% the stock market moves up or down, GE will move 75% of the distance. So, if we expect the stock market to go up 10% next year, we would expect GE to go up 7.5% next year. Similarly, if we expect the stock market to go DOWN 10% next year, we'd expect GE to go down only 7.5%. So while our expected rate of return is the same as the stock market, our risk is actually 25% LESS. Hmmm..

Our Tapioca Mine might have a BETA of 1.5. This means that if the stock market went up 10%, we'd expect the Tapioca Mine to go up 15%, and vice versa if the market went down. In essence, our investment is 1.5 times riskier than the stock market and offers only a similar return. Not good.

There is a different figure we can use as well that capitalizes upon standard deviation, but that's not necessarily a blog type of entry. I just want you to be comfortable when you see the term BETA Coefficient going forward and recognize what it means.

Also recognize that BETA is utilized to compare projects that you are considering as a business, along with standard deviation and coefficient variation. If you'd like help with any project analysis, including PERT charts, please let me know as I have experience in these things and would be delighted to assist you.

Finally, recognize that you can get most of these figures for free from YAHOO Finance, CNNFN, etc. Research doesn't have to be expensive or time consuming.

Former Magellan Fund Manager and investing legend Peter Lynch often said his best source of research was his wife and his teenage daughters. They knew retail trends and hot fashion better than a 50-year old investment fund manager, so he learned to trust their judgment on what was hot and what was not. He simply put pen to paper to see if the numbers made sense, which they often did.

Use your common sense when looking at investment choices. Many times, you know something the pros don't or something they miss in their analysis; something you can use to make a lot (or save a lot) of money.

Next up: Positive and Negative Coorelation (not much of a teaser, but certainly a reminder to me of what the heck to write next week.)

Risk can be...well, risky!

For the last few weeks we've been hearing how much risk there is in the economy.

One of the key words being thrown around is "systemic" risk, and I thought it might be wise to analyze the two basic types of risk one faces when running or managing a business. For some readers this will be a refresher course on managing and measuring risk; for others, we're going to slap some formal terms onto things you probably already know. Consider it a free Finance course.

The first goal of ANY venture is to remove as much risk as possible from the equation. By doing so we increase our assuredness that our project or investment will be predictable. We like predictability since it helps us create reasonable, realistic figures that we can present to our banker, shareholders or business partners. The way to remove risk is by doing something called "diversifying." Many of you know that word from meeting with your financial professional and them telling you to diversify your portfolio. It's a fancy way of asking you to not own only one type of stock, but rather, many different types of stocks. This creates a layering effect, so that one investment goes down, another might go up. It's a way of offsetting one risk with another.

Any risk that can be removed through diversification is known as non-systemic risk.

Let's look at a pizza shop for example since it's Sunday and pizza goes with church and football.

A pizza shop owner wants to remove as much risk from his or her business as possible. What are some risks they face on a daily basis that can be tweaked or changed?

Costs are largely contained in ingredients, so if the cost of mozarella cheese goes up from one supplier, our owner can look to another, cheaper substitute. Similarly, if business is slow during the lunch hour, our pizza shop could expand into new products such as salads, sandwiches, finger foods, etc. If our pizza shop is in a large metroplitan area, they may decide to eliminate delivery altogether and save the cost of labor. Basically, anything that can be readily changed to keep costs down/revenue high is a non-systemic risk.

On the flip side of the coin, however, is "systemic" risk. This is risk that CANNOT be eliminated through diversification.

For example (and there are many) oil prices. There is absolutely nothing our pizza shop owner can do about the cost of oil, which ultimately results in higher produce costs. Similarly, minimum wage increases set by government bodies will have an impact on the bottom line and there is nothing our business operator can do about those either. Other examples include inflation, unemployment, acts of terror, war, election results, interest rates,etc.

So as business people, it is our job to eliminate or diversify ALL of our non-systemic risk while carefully planning for ALL systemic risk.

We are very good at the first part since we know our business forwards, backwards and inside out. But for some reason, we are not real good at the second part, whether it's a result of too little time to plan for this type of risk or we aren't really interested in figures like CPI, PPI, GDP, Prime Rate and unemployment figures (both locally and nationally.)

I'm here to tell you that if you are to be successful for the long-haul, you have no choice but to be concerned about systemic risk. Otherwise, you are living a lie even though you have every product that could appeal to any consumer in the world.

Make a plan that includes tracking interest rates, inflation figures and employment figures; whether daily, weekly or at the least monthly. This will help you begin to see where the economy is heading six, nine or twelve months from now. By doing so, you would have known that this crash was likely to occur and you could have applied for that business line of credit in May rather than scrambling now to shore up some extra cash. Maybe you held off on that new piece of equipment because you were too busy to stop by the bank and make a loan application. Now, the cost of the equipment has gone up due to production costs and you are having a tough time getting approval for the loan since lending is being restricted.

Plan for the long-run by analyzing systemic risk and run your business day to day by measuring non-systemic risk.

It's really nothing more than a study in Macroeconomics (systemic) versus Microeconomics (non-systemic.)

Next week we will uncover some figures that help us put a number to the amount of risk we're taking on.
