<prompt> Human: Im not great at stocks and such. I have a 403b from a previous job I have let grow on its own. Its in free fall with the recent stock problems and has lost about 10 recently about 3,000 which is about a years worth of growth. Should I leave it alone? Merge it with my current jobs? Change the investment profile? I know Im not supposed to make big changes when the stocks are down...but...it...keeps...falling... Thanks for any input in advance!Assistant: This is also my first big hit. Im just gonna let it sit for the next 25 years, and keep buying on schedule. Human: I guess I dont understand this process. Why am I putting money in something than can just vanish? Risk big, win big? Eek!  <response>: because historically it hasnt. historically its been a great investment over the long term, think in decades, not months or years.
