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]

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.

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]

The following is a collection of identified fictional and non–fictional writing by Thomas Richards (1800-1877). Originally from Dolgellau, the young medical practitioner Richards published a considerable number of antiquarian and critical essays, editorials, travel writing, short stories and poetry in literary periodicals in England, Scotland a…[Read more]

In the first decades of the twentieth century, the Madrid-based Galician journalist Julio Camba (1882–1962) acquired long-lasting fame as a travel writer thanks to his foreign chronicles published in the Spanish press and subsequently compiled in a series of volumes. La rana viajera [The Travelling Frog] (1920), however, gathers some of the p…[Read more]

Travel has always been an extremely important theme in Irish-language literature, but often this travel was motivated by financial hardship and, up until the late twentieth century, Irish-language accounts of travel largely documented the emigrant experience. In more recent years, however, Irish-language literature has witnessed a transition from…[Read more]

Guidebooks play an important role in increasing the visibility of a nation, as they introduce the country to potential visitors and create images prior to travelling. However, they also tend to reinforce stereotypes and create “romantic fictions” (Mahn 2008). This article examines the representation of Wales in French and German guidebooks and con…[Read more]

This article examines Derek Walcott’s “travel poems” about Wales and England from the collections The Fortunate Traveller (1981) and Midsummer (1984) through the prism of Deleuze and Guattari’s concept of littérature mineure. As a Caribbean poet, Walcott is placed both outside the centre of “majority”, post-imperial civilisation and within the s…[Read more]

In spite of a burgeoning recognition of the Welsh language as part of a wider appreciation of Welsh culture at the beginning of the nineteenth century (see Constantine 2014: 124), Home Tour writing about Wales remained largely Anglocentric (Borm, quoted in Colbert 2012: 85). The journals written by lady’s companions, Eliza and Millicent Bant, in 1…[Read more]

We present a model for pricing a credit derivative product where party A has sold default put protection on a Euro denominated bond. Specifically, upon bond issuer default, party A must pay to party B a notional amount of 10 million USD (excluding accrued interest). In exchange, party B must pay a fixed rate to party A, on a quarterly basis,…[Read more]

We present a valuation model for pricing a gold derivatives trade. The trade can be structured to synthesize a typical gold-miner’s hedge, specifically, a swap in which one party receives long-term interest rates and pays a blend of short-term interest rates and short-term gold lease rates.

We present a model for pricing a path-dependent, equity-linked payoff. Here a bounded price return is calculated from an underlying index at certain pre-specified dates. The total return at maturity is given by the sum of the bounded price returns above, but where a specified number of the highest of these returns are set to a cap value.

A model is presented for pricing an American call option on stock. The option tenor is n years, and its strike price is increased every anniversary. It has also the following feature: if the stock price stays in excess of 200% of the current strike price during 10 consecutive trading days. The seller can issue a notice to the buyer that one half…[Read more]
