Quote from 2manywhiners:
go to a broker. you should ask an investment adviser what he/she thinks.
keep in mind what your risk tolerances are, and also that most advisers don't care about you unless you have a six figure account and allow them to buy and sell at will or do it often yourself.
Seriously, if you have experience yourself then why are you asking anyone on here about what you should do with a 10k investment?
If you don't care about losing 10k, why not try letting it all ride on GOOG or some other highly volatile stock? If you care about protecting your 10k, then maybe you should consider diversifying in mutual funds or ETFs.
My opinion, if one of your stock picks starts to tank (take into consideration that using only fundamental analysis as the lone entry guideline and over only a one month period is mostly considered unwise at best) don't hold the loser for several weeks. If you don't want to compound the fees, just sell it and let it sit as cash until the next month.
Best of Luck.
