"Stock" split for mutual fund - NAVs incorrectly recalculated
Re: Historical data for mutual fund CULIX/CULAX
When there was a “stock” split for the mutual fund CULIX/CULAX on 6/18/18, you calculated the changed NAVs before that date incorrectly. You applied the multiple for the split twice, rather than just once.
For example, before the split the 6/15/18 NAV of CULIX was $15.62. The split was 1:1.5625. $15.62 / 1.5625 = 9.9968 (rounded to 10.00). By dividing by 1.5625 twice you incorrectly adjusted the NAV to 6.3980 (rounded to 6.40).
The same holds for CULAX, for which the multiple was 1.5615.
You made the same mistake for dividends before the split.
