I have a IRA from 2 years ago where I put the full $5,500 in right before taxes and have not done anything with the account since then (very anti-Mustachian, I know).
I'm thinking I will now put the full account into Vanguard index funds, is there any reason(s) it would be a good idea to either put the entire $5,500 in these accounts asap versus layering it in over the next 6-12 months?
