Simulation Week 6 – Logistics

The simulation run is complete this week.  Please get your week 7 input in asap.  I will try to have it run by Monday night if all input comes in.

There’s a recurring problem with input that I have to ask you to check for rigorously!  If you accidentally order a large amount of production, such as 35000 instead of 3500,  you will be hit with large penalty fees, and will have an enormous amount of inventory, since demand averages around 2400 per week.  That is what happened to the Lions in the Central division when they went $1M in the hole.  When you send me your spreadsheets, and I create the input files, I try to have a look, and I have warned some of you when it looked suspicious.  But sometimes I miss it.  That is what happened to the Lions.

The problem is, the program won’t handle numbers that are too big, such as losses over $1Million.  so to make it run after that, I have to go in and change numbers in the history file to -$999999.99, which actually distorts the results for everyone in that division.
I don’t want to have to modify the program to handle this type of error– it would be a big job.  It affects both the report (which I did fix) but also the history data which is passed to the next week, and also the computer input to the next week’s run.   Because of the problem for the Lions I am having to modify the history next week as well.

SO PLEASE CHECK YOUR PRODUCTION INPUT FOR THE CORRECT NUMBER OF DECIMAL PLACES! THIS IS ON THE FIRST DECISION SHEET IN THE SPREADSHEET!

Thanks a lot!

Here’s an article about the relationship between hedge funds and ordinary mutual funds.

Concern increases over ‘side-by-side’ managers

By Eleanor Laise
WALL STREET JOURNAL

A growing number of money managers are juggling multiple roles, handling plain-vanilla mutual funds for mom-and-pop investors as well as hedge funds for wealthy individuals and institutional investors.

Regulators and lawmakers have raised concerns about the trend, saying it could lead managers to favor deep-pocketed hedge-fund investors over the smaller fry investing in mutual funds. Some major fund companies, including Vanguard Group, staunchly defend these so-called “side-by-side” management arrangements. Others, such as Fidelity Investments, avoid the practice. Even new academic studies are divided on the issue of whether small investors are well-served by side-by-side management.

For fund companies, hedge funds — private investment pools for wealthy and institutional investors — can be much more lucrative than mutual funds.

Mutual funds now sharing managers with hedge funds include offerings from Vanguard, Pioneer Investment Management, Nationwide Mutual Insurance Co.’s Gartmore Global Investments and Ameriprise Financial Inc.’s RiverSource Investments. Such arrangements account for a small but growing slice of the fund universe, industry experts say. There are 124 individual portfolio managers simultaneously running mutual funds and hedge funds tracked by investment-research firm Morningstar Inc., compared with 112 last year and fewer than 60 in 2002. About $448 billion was invested in actively managed stock mutual funds run by companies that also managed hedge funds in 2004, according to Scott Gibson, an associate finance professor at the College of William & Mary’s Mason School of Business.

Many managers in recent years have left mutual-fund firms for the bigger paychecks and lighter regulation of the hedge fund world, and defenders of side-by-side management say that it helps mutual-fund companies retain talented employees and access a broad pool of top money managers. But critics say the practice gives managers an incentive to favor hedge funds with their best investment opportunities and distracts them from running their mutual funds.

A number of major fund companies steer clear of the practice. American Century Investments offers a traditional mutual fund that uses hedging strategies, and such funds “are a better deal for shareholders,” said Phillip Davidson, a senior vice president at the firm. Fund giant Fidelity has no in-house hedge funds and prohibits managers from running outside ones.

Other major players, however, defend side-by-side management. “It allows us to look at a very broad universe of managers and hire the best that we can find to run money for our shareholders,” said Joe Brennan, principal at Vanguard.

There are several ways that moonlighting managers can favor hedge funds over mutual funds. A manager might sell shares of a stock in his hedge fund before his mutual fund because he knows the sale could drive the price down. Instead of assigning a trade to a particular fund at the time it’s executed, a manager can “cherry pick” trades. He may make a trade in the morning and assign it to the hedge fund or mutual fund later in the day depending on its performance. And a manager who has access to a limited number of shares of a hot initial public offering might favor his hedge fund with them.

Shorting stocks, a strategy often used by hedge funds that typically involves selling borrowed shares with the hope of buying them back later at a lower price, can also lead to potential conflicts.

The SEC doesn’t dictate how managers should address these potential conflicts, and practices can vary widely among managers who run both hedge funds and mutual funds.
