The performance of traditional equity factor strategies have been rather disappointing
in recent years. In our latest research, we consider incorporating sentiment signals
from news, earnings call transcripts, and insider transactions to boost the
risk-adjusted returns, and revive factor performance.
In this whitepaper, we analyze how the performance of monthly-rebalanced equity factor
investing strategies can be significantly enhanced by incorporating real-time sentiment from
RavenPack’s news analytics and earnings transcripts datasets. We construct cross-sectional,
dollar-neutral long-short portfolios as our benchmarks for nine traditional style factors
based on the small, mid and large-cap U.S. stock universes over 2007-2021.
Tilting the weights of a monthly-rebalanced benchmark factor portfolio using
sentiment enhances strategy performance across all equity factors, while maintaining
stable portfolio turnovers.
Tilting towards earnings-related news sentiment increases Information Ratios for
yield (from -0.21 to 0.28) and investment factors (from 0.30 to 0.61), while
portfolio turnover marginally increases from 3.2% to 5.7% and from 4.2% to 6.4%,
Statistical significance tests confirm that sentiment-tilted factors meaningfully
outperform those with random tilts, indicating that the information contained in
news and transcripts adds considerable value in the signal construction process.

sentiment-tilted multifactor strategies.
