ok. first of all, stocks and CD's are two completely different investments. You being younger and wanting a higher return, lets just scratch CD's out completely. (If you want a fixed income security, go with bonds, they will do well in the next year). Second, are you going to need this money in the near future or is this 30k invested going to stay invested for the next 5 plus years or even longer. Investing at 25, i believe this should be money you will not need to touch at all in the future, and let it grow. If you are unsure what stocks you might want, you can invest in mutual funds, which already predetermines what stocks are picked, combining this with bonds can help diversify your risk. Although, mutual funds do carry loads (fees) that wouldnt be there if you just bought stocks, I wouldjt recommend just picking stocks you want, there are programs that professionals use to determine the volitility of each potential investment and choose which works best for you. Your not going to get the advice you need on Yahoo!, i recommend contacting an advisor and let them know your situation. Make it clear that you want to know the fee structure of each potential investment, and do research, (contact multiple investment companies and determine the cheapest for you). If you want to start a small portfolio and invest lets say 5-8k yourself in stocks that you beleive will do well, i suggest going to etrade.com. Many of these stock trading sites will allow you to trade, manage, update and recieve vital info on your portfolio. This is an interesting way to invest and only cost about $8-$10 per trade. So you will want to make perminate decisions, you dont want to be trading every day or week, or even month. So for example take 8k, Do some research and find 10-15 stocks you find that may be profitable, all over the board if you want to. Meaning Large Cap, Mid-Cap, Small-Cap. If you want to make a replica portfolio and watch how your potential picks will go you can do it at yahoo finance, morningstar, msn.com, just about any site and build a portfolio. If you want some specific advice or example, here is my latest portfolio that i purchased in October 2006.
-Apple -Bristol-Meyers Squibb -DivX -Johnson & Johnson -Oceaneering Internat -PepsiCo -Mariott International -Genetech
My next investment will most likely hold...
-eBay -Mercury General -Versun Energy -Armor Holdings -AES... these are a variety of stocks, do some research, and put them into a replica, see how they do for a few weeks, Also none of these stocks are goign under all together, they should do well over the next year. G'luck
