I'm having trouble figuring out the difference between the Close and Adj Close on MarketXLS tables for fixed income funds such as FNMIX. I thought the difference would be the distributions (which occur monthly in most fixed income funds) . According to Fidelity FNMIX has had the following distributions since 7/1/18. Date Per Share Amount Reinvestment Price 10/31/2018 $0.05972082500 $14.43 9/30/2018 $0.05642725800 $14.88 8/31/2018 $0.05971880500 $14.65 7/31/2018 $0.06082037100 $15.21 However the difference between the Close and Adj Close ( Close - Adj Close) is quite different on the day after the dividend. Date Close - Adj Close 11/2/2018 $0.00000000000 10/1/2018 $0.00000000000 9/4/2018 $0.00000000000 8/1/2018 $0.06183815002 It looks like the data is missing the last three dividends, and incorrectly computed the dividend on 7/31. Can someone tell me what I am missing?
