Wu says the group meets every week to discuss stocks that members would like to buy or sell.

"The treasurer or secretary sends out an e-mail to ask what stocks people want to talk about," he says. "Then they print up material on the stocks and discuss investing."

CWF uses the minimum $90 contribution from each member to invest. Some members opt to invest significantly more.

The larger the contribution to the group's financial pool, the more of a stake each member has in the club--and the more money he or she can make when the club makes smart stock picks.

Wu says the student with the biggest stake in the fund has about $2,000 invested--a nice chunk of money for when he decides to leave the club.

"We allow people to cash out," Wu says. "Seniors usually do this, and some enjoy a 50 percent gain."

They've ensured that type of gain with lots of smart picks.

In four years, club Co-Chair Parag Y. Shah '01 says an initial investment of $3,000 has ballooned to $20,000.
