Tax Question

Greetings,

Let's say I put $10k into a stock. The stock starts going up fast, let's say 50% in less than 30 days. Now I have $15k in this stock. Can I pull my basis out, the $10k, without triggering a taxable event? And meanwhile keeping the $5k profit working in this same stock.

Also, follow up question, let's say I used this same $10k on another stock that also went up 50%. Can I pull the $10k basis out without triggering taxes?

Thanks!
