What Is Alternative Data Investing
What if you could count the cars in a parking lot by satellite, or guess a company's sales in advance from card payment data? Using such 'unusual data' is alternative data investing.
What Alternative Data Is
Alternative data means using non-traditional data — rather than conventional sources like financial statements or economic indicators — for investment decisions.
Representative examples include satellite imagery, credit card payment records, location and foot-traffic data, app usage, web traffic, and social media sentiment.
For example, reading visitor trends from satellite images of a big-box store's parking lot, or trying to gauge a company's sales flow from card payment data before the official earnings release.
Who Uses It, and Why
Alternative data is used mainly by institutional investors — hedge funds, asset managers, private equity — to 'see faster and differently than others.'
1. Card payment data — Valued as especially useful because it directly observes company-level spending. 2. Satellite data — Looks down from above at factory operations, retail visits, crop conditions, shipping volumes, and more.
Market-size estimates vary widely by source. From under $1 billion in 2016, it grew to around $6-7 billion by about 2023, and some reports project it to reach tens of billions to over $100 billion by the 2030s (with estimated CAGRs of 28-54%, etc.).
Market-size and growth-rate figures differ greatly by research firm. Source: Deloitte 'Alternative data at investment management firms,' Datarade 'What is Alternative Data.' The broader the scope, the larger the figures.
Limits and Risks
Alternative data is not a cure-all; rather, it carries several traps.
1. Data bias — Data skewed toward certain regions or groups produces wrong conclusions. 2. Privacy and legal issues — If it involves personal information or material non-public information (MNPI), it becomes a legal problem. 3. Overfitting — Rules tailored to past data may not fit the future (backtest overfitting). 4. Cost and competition — Good data is expensive, and the edge disappears once many people use it.
Remember that alternative data is hard and expensive for individuals to access, and 'having a lot of data' does not lead to 'guaranteed returns.'
This article does not recommend any specific data or strategy. Its purpose is to explain the concept and its limits.
Frequently Asked Questions
Q. Can individual investors use alternative data?
You can access some free or low-cost data, but premium data such as satellite or card data is generally expensive and distributed mainly among institutions. Access itself is limited.
Q. Does using alternative data raise returns?
It is not guaranteed. Data bias, overfitting, and intensifying competition can erode any edge, and misinterpretation can actually lead to losses.
