Hi another question!  My husband and I both work for the postal service-and we are now putting in just the matching amount in our tsps.  What I want to know is if we both have to be diversified in our roths.  For example we both want index funds-so if I have lets say, a small cap and emerging markets in my roth and my husband does total stock market and a reit in his, is this still considered being diversified or do the four funds have to be in each of our individual  roths?  Thanks so much-I really appreciate you help!!!
