Quant investing, what is it, and what are some quant strategies?

What is quantitative investing?

Quantitative investing, or "quant" investing as it is often referred to, is a systematic approach to investing that uses numerical analysis and mathematical models to make investment decisions. The idea behind quant investing is that by analysing historical data and using algorithmic approaches, one can identify patterns in the market which may lead to more profitable and repeatable investment decisions.

Replace or include?

Quant investing does not have to replace traditional investments but can be used to supplement them when integrated as part of a diversified portfolio. By combining traditional investments and quantitative investing, investors can benefit from the strengths of both approaches and create a more robust investment strategy. Quantitative investing allows for greater customization and is often used to exploit short-term inefficiencies in the market that may not be noticed by traditional methods.

Strategy examples

Some examples of quantitative investment strategies are; portfolio rebalancing (ETF fund flow), momentum investing and risk-parity investing.

Portfolio rebalancing is a quantitative investing strategy which involves periodically buying and selling assets in order to maintain optimal risk, geographical, or volatility-based allocations.

Momentum investing is a quantitative investment strategy that seeks to capitalize on the momentum of stocks or other securities. Investors identify securities that have been increasing or decreasing in price and buy or sell them based on the statistical significance of how the momentum signal was generated.

Risk-parity investing is a quantitative investment strategy that seeks to create portfolios with equal levels of risk across different asset classes. This strategy analyses the risk of different securities and allocates them to create optimal portfolios with equal levels of risk in each asset class. For example, as risk in one asset class increases, a quantitative strategy would reduce exposure to this asset.

Overall, quantitative investing is a useful tool for investors looking to take advantage of short-term market inefficiencies. These market inefficiencies may occur at any moment during the trading session so having a quantitative operating continuously, allows an investor to respond to these market inefficiencies swiftly, as they occur.
