They were but it's not relevant - you need a frame of reference to compare the value lost/gained from. He's saying "Nvidia lost 40% of it's market" from what point in time? It's all time high ~$175B? Yeah sure I agree with that - but you can just as easily say Nvidia has gained significantly since 2015 when it was only $10B (now $90B). In the meantime AMD is down to $20B from $35B earlier in 2018 but he's not using that as the reference - he's using some other random point in time. He's just assigning arbitrary reference points so he can craft some weird narrative. What he's saying about Intel is just delusional. Per @alanm's link - even if Intel was to sell literally all it's current short-term assets and clear it's inventory it could only raise $30B in 2017. So either Intel somehow managed to increase that number by $60B unbeknownst to anyone or they've been hiding $60B overseas and will magically bring it back to the US for a buyout - actually according to him they have twice Nvidia so - $150B raised 2018/Hidden - which is also like half their marketcap lol. Intel just has half it's market cap in liquid assets apparently.
