What Is the 48-Hour Rule?

The 48-hour rule is a requirement that sellers of to-be-announced (TBA) mortgage-backed securities (MBS) communicate all pool information regarding the MBS to buyers before 3 p.m. Eastern Time, 48 hours before the settlement date of the trade. The Securities Industry and Financial Markets Association (SIFMA) enforces this rule. SIFMA was formerly known as the Public Securities Association or Bond Market Association.

Understanding the 48-Hour Rule

An MBS is a bond that is secured, or backed, by mortgage loans. Loans with similar traits are grouped to form a pool. The pool is then sold as a security to investors. The issuance of interest and principal payments to investors is at a rate based on the principal and interest payments made by the borrowers of the underlying mortgages. Investors receive interest payments monthly rather than semiannually.

A to-be-announced (TBA) trade is effectively a contract to buy or sell mortgage-backed securities (MBS) on a specific date. It does not include information regarding the pool number, the number of pools, or the exact amount involved in the transaction, which means the underlying mortgages are not known to the parties. This exclusion of data is due to the TBA market assuming that MBS pools are more or less interchangeable. This interchangeability helps facilitate trading and liquidity.

The 48-hour rule is part of the mortgage allocation process, the period when the underlying mortgages will be assigned and made available to a specific MBS, which was created to bring transparency to TBA trade settlements.

The 48-hour rule states that the seller of a specific MBS must make the buyer of that MBS aware of the mortgages that make up the MBS 48 hours prior to the trade settling. Because of the standard T+3 settlement date, this usually occurs on the day after the trade is executed.

The 48-Hour Rule as Part of the TBA Process

The TBA process benefits buyers and sellers because it increases the liquidity of the MBS market by taking thousands of different mortgage-backed securities with different characteristics and trading them through a handful of contracts.

Buyers and sellers of TBA trades agree on a few necessary parameters such as issuer maturity, coupon, price, par amount, and settlement date. The specific securities involved in the trade are announced 48 hours before the settlement.

The TBA market was established in the 1970s to facilitate the trading of MBS issued by Fannie Mae, Freddie Mac, and Ginnie Mae. It allows mortgage lenders to hedge their origination pipelines.

The TBA market is the most liquid secondary market for mortgage loans, resulting in high levels of market activity. In fact, the amount of money traded on the TBA market is second only to the U.S. Treasury market.

Example of the 48-Hour Rule

Company ABC decides to sell a mortgage-backed security (MBS) to Company XYZ and Company XYZ accepts. The sale will take place on Tuesday. On Tuesday, when the sale is made, neither Company ABC nor Company XYZ knows the underlying mortgages that make up the mortgage-backed security (MBS).

The standard industry settlement is T+3 days, meaning this trade will settle on Friday. According to the 48-hour rule, on Wednesday before 3 p.m. Eastern Time, Company ABC will have to notify Company XYZ of the mortgage allocations it will receive when the trade settles.

What Is the 52-Week Range?

The 52-week range is a data point traditionally reported by printed financial news media, but more modernly included in data feeds from financial information sources online. The data point includes the lowest and highest price at which a stock has traded during the previous 52 weeks.

Investors use this information as a proxy for how much fluctuation and risk they may have to endure over the course of a year should they choose to invest in a given stock. Investors can find a stock’s 52-week range in a stock’s quote summary provided by a broker or financial information website. The visual representation of this data can be observed on a price chart that displays one year’s worth of price data.

Understanding the 52-Week Range

The 52-week range can be a single data point of two numbers: the highest and lowest price for the previous year. But there is much more to the story than these two numbers alone. Visualizing the data in a chart to show the price action for the entire year can provide a much better context for how these numbers are generated.

Since price movement is not always balanced and rarely symmetrical, it is important for an investor to know which number was more recent, the high or the low. Usually an investor will assume the number closest to the current price is the most recent one, but this is not always the case, and not knowing the correct information can make for costly investment decisions.

Two examples of the 52-week range in the following chart show how useful it might be to compare the high and low prices with the larger picture of the price data over the past year.

These examples show virtually the same high and low data points for a 52-week range (set 1 marked in blue lines) and a trend that seems to indicate a short-term downward move ahead.

The overlapping range on the same stock (set 2 marked in red lines) now seems to imply that an upward move may be following at least in the short term. Both of these trends can be seen to play out as expected (though such outcomes are never certain). Technical analysts compare a stock’s current trading price and its recent trend to its 52-week range to get a broad sense of how the stock is performing relative to the past 12 months. They also look to see how much the stock’s price has fluctuated, and whether such fluctuation is likely to continue or even increase.

The information from the high and low data points may indicate the potential future range of the stock and how volatile its price is, but only the trend and relative strength studies can help a trader or analyst understand the context of those two data points. Most financial websites that quote a stock’s share price also quote its 52-week range. Sites like Yahoo Finance, Finviz.com and StockCharts.com allow investors to scan for stocks trading at their 12-month high or low.

Current Price Relative to 52-Week Range

To calculate where a stock is currently trading at in relations to its 52-week high and low, consider the following example:

Suppose over the last year that a stock has traded as high as $100, as low as $50 and is currently trading at $70. This means the stock is trading 30% below its 52-week high (1-(70/100) = 0.30 or 30%) and 40% above its 52-week low ((70/50) – 1 = 0.40 or 40%). These calculations take the difference between the current price and the high or low price over the past 12 months and then convert them to percentages.

