Late 20's guy here just starting in the investing world. Any advice? Have vanguard mutual funds in my Roth IRA. Believe I have around a 9% ROI on lifetime of the IRA (7 yearsish)
Stay with Vanguard and keep studying. Do not get crazy with your Roth IRA... you have decades of tax free, compound growth ahead of you. Equities with dividends are your friend. If you nibble on a risky investment, do it outside of a retirement account so that when you lose your money you can write it off of your taxes.
Vanguard is great... they are a mutual company that is owned by the investors. If they make a profit (they're a not-for-profit, but they're allowed to be profitable) they put it back into the organization to reduce the fees they charge client/owners for their investments. I can't say enough good things about Vanguard.
If you get professional help, actually writing a check to a fee-only financial advisor is probably less expensive than going to a fancy broker that will bury their charges by taking huge cuts disguised as fees in their investment options. There's a fiduciary rule kicking in in a few weeks that will require RETIREMENT account advisors to act in the interests of the investors over their own interests. It's hard to believe that the financial industry has been able to skirt this requirement... it will be interesting to keep an eye on it.
Study the financial details. Know revenue, earnings, P/Es, DIVERSIFICATION, dividends, dividend coverage ratio, exchange traded securities, trading volume, market capitalization, and so on inside out. Learn all of the definitions in Investipedia. Read the Wall Street Journal/Barron's and Investors Budiness Daily. Be skeptical of Cramer/Mad Money, CNBC, Bloomberg, Fox, etc.. There are a lot of sheep in their flocks that get slaughtered. But it's good to watch and learn the language they speak.
Investing in what you know is a good idea. But don't get overweighted investing in your employer(s) stock. Enron employees that poured all of their own worth into Enron stock experienced an epic financial disaster.
The financial sector performs pretty well over time. XLF, as well as the other SPDR sector ETFs, are pretty safe investments as far as equities go.
Ask lots of questions. Watch out for slick guys. If anybody promises high returns in an investment... run away. They're crooks.
