It is hard to successfully time any investment. Adjusting a portfolio based on expectations about the future can easily backfire because the future is hard to predict. Yet there is an emerging body of research that suggests it is possible to successfully time exposure to factors like value, momentum, small size, quality, and low volatility. While each of these factors has a good long-term record, they all go through cycles of underperformance. If timing really works, it could help mitigate this cyclicality, which is one of the biggest drawbacks to factor investing.
