He was just on CNBC
I don't remember him giving a specific time period. They will probably offer this video clip on their website. He basically said that the current decline is precisely similar to the past one and considers this to be a buying opportunity.
Thanks. Added more shares today at 582 and also bought the Jan 580 call. I hope this makes a big move back over 600 soon. Never seen a stock this oversold and cheap before. it's ridiculous. yet, amzn trades over 200 p/e .
