Why IPOs are best avoided

Footasylum: not a great advert for going public

In an IPO (initial public offering), the odds are stacked against you. The seller has more knowledge than you do. So why bother?

In November last year, sportswear chain Footasylum made its stockmarket debut at a share price of £1.64. On the day of its initial public offering (IPO – defined here) the price surged by more than 20%. The firm had a solid pedigree – it has been around since 2005 and was set up by the founders of JD Sports, a successful business in the same sector. Yet this week, following its second big profit warning in four months, the share price sits at below 40p, after shedding more than 50% on Monday alone, when the firm warned that profits would be well below the £12.5m it made last year.

It’s an illustration of just how badly wrong things can go when you invest in an IPO. Yet while Footasylum is a particularly dramatic example, it’s hardly alone. Many studies have shown that, in the long run (over five years and beyond), a strategy of buying stocks at an IPO underperforms tracking the wider market. Academic economists spend a lot of time agonising over why this is – an efficient market shouldn’t consistently get IPO prices so wrong – but common sense explains why.

Investing in an IPO is just like investing in any other listed company, save for two crucial differences. Firstly, information is harder to come by for an IPO because of the lack of public trading history. Secondly, the insiders who know the company best have chosen this particular moment to sell. They may well be hanging on to a stake (Footasylum’s founders did), but the point still holds – the seller believes that now is a good opportunity to get a good price for their company. Meanwhile, everyone else involved in the process – such as the investment bankers making big fees off the deal – are highly motivated to make the sale succeed. In short, the cards are stacked in favour of the seller in a way they are not for a company that has already been exposed to the public scrutiny of the stockmarket.

Of course, not all IPOs do badly. The MoneyWeek team is still kicking itself for its negative view of the IPO of internet giant Google (now Alphabet) at the princely sum of $85 a share (now about $1,200), back in 2004. Even so, Google didn’t become a 14-bagger overnight – you didn’t have to invest at the IPO to do well.

And as an investor, I’m in favour of keeping things simple. Successful, thoughtful investing in individual stocks is time consuming. It requires detailed research and analysis. So if you are willing to do all the hard work involved in tracking down a promising company, and you are confident of your ability to do so, then why – of all the options already available on the stock exchange – would you choose to spend that time analysing an IPO?
