<prompt> Human: 23yo and just opened a Roth w Vanguard. I have enough for the full 5500 but I was looking for some advice before I deposit.Given what the market is doing now, should I deposit 2750 now and wait it out to see if it goes any lower? Or should I dollar cost average around 500 each month? Or lastly, should I just deposit the 5500 all at once? Would appreciate any advice  <response>: Dont try to time the market. Statistically speaking, investing as soon as possible beats DCA.
