Linear Algebra and Optimizations are two important subjects required for Data Science.
Alternative data in finance refers to data used to obtain insight into the investment process. Alternative data sets are often categorized as big data ,  which means that they may be very large and complex and often cannot be handled by software traditionally used for storing or handling data , such as Microsoft Excel.
An alternative data set can be compiled from various sources such as financial transactions , sensors , mobile devices , satellites , public records , and the internet. Since alternative data sets originate as a product of a company's operations, these data sets are often less readily accessible and less structured than traditional sources of data.
During the last decade, many data brokers , aggregators , and other intermediaries began specializing in providing alternative data to investors and analysts. Alternative data is being used by fundamental and quantitative institutional investors to create innovative sources of alpha. The field is still in the early phases of development, yet depending on the resources and risk tolerance of a fund , multiple approaches abound to participate in this new paradigm.
The process to extract benefits from alternative data can be extremely challenging. The analytics , systems , and technologies for processing such data are relatively new and most institutional investors do not have capabilities to integrate alternative data into their investment decision process.
Most alternative data research projects are lengthy and resource intensive; therefore, due-diligence is required before working with a data set. The due-diligence should include an approval from the compliance team, validation of processes that create and deliver this data set , and identification of investment insights that can be additive to the investment process.
It's possible to predict geopolitical risk through a profound alternative data analysis, while social media sites reveal a host of data for consumer sentiment analysis. In finance , Alternative data is often analysed in the following ways:.
While compliance and internal regulation are widely practiced in the alternative data field, there exists a need for an industry-wide best practices standard. Such a standard should address personally identifiable information PII obfuscation and access scheme requirements among other issues. Compliance professionals and decision makers can benefit from proactively creating internal guidelines for data operations. Investment Data Standards Organization IDSO was established to develop, maintain, and promote industry-wide standards and best practices for the Alternative Data industry.
Legal aspects surrounding web scraping of alternative data have yet to be defined. Current best practices address the following issues when determining legal compliance of web crawling operations:. Web scraped data refers to data harvested from public websites. With 4 billion webpages and 1. The companies that specialize in this type of data collection, like Thinknum Alternative Data    , write programs that access targeted websites and collect and store the scraped information on a periodic basis.
In some cases web scraping requires use of public APIs as a way to access the data within those pages directly without visiting the actual website. Types of web scraped data include:. It is crucial that managers and data vendors fully understand all risks when selling and using new data. From Wikipedia, the free encyclopedia.

Machine Learning methods to analyze large and complex datasets: There have been significant developments in the field of pattern recognition and function approximation uncovering relationship between variables. Machine Learning techniques enable analysis of large and unstructured datasets and construction of trading strategies. While neural networks have been around for decades10, it was only in recent years that they found a broad application across industries. This success of advanced Machine Learning algorithms in solving complex problems is increasingly enticing investment managers to use the same algorithms. While there is a lot of hype around Big Data and Machine Learning, researchers estimate that just 0. These developments provide a compelling reason for market participants to invest in learning about new datasets and Machine Learning toolkits.

Fixed income investing has undergone a sea change in the past decade. By tossing out some active management orthodoxies and embracing new technologies and quantitative techniques, we believe some managers are better equipped to capture unique insights and excess returns for their clients.

AI and machine learning have had successful applications in the financial sector even before the entry of the mobile banking ecosystem. AI is being used to leverage insights from data for financial investing and trading, wealth management, asset management, and risk management. Investors and financial advisors have relied on the existing information they have about stocks and company performance from SEC filings. As smartphones and devices multiply, cameras and other sensors boom, and organizations increasingly ground their business processes in data, new kinds of analysis are opening up for traders and investors to make more informed decisions about the world — beyond traditional data sources like stock price activity or earnings reports. According to Anwar:. The bulk of the quantamental analysts are using quantitative methods to analyze alternative data and the output is a piece to the puzzle in their fundamental analysis. These kinds of analysis would be entirely impossible without the proliferation of new data sources, and the development of new AI methods.
Big data usually involves collating data generated at various speeds and moments and accommodating bursts of activity. IDSO was established to support the growth of the Alternative Data industry through the creation, development, and maintenance of industry-wide standards and best practices. We find that stock indices returns exhibit long-range correlations, supporting the idea that the.

Defensible alt-data strategies, meanwhile, can help Investors increase the excludability of an Kolanovic and Krishnamachari proposed another taxonomical schema for alt-data Although big data and alt-data are not perfectly identical, there are cases in which alt-data qualify as big data. Data Visualization Priciples and Practice.
Alpha, the excess return of a fund relative to the return of the benchmark index, is what portfolio managers are typically measured against. However, since the financial crisis in and , it has become increasingly difficult to consistently generate alpha based on traditional investment styles and strategies. One reason is the overcrowding of popular investment strategies and therewith the dependence of many portfolios on the same risk factors to create investment returns. Another reason is that most buy side firms nowadays already have access to the very same, ever increasing data sets—mostly related to market price data down to the tick or even order book level. Portfolio managers need to invest in and apply new approaches to data analysis and the creation of investment ideas and strategies. Two major trends are there to help.
