ILXQuant US Multi-Factor Low-Skewness Index

The sign-flipped twin of the Multi-Factor Right-Skewness Index. Universe, factors, sleeve ladder and equal weighting are identical -- each of value, profitability, investment discipline and momentum keeps its 150 strongest names -- but the second sort retains the 50 with the *lowest* expected idiosyncratic skewness rather than the highest. This is the sign documented by Boyer, Mitton and Vorkink, who find that investors overpay for lottery-like payoffs, so names with low expected upside tails earn higher average returns.
