Full textThe goal of this thesis is to validate mathematically the brilliant conjecture by Clark (1973) who chose the volume as the subordinating process t defining the economic time in which asset prices should be observed. Along the lines of the recent microstructure literature and using the tick by tick data, we show, in agreement with the recent empirical results by Jones, Kaul and Lipson (1994), that it is in fact the number of trades which defines the economic time. We prove that without any assumption on the distribution of the stochastic time t we recover normality for asset price returns when using the number of trades as the "stochastic clock". We extract from a tick by tick data base the empirical distribution of asset returns and use a parametric estimation procedure to compute the moments of the unknown distribution of the subordinator t. The moments of t coincide with the corresponding moments of the number of trades. Lastly, we explain how the issue of stochastic volatility can be embedded in the general framework of stochastic time changes and what it implies for option pricing and hedging. The effectiveness of implied versus historical volatility in forecasting the future volatility has recently been, with good reasons, the subject of scrutiny both among academics and practitioners. It is common practice to use implied volatility as the market's forecast of future volatility. S&P 500 options and futures prices are used to show that implied volatility is a poor forecast of the realized volatility. The use of subordinated processes can help to construct a good forecast of the realized volatility. Moreover, our time change as well as our volatility forecast highlights the role of the rate of information arrival proxied by the number of trades

Full textThe volatility of securities is followed analytically on the financial markets by fractals theory introduced by Mandelbrot in 1950. This theory let determine the existence of the volatility long memory by introducing the R/S statistic (or "Hurst" exponent) defined by Lo (1991) and developped by Jacobsen (1996). The tests positive results attained on the analyse of the volatility do not concluded these obtained on the analyse of asset returns. We show indeed that the introduction of short term effect (autoregressiv models) in the statistic reduce the exponent value despite of the sample size : the long memory do not exist because of the short term-long term couple. The more transactions size is high the more the statistic value decrease : the sort term effect prevail on the long term effect ; the private and public information price depend on the investors strategic behavior of the session (the investors mimetism) function of the liquidity, the spread, the volume and the lead-lag effect criterias. An investor with an immediat reaction for speculation or liquid patterns lead a short term dependence of asser returns : their strategy depend on the evolution of past prices. We show that the short memory exist from an autoregressiv model modified GARCH introduced by Zumbach (1999). We can have a second approach of the short term effect from the duration between transaction prices and the volatility negativ correlation. We extend the modified GARCH(1,1) process of Zumbach by a mixed GARCH(1,1)-ACD process for getting account the duration factor. The results show that the asset returns short memory exist and the deviation of the errors estimations are lower with the mixed GARCH(1,1)-ACD process
