Do closed listings impact Featured Offer Percentage?

I am new to Amazon, but I am registered in the brand registry and I’m the only seller of my branded products. Usually my Featured Offer % is 100% but when an item goes out of stock it drops below 100%, I think because people look at the listing when it’s out of stock. I have one item that will be going out of stock in the next couple of days and I’m wondering what to do about this? If I close the listing then will people still be able to view the listing an cause my Featured Offer % to take a hit? Is that what I’m supposed to do? Thanks for any help you can give.
