Risk-adjusted momentum returns are usually estimated by constructing momentum portfolios and then running a full-sample regression of their returns on a set of factors (portfolio-level risk adjustment). This approach implicitly assumes constant factor exposure of the momentum portfolio.

The Journal of Finance, 1996 ABSTRACTWe examine whether the predictability of future returns from past returns is due to the market's underreaction to information, in particular to past earnings news. Past return and past earnings surprise each predict large drifts in future returns after controlling for the other.

Current Directions in Psychological Science, 2023
Our mental experience is largely continuous on the scale of seconds and minutes. However, this continuity does not always arise from a volitional carrying forward of ideas. Instead, recent actions, thoughts, dispositions, and emotions can persist in mind, continually shaping our later experience. Aspects of this fundamental property of human cognition—

Power generation and thermoelectric cooling enabled by momentum and energy multiband alignments
Science, 2021A cooler tin selenide Thermoelectric materials can convert heat into electricity or be used as the basis of cooling devices. Qin et al. found that doping a tin selenide thermoelectric material with lead and sodium improved the room temperature ...

The Physics Teacher, 2013
The gyroscope in a smartphone was employed in a physics laboratory setting to verify the conservation of angular momentum and the nonconservation of rotational kinetic energy. As is well-known, smartphones are ubiquitous on college campuses. These devices have a panoply of built-in sensors.

Momentum is primarily driven by firms' performance 12 to seven months prior to portfolio formation, not by a tendency of rising and falling stocks to keep rising and falling. Strategies based on recent past performance generate positive returns but are less profitable than those based on intermediate horizon past performance, especially among the ...

Has momentum lost its momentum?
Review of Quantitative Finance and Accounting, 2015We evaluate the robustness of momentum returns in the US stock market over the period 1965–2012. We find that momentum profits have become insignificant since the late 1990s. Investigations of momentum profits in high and low volatility months address the concerns about unprecedented levels of market volatility in this period rendering momentum ...

A GRU-RNN based momentum optimized algorithm for SOC estimation
, 2020For a lithium battery, a gated recurrent unit recurrent neural network (GRU-RNN) based momentum gradient method is investigated to estimate its state of charge (SOC). In the momentum gradient method, the current weight change direction takes a compromise
