Noob with 5k to invest

[Holt64]

I’m a true noob here. I apologize ahead of time if I say anything that’s stupid or maybe obvious. I’ve spent 5k investing in Nvidia, chipotle, and scmi. Unfortunately, that was just 5 days ago and I’ve been losing ever since. I first thought of course is to cut my losses and sell, but maybe the smart thing to do is to diversify more so instead of just three stocks have 20. Even though I only have 5K to spend. I joined motley fool in the hopes that I could get some advice for where to invest my money but things seem to be moving so fast that one day a stock will be recommended when the next day it won’t. I feel kind of like a fish out of water here. Any advice I could get would be greatly appreciated. Should I just stick with what I have for a while and just handle the downturn sit on my hands so to speak? Or sell off some of my stocks and diversify.
