Yes, he bought like 3MM NFLX shares on the dip for about $1BB position. And he promptly announced it on Twitter. AND he made his position known. Expecting others to follow him. Market manipulation. He is a master of it. When Bill Ackman was fighting Herbalife HLF, he even paid some HLF former employees to do TV interviews to trash HLF. Then Carl Icahn took the long side and crushed Bill Ackman. To the end, Bill Ackman gave up. His loss was $1BB and Car's gain was $1BB. Without Carl Icahn, Herbalife would have been crushed and Bill would go with probably $1BB gain.... Not sure if this is "smart", or market manipulation.
Carl Icahn (who went to same HS as I did FRHS, Queens, NY) made Ackman look not so smart gamma squeezing him on HLF, without any help from WSB - just his billions. But an AUM of $13 billion plus says Ack is far smarter than any of US. Now as for Icahn no one out talks him when it comes to their book.
I do not have the thick skin to get on TV to announce my HLF fraud theory. Or the legal resources to manipulate stock market. I like fund managers with really good skills to pick stocks. But not as stubborn as Cathie Wood is. She is another market manipulator. Most HF managers are like Jim Simons, who keeps a very low profile and does not talk about his stocks. He kept a black box.
