The old NASDAQ in 2000 cannot be compared to the new NASDAQ in 2015 because the companies in the index have changed, and the proportion of tech and health care companies has also changed. Healthcare and consumer companies are now 37% on the index compared to 18% in the NASDAQ index in 2000. Tech is a much smaller component of the NASDAQ, declining from 64% to 43%. And three companies Apple, Google and Microsoft, makeup 20% of the index, with Amazon, Facebook and Intel added making that 30% of the entire 2015 NASDAQ index. Only 3 of the top ten companies in the 2000 NASDAQ are around in 2015 NASDAQ index- Intel Corp., Microsoft, and Cisco Systems. Yahoo, Oracle, Dell, Sun, JDS, WorldCom are no longer the top 10 companies in the index as they were in 2015. The speculative momentum stocks such as Netflix and Tesla make up 0.38% and 0.33% of the NASDAQ in 2015. In healthcare part of NASDAQ 2015 companies such as Gilead Sciences and Amgen are in the top ten.
