The Society for Worldwide Interbank Financial Telecommunication (SWIFT) provides a secure communication network to financial institutions in order to communicate and facilitate cross-border transactions and payments.

The SWIFT system is a critical piece of infrastructure for the international banking system because it allows financial institutions to talk to one another securely. Without access to the SWIFT messaging network, banks are essentially shut out of the global financial system because they cannot speak to banks in other countries to agree to transaction and payment terms.

What Is SWIFT?

SWIFT doesn’t hold assets or move money around. Instead, it is a messaging system for banks and other financial institutions. When banks need to conduct business across borders with other financial companies, the SWIFT system allows them to communicate to one another in a secure and standardized manner to ensure reliable transaction terms.

The SWIFT messaging system relies on a standardized system of codes to transmit information and payment instructions. These codes are interchangeably called Bank Identifier Codes (BIC), SWIFT codes, SWIFT IDs, or ISO 9362 codes. Each member of the SWIFT network is assigned a BIC/SWIFT code, providing an efficient transfer of information during transactions.

The SWIFT codes are used so banks and financial institutions can communicate reliably. For example, a bank in the United States wants to make sure it is messaging the right bank in France to set up payment instructions before sending money.

Since SWIFT doesn’t send money, it requires banks to take additional steps to send money globally after communicating with their counterparty. This makes the whole process relatively slow and adds costs to the transfers. The advent of blockchain technology may alleviate these time lags and additional costs as the technology is adopted more broadly.

Format of BIC/SWIFT Code

These codes are unique and have 8 or 11 characters, identifying the bank, country, city, and branch.

•   Bank code (0-9 or A-Z): 4 characters representing the bank.

•   Country code (A-Z): 2 letters representing the country of the bank.

•   Location code (0-9 or A-Z): 2 characters of letters or numbers for the location of the bank.

•   Branch Code (0-9 or A-Z): 3 digits specifying a particular branch. This branch code is optional.

For example, Wells Fargo, with a branch in Philadelphia, has the 11-character SWIFT code PNBPUS33PHL. The first four characters reflect the institute code (PNBP for Wells Fargo), the next two are the country code (US), the following two characters specify the location/city code (33), and the last three characters indicate the individual branch (PHL). The last three characters are optional; if the bank is the head office, the code ends with XXX.

History of SWIFT

Telex was an early electronic communications system used in the post-World War II period, allowing businesses to send written messages across the globe. Before SWIFT, financial institutions used Telex to communicate with one another to ensure the successful transfer of international payments. However, Telex was slow, lacked security, and was prone to human error because it didn’t run on a standardized system.

To alleviate the problems of Telex, 239 banks from 15 countries joined forces in 1973 to develop a communications network that would provide safe, secure, and standardized messaging for cross-border payments. These banks formed the Society for Worldwide Interbank Financial Telecommunication and went live with the SWIFT messaging service in 1977. Soon, SWIFT was widely adopted and became the gold standard for cross-border messaging in the global financial system.

More than 11,000 financial institutions in over 200 countries use the SWIFT system to communicate. It processes tens of millions of messages per day, too. 

Who Controls SWIFT?

Based in Belgium, SWIFT is a member-owned cooperative, meaning that member institutions have stakes in SWIFT and the right to nominate directors to its governing board. This governing board is made up of 25 people from across the globe and overseen by the G-10 country central banks (Bank of Canada, Deutsche Bundesbank, European Central Bank, Banque de France, Banca d’Italia, Bank of Japan, De Nederlandsche Bank, Sveriges Riksbank, Swiss National Bank, Bank of England, USA Federal Reserve System), the European Central Bank, and the National Bank of Belgium.

Traditionally, SWIFT acts as a neutral party, so it doesn’t make any decisions on sanctions. However, because it operates under Belgian law and European Union regulations, SWIFT will adhere to sanctions imposed by the EU if necessary. This resulted in banks from Iran being kicked off the SWIFT system in 2012 because of the country’s nuclear weapon program. Additionally, in early 2022, several Russian institutions were kicked off of SWIFT after the country invaded Ukraine.

