<prompt> Human: I was chatting with my coworker the other day, mostly about our 401K. Both of us are maxing out employer match, but she mentioned some other investments that she has. She told me that she invests a little each paycheck in the stock market, and it has worked out well for her been doing so for over 10 years. I am embarrassed to ask her about how she is doing this, as I have about 100week post-tax extra from some online sales, that I would like to invest in something long-term. So, anyone else that might have a clue, I assume maybe she is doing one of the following..1 Putting in a money market account, and periodically buying shares that she likes?2 Investing in some index fund, or mutual fund? 3 Something else I am not aware of...I am leaning towards 2, as she mentioned that its very low effort... but I am still confused. Are there online accounts where I can just dump money every few weeks, and it will be automatically invested into funds I choose? This is how my 401k appears to work.Assistant: You can have a regular brokerage account that you invest though, but these are taxable and probably not worth doing unless you are already maxing out tax deferred retirement accounts like you 401K and Roth IRA.Human: I have setup through work which they deposit company shares in each year RSUs. But my question is that she seems to be putting this money into something that automatically invests it for her, like buying index funds or something at certain intervals I think  <response>: I am not sure I understand your question. When you contribute to your 401K each payroll it should automatically get invested into the index funds you choose.
