This final note on the way out today: This week’s sign of the apocalypse.

You may have heard of ETFs — exchange traded funds. 

Bloomberg is reporting that there’s an ETF in the works that’ll trade on social media sentiment. 

Not social media stocks mind you, but companies that are being talked about on social media.

The fund will reportedly hold the 25 most-tweeted-about stocks and use an algorithm to decide whether to buy or short a specific company based on what people are tweeting.

How could that possibly go wrong?
