Definitions
A risk can be
defined as ”A potential of gaining or losing something of value.”
or ”An exposure to the chance of injury or loss.”
Personal risks
First I would like
to say that risks affect on you in many different levels. For
example, they affect on you through corporations, nations and global
events like wars. I will keep things in personal level. Humans are
very good in understanding risks related to their survival.
Especially, when their intuitive decision-making systems are on. You
can avoid an imminent threat to your survival without even noticing
it. For example, changing your direction from the normal route,
because of something is not feeling right. Survival in these cases
means not hurting yourself physically in an imminent danger. You are
not good in avoiding long-term risks. Modern world has less imminent
threats than your brain thinks. This creates many problems that even
the risk management experts do not understand.
You have many
personal risks other than risks of physiological harm. Financial risk
is maybe the most common risk you think about. Losing your job, or
inability to pay your debt can cause you harm. You may lose your
reputation if you do something really stupid or someone spreads
rumours about you. You also have a risk of not being able to adapt to
the changing world. Doing what you have always done before is your path of least resistance. Changing things is hard,
even when it is necessary. People are also increasing their
technology risks, because their dependence on technology is rising.
Personal risks can compound in a long-term. Taking small, but
unnecessary risks without suffering the consequences fast may lead to
severe problems later on. For example, eating crappy food may not
cause you any harm for decades, until one day you get a heart attack
without any warnings.
Risk Management
Risk management is
about probabilities. You need to understand them to
understand risk. Repeatable events with fixed probabilities are
easier to understand. For example, risks at the roulette table and
lottery are fairly easily quantifiable. When you cannot calculate a
probability of something happening, you cannot really understand
risks. Uncertainty is not well understood. Managing risks without
understanding power laws is one of the most common causes of
financial destruction for institutions and in a personal level. The other common
cause is not understanding complex systems and the second order
effects in them.
You have to
consider your risk appetite too. Some people cannot sleep well with
moderate risks in their lives and some people cannot sleep well
without them. Risks are not all bad things. Progress comes from
taking risks. Some of them are managed and some of them are not.
Humans have developed as a race by avoiding risks concerning on
survival. Risk-seeking is about functioning against your basic
instincts. It is hard, but many times worth all the effort. When you
understand the risks you are taking, it is easier to get better
results. You have to ask yourself some questions to understand risks
better:
- What are the consequences of not doing it? What will it cost you? What are the unwanted outcomes that can come true? How will you react if they happen to you?
- What are the positive consequences? What will you benefit? How will you react? How do you feel about the outcoming benefits now?
Risks can also be
quantified in terms of impact of their consequences. You should use a
simple scale in how you want to rate the impact of the risks. Make it
reasonable. For example, you can use a three-level scale of impact
for risks. Risks with high, medium or low impact. Think about high
risks all the time. Risks with medium impact are not that important,
but you should check them regularly. Low risks are not that relevant.
You should still check them occasionally. You should also remember
that low and medium impact risks can become high risks through
compounding. In this case, it means taking many small risks many
times.
Asymmetric risk
There are two
kinds of asymmetric risk. Good ones and the bad ones. An asymmetric
risk means that the reward is a lot bigger than the risk taken, or
the reward is a lot smaller than the risk taken. In other words, the
expected payoff is high or low, depending on the risk taken. Nobody
wants to take an asymmetric risk where the expected payoff is crappy.
Most often, this happens because the risk taker do not understand
what he/she is doing. This happens to the most respected experts too.
Especially, financial market participants do not understand risks.
One reason is that they haven´t noticed the power laws in the
markets or understand them. Many assumptions about the returns in the
financial markets are made by thinking through a normal distribution.
The problem is that returns in financial markets do not really
realize through them. Most of the profits are made with a small
number of stocks or during the small number of days, etc. In other
words, extreme outcomes in financial markets have higher
probabilities than using normal distribution tells you.
It is easy to make
a statement that you should avoid all the asymmetric risks, where the
downside is enormous compared to the expected payoff. For example,
not going to see a doctor, when you have a severe chest pain. Not
going to a doctor can cause a death and going to the doctor can save
you. You can also take lots of asymmetric risks where the
probabilities are against you. When expected payoff is high, you need
smaller amounts of successes. This doesn´t mean that all the risks
come true and payoff is always high. You should be ready for many
losses with these kinds of risks. Overall, the expected payoff will
be good in the long run.
