But, there are some problems when we try this portfolio-building approach. We are using
historic data that may not be representative for the future trends. The UK official warning that:
“The price of shares can go up as well as down. Past performance is no guarantee of future
performance etc....”Thus, the fundamental assumption of overall long-term stable variances
and covariances can fall apart rapidly, and that means that the portfolio performance becomes
very unpredictable and more risky. It can become too complex a modelling exercise to be
conducted in-house.
Investment risk experts
Risk management is still an art as well as a science. We have seen the use of sophisticated
models based upon correlation between different risks and assets. Many of the parameters are
numerical and objective. These provide real benefits when applied properly. We also have to
realise that these tools only handle certain types of risks adequately, mainly market and credit
risk. When new products are introduced and increasing complex financial modelling overawes
us, we deem it fit to call in the investment risk experts.
If computers and automatic limit systems worked all the time, then no one would have to
go outside for specialist help, except for the occasional risk management and dealing system
supplier. Mechanical-type systems only account for a small part of the entire risk management
business process. Many companies do not possess all these skills in-house and there are reasons
why they must hire outsiders. See Table 3.6.
This means that in major change projects, some element of accountability and control are
reduced because of taking in outside help. Also, cost-effectiveness is not the top criterion in
these projects at all. In essence, it is ironic that we hardly place checks and controls over those
who are hired to control our errant staff.

More products and mathematical modelling techniques are brought on the market every year.
This creates a buoyant market in certain dealing areas. The prospects for derivatives and futures
contracts are bright in many ways, but what do they offer fund managers in the way of real
value? Many are confused as to the exact answer, so they bring in outside derivatives experts
to help them. Some of the problems lie in the complexity of these financial instruments, the
extreme leverage they can possess and the manner in which people have been mis-selling them.
The deep mathematical foundations underpinning derivatives and financial futures instru-
ments mean that more scientific knowledge is needed to understand them. Thus, a breed of
mathematicians and intellectuals sometimes known as “rocket scientists” or “quants” appeared
in various brokerages, banks and funds. Investment risk is not a question of solving solely by
