<prompt> Human: Ive often heard here that IRAs should be prioritized over 401ks because most 401ks dont have the best options. I assumed this was true as the small companies ive worked at before all had funds with 1 or 2 fees.Well i just got a job at a fortune 100 company and to my surprise my 401k has access to funds that are so good i didnt even know they existed. For example i can invest in VIIIX which has an expense ratio of only 0.02Is this normal when working for mega companies? It it just an economy of scale thing that gives them access to these funds?  <response>: Do most large companies provide excellent 401k fund choices?The larger the company the more likely it is to offer the institutional share class of the big funds to their employees. Thats only a general statement though - it depends on the company.It it just an economy of scale thing that gives them access to these funds?Yes.
