There are many variables to figure out when deciding where to invest. First and foremost is when you think you may need the money. How to invest to use for a down payment on a house in a few years will be much different than investing for retirement. There also may be various tax advantaged plans to use. The first step will be to have a financial plan. Speak with someone who will help you with that and it may be the best money you ever spent.
Or to put it in other words, you need to figure out where you are, where you want to get to, look at the various options, and then figure out what works best for you now.
I will also point out, that you probably want to speak to someone that really understands your lifestyle. For the average American Joe, the primary financial concerns are children's college education and retirement. For many yidden, there's a lot more (and different) things, with different timings that go into the mix.
Also, flexibility is an important consideration. For example, when my oldest daughter was born I started investing for her in a special mutual fund which was called at the time American Century Giftrust. Little did I realize, that when it came time to enroll her into seminary, that money, which was titled in her name, would hurt us badly for Pell Grants. That's just one example, but I can name others, for unintended consequences of seemingly good plans.
