<prompt> Human: I work at a Veterinary clinic and my bosses married has been talking a lot about penny stocks they want to buy. Im interested in the idea of investing and have a couple stocks in mind, but I dont know how to definitively pick what to look for, red flags, signs of growth, etc or where to go to actually pay for them. Some advice?  <response>: Since youre only 19, I would suggest opening up a Roth IRA with Fidelity since they have low minimums to open an account. If you have at least 1000, you can open one with Vanguard as another option. Both of these have low feesexpense ratios which will save you more money over time. Youre very young, so you have many years of compounding interest ahead of you! Not sure on what your incomeexpenses are, but if you could put even 100 a month into this account and then gradually increase your contributions over the years as your income hopefully increases, you will be way ahead of most people! Keep in mind, this is for a long term investment.
