Retail investors have driven much of AMC Entertainment’s stock roller coaster, and they’re calling themselves “apes.” One of the most vocal of those apes: host of YouTube channel “Trey’s Trades,” Trey Collins. Just hours after his YouTube interview with AMC CEO Adam Aron, Collins shared his outlook for AMC stock and the meme stock movement. He believes the fundamental value of the movie theater chain’s shares will be between $20 and $25 at the end of 2021, although shares of the company hit an all-time high this week, topping out at $72.62. Squawk Box anchors Joe Kernen, Becky Quick and Andrew Ross Sorkin go inside the general shift happening in the stock markets -- it’s about more than free popcorn.
