Bought a Share, It Dropped Instantly... Is It Just A Bad Luck? (beginner's quesiton)

I’m still learning the ropes of investing and mainly stick to the S&P 500, which works fine for me. I don’t stress over market dips. That said, I’m a bit confused about something. This morning, I impulsively put £200 into ENVB without knowing much about the company. I glanced at its recent price history, saw a sharp rise over the past few days, and figured, *Why not? I’ll buy in and sell in a couple of days.* Seemed harmless. But the moment I hit “buy,” the stock immediately dropped. Now I can’t shake the ridiculous feeling that my tiny investment somehow triggered the decline, like the company’s executives saw my £200 come in and said, *"Alright, time to cash out and blow it all on lunch."* I know it doesn’t work like that, but is there any scenario where a small trade like mine could actually impact the price? Or is this just bad timing on my part? https://preview.redd.it/wquk7ud03ile1.png?width=1079&format=png&auto=webp&s=63a4904e2d7fb326d2edad52e4f9b76aa82c2b95