52-Week Range Trading Strategies

Investors can use a breakout strategy and buy a stock when it trades above its 52-week range, or open a short position when it trades below it. Aggressive traders could place a stop-limit order slightly above or below the 52-week trade to catch the initial breakout. Price often retraces back to the breakout level before resuming its trend; therefore, traders who want to take a more conservative approach may want to wait for a retracement before entering the market to avoid chasing the breakout.

Volume should be steadily increasing when a stock’s price nears the high or low of its 12-month range to show the issue has enough participation to break out to a new level. Trades could use indicators like the on-balance volume (OBV) to track rising volume. The breakout should ideally trade above or below a psychological number also, such as $50 or $100, to help gain the attention of institutional investors.

What Is an Application Programming Interface (API)?

An application programming interface (API) is a set of programming codes that queries data, parse responses, and sends instructions between one software platform and another. APIs are used extensively in providing data services across a range of fields and contexts.

APIs have become increasingly popular tools, with the likes of Meta (formerly Facebook), Amazon, SalesForce, and many more establishing their own APIs that allow companies to access some of their services without having to fully migrate into their ecosystem. This new paradigm has led to the rise of what some experts call the “API economy,” a model that enhances a company’s bottom line by improving interoperability and thus creating new systems from existing ones.

In the domain of financial markets and trading, one may use an API to establish a connection between a set of automated trading algorithms and the trader’s preferred trading broker platform for the purpose of obtaining real-time quotes and pricing data or to place electronic trades.

Understanding Application Programming Interfaces (APIs)

APIs have become increasingly popular with the rise of automated trading systems. In the past, retail traders were forced to screen for opportunities in one application and separately place trades with their broker. Many retail brokers now provide APIs that enable traders to directly connect their screening software with the brokerage account to share real-time prices and place orders. Traders can even develop their own applications using programming languages like Python and execute trades using a broker’s API.

Two types of traders use broker APIs:

• Third-Party Applications – Many traders use third-party applications that require access to broker APIs for pricing data and placing trades. For example, MetaTrader is one of the most popular foreign exchange (forex) trading applications and requires API access to secure real-time pricing and place trades.
• Developer Applications – A growing number of traders develop their own automated trading systems, using programming languages like Python, and require a way to access pricing data and place trades.

Despite the apparent benefits of APIs, there are many risks to consider. Most APIs are provided to a broker’s customers free of charge, but there are some cases where traders may incur an extra fee. It’s important to understand these fees before using the API.

Traders should also be aware of any API limitations, including the potential for downtime, which could significantly affect trading results.

Where to Find APIs for Traders

The most popular brokers supporting API access in the traditional stock and futures markets include TradeStation, TDAmeritrade, and InteractiveBrokers, but many smaller brokers have expanded access over time. APIs are more common among forex brokers where third-party applications and trading systems—such as MetaTrader—have been commonly used for many years.

Many brokers provide online documentation for their APIs. Developers can find out exactly how to authenticate with the API, what data is available for consumption, how to place orders through the API, and other technical details. It’s essential to be familiar with these details before choosing a broker when looking for specific functionality.

Some brokers also provide libraries in various languages to make interaction with their API easier. For example, a broker may offer a Python library that provides a set of functions, or methods, for placing a trade rather than having to write your own functions to do so. This can help accelerate the development of trading systems and make them less costly to develop.

What Is an Anti-Dumping Duty?

An anti-dumping duty is a protectionist tariff that a domestic government imposes on foreign imports that it believes are priced below fair market value. Dumping is a process wherein a company exports a product at a price that is significantly lower than the price it normally charges in its home (or its domestic) market.

In order to protect their respective economy, many countries impose duties on products they believe are being dumped in their national market because these products have the potential to undercut local businesses and the local economy.

Understanding Anti-Dumping Duties

In the U.S., the International Trade Commission (ITC)–an independent government agency–is tasked with imposing anti-dumping duties. Their actions are based on recommendations they receive from the U.S. Department of Commerce and investigations by the ITC and/or the Department of Commerce. 

In many cases, the duties imposed on these goods exceeds the value of the goods. Anti-dumping duties are typically levied when a foreign company is selling an item significantly below the price at which it is being produced.

While the intention of anti-dumping duties is to save domestic jobs, these tariffs can also lead to higher prices for domestic consumers. And, in the long-term, anti-dumping duties can reduce the international competition of domestic companies producing similar goods.

The World Trade Organization (WTO) is an international organization that deals with the rules of trade between nations. The WTO also operates a set of international trade rules, including the international regulation of anti-dumping measures. The WTO does not intervene in the activities of companies engaged in dumping. Instead, it focuses on how governments can—or cannot—react to the practice of dumping. In general, the WTO agreement permits governments to act against dumping “if it causes or threatens material injury to an established industry in the territory of a contracting party or materially retards the establishment of a domestic industry.”

This intervention must be justified in order to uphold the WTO’s commitment to free-market principles. Anti-dumping duties have the potential to distort the market. In a free market, governments cannot normally determine what constitutes a fair market price for any good or service.

Example of an Anti-Dumping Duty

In June 2015, American steel companies United States Steel Corp., Nucor Corp., Steel Dynamics Inc., ArcelorMittal USA, AK Steel Corp., and California Steel Industries, Inc. filed a complaint with the U.S. Department of Commerce and the ITC. Their complaint alleged that several countries, including China, were dumping steel into the U.S. market and keeping prices unfairly low.

After conducting a review, one year later the U.S. announced that it would be imposing a total of 522% combined anti-dumping and countervailing import duties on certain steel imported from China. In 2018, China filed a complaint with the WTO challenging the tariffs imposed by the Trump administration. Since then, the Trump administration has continued to use the WTO to challenge what it claims are unfair trading practices by the Chinese government and other trading partners.
