A way of gauging the extent of a bubble in the internet IPO's in 2013, says Hulbert, is the first day return on IPO's in the U.S. of 25% in mid-Aug to mid-Nov 2013 compared to 96% in the first quarter of 2000. He cites a study by finance professors Jerry Wurgler of New York University's Stern School of Business and Malcolm Baker of Harvard Business School, which stresses the need to use objective indicators in assessing the current equity markets and not relying on memories alone. Investor caution after two bubbles since 2000, active regulatory oversight of markets, and legal frameworks updated for changes in financial markets have provided additional safety and stability to markets. The study authors cite evidence for the changes in the way investor sentiment values speculative stocks compared to established stocks. The price/book ratio per share or net worth of established stocks is way higher compared to speculative stocks in 2013 compared to 2000. In 2013 established companies in the S&P 1500 index, according to FactSet, had a 49% higher price/book ratio on average than speculative stocks. Wurgler and Baker used dividend paying stocks as "established" stocks compared to non dividend paying stocks as "speculative." Another piece of evidence that companies are also adjusting to sentiment this time is that less money is coming from stock issuance in 2013 of 11% compared to 20% in 2000. Visible evidence of company behaviour is also telling- banks are changing bahaviour after tougher regulatory oversight and settlements in 2013. GE is planning to shrink GE Capital and put it on sale. Investors have sharply cut back allocations to stocks and are returning to modestly higher allocations from much lower levels and memories of 2000 and 2008 are still present....
