We've heard it all ad nauseum. How many have cited this quotation from the Department of Labor: A “1 percent difference in fees and expenses would reduce your account balance at retirement by 28 percent”? How many financial advisors misquote a controversial 20-year-old study and say “asset allocation accounts for 92 percent of a portfolio's investment return?” Barely a day goes by without some investment blogger or product salesman using one or both of these pitches.

Would you be surprised to discover these bromides are nothing more than urban legend? 

An August study from the Wharton School at the University of Pennsylvania turns the 401(k) universe on its head by showing—while fees and asset allocation do have a nominal influence in achieving investors' retirement goals—often overlooked factors have greater primacy. Astute financial advisors have long known of these important ingredients: investing early, investing more and retiring later.
