If I invest in index funds or other long term stocks that pay dividend which I reinvest, they don't need to be worth more per share for me to make a profit, right? That is, if I sell part of the stocks, it's GOOD if they're worth more than I bought them at, but the real money comes from the QUANTITY of stocks that you get by reinvesting your dividends, right?
Can I invest "small amounts" (part of paycheck) into index funds on a monthly basis, like €500, without taking major "transaction fees"? (Likely to be index fund specific... general answers or specific answers using popular stocks welcomed).
Is this plan market-crash proof? My parents keep saying that "Look at 2008 and think about what such a thing would do to your plan", and I just see that it will be a setback, but ultimately irrelevant, unless it happens when I need the money. And even then I'm wondering whether I'll really need ALL of my money in one go. Doesn't the index fund go back up eventually? Does a crash even matter if you plan on holding stocks for 10 or more years?
Does what I'm planning have similarities with some financial concept or product (to allow me to research better by looking at the risks of that concept/product)? Maybe like a mortgage investment plan without the bank eating your money in between?
