Trading Restrictions Explained: What, When and Why

Trading Restrictions Explained: What, When and Why

‍

Sometimes trading in an investment can be suspended or limited. This can happen for a number of reasons, including a decision by Quilter Invest, corporate actions, or regulatory or legal requirements.

The specific details of each event will vary each time, and the actions available to you will depend on the restriction in place.

1. A decision by Quilter Invest

In some circumstances, Quilter Invest may decide to stop allowing further purchases of an investment on our platform. This does not necessarily mean there is anything wrong with the investment itself. Any restriction applied by Quilter Invest relates to availability on our platform and does not necessarily reflect the underlying quality or prospects of the investment.

For example, we may make this decision following a review of the investments available through Quilter Invest.

When this happens, an investment may be placed into liquidation only status. This means you can continue to hold your investment or sell your existing holdings, but you won't be able to make any new purchases.

Unlike a full trading suspension, where buying and selling may both be restricted, liquidation only status still allows existing investors to decide whether to continue holding their investment or sell it.

The actions available to investors will depend on the specific circumstances of the restriction. These restrictions may be temporary or permanent. Where restrictions are lifted, purchases may become available again in the future.

2. Corporate actions

Corporate actions might sound like industry jargon, but they’re actually very important for investors. Corporate actions can bring changes that affect shareholders and may influence a company's share price. Think about them as major milestones that may affect shareholders and can alter how a company's shares are traded or valued.

Whether they’re voluntary, when investors choose to participate, or mandatory, when participation is compulsory, corporate actions are essential for investors to understand. Let’s dive in.

Common examples of corporate actions include:
Stock Splits and Reverse Splits: Adjusting the number of shares you own and their price proportionally
Dividends: Payments made to shareholders from a company's profits
Name or Trading Symbol Changes: Changing a company's identity in the market
Mergers and Acquisitions: When companies combine or one buys another
Spinoffs: Creating a new independent company from part of an existing one
Rights Issues: Offering additional shares to existing shareholders
Liquidation: Closing down the company and distributing its assets to shareholders

While companies and exchanges strive to notify investors of upcoming corporate actions, it’s not always possible. But as soon as we can, we’ll let you know. The specific details of each event will vary each time, and sometimes corporate actions can mean trading in the company’s stock is suspended or limited.

3. Regulatory or legal reasons

So, what exactly happens when trading is suspended? Essentially, it’s when the ability to buy and sell a security is halted. This can happen when there are serious concerns about a company’s assets, operations, or other financial matters.

Events such as trading suspensions can highlight some of the risks associated with investing. Whilst it can be rewarding, investing is also unpredictable and is influenced by factors beyond our control.

Several factors can trigger trading suspension, including:

  • If a company isn’t keeping up with its financial reporting
  • Concerns about the accuracy of public information, like unreliable information or press releases
  • Issues related to insider trading or market manipulation

However, such events can also happen even without underlying financial problems. For example, in 2018 the NYSE suspended trading in some Nasdaq-listed shares, including popular names like Alphabet (GOOG) and Amazon (AMZN), due to a technical glitch. This temporary suspension was resolved within a day, showing that such events can happen even without underlying financial problems.

Trading suspensions are generally intended to help maintain orderly markets and protect investors where there are concerns about trading or available information.

What Happens During Suspended Trading?

‍

When the SEC (Securities and Exchange Commission) suspends trading, they issue a press release explaining the reasons, and refrain from further comments to prevent an unfair negative impact on existing investors. The suspension can last up to 10 days, but sometimes it’s resolved much quicker. The length of a suspension depends on the circumstances and the authority imposing it.

In the UK, the decision is typically made by the Financial Conduct Authority (FCA) in coordination with the LSE. In the UK, trading restrictions may be imposed by a regulator, exchange, or trading venue depending on the circumstances. The decision is publicly announced, including details of the asset affected, the reason, and any relevant instructions or timelines. And then trading is immediately halted whilst an investigation occurs.

If the suspension is lifted, trading may resume, although the arrangements will depend on the circumstances
‍

Impacts of Suspended Trading

Trading suspensions can result in increased volatility or significant price movements when trading resumes. Companies typically work quickly to address the concerns that led to the suspension by submitting required financial statements and information.

If you bought or sold an asset before a corporate event, but it’s not due to settle until afterward, you don’t need to worry. Orders are binding contracts from the point of execution, so if you completed a transaction before trading was suspended, you’ll still receive your shares or your money.

Always remember, when investing the value of investments can go down as well and up, and you may get back less than you invest. You should always be aware of the risks, and the potential that you could lose more than you invest.
