Shilton Capital, owned by flamboyant billionaire Travis Shilton, has a reputation for managing risk well. The firm operates several hedge funds and partnerships, generating huge returns with risky strategies that always seem to pay off. Shilton hires the most creative portfolio managers he can find, then jets off to Switzerland or Brazil to be seen in the presence of the world's glitziest people. Paul Miller, as staid as Shilton is flighty, handles the day-to-day operations at Shilton Capital.
The bulk of Shilton Capital's assets are invested in five portfolio strategies: a hedge fund that seeks to profit from currency fluctuations, a market-neutral hedge fund, a real estate partnership, an enhanced index hedge fund, and a partnership that buys bonds of companies in financial distress. All five strategies have generated excellent returns over the last year.
The following discusses one hour at Shilton Capital:
Charlene Hatchett manages a hedge fund focusing on foreign currencies. She buys currencies she considers undervalued, mostly those in countries whose economic growth potential is not reflected in the global market, and sells overvalued currencies in forward contracts in an effort to cash in on the fluctuations. During her first hour at work, Hatchett has been buying up the drang, a currency used in Extralatia, a small African country with a booming economy and an increasingly talented and educated workforce she believes is not acknowledged by the global business community. At 5 p.m. Extralatian time, or 10 a.m. Eastern time, a military coup in Extralatia's neighboring country, Warmongaria, sends a flood of refugees running toward the Extralatian border. The new military governor of Warmongaria immediately threatens to invade Extralatia's capital if the country allows in the refugees, many of whom are of Extralatian descent. With a few quick phone calls, Hatchett learns that two multinationals near to announcing large development projects in Extralatia are rethinking their plans because of the unrest. The political situation in Extralatia is dodgy at the best of times, and Hatchett is concerned that recent developments will wreak havoc with the currency.
Mitchell Stone runs a market-neutral sector hedge fund that takes long positions in securities Stone considers undervalued and short offsetting positions in expensive stocks in a couple of key industry groups within the industrial sector. Stone expects the stock market to decline, so he wants to seek alpha through stock selection and wash out market returns. Most of the long positions represent companies with increasing market share and strong finances, while the short positions generally represent companies with weak balance sheets, which have been punished by a choppy, volatile market in recent weeks. Today, the market opens up strong on higher-than-expected growth of the gross domestic product and optimistic news about industrial activity from the Federal Reserve. The entire industrial sector rallies, with the weakest companies -- those most heavily punished in recent weeks -- leading the way. Stone's long positions are doing well, but his short positions are getting killed, more than offsetting gains in the long positions.
Carter Wainwright's real-estate partnership owns a mix of industrial and retail properties across the Eastern Seaboard. Vacancy is low, and rental rates are rising. But at 10 a.m., Wainwright learns that the state legislature just passed a new inventory tax that will make it more expensive to store goods in Massachusetts. Several large industrial concerns immediately start trying to back out of contracts to use a half-dozen huge, newly constructed warehouses in Boston, properties expected to provide the bulk of the partnership's revenue growth over the next year.
Lisa Cline's partnership owns bonds issued by a number of troubled industrial and consumer companies, all of which pay yields well above the market average. At 10 a.m., Canton Metals files for bankruptcy, and Cline's preliminary analysis suggests the company will default on its bonds, which represent about 10 percent of the partnership's holdings.
Max Campbell is having a fine day. He attempts to beat market returns by using leverage during periods when he expects the market to rise, and using futures contracts to hedge market risk during periods when he expects the market to fall. He targets a return of 150 percent of the index in up markets. Campbell is bullish at the moment and highly leveraged, and the solid economic news has sent the market soaring.
Hatchett, Stone, Wainwright, and Cline arrive at Miller's door at roughly the same time, panicking because they do not know how to address the risks. He meets with each one and recommends the following, in turn:
- To Hatchett: Since trading in Extralatian currency has been temporarily suspended, she should buy the currencies of neighboring countries in the region in an effort to hedge her risk.
- To Stone: He should sell some of his long positions and use the proceeds to cover the worst of the short positions.
- To Wainwright: He should do nothing.
- To Cline: She should liquidate her Canton bond position immediately for whatever price she can get before demand dries up altogether.
In attempting to fix the problems in Shilton Capital's risk-management system, which issue warrants the least attention?
