<prompt> Human: Looking at my account history, this all took place on 8312016. I see that the change in value on 9116 for the Deutsche SP 500 index was a positive 62.48 change, whereas the change in value for the blackrock SP 500 index was a negative -00.02 change. EDIT- this was the part that seemed shady to me.From what I can tell it also looks like the deutsche index had lower expense costs.. I have no idea what I am doing in regards to these funds so any and all help is appreciated. I can post a screen shot of all the investment options available to me if that would help.EDIT: It looks like the new fund actually has a lower expense ratio. I am not very smart. Thanks PF!  <response>: No, you shouldnt worry.
