This is a tough question. One that I unfortunately can't answer for you. But, I can provide some insight to maybe guide you or reinforce some of your thoughts, and then you can make a decision.
Personally, I do not invest in Facebook. I don't like the company. Not because it isn't a profitable well run business. But, just business practices and my general dislike of the platform and what it does to people makes me not invest. I didn't like what FB was doing long before this whistleblower situation. But, this just reinforces my own thoughts. I think the company is fueling a lot of what is wrong in the world today, and now they've been caught fueling fires as it creates more engagement.
I don't expect you to act based on my moral objection to investing in the company. I just thought I'd express it anyways.
Facebook will likely carry on from this and continue to be a profitable business. The company is looking to rebrand and be one of the first major players in the metaverse. But, I expect a lot of short term pressure on the share price because of what is going on right now.
From a valuation standpoint, it is pretty cheap. It's likely all of the commotion going on with the company right now is causing depressed valuations and as such on the surface, if we analyze strictly the company and its growth and reliability, is very cheap. But, there is some deep rooted issues with Facebook, some that have now become public. And how it will impact the company moving forward is impossible to tell.
