Saving for retirement without employer sponsored plan
I'm looking for ways to geared to save for retirement, not general investment. Many mutual fund companies offer a range of target retirement funds for different retirement dates (usually in increments of 5 years). These are funds of funds, that is, a Target 2040 Fund, say, will be invested in five or six different stock and bond mutual funds offered by the same company. Over the years and as the target date approaches closer, the investment mix will change from extra weight given to stock mutual funds towards extra weight being given to bond mutual funds. The disadvantage to these funds is that the Target Fund charges its own expense ratio over and above the expense ratios charged by the mutual funds it invests in: you could do the same investments yourself (or pick your own mix and weighting of various funds) and save the extra expense ratio. However, over the years, as the Target Fund changes its mix, withdrawing money from the stock mutual funds and investing the proceeds into bond mutual funds, you do not have to pay taxes on the profits generated by these transactions except insofar as some part of the profits become distributions from the Target Fund itself. If you were doing the same transactions outside the Target Fund, you would be liable for taxes on the profits when you withdrew money from a stock fund and  invested the proceeds into the bond fund.
