Quantitative trading and smart - contract - driven strategies can improve trading efficiency by quickly executing large - scale trades. They can also contribute to more accurate price discovery as they are based on algorithms and real - time data. In terms of volatility, they can either exacerbate it if there are large - scale automated sell - offs or dampen it if they are used for market - making. In a bull market, these new strategies may generate higher returns than traditional ones as they can quickly capture market trends. In a bear market, they may also be better at risk management. Investors should consider their risk tolerance, investment goals, and technical knowledge when choosing strategies. For example, less - experienced investors may prefer more traditional buy - and - hold strategies, while more sophisticated investors can explore quantitative trading.
