Multi-Period Trading via Convex Optimization - Original PDF
نویسندگان: خلاصه: Our investments will be in a universe of n assets, along with an associated cash account. We let ht ∈ Rn+1 denote the portfolio (or vector of positions or holdings) at the beginning of time period t, where (ht)i is the dollar value of asset i at the beginning of time period t, with (ht)i < 0 meaning a short position in asset i, for i = 1, . . . , n. The portfolio is long-only when the asset holdings are all nonnegative, i.e., (ht)i ≥ 0 for i = 1, . . . , n. The value of (ht)n+1 is the cash balance, with (ht)n+1 < 0 meaning that money is owed (or borrowed). The dollar value for the assets is determined using the reference prices pt ∈ Rn +, defined as the average of the bid and ask prices at the beginning of time period t. When (ht)n+1 = 0, the portfolio is fully invested, meaning that we hold (or owe) zero cash, and all our holdings (long and short) are in assets. Total value, exposure, and leverage. The total value (or net asset value, NAV) vt of the portfolio, in dollars, at time t is vt = 1T ht, where 1 is the vector with all entries one. (This is not quite the amount of cash the portfolio would yield on liquidation, due to transaction costs, discussed below.) Throughout this paper we will assume that vt > 0, i.e., the total portfolio value is positive. The vecto
Barometer of fear: an insider's account of rogue trading and the greatest banking scandal in history - Original PDF
نویسندگان: خلاصه: I had gone to India on holiday, and on the second day (it was 17 February 2009) I made a phone call to my manager at Merrill Lynch, who, as it happened, was also away from the office, telling him I wanted to talk. He said he was in a ski lift in Switzerland, and told me that he would call back in two or three hours. When he did, he initiated a conversation that would become the most difficult of my life. I informed him that my trading books were overvalued and had been so since mid-January. I had hoped that this would only be temporary but the markets had continued to move against me. ‘How much are we talking about?’ he asked. ‘It could be 100 million.’ ‘Why didn’t you tell me?’ ‘I really don’t know,’ I replied. ‘But now I feel ashamed. I want to apologise.’ Having opened the floodgates, the questioning began. I was interrogated about risk, volatility, hedging, 2008, liquidity, the credit crunch, Lehman Brothers, Merrill Lynch, other people’s losses, price movements, my previous boss, Bank of America, bonuses, profits, honesty, 2009, management, pressure, smoothing of profit and loss, exhaustion. Towards the end of our 45-minute conversation he asked: ‘Could this be a momentary lapse of reason?’ ‘Yes,’ I replied. ‘This is obviously very serious,’ he said. ‘It could go all the way up to the FSA.’

Knowledge as Culture: The New Sociology of Knowledge - Original PDF
نویسندگان: خلاصه: Drawing upon Marxist, French structuralist, and American pragmatist traditions, this lively and accessible introduction to the sociology of knowledge gives to its classic texts a fresh reading, arguing that various bodies of knowledge operate within culture to create powerful cultural dispositions, meanings, and categories. It looks at the cultural impact of the forms and images of mass media, and examines the authority of science, medicine, and law as bodies of contemporary knowledge and practice. Finally, it considers the concept of “engendered knowledge” through a consideration of the complex and often troubled relationship between women and science.
Sociology Beyond Societies: Mobilities for the Twenty First Century - Original PDF
نویسندگان: خلاصه: In this ground-breaking contribution to social theory, John Urry argues that the traditional basis of sociology — the study of society — is outmoded in an increasingly borderless world. If sociology is to make a pertinent contribution to the post societal era it must forget the social rigidities of the pre-global order and, instead, switch its focus to the study of both physical and virtual movement. In considering this sociology of mobilities, the book concerns itself with the travels of people, ideas, images, messages, waste products and money across international borders, and the implications these mobilities have to our experiences of time, space, dwelling and citizenship.