A) | Inadequate stress testing. |
|
B) | Shilton's absentee ownership. |
|
C) | Failure to hedge away risks. |
|
D) | Lack of a risk-management committee. |
|
Answer and Explanation
As long as Shilton has a man he believes is competent in charge and a comprehensive plan in place, his presence at the office is not required. Many people own businesses and let others run them. The issue here is the process, not the company owner. Good ERM systems will select the best possible risk models and decide in advance which risks to ignore and which to hedge. The Shilton Capital system did neither. A good risk-management system will have a committee to oversee the process and ensure that proper stress testing is performed on all risky investments.

All of the risky events discussed above could recur. Current mitigation efforts aside, going forward, which analyst's risk would be most difficult for Shilton Capital to hedge away?
Answer and Explanation
While political risks cannot be hedged directly, Shilton Capital could address Hatchett's issues through insurance, currency swaps, or a combination of both. It is impossible to know exactly what could happen, but trouble comes when the currency falls for whatever reason, so the key is creating a hedge in the event that the currency falls, rather than trying to predict which disasters to prepare for. Stone's risks could be hedged with options, and Cline's could be hedged with swaps, though both techniques would eat into the profitability of the strategies. Wainwright's political risks would be extremely difficult to hedge away. It is very difficult to hedge away the risks of political change or a change in customers' perceptions of the market.
To best prepare for events like those faced by Hatchett, Shilton Capital should have: A) | calculated an incremental VAR. |
|
B) | set up a currency swap. |
|
C) | addressed sovereign risk through credit derivatives. |
|
D) | calculated return over maximum drawdown. |
|
Answer and Explanation
Nonfinancial risks are difficult to measure, and a VAR is only as good as the estimates used to derive it. Return over maximum drawdown is not relevant here, nor is sovereign risk, which reflects only the government's willingness to make good on its debts. The best option among those presented would be a currency swap, which could be used to hedge against declines in the value of Extralatian currency.
Which of Miller's proposed solutions makes the least sense? Miller's instructions for:
Answer and Explanation
Miller's instructions for Stone are a blunt but effective way of controlling the damage. The actions may seem drastic, but they will go a long way toward mitigating the risk. The risk Cline faces is actually something the company could plan for and hedge away. But once the bankruptcy announcement hits the streets, selling out is a logical action that caps downside risk. Wainwright's problem cannot be easily hedged away. Doing nothing may be the best option, particularly considering these are not problems the company can address without a lot of time and negotiation. However, the advice to Hatchett was bad. If Extralatian currency falls, currency in neighboring countries is unlikely to rise, and may fall in sympathy, or be affected by the same political issues. As such, a better hedge would be to attempt to sell those neighbors' currencies forward before they fall. The strategy isn't perfect, but it could counteract some of the risk. As the instructions currently stand, Hatchett would be doubling down on her bet, which exacerbates the risk rather than mitigating it.
Stone isn't happy with Miller's advice on how to manage the increased risk of his portfolio, and he has several ideas of his own regarding how to manage such risks in the future. Which of Stone's proposed solutions would be least effective? A) | Purchasing out-of-the-money call options on the shorted stocks. |
|
B) | Doing nothing, because the company's risk is already partially hedged. |
|
C) | Establishing notional position limits for each security in the portfolio. |
|
D) | Using scenario analysis to stress-test the portfolio. |
|
Answer and Explanation
Purchasing out-of-the-money call options would presumably allow Stone to cover his short positions at below-market rates in the event of a major rally. Scenario analysis would be an excellent idea for this portfolio, as the effects of many different economic scenarios could be calculated with some semblance of accuracy. It doesn't hedge away risk, but good scenario analysis could quantify the risk, making it easier to hedge or manage. Doing nothing is a counterintuitive solution, but it has merit because of Campbell's investment strategy. In the event that unusual increases in stock prices overwhelm Stone's market-neutral model, Campbell's investments are likely to rise. Campbell's portfolio is not as concentrated as Stone's, but it does have some risk-reduction features in the context of Stone's portfolio. However, notional position limits on securities would be unlikely to help, because Stone's portfolio is concentrated in one sector, and in the situation portrayed above, all of the stocks moved in the same direction. When all of the stocks tend to move in the same direction, assigning limits to the size of each stock position will have little effect on the overall risk of the portfolio.
Wainwright's current problems are best explained as:
Answer and Explanation
Active risk is a measure of market risk relative to a benchmark, which is not applicable here. Sovereign risk reflects the chance that a foreign government will not honor its obligations, while credit risk reflects the possibility of default, neither of which gets to the heart of Wainwright's problems. The trouble here is model risk, because Wainwright's model apparently did not consider the political risks of a tax change.
