Are you a female undergraduate at Harvard? Do you want a chance to win $150? Harvard Smart Woman Securities (SWS) is hosting an investment competition through MarketWatch.org, a website that allows you to invest virtual money in the stocks of real companies, which you can check up on in real time.

"This competition is a great way for young women to gain stock exchange experience that parallels the real world in a risk-free way," said Linda X. Du '15, a chief development officer of SWS who led the creation of the competition. "Finance can seem like a daunting, male-dominated field, so we hope that this will allow the girls to get a feel for investing."

No experience is necessary, and all you have to do is create an account using the password "HarvardSWS." You will then be given $100,000 in virtual money to invest. Whichever participant sees the greatest increase in her portfolio between now and Dec. 7 will win $150; second place will be awarded $50.

Thirty-eight people have already joined the competition. You can enter either on your own or in groups of up to four people. The deadline is Saturday, Oct. 27.
