While investors may have a desire to own stocks as quickly as they come to market, a reasonable concern is whether that’s appropriate for a long-term investment strategy. “For many individuals, it makes sense to give these stocks time before investing,” says Amin. He notes that once a stock goes public, there’s a 180-day lockup period that restricts private investors in the company from selling shares. “Once that lockup period expires, you’ll have a better sense of private investors’ sentiment about the company’s outlook,” says Amin. If many private investors put their shares on the market when the lockup period expires, it may reflect a lack of confidence in the company’s future prospects. If instead more of those investors hold onto their stock, it may indicate their expectation of future share price appreciation. That would be a positive sign to other investors.
Haworth points out that companies from all industry sectors go public, with no discernible trend indicating which tend to perform best over time. “It’s really a company-by-company situation,” says Haworth. “Certain environments may favor certain types of stocks, but there’s no particular advantage a specific industry has demonstrated over time.”
Recent IPO performance
Based on at least one recognized measure, IPO performance has fluctuated over time. An exchange-traded fund (ETF) known as the Renaissance IPO ETF, invests in newly issued stock. The fund holds IPO issues for no more than three years after they go public.
The fund’s share price gained 34% in 2019 and 108% in 2020, before experiencing declines of 10% in 2021 and 57% in 2022. The fund rebounded in 2023. Through September 26, its share price was up more than 25% for the year.2

The performance of individual IPO issues will vary widely with the results of the Renaissance ETF fund. To demonstrate the potential volatility of new IPOs, consider the experience of Arm Holdings in the first days after its IPO. When Arm’s stock went public on September 14 priced at $51/share, its price jumped to more than $65/share during the next trading day. However, by September 21, the price was below its initial offering price of $51/share. It since recovered modestly, but far from its peak price of the first two days of trading.2 It reflects the unpredictable, short-term nature of new issue pricing. Haworth notes that the day an IPO first hits the market “is often the peak of enthusiasm for the stock, and the environment often becomes more challenging thereafter.”
A longer-term trend common with IPOs, adds Amin, “is that we see newly issued stocks rise faster than the broader market in a bull market, but also potentially decline more rapidly than stocks as a whole in a declining market.”
Assessing the IPO market’s role in your portfolio
IPOs offer a combination of opportunities and challenges. Some companies that demonstrate an ability to grow consistently over time may generate favorable returns for investors who are able to take advantage of the new issuance of stock. That is the goal many investors have in mind when they invest in new issues. However, that scenario doesn’t always play out.
“One challenge for investors with an interest in IPOs is that they have to try to do research on a company that’s been privately held,” says Haworth. “Without the kind of readily available information that must be disclosed by public companies, it can be difficult to discern the quality and value of the stock.” Haworth urges investors to carefully assess how any IPO investment might fit in with their overall portfolio strategy.
Amin reiterates the importance of exercising patience before investing in IPOs. “The early days of trading can be very speculative. The real value becomes more apparent six months after the initial offering,” says Amin. “You want to be sure the firm has a track record of profitability and a path toward future growth as you evaluate the merits of an individual stock for your portfolio.”
Because of their limited track record, IPOs can be more speculative than established stocks. Before investing, talk with your wealth professional about how new issues in the IPO market may benefit your long-term investment strategy.
Note: The implied volatility and speculative nature of initial public offerings may make IPOs better suited for investors with longer term time horizons who can bear a substantial loss of principal.
