In aggregate, Big Tech was worth $1.1 Tn at the end of 2012.
Over the last ten years (2013-2022), Big Tech collectively generated $2.3 Tn Operating Cash Flow (OCF), slightly more than double their aggregate market cap ten years ago!
To say it differently, Big Tech was a form of deep value investing that was deeply underappreciated even though they are all widely followed companies at that time!
