Faceman is a member here. you can PM him with his name "Faceman".
your old company would have the information. you would contact their Human Resources deptartment, if they are large enough to have one.
Do you have any old paystubs? you surely must have SOME piece of paper with the account info on it, or was this ALL done digitally ( I HATE doing every darn thing digitally!!!!)
Once you find the name of the brokerage firm that holds the account, and the account number, you contact them and tell them you want to roll it over into ?
you should open an IRA somewhere. your bank will have simple IRA choices. Or , you can open one with Fidelity online. It is not hard to do. Once you have it openned, there is probably a way to make the transaction all digital. The bank might even do it for you, once you have openned an IRA with them.
when you do open the IRA, start contirbuting to it PRONTO! the sooner you do, the easier it is to get anywhere near what it takes to retire. AND, there are tax benefits to making deductiable contrinbutions to an IRA.
If you are self employed, you can do something called a Keogh (or some name like that). it's LIKE a 401k in some ways, but, again, ask Faceman.
If you set the IRA up to take an automatic deduction from your checking account, like a $100 per month, or whatever you can manage, you will be better off in the long run. It has to do with how you invest themoney in the IRA, and if it's in the stock market, the process of buying on a regular , monthly basis will give you a better overall price/purchasing ability than making one lump sum purchase, where you "guess" the best time to purchase stocks. Timing is important, but only the very knowledgeable can do it well. Us everyday schmucks just do it monthly, and in the long run, we win. IT's called "dollar cost averaging".
An IRA, if you didnt know this, is simply a type of account, like a checking account is a type, as is a savings account. What is actually IN the IRA is up to you. YOu could literally have Gold in your IRA, if you wanted. or cash, or stocks or bonds, or Mutual funds (which are just a bunch of stocks bundled together by a certain manager, and by a certain type or focus (i.e. international, or small companies, or emerging markets , or big co's.)
Is this helpful or am I telling you things you already know?
