What is Python?
Python is an object-oriented programming language that includes built-in data structures and dynamic typing and binding. Its straightforward syntax is considered to be readable and easy to learn. Many programmers are drawn to Python because of the increased productivity it affords. Python doesn’t require a compilation step and its edit-test-debug cycle runs very quickly, which makes it easy to debug.
Python for Hedge Funds
The face of trading has changed significantly over the years. Long gone are the days of pit traders’ open outcry. Now, instead of shouting and signaling on the trading floors of the stock exchange, the floors are now a spot for virtual exchange, and most of the traders have been substituted with algorithms. Automation has eliminated the need for quick computations on the fly. Now, the majority of market making in asset classes is fully automated. There is less of a need for traders now, and those who remain often have a background in writing code.
The investment pools in hedge funds are handled by managers who use a variety of strategies, such as trading esoteric assets as well as buying with borrowed money, to come out ahead of average investment returns. It’s the job of a Hedge Fund Manager to look for securities with the potential to bring in outsized returns. In the event that this strategy isn’t successful, they try to find a hedge. Because they require a significant minimum investment, and because they are considered to be a risky investment choice, hedge funds are typically only available to wealthy clients.
Looking specifically at the buy-side of the stock market, traders typically fall into three categories: Quantitative Strategy Traders, Execution Traders, and High-Frequency Traders:
- Quantitative Strategy Traders are the ones tasked with creating quantitative strategies that draw from computer models to trade systematically. These traders rely on coding skills to help them sort through huge amounts of data so that they can design prototype strategies aimed at testing ideas. Many Quantitative Strategy Traders prefer using Python because it has many data analysis packages available, such as Pandas, R, and SciPy.
- Execution Traders working on the buy-side are the ones who implement the portfolio decisions driven by Portfolio Managers or quantitative strategies. To do so, they either outsource banks’ third-party execution algorithms, create their own algorithms, or manually trade. Knowing how to create unique algorithms requires coding skills.
- High-Frequency Traders perform similar tasks to Quantitative Strategy traders but have a much smaller time window to complete actions. They often use Python, as well as the Hadoop ecosystem, to inform their trades. While C++ performs quicker than Python in most instances, High-Frequence Traders often prefer Python because of its versatility.
Data science tools such as Python provide a valuable tool for managing hedge funds. Here are some of the ways this language can be used to identify potential trade opportunities:
- Spotting opportunities. There are tens of thousands of instruments currently available for publicly traded equity. The sheer number of options makes it impossible for Analysts working with hedge funds to sort through every instrument to single in on an opportunity. With the help of Python, scripts can be written that will scan the financial options in just minutes. Python integration is often a central component of trading platforms that hedge funds. This language’s applications and custom functions perform well in a trading platform. Python also makes it possible to customize scanning so that it fits the needs of the firm. In addition, many Python screening functions can be fully automated.
- Backtesting & real-time testing. Before hedge fund money is invested, it’s prudent to test the effectiveness of the hypothesis on which it is based. One way to do so is with an algorithm that draws from historical data. These backtests provide insights into whether a strategy is sound, as well as how it can be improved. Once multiple tests have been run, the strategy can then be tested on live data. That’s where Python comes in. Python scripts can virtually implement a strategy using real-time data.
- Executing trades. After a strategy has been tested multiple times, revised, and finalized, it can be used to execute trades. Most exchanges allow API-based trades, which means trading bots can perform trades algorithmically. The automated bot can be customized to include risk parameters, stop-loss features, as well as strategies to handle different scenarios. These sorts of trade executions are hands-free, which allows Analysts to focus their time and efforts on the continued process of building sound strategies and higher-order concerns. In fact, most hedge funds don’t even employ full-time traders and instead use trading platforms based on algorithmic trading. After positive results have been found from backtesting and real-time testing, the strategy can then be codified as a Python trading bot, which will perform trades without the need for any human involvement.
While C++ is still used in hedge fund situations in which low latency and high performance are needed, and Java also remains a popular option, Python is considered to be the preferred language for hedge fund trading. It provides a vital tool for data collection and storage and can form a bridge between technology and research. With an increased reliance on data science tools like Python, Hedge Fund Managers and Analysts can devote more time to other pressing tasks, such as developing innovative strategies based on the insights found in the data.