The Future of SWIFT

Because of SWIFT’s significant role in the global financial system, some believe that blockchain technology could circumvent the need to use the SWIFT network. Proponents of decentralized finance believe that these new technologies could increase global payments’ speed, security, and transparency. Just as SWIFT replaced Telex as the standard for messaging in the global financial system, some think that blockchain technology could do the same.

The Takeaway

SWIFT is a critical part of the global financial system. Without the secure messaging services of SWIFT, banks and other financial institutions would struggle to complete transactions and make payments in overseas business. However, the SWIFT system is relatively slow and costly for financial institutions. Even with the safe and secure messaging of SWIFT, cross-border payments and transfers between financial institutions can still take several days to complete. 

In a world that desires high-speed money transfers, this lag in transaction time can be burdensome to banks and other financial institutions. As new challengers in the global financial system, like blockchain technology, breakthrough and become a more mainstream part of the financial payments system, they could put pressure on the ubiquity of the SWIFT system and the overall global payments system.

What to know about how the New York Stock Exchange and Nasdaq work.

When a financial analyst rates a stock as overweight, it means that the analyst believes an overweight stock will likely outperform other stocks in its industry over the next six to 12 months. Conversely, if they describe a stock as underweight, they believe that it will perform poorly in the future.

It may be helpful to think of these terms as pointers: as if an industry specialist were saying, “You might want to overweight Stock X in your portfolio” or “maybe you should under-weight Stock Y.” These ratings are typically the result of factors in the news or pertaining to a specific company’s prospects. But the terms “overweight” and “underweight” also refer to a stock’s weighting in a relevant index or benchmark.

What Is an Overweight Stock?

As noted, an overweight stock is one that analysts believe will outperform others in its sector or market segment in the near future. Similarly, overweight stock is a moniker that may also describe a specific security’s weighting in a portfolio, and one that analysts think investors should buy more of – so, its meaning can be contextual in certain situations.

Types of Ratings and Where They Came From

To understand stock ratings related to weight, it’s important to know that market indexes assign a weight to the investments they track to be sure that the index accurately reflects the performance of that market sector.

For example, the S&P 500® tracks 500 large-cap U.S. companies. The companies in the index — called the constituents — are weighted by market capitalization. A company’s market cap is calculated by multiplying the current share price by the total number of outstanding shares.

Companies in that index are weighted based on the proportion of the overall index their market cap represents. Other indexes may use a different weighting system. The Dow Jones Industrial Average, for example, tracks 30 blue chip companies and weights them based on stock price. Companies with a higher share price are given more weight than those with lower prices.

Because of these different weighting systems, it’s important to understand that an overweight to a particular stock with regards to one index may not be the same when it comes to another.

Overweight Stocks

When an analyst rates Stock X as overweight, it’s generally a positive sign. First, they believe Stock X is likely to outperform its benchmark index, or even the market as a whole, depending on market conditions, so investors should consider holding more of the stock.

Bear in mind that an “overweight stock” rating doesn’t necessarily mean that stock is a juggernaut. In a down market, being overweight could simply mean the company might not lose as much ground as its peers, or it might grow less slowly than its peers.

Underweight Stocks

When an analyst rates Stock Y as underweight, the analyst believes that Stock Y is likely to underperform its benchmark, and investors should consider holding less of this stock.

Equal Weight Stocks

When an analyst gives an equal weight rating to a stock, that simply means it’s in line with the overall benchmark. Again, when considering these ratings it’s important to keep in mind the overall context of the market, and what these ratings mean to analysts.

Example of an Overweight Stock

A very simple example of an overweight stock could be when a stock, Stock X, is selling for $50, but experts and analysts think it’s undervalued and should trade for $75, it could be overweight.

Further, an overweight stock rating can be taken in two ways: First, that the stock will outperform its benchmark index and second that investors may want to take advantage of the increase in price.

When an analyst indicates their belief that a stock will appreciate, they may also state a potential time frame and price target for the stock. So, if Stock X is trading at $75 per share, and the company releases new earnings data that’s positive, an analyst might rate the stock as overweight, with a price target of $100 per share in the coming year.

The Downside of Weighting Stocks

One critique of this rating system is that no analyst, of course, can recommend how many shares investors should buy. It’s simply not possible for analysts to know whether Investor A’s portfolio might benefit from an additional 100 shares of Stock X, while Investor B might want to buy 1,000 shares of Stock X.

