at least enough to make a measurable return?

also what would be the best market? should i go al DOW NASDAQ or should i mess with forex/ commodities as well? maybe a mutal fund?


or would it be best to just stick it in a CD, im willing to take risks but in the end i would take steady growth over a one night boom and bust
the other investment would be in a high end pc to grow my graphic design bussiness, however that would take up all of my money

Answer
3000 dollars is enough to do good investment. I would suggest you to invest in shares. Check the website http://money-review-site.com/shares.html
to learn more on shares and stock trading and how to select the best stocks.
Hope it helps

I have 3000 dollars to invest in a stock or stocks, what do you suggest?

Answer
All the answers you've received (so far) will help you lose your money (quickly).

A. Forex.... great if you're an experienced trader. Keep in mind 90% of all Forex traders lose their money. On the ones that "win", they lose 40% of their trades (on average).

B. Stocks. Never invest in anything you don't understand & never take tips (from anyone or sourse).

Put your money in a savings account for a year. Take this time to learn investing. Learn "asset allocation". Just plain read as much as you can. Then (in a year) start investing. You'll know what to do that's best for you!
