Machine Learning in Finance: More Than Just Buzzwords

Machine learning and artificial intelligence are often seen as mysterious and inaccessible, reserved only for geniuses and tech giants. However, to the average person, these terms are overhyped and misunderstood. In reality, building algorithms using machine learning and AI is far from easy.

The typical application of machine learning in finance involves techniques like linear regression for speed traders and sophisticated statistical models for lower-frequency trading. These methods involve analyzing large datasets, often including news articles, Twitter threads, and other sources of alternative data. Machine learning programs adapt and learn from their environment without explicit instructions, allowing for more accurate predictions and trading signals.

Machine learning is used in finance for:

Generating signals for trades Testing machine hypotheses with statistical models to determine the strength of signals and the profitability of strategies

Due to the competitive nature of the financial industry, most firms closely guard their machine learning strategies, viewing them as vital competitive advantages. Hence, detailed information about these strategies is scarce, as revealing them could put the firms at a disadvantage.

Notable Hedge Funds Using ML for Trading
