Mark Hulbert points to the comparison of financial ratios in Dec 1999 when the Nasdaq Composite Index reached 4000, with the situation in November 2013 when the Index again crossed 4000. He cites the changes from P/E ratios for trailing earnings at 30 in 1999 compared to 20 in 2013 for the Nasdaq Index, Shiller cyclically adjusted P/E ratios at 44 in 1999 compared 24 in 2013, Price/Book ratios at 5.1 in 1999 compared to 2.6 in 2013, and Price to Sales ratios at 2.4 in 1999 compared to 1.6 in 2013. The broad market could still be overvalued says Hulbert, but the Nasdaq index shows tech companies not speculatively driven up in the way they were in 1999.
