Momentum profits are largely driven by institutional cash-management mechanics. Specifically, investors needing settled cash before month-end systematically sell their losers. And this predictable “dash-for-cash” creates a highly concentrated momentum effect during just six trading days every month.
A look at recent academic research connecting market volatility spikes to the underperformance of momentum strategies (especially for long/short versions of the strategy) The Big [...]
For most investors, private equity may not deliver the promised edge. There is a simpler, more liquid way to access the same economic exposure.
New research challenges a long-standing rule in momentum investing—and reveals surprising insights about when to use it For decades, investors using momentum strategies have followed [...]
There is a durable, stock-specific momentum component tied to how prices react to firm news around earnings dates. The result is a cleaner, lower-risk way to capture momentum without leaning so heavily on broad factor moves.
Stock momentum has long been a workhorse idea. Buy recent winners. Sell recent losers. Critics argue those profits mostly come from riding factor trends like [...]
Past returns often include non-repeatable revaluation alpha. Since structural alpha is the only component likely to persist, it’s essential for investors to distinguish this from one-off valuation windfalls before placing trust—or capital—in any factor or fund.
This paper shows there is a durable, stock-specific momentum component tied to how prices react to firm news around earnings dates. The result is a cleaner, lower-risk way to capture momentum without leaning so heavily on broad factor moves.
ChatGPT and similar large language models can enhance traditional investment strategies through superior interpretation of financial news. The improvements are economically meaningful, statistically robust, and persist under realistic implementation constraints.
Momentum works, across markets, time periods, and portfolio designs. But it also has weak spots, especially during market reversals, which risk-aware construction can help manage.
Diversification is the only free lunch in investing. If you’ve spent even a day exploring the world of finance, you’ve likely encountered this common truism. But chances are, you’ve also heard stories of someone turning a small stake into millions by going all-in on just one or two stocks. That contrast raises a natural question for many investors: how many stocks should I actually own in my portfolio? Too many stocks, and you might be leaving opportunities on the table. Too few and you risk losing your shirt! So how do we strike a balance?
If you’re a factor investor, there will come a time where you will have to choose between mom and dad: Should you combine or separate your factor exposures? And make no mistake: You will have to make a decision! While there’s no right answer, the way you structure your portfolio can have significant implications for returns, costs, and even your own behavior as an investor. Let’s walk through the logic behind both approaches.
Momentum investing remains a viable strategy. However, the way you construct and manage your momentum portfolio matters greatly.
Let’s break down how to build a robust factor portfolio—without getting lost in the weeds. We investigate which equity factors have the strongest historical returns and diversification benefits from a long-only perspective.
The main benefit of constructing industry momentum portfolios based on standard ICS is that it is straightforward and reproducible. However, that benefit may come at the cost of accuracy and oversimplification of complex industry relationships between companies.
When information about a company comes out gradually, investors might not react strongly, leading to momentum. Other factors, like how a company's value is perceived, also play a role, but to a lesser extent.
Underreaction to continuous news plays a key role in generating momentum internationally.
This paper provides new evidence on the efficacy of prioritizing transactions so as to focus portfolio turnover on the trades that offer the strongest signals and hence the highest potential performance impact.
Low short positions come from positive public news, while negative news can drive average short or extremely high short positions
There is strong empirical evidence demonstrating that momentum (both cross-sectional and time-series) provides information on the cross-section of returns of many risk assets and has generated alpha relative to existing asset pricing models.
