Classic studies of the probability density of price fluctuations $g$ for stocks and foreign exchanges of several highly developed economies have been interpreted using a {\it power-law} probability density function $P(g) \sim g^{-(\alpha+1)}$ with exponent values $\alpha 2$, which are outside...

Classic studies of the probability density of price fluctuations g for stocks and foreign exchanges of several highly developed economies have been interpreted using a power-law probability density function P(g) g−(α+1) with exponent values α 2, which are outside the L´evy-stable regime 0 ...

Tim Berners Lee's vision of the Semantic Web (Web 3.0) as defined in his 2001 paper with Hendler and Lassila though accurate is incomplete. The evolution of the web is not going to stop at its cognitive stage but will move towards becoming an ultra-smart agent and for that to happen the web...

The financial markets are not only changing internally but also externally as blockchain starts to change the infrastructure landscape. The falling fees for investment management is creating a more accountable financial industry and forcing the stock market to also question its broader role in...

While Robert Solow suggested not to think of Economics as Science, Andrew Lo warned us about the dangers of using Physics to build economic systems. Physics has been a late entrant to the world of Finance. The subject has reached critical mass to answer some of the biggest challenges of Finance...

Adaptive Market Hypothesis (AMH) embraces Efficient Market Hypothesis (EMH) as an idealization that is economically unrealizable, but which serves as a useful benchmark for measuring relative efficiency. AMH's adaptability to changing dynamics of the market suggests that investors are...

There is no disagreement regarding the statistics of mean reversion. What goes up comes down and vice versa. Campbell and Shiller (1988) said that the simple theory of mean reversion was basically right. Fama and French (1989) also suggest that valuation ratios forecast five-year returns with...

Though ‘Size' is the most important factor explaining stock market returns the possibility of size being a proxy was first mentioned in Banz (1978). Even after forty years of factor investing the industry is still looking for answers. This paper chronologically lists the research on ‘Size'...

Information is an assumption for modern finance. The Efficient Market Hypothesis uses information to back its case of efficiency. The EMH case is weak, but as Martin Swell (2011) explains, until a flawed hypothesis is replaced by better hypothesis, criticism is of limited value. This paper...

The work of Jules Regnault, Francis Galton, John Rae and Vilfredo Pareto covered Duration, Behavior, and Value. Regnault talked about stock market science, statistical nature of Value, duration importance and price behavior. Galton laid the foundation for the robust behavior of Reversion in...
