Valuation-based market timing demonstrates strong potential to improve risk-adjusted returns for conservative long-term investors. Such timing strategies based on the cyclically-adjusted price-earnings ratio provide comparable returns as a 100 percent stocks buy-and-hold strategy but with...

While most everyone would agree that valuations matter, the question remains as to whether clients with a long-term outlook (such as those planning for retirement) can hope to act successfully on information about valuations. This article provides favorable evidence based on the historical...

In this paper I study the relationship between rationality and asset prices when agents have heterogeneous and incorrect beliefs about future events. Using the fully rational pricing as a benchmark, I show that when agents behave according to the Subjective Generalized Kelly rule (Bottazzi et...

Factorial moments are convenient tools in nuclear physics to characterize the multiplicity distributions when phase-space resolution (Delta) becomes small. For uncorrelated particle production within Delta, Gaussian statistics holds and factorial moments Fq are equal to unity for all orders q....

Classical quantitative finance models such as the Geometric Brownian Motion or its later extensions such as local or stochastic volatility models do not make sense when seen from a physics-based perspective, as they are all equivalent to a negative mass oscillator with a noise. This paper...

Valuation-based market timing demonstrates greater potential to improve risk-adjusted returns for conservative long-term investors than given credit by Fisher and Statman (2006). On a risk-adjusted basis, market-timing strategies provide comparable returns as a 100 percent stocks buy-and-hold...

Focusing on a “safe withdrawal rate” and then deriving a “wealth accumulation target” to achieve by the retirement date may not be the best way to approach retirement planning. Such a formulation isolates the working (accumulation) and retirement (decumulation) phases. When considered...

The aim of traditional retirement planning is to set a wealth accumulation target for your retirement date so that your desired expenditures can be obtained using a "safe" withdrawal rate. But it is quite difficult to know if you are making progress toward this target. Volatility over short...

Within a financial market where a risk-free bond and a long-lived risky asset are exchanged by investors with heterogeneous trading rules, we assume that the investors most exposed to the risky asset are subject to joint liquidation needs. The latter encompass a risk whenever the market impact...

We administer a newly-designed survey to a large panel of retail investors who have substantial wealth invested in financial markets. The survey elicits beliefs that are crucial for macroeconomics and finance, and matches respondents with administrative data on their portfolio composition and...
