Why do stocks go down even when their reports are all mostly positive/beat?

Why do stocks go down even when their reports are all mostly positive/beat? Am I just fucking stupid? What am I missing? You know, I'm not this AI/Chip sector guy, but I decided to dabble with my money a bit, chose Broadcom to invest for a year or so and later decide what to do next. Researched the stock (among other things) for about a month, after looking at numbers and expectations, I was expecting that the stock will do well and in 12 months, possibly more , I'll sell at 40-200% profit (depending whether I'll start drinking pills). So here I was, after investing like 10% of my portfolio, looking at September 2 earnings report and my reaction was this - **Holy shit, they actually beat it, I was right after researching it, they actually had good results (**I will provide information below for context): *Broadcom reported non-GAAP EPS of $3.32 against an expected $3.22 and revenue of $29.6 billion, up 86% year-over-year, driven by a 221% surge in AI semiconductor revenue to $16.7 billion****,*** *FCF and operating margins were described by the company as "records".* So I was like - **okay, at the very least it will go up after today**(September 2nd) - **IT FUCKING DID NOT, IT WENT DOWN 6%**. Let's be clear, I never pay much attention to these things, it's only 6%, but seriously? What is the logic behind this? That's all because of guidance that wasn't beaten(i.e approximately $34.8 billion vs. analyst expectations around $35.0B)? I might be naive and I understand that Broadcom also depends on those fat guys (Googly, Open-Air, Off-Meta, Fruit, Anthrodick etc.) but what am I missing? Oracle, which I'm not invested in, also did great in their earnings yesterday, they are also down. I know it's about the waiting game, but I'm genuinely looking for that one, simple answer to **Why do they go down after earnings are positive/beat**? I'm not some old investor, nor I am new, but trying to understand this sector fucks my brain up.
