Roblox hitting low RSI

I am a teacher, and my students mention Roblox every day to me. From my middle school students to my 2nd graders, I think Roblox is a good buy. Especially right now, since it has hit the 30 mark on RSI. I am not a financial advisor, nor an investment expert. I am still learning, but so far I try to follow popular trends on RSI and MacD. Please feel free to share your thoughts on this as I am open to learning what others have to say about Roblox. Thank you!
