21st Century Economics

Many investors today are interested in the high flying, fast growing and most profitable investments possible. An inviolate law of economics is that high profit comes at high risk. So far, no one has been able to break that law, although many have tried or thought they had. In the long run, it has proved to be true in every case.

Unfortunately, the high risk, usually expressed as a high beta value, can be misleading because many people do not understand that in the area of investments, if you lose 10% and gain 10%, you are NOT back where you started. Let’s take an exaggerated case:

Suppose you invest $1000 in a volatile stock. As it is prone to do, it whips up and down and in the first year after you buy it, it suffers a total of a 25% loss. Being high risk, it also can go up so in the second year it ends with a 25% gain. How much money do you have? $1000? NO! You actually have $937.50. It is down more than 6%! Here’s why.

The first year’s loss of 25% of $1000 is $250 so you end the year down by that amount to $750. Now you start the second year with $750 and go up 25% or $187.50 to $937.50.

You would have to have about 34% gain in the second year to just get back to your original investment.

Now let’s take a much more conservative investment with a low beta. In this case you start with your $1,000 in a blue chip or balanced mutual fund that has a 10 year average return of 10%. At the end of the first year, at that rate, you will have $1100 and at the end of the second year you will have $1,210. That is $272.50 higher than the volatile, high risk, high return stock - or 27% better!

Of course, you invest in the high risk stock because it has more positive net returns that used in this example. More likely is fluctuations of up and down 25% but with more ups than downs but even that can be misleading. Here’s why.

Suppose the stock, from July to January, goes down 25% and then back up 45% by June of the following year. If you were to read their ad or see one of those investment magazines, it would show you a “YTD Rtd” (Year To Date Return) of 45% in the first 6 months of the second year. So you put $1,000 into this stock in July. It goes down 25% by December and you end the year with a balance of $750. But you hang in there and watch it rise from January to June by a whopping 45% - wow! Hmmmmm wait a minute - what have you really got now.

$1,000 down 25% to $750 in 6 months and then up 45% for a second 6 months gain of $337.50 to $1,087.50 by July of the second year. You end the 12 months with $12.50 LESS than the buy that invested in the conservative stock at 10% annual return!

You can change the percentage numbers and shorten or lengthen the periods of time but you get the same result. If you have a volatile stock and it incurs a loss early on in your investment, you have to have a very hard working investment to make up for it later. For instance, if you invest in a stock with an expectation of getting 10% per year but in the first year you take a 10% loss, you now need to have an average annual return of 15.7% for the remaining 4 years to get the original expected 10% average return for the 5 year period. Look at the stock ans see if that is reasonable.
