The risk of an investment is described by both the probability and the potential amount of loss. The risk of an investment-the probability of an adverse outcome-is partly inherent in its very nature. A dollar spent on biotechnology research is a riskier investment than a dollar used to purchase utility equipment. The former has both a greater probability of loss and a greater percentage of the investment at stake.
Projects are usually undertaken to either solve a problem or take advantage of an opportunity. The probability that the project - even if precisely executed - will complete on time, on budget, and on performance is typically small. Project management is utilized to increase this probability. So in a sense, project management is risk management.
Risk managers and investment bankers and actually, all kinds of investors took on more risk than they expected. So there was a failure of risk management. There was a failure to recognize how much risk there was in some of these securities that people bought.
Given the central role of effective, firmwide risk management in maintaining strong financial institutions, it is clear that supervisors must redouble their efforts to help organizations improve their risk-management practices...We are also considering the need for additional or revised supervisory guidance regarding various aspects of risk management, including further emphasis on the need for an enterprise-wide perspective when assessing risk.
If we face recession, we should not lay off employees; the company should sacrifice a profit. It's management's risk and management's responsibility. Employees are not guilty; why should they suffer?
Unlike return, however, risk is no more quantifiable at the end of an investment that it was at its beginning. Risk simply cannot be described by a single number. Intuitively we understand that risk varies from investment to investment: a government bond is not as risky as the stock of a high-technology company. But investments do not provide information about their risks the way food packages provide nutritional data.
A realistic definition of risk recognizes the potential loss of capital through inflation and taxes, and would include at least the following two factors: The probability that the investment you chose will preserve your capital over the time you intend to invest your funds. The probability the investments you select will outperform alternative investments for this period.
It was our use of probability theory as logic that has enabled us to do so easily what was impossible for those who thought of probability as a physical phenomenon associated with "randomness". Quite the opposite; we have thought of probability distributions as carriers of information.
Too often, business schools teach academic crisis management theory, if that, but given the diverse and unique nature of crises, all the theory in the world will not help you manage an actual crisis unless you know the basic mechanics.
You can teach all sorts of things that improve the practice of management with people who are managers. What you cannot do is teach management to somebody who is not a manager, the way you cannot teach surgery to somebody whose not a surgeon.
The more evolutionary theory gets called an atheistic theory, the greater the risk that it will lose its place in public school biology courses in the United States. If the theory is thought of in this way, one should not be surprised if a judge at some point decides that teaching evolutionary theory violates the Constitutional principle of neutrality with respect to religion.
The essence of investment management is the management of risks, not the management of returns.
Most of the time, your risk management works. With a systemic event such as the recent shocks following the collapse of Lehman Brothers, obviously the risk-management system of any one bank appears, after the fact, to be incomplete. We ended up where banks couldn't liquidate their risk, and the system tended to freeze up.
I do believe that India needs a lot more foreign direct investment than we've got, and we should have the ambition to move in the same league many other countries in our neighborhood are moving. We may not be able to reach where the Chinese are today, but there is no reason why we should not think big about the role of foreign direct investment, particularly in the areas relating to infrastructure, where our needs for investment are very large. We need new initiatives, management skills, and I do believe that direct foreign investment can play a very important role.
Rather, risk is a perception in each investor's mind that results from analysis of the probability and amount of potential loss from an investment. If an exploratory oil well proves to be a dry hole, it is called risky. If a bond defaults or a stock plunges in price, they are called risky. But if the well is a gusher, the bond matures on schedule, and the stock rallies strongly, can we say they weren't risky when the investment after it is concluded than was known when it was made.
In investment management today, everybody wants not only to win, but to have a yearly outcome path that never diverges very much from a standard path except on the upside. Well, that is a very artificial, crazy construct. That's the equivalent in investment management to the custom of binding the feet of Chinese women