As a result, it’s incumbent on individual investor’s themselves to keep an eye on how relevant an overweight stock rating might be for their specific allocation. Buying more of Stock X could, in theory, create an imbalance and reduce a portfolio’s overall diversification. So while an overweight stock might be a good thing, an overweight portfolio usually is not.

How Can Investors Interpret Overweight Stocks?

At first glance, the terms overweight and underweight may seem more or less synonymous with “buy” and “sell” — in that case, why don’t analysts use these more straightforward terms?

In fact, the terms overweight and underweight do have a slightly different connotation than simply to buy or sell a security. Rather, the terms suggest a recommendation that a portfolio hold more or less of a particular position than an index or other benchmarks would suggest.

It may mean acquiring more, or selling some, of a particular investment. But it wouldn’t necessarily mean buying something new or selling all of a position. For example, if your portfolio has an allocation to tech stocks, and an analyst recommends overweighting one of those stocks, you may want to buy more of that company. Or you may not need more growth in your tech holdings, so you might look for an overweight stock.

Also, analysts aren’t always comfortable giving specific directions to buy or sell certain securities. The terms overweight and underweight are more like offering guidance: “Here’s what I think of Stock X or Stock Y. I’ll let the investor take it from here.”

In many cases an overweight or underweight recommendation might not be very useful for investors. For example, if an analyst recommends an overweight to a certain commodity but an investor’s portfolio doesn’t hold any commodities, this information may not have much bearing on their situation.

Can a Portfolio Be Considered Overweight?

Overweight can refer to a portfolio that holds more of a stock or other investments than it theoretically should. For individual investors, this might mean that more of a portfolio is allocated to stock than the investor intended.

For example, say an investor has a portfolio allocation in which 70% of its allocation is held in stock and 30% is held in bonds. If the stock market goes up, the proportion of the portfolio held in stock may grow beyond the 70% mark. At that point, the portfolio may be described as overweight in stocks, and an investor may want to rebalance to bring it in line with their initial allocation plan.

It may come as no surprise that the opposite of an overweight allocation is an underweight allocation. For example, if the stock allocation in the portfolio above fell below 70%, that allocation could be described as underweight in stocks.

The term can also apply in a narrower sense. For example, a stock portfolio could hold too much stock in one company, sector, or geographical region. In each case the holding could be described as overweight.

Professional fund managers may also use overweight to describe portfolios they work with that are off track with their index, including mutual funds, exchange-traded funds, and index funds. From time to time, a fund may get out of line with its benchmark index by holding more or less of an investment that index tracks.

For example, say an index fund is built to track the S&P 500. To track the index, fund managers will usually attempt to hold every stock in the index. Additionally, they will try to match the proportion of each individual company their fund holds to the index as well. So if stock A represents 5% of the original index, the fund will also hold 5% of stock A.

Some funds have a little bit of wiggle room in terms of how far they can stray from the index. Some might be allowed to hold more or less stocks if they think the stocks will outperform or underperform. When they hold more than the index, the managers are taking an overweight position. And when they hold less than the index, the managers are taking an underweight position.

The Takeaway

Overweight stocks are those that may be undervalued by the market. When an analyst gives a stock an overweight rating, broadly speaking it could be a good thing. If the analyst is correct, and the stock is indeed poised to perform better than its benchmark — maybe even better than the market as a whole — investors may want to buy that stock.

But the necessary caveat is that it all depends on context — the context of the market, and the context of an investor’s portfolio overall. You don’t want to buy a stock that could throw your allocation off, and make your portfolio overweight in a way that’s not ideal.

FAQ

Is overweight stock good?

An overweight stock can be good for investors looking for a relative deal, but it may not be a good thing if the investor already owns shares of the stock.

What is the difference between overweight and outperform stocks?

Outperform stocks and overweight stocks are similar, and the terms are often used interchangeably. But generally, “outperform” may describe a stock that’s undervalued or expected to offer solid returns in the future, but perhaps perform not quite as well as an “overweight” stock.

What is the difference between buy and overweight?

On an analysts’ rating system, “buy” and “overweight” stocks are rated differently, with “buy” being a higher rating – though both ratings are positive.
