The following table contains the historic returns from a
portfolio consisting of large stocks and a portfolio consisting of
long-term Treasury bonds over the last 20 years. T-bills returns
represent risk-free returns. Analyze the risk-return trade-off that
would have characterized these portfolios. The following dataset is
also available in Excel format in Module 3 Resources on Canvas.
Returns in the dataset are in percents. For example, 31.33 means
31.33% per year.

(20 pts) Make a time series plot of the data
(5 pts each 25 pts total) Determine the following: Mean, Median, Standard deviation, Q1 and Q3. (25 pts)
Make a histogram of the data. Hint the year is not used, you need to determine how many years fall into each of the classes.
(7) What are your thoughts on the time series plot, i.e. trends etc.?
(8) Thoughts on the histogram i.e. shape of distribution etc.?

You receive a year-end statement from your broker that details your stock ownership over the years, and the total gain or loss over the holding period for each. You want to devise a method to make a meaningful comparison of the returns in order to determine which stock performed the best and which performed the worst. The problem is, the holding periods all have different starting and ending dates and are different lengths.

In: Accounting
When WorldCom Inc.’s former chief executive Bernard Ebbers was found guilty of participating
In one of the largest U.S. accounting frauds ever, the ruling sent a message to corporate
Executives: Professing ignorance won’t necessarily save you.
Mr. Ebbers, who died Feb. 2 at age 78, was a former gym teacher who rose to head a
Telecommunications Company with a peak market value of about $180 billion. In the late 1990s
And early 2000s, WorldCom improperly boosted profit by booking operating expenses as capital
Spending, which can be deducted from earnings in small chunks over time.
During a trial in 2005, he pleaded not guilty to accounting fraud and said he didn’t know about
The misdeeds. The jury didn’t buy it. His 25-year prison sentence “put an exclamation point behind the old phrase ‘the buck stops here,’ ” said Patrick McGurn, special counsel at proxy advisor Institutional Shareholder Services. The dot-com bust and accounting scandals at WorldCom and Enron Corp. helped spur Congress to enact the Sarbanes-Oxley Act of 2002, whose provisions include requiring a public company’s chief executive and chief financial officer to certify that financial statements are accurate. The scandals also hastened a trend toward more independent corporate directors willing to challenge CEOs. Charles Elson, who heads a corporate-governance center at the University of Delaware, has this epitaph for the WorldCom fiasco: “As bad as it was, some good came out of it.” The regulatory changes didn’t mean corporate scandals would automatically land CEOs in prison. The aftermath of the 2008 financial crisis was notable for a lack of CEO scalps. Corporate leaders, wary of prison, may have become more cautious and less likely to leave paper or email trails, said Peter Henning, a law professor at Wayne State University, in Detroit. Mr. Ebbers, who built WorldCom through dozens of takeovers, was released from prison 13 years into his sentence in December because of deteriorating health. He followed an unconventional route to the CEO suite. The second of five children, Bernard John Ebbers was born Aug. 27, 1941, in Edmonton, Alberta, in Canada. His father worked as a traveling salesman and mechanic. The family moved to California in the late 1940s. Mr. Ebbers attended a boarding school on a Navajo reservation in New Mexico. As a young man he held odd jobs as a milk delivery man and a nightclub bouncer. Twice he gave up on college because of poor grades. He graduated from Mississippi College, where he played basketball, with a degree in education in 1967. Early in his career, Mr. Ebbers taught physical education and worked in a garment factory. He later began buying motels, starting with one in Columbia, Miss., where he lived in a two bedroom trailer in the parking lot. When AT&T’s “Ma Bell” system was broken up in the early 1980s, small rivals began reselling long-distance service. Mr. Ebbers and a handful of investors backed a company called Long Distance Discount Service, later renamed WorldCom. Dubbed the “Telecom Cowboy,” he earned a reputation as a hard-driving boss. He began to borrow money from the company in the late 1990s and used some of it to buy company stock. As the company expanded, Mr. Ebbers said he relied heavily on experts. “I’m not an engineer by training; I’m not an accountant by training,” he told the New York Times in 1998. “I’m the coach. I’m not the point guard who shoots the ball.” WorldCom began to show signs of stress in 2000 as its share price sank amid the dot-com meltdown. Mr. Ebbers was fired as CEO in April 2002. Soon afterward, an internal auditor spotted accounting irregularities. After his ouster, Mr. Ebbers appeared at his Mississippi church. At the end of the service, he walked to the front of the church and spoke to the congregation: “I just want you to know you aren’t going to church with a crook.” WorldCom’s former chief financial officer, Scott Sullivan, who engineered the fraud and worked closely with Mr. Ebbers, was sentenced to five years in prison after cooperating with prosecutors. He testified that Mr. Ebbers knew of the accounting methods used. Mr. Ebbers insisted he was blind-sided by the fraud. “I know what I don’t know,” he testified in a federal court. “I don’t, to this day, know technology. I don’t know finance and accounting.” As a judge delivered the sentence in 2005, Mr. Ebbers hung his head and cried while hugging his wife, Kristie Ebbers, who filed for divorce in 2008. He drove himself to prison in a Mercedes the following year and spent part of his sentence as inmate No. 56022-054 in a low-security prison in Louisiana. He was later transferred to FMC Fort Worth, a federal prison hospital in Texas. Paul Watson, a Mississippi resident and former WorldCom investor, lost $135,000 when the company collapsed, and supports a relative who lost $2.2 million. Still, he said, he feels little anger toward Mr. Ebbers and thinks “others have done far worse and been punished less.”
