Advice on losing stock when remaining portfolio is earning

Hi everyone,

I am very new here to the subreddit as well as investing. I am a full time professional school student who came to school with about $42k and has taken out loans but also used some of that money to fund stuff without taking more loans. I used to have about $30,000 in CDs as my parents, who I LOVE to death and who have always encouraged me to save, suggested I do. They have an investment broker who helps them with stocks, but about March or so, I decided I was going to pull the $34,000, which had accumulated $4,000, over several years I'd imagine but was only getting 4% or so and when I realized the interest rates kept lowering to the low 3%s and with my small $2k portfolio with NVIDIA/Google/etc. and some index funds was doing well over the years, I put all $34k into a mix of things: primarily index funds with semiconductor companies (for AI), tech, and then like Walmart/Amazon (not as much amazon as that stock just fucking exploded with like 200%+ growth from my old portfolio that I played with since 2022.

This was around the time of the Iran War with the stock market at a big time low in like March'ish; since then I made about $10k profit which was absolutely fantastic. It has went up and down as it does with Trump's comments. Currently, I am probably more at a $9k profit but I also took out $1,500 to help fund life lol as I was pretty aggressive with my funds, but i am currently at $44k which is about $8k profit over the past couple months.

Then I got cute and started "diversifying" and stupidly bought a precious metals index fund at $1,500 which quickly lost about $400, it is now up to 1274 but what I didnt realize is that there is a $50/fee to sell. So I would effectively loose about $280 if I sold now, but those other stocks are legit making so so much more...

If you were me, what would you do? Sell it and eat the loss or wait for it to come back up a lil more before selling? I was also interested in dipping into day trading a little, would you recommend I test it with whatever I earn from selling this? like $1220 to just experiment with day trading?

Sorry for the long post, I am not super young by any means but very young to investing and stocks and I am super eager to learn more. This post is primarily for advice on my current situation.... I REALLY APPRECIATE ANY AND ALL ADVICE! 😄
