Update: It turns out the Stocks app has been replaced by a "POOF" icon in the folder I had it stashed in. Not really my idea of hiding an app if it's just replaced with an arbitrary icon.
I would have just edited my previous post but the eiC app doesn't allow attaching pics when editing posts.
EDIT: Using the "Unhide all Apps" function didn't unhide the apps I hid using this app. The respring caused the first "dark respring" I've had in a few weeks. I'm not sure how this app got through to the App Store. I've deleted the app and did a hard reset and the Stocks app is still "poof." It doesn't show up in Spotlight either.
