The Pacific Exchange (PCX): A historical overview

The Pacific Exchange, once a powerhouse in the financial world, emerged from the convergence of two 19th-century financial markets in California. The San Francisco Stock and Bond Exchange, established in 1882, aimed to facilitate financial trades linked to the abundant silver in the Comstock Lode of Nevada. Meanwhile, the Los Angeles Oil Exchange, led by oil tycoons, including Wallace Libby Hardison, opened in 1889.
These two exchanges merged in 1957, forming the Pacific Stock Exchange or PCX, a name later shortened to the Pacific Exchange in 1997. Throughout its illustrious history, the PCX played a crucial role in shaping San Francisco’s financial district, navigating events like the California Gold Rush and the Great Depression.

The PCX’s heyday and robust trading activity

For much of its history, the PCX thrived as a robust equity trading platform. By the mid-1980s, it became the nation’s third-largest options market, distinguishing itself as one of only four U.S. exchanges trading equity options. The exchange achieved another milestone by developing and implementing an electronic trading system, showcasing its innovative spirit.
During its peak, the PCX boasted trading floors in both Los Angeles and San Francisco, with the latter hosting two trading floors. In 1997, the exchange reached a pinnacle, trading over 2,700 stocks, bonds, and securities, with a record 3.3 billion shares changing hands.

Evolution and challenges: The PCX in the modern era

As the financial industry embraced automation in 1969, the PCX was among the pioneers to introduce computers for trading. However, with the advent of electronic trading, the PCX’s open outcry system became outdated. In response, PCX Holdings decided to demutualize in 1999, making it the first U.S. stock exchange to do so.
With the onset of the 21st century, the PCX faced significant changes. It sold its equity trading business to Archipelago in 2000, resulting in the closure of the Los Angeles trading floor in 2001 and the San Francisco Pine Street floor in the subsequent year. Archipelago Holdings Inc. completed its absorption of PCX in 2005, leading to the cessation of the Pacific Exchange as a standalone entity.

Legacy and the NYSE Arca era

In 2006, Archipelago merged with the New York Stock Exchange (NYSE), marking a new chapter for the PCX. Today, equity trading on the Pacific Exchange occurs exclusively through the NYSE Arca platform. However, the PCX’s options business continues to operate from its historic Montgomery Street headquarters in San Francisco.
Local firms like Casey Securities and major investors such as Goldman Sachs maintain a presence on the options floor, highlighting the enduring legacy of the PCX. The exchange’s journey, from a physical trading powerhouse to a digital entity, underscores the broader transformations in the financial industry driven by technological advancements.

PCX-Plus electronic options platform

In 2003, the Pacific Exchange introduced the PCX-Plus, an electronic options platform that allowed market-makers to execute trades either from the trading floor or remotely. This innovative platform exemplified the PCX’s commitment to staying at the forefront of electronic trading technology. Market-makers could seamlessly engage in options trading, showcasing the exchange’s adaptability to changing market dynamics.
Although the PCX-Plus became part of Archipelago’s operations after the acquisition, its legacy lives on in the broader context of electronic options trading.

Enduring legacy: PCX’s impact on local firms

While the PCX underwent a significant transformation in the early 2000s, its impact on local firms in San Francisco remains a noteworthy aspect of its legacy. Despite the closure of physical trading floors, local firms such as Casey Securities and Student Options continue to maintain a presence on the options floor.
This enduring legacy reflects the unique ecosystem that the PCX cultivated over the years. Major sell-side investors, including financial giants like Goldman Sachs, still engage in options trading through the NYSE Arca platform, further demonstrating the lasting influence of the PCX on the local financial landscape.

Casey Securities’ continued presence

Casey Securities, a local firm with historical ties to the PCX, has successfully transitioned into the electronic trading era. Maintaining a presence on the options floor, the firm exemplifies the adaptability of local businesses to evolving market conditions. This example underscores how the PCX’s legacy continues to shape the operations of firms deeply rooted in its history.

Goldman Sachs and NYSE Arca

Goldman Sachs, a prominent player in the financial industry, retains an active role in options trading through the NYSE Arca platform. The integration of major institutions like Goldman Sachs into the digital phase of the PCX highlights the exchange’s lasting impact on the broader financial community.

Conclusion

The Pacific Exchange’s journey, from a bustling physical exchange to a digital entity, mirrors broader trends in the financial industry. Its pioneering spirit in electronic trading, innovative platforms like PCX-Plus, and enduring impact on local firms showcase the exchange’s resilience amid significant changes.
While the PCX ceased to exist as an independent entity, its legacy lives on through the continued operation of its options business and the presence of key market players.
