I see a 162 for 1000 reverse split of SPB on 07/16/2018 as shown above.
But the stock open price on 07/16/2018 is 82.70, the stock close price on 07/13/2018 is 82.72.
This does not seem to be correct as a split of 1:8 surely should affect the stock price.
However, yahoo finance also shows a split of 162:1000.
So I am not sure whether there is indeed a split but somehow the price is not affected.
Could anybody let me know how to verify whether there is this split for SPB?
