Is anyone holding any QNC.v?

I recently inherited QNC.v stock and I’m unsure about the best strategy to handle it. I've only ever bought ETFs - VFV and XEQT. The price action has been incredibly volatile, which makes me wonder if I should sell now while there’s still value or hold onto it in case there’s further upside. I don’t have much experience with trading, so I’d love to hear from people who have dealt with similar situations before. How do you decide when to take profits versus when to hold onto a stock with wild price swings? Are there any specific indicators or market signals I should be watching?
