This note considers Initial Public Offerings (IPOs), particularly in relation to the 1990s dotcom bubble.

It covers -

It supplements the discussion of innovation capital, the 'new economy' and the bubble elsewhere on this site.

subsection heading icon     introduction

Initial Public Offerings (IPOs) involve offering shares to the public for the first time, usually with a prospectus that details the investment offer. IPOs are often described as flotation, going public or listing. Prior to an IPO enterprises that sell shares to investors are considered to be privately held. The IPO allows investors to liquidate some or all of their interest in the particular entity when it becomes a public company.

In 1999 there were 457 IPOs on the NYSE, NASDAQ and AMEX in the US, most of which were technology and internet related. 117 doubled in price on the first day of trading. Two years later the number of IPOs in the US was a mere 78; none of them doubled during the first day's trading. In 2004 there were 260 IPOs in the US, raising US$51 billion. That compared to 88 IPOs in 2003 (for US$18.6 billion). The ten largest US IPOs in 2004 (including Genworth Financial at US$2.8 billion, Chinese Semiconductor Manufacturing at US$1.8 billion, Assurant at US$1.76 billion and Google at $1.7 billion) accounted for 30% of overall IPO proceeds in 2004, compared with 48% in 2003.

subsection heading icon     dotcom fever

The popular image of IPOs is the opportunity for 'stags' to make large initial returns when to stock lists, typically through increases in value of 15% to 20% from offering price to the market price at the end of the first trading day). In the US the mean initial return is about 15 percent. That phenomenon - often referred to as 'new issue underpricing' - is evident in every nation with a stock market, although the amount of underpricing varies from nation to nation.

The dotcom bubble saw start-ups - few of which had made money (and many of which appear in retrospect unlikely to have ever made money) - gain huge market capitalisations when listed through an IPO. Examples include Globe.com, which on the first day of trading went from US$9 to US$97 per share (an increase of 866%), Value America from US$23 to US$74.25 per share, VA Linux from US$30 to US$238 in its first day, Akamai Technologies from US$26 to US$145, Marketwatch.com from US$17 to US$97 and Webmethods from US$35 to US$212.

Prior to 1983 publicly held firms in the US traditionally began trading on the NASDAQ or regional markets before moving to the NYSE. In 1983 the NYSE changed its listing rules in 1983, making initial listing on that exchange a viable alternative for some large IPOs. The NYSE minimum listing requirements remained the same as for other firms, but the exchange allowed the underwriter to certify that the IPO would meet share ownership and distribution standards. The initial listing decision then became an important part of the IPO process, with the number of IPOs listed directly on the NYSE increasing from 2.5% in 1983 to over 30% in 1989.

Shane Corwin & Jeffrey Harris's 2001 paper The Initial Listing Decisions of Firms That Go Public considered the initial listing decisions of IPOs that qualify for NYSE listing, concluding that US IPOs are more likely to list on the exchange that features their industry peers and that (consistent with avoidance of delisting costs) smaller - riskier - firms tend to list on Nasdaq. the that the NYSE firms for listing. From 1981 to 1990 the NYSE had a net gain of only 204 listed companies but after it began to aggressively target IPOs in the early 1990s the number of NYSE-listed firms increased by 1,133, from 1991 through 1996, including over 700 IPOs.
