A variance/volatility swap is an instrument that allows explicit exposure to the realized variance/volatility of an index, stock, etc., without exposure to other risks commonly encountered with derivatives: delta, gamma, etc.

We review the equity forward and futures pricing models. Consider an index level, I, at a future time, T. With respect to I, we calculate 1) the forward price, 2) the futures price, and 3) delta.

A valuation model is presented to calculate price, hedge ratio, and implied volatility for forward starting European calls and puts. The model focuses on the numerical accuracy of the implementation.

The model calculates numbers that characterize the effect of adding an extra instrument to a portfolio of loan commitments. To be useful, these numbers should be additive with respect to the facilities making up the portfolio, so that their total would have the same meaning for the portfolio as each individual number has for the respective…[Read more]

Pourquoi un sophisme est-il important ? Bouddha dit que « nous devenons ce que nous pensons ». Hier, je parlais à un diplômé philippin (je séjourne actuellement à Gneral Santos, aux Philippines). J’ai évoqué le principal argument martérialiste tel qu’expliqué par MIller et Thompson dans un article publié sur le site Web du NIH – Pubmed – qui affir…[Read more]

As the prominent social psychologists, Baumeister and Leary, point out, “Groups can share food, provide mates, and help care for offspring (including orphans). Some survival tasks such as hunting large animals or maintaining defensive vigilance against predatory enemies, are best accomplished by group cooperation…. Competition for limited res…[Read more]

The term ‘affective politics’ is sometimes used to dismiss political strategies as being directed merely at affects at the expense of rational analysis (Massumi 2015: 65f). While such uses are meant to criticize certain politics, appeals to the affects – and consequently, forms of propaganda or populism – do not have to be bad at all. The point h…[Read more]

Equity value at risk (VaR) model requires implied volatilities with respect to various indices and maturities, which range from three months to five years. A model is presented for generating a term-structure of implied equity index volatilities for use in calculating VaR.

A model is used to price a derivative whose payoff depends on returns over N periods on a shrinking basket of originally N assets. Each period, the worst return is added to the cumulative sum after being capped and floored, and the corresponding asset removed from the basket (hence a shrinking basket). The cap and floor rates are given for each…[Read more]

Credit value at risk (VaR) is used for measuring and analyzing credit risk of a portfolio. The basic methodology of the Credit VaR employs the credit migration approach spearheaded by RiskMetrics. It assumes that obligor’s credit quality is determined by the obligor’s asset value, which in turn is approximated by its standardized equity return.

Chaos theory is not as complex as it si often made out to be As Robert Juliano observes, the underlying principle is that “within the apparent randomness of chaotic complex systems, there are underlying patterns, interconnectedness, constant feedback loops, repetition, self-similarity, fractals, and self-organization.”

“Chaos has been for…[Read more]

Ang pagtanggi na ang “pagkamakasarili” ay ang laganap na pamantayan at mayroon lamang “limitadong mga anyo ng altruismo” Upang magsimula, idiin ko na, “Kahit na ang bakterya ay mas matagumpay sa pagpaparami sa presensya ng iba sa kanilang sariling mga species.” Ang ibig kong sabihin ay may connectivity ang bacteria para sa Diyos!

As the authors of the article “Beyond the Group Mind: A Quantitative Review of the Interindividual–Intergroup Discontinuity Effect” which was published in Psychological Bulletin, observed, It is estimated that just in the final decade of the twentieth century, the deadly wars of places like Rwanda, Bosnia, and Ethiopia claimed the lives of 30 m…[Read more]

Dawkins felslutning – vederläggning av att “egoism” är den vanliga normen och att det bara finns “begränsade former av altruism” Till att börja med vill jag betona att “även bakterier är mer reproduktivt framgångsrika i närvaro av andra av sin egen art.” Jag menar att bakterier har anslutningsmöjligheter för guds skull!

Extreme Individualism & Dawkins Fallacy Dawkins argues that “gene selfishness will usually give rise to selfishness in individual behaviour” – That is an excellent illustration in academia of what David Hay referred to as “Extreme Individualism” – a problem in Western Academia which Virgilio Enriquez also brought to light.

“Ideal theorists” in contemporary liberal political theory argue that we can only arrive at a conception of what our most important political values require by reference to an imagined ideal state of affairs and that we must therefore, to some extent, engage in utopian thinking. Critical theorists, from Marx and the Frankfurt School, have tra…[Read more]
