Sip, I've heard it all before... look at the 30-year chart of CSCO... great company... was the shit back in the late 90's... the internet was going to change everything and CSCO would be at the center of it all, topped in March 2000 at $146 and has never reached the highs since, now trading at $50. The internet was world changing, but that didn't mean CSCO was the winner...
I say that with NVDA and other semiconductor manufactures in mind... this is the top of the market for the chip manufactures... demand and margins will never be higher, new manufactures & competition will now eat into prices... the current share prices will not be supported by earnings, I suspect they will also be looking back for the next 20 years to see their highs...
