I think this is a very fun idea for a piece of content, but it's important to add context when talking about how mutual funds value private companies, specifically regarding markdowns. I highly recommend anyone interested read this:

"While these markdowns have caused a big reaction from much of the media, the valuation write-offs aren't as overly indicative of an actual decline in the performance of these privately held companies—rather simply an accounting measure these funds have to abide by. Sure, some of these companies likely have their own business issues but the story is a bit overblown, so let's provide some context."
