But, a lot of people look at the surging stock market and want to get in on the fun. My best advice to you is to be patient and beware. The stock market is going up for a lot of reasons: decent corporate earnings, investors moving out of bonds, poor alternatives to stocks, etc. And most of all, the Fed's actions help make stocks attractive.
This can go on for a while longer, maybe a lot longer. But this cannot go on forever. Markets rise, and fall. If you are not invested in the market right now, and you wish you had gotten in a couple of years ago, well tough. You didn't and you can't go back. So you have to think about what might be your best move from here.
If you have money to invest, I'm going to assume you'll use mutual funds, maybe a blend of different types of stocks (large and small and domestic and international). And I'm going to assume you have a long term time horizon for this money you want to invest (like, 10 years or more).
Be patient with how you move this money into your portfolio of chosen funds. If you put everything you have into mutual funds today, what if the market tanks next month, you'll wish you'd waited, right?
My guess is that the market will have some sort of a nasty turn at some point during this year. It can't go up every day, every week, all year, right? And you'd like to invest at better prices than are available right now, today.
So, move your money into the market slowly, bit by bit, over several months. Like, 12 or even 18 months. Either automatically or manually, set it up so you invest a small portion of your money each month, for 18 months. Then, if the market tanks, keep investing on the way down. Even if the market goes down for a whole year, if you invest each month, think of the prices you'll get.
But be patient. And don't try to chase this market. It's gone up a lot. It's got momentum. But remember, when everyone around you thinks the market is a sure thing, be very very concerned. When it looks like there's no risk in the stock market, that's when we're near a top, and people are going to be taught another lesson about the risks involved in investing.
Good luck, ask questions, be skeptical. And, peace!
