I am guessing by Dr Death you are referring to Alison Watkins. Let's take a look at her tenure at GNC.

Her start date was July 30 2010 and she left in January 13, 2014. In that period GNC was up 53% vs the ASX200 which was up 15%. So the stock outperformed the market by 38%.

This includes the large fall GNC suffered due to the takeover being rejected by Joe Hockey and the FIRB. This is hardly Alison Watkins fault. If we look at the stock performance and exclude the fall due to the takeover being rejected, then GNC was up 111% vs ASX200 up 18.67%. Outperformance of 93%!

So either way your look at it...I don't think you can say that her tenure was bad for the stock.
