Pisces isn’t the perfect solution to fixing the UK stock market’s problems

  • The FCA today confirmed in a joint statement with economic secretary to the Treasury, Emma Reynolds, that its Pisces private stock market will launch later this year
  • Government and the regulator expect Pisces to ‘strengthen UK capital markets’ and support economic growth as part of wider efforts to boost the economy
  • Pisces won’t be open to retail investors – unless they are employees of the company issuing the shares
  • Could act as a stepping stone for private companies towards an IPO on a public market
  • New stock market doesn’t sound the death knell for AIM
  • Pisces to be exempt from stamp duty but a shame the government didn’t do the same for all UK shares

“The proposed new stock market called ‘Pisces’ won’t be like the ones people know today. It’s just for privately-owned companies and while it won’t be open to the public, there are positives from its creation,” says Dan Coatsworth, investment analyst at AJ Bell.

“Pisces could help private companies get used to the idea of slices of their business being owned by different people. It might act as a stepping stone towards a public stock listing, getting them used to regular financial reporting, transparency as a business, and understanding that a company is run for the best interests of shareholders, not the board of directors.

“It could also encourage their staff to develop a saving and investing habit. One of the biggest stumbling blocks for private company share ownership is that staff are often put off by the general inability to sell those shares at regular intervals. A lot of private companies won’t offer the ability for staff to trade shares, meaning some people are stuck owning the equity until the business either lists on a public market or there is an internal event where they can sell down.

“In theory, Pisces could improve liquidity by allowing private company shares to be traded at more regular intervals. However, it has only been designed for intermittent trading, not the continuous trading during market hours that you get with publicly listed stocks. Such restrictions would give a company control over when changes in share ownership can happen.

“Disclosure requirements will be different to public markets in that investors taking part in a Pisces trading event should be told about company-specific information, but details won’t have to be made public. Lower levels of disclosure make Pisces-traded shares higher risk than ones available on London’s Main or AIM markets.”

What does Pisces mean for other markets and the economy?

“Pisces is not replacing an established stock market like AIM as it will not support capital raising and it won’t be open to the public.

“It is purely a secondary trading market and there will be restrictions on who can buy and sell. Apart from employees of the private company, only institutional investors, high net worth individuals or those deemed to be ‘sophisticated’ investors will be able to buy and sell via Pisces. Share buybacks will not be permitted, at least in the initial stages of the market’s life.

“These factors are important as they mean Pisces and AIM will not be direct rivals. The launch of Pisces does not sound the death knell for AIM. If anything, it could shine on a spotlight on AIM’s advantages in letting companies access capital markets for growth funding and the ability to conduct share buybacks, the latter treasured by many investors in the current environment. AIM is seen as a stepping stone for London’s Main Market – and now that journey could start earlier, with Pisces the stepping stone for AIM.

“Pisces won’t play an immediate role in the government’s plan to foster a culture of investing in the UK. However, anything that encourages more companies to think about broadening their investor base and potentially resulting in an IPO down the line is good for the future of the UK stock market.

“The government and the London Stock Exchange need all the help they can get to revive the UK stock market given the constant trickle of companies shifting their main listing to the US or being taken over. Time is running out to resolve this problem and Pisces could be a slow burner in terms of driving up volumes of companies seeking to get involved. We need a solution now, not later. Fundamentally, the UK stock market’s revival is dependent on larger firms choosing it as a venue to list their shares, not small ones.

“The proposal to make Pisces share transactions exempt from stamp duty and stamp duty reserve tax puts it in line with similar exemptions for AIM and the Aquis growth market. However, it’s a crying shame that the government hasn’t extended this status to all UK shares.

“The government is on a mission not only to encourage more people to invest in UK shares but also attract more investment from overseas. Removing stamp duty on all UK shares would be a major step forward as the current rules make the UK less competitive than many other locations such as the US and some European markets. Stamp duty is a cost for investors and can add up for those who place a lot of trades.

“Pisces is not going to change the world, but it should be a welcome addition to the UK’s investment ecosystem.”
