One of the newest and most controversial approaches to financialpricing. Search result 3 of 4. This is a fibre bundle; the fibres are the vector spaces. The vectors in these internal spaces, spread out over real space, are called the matter field. There is a rule that specifies how to compare vectors attached to different points - how to do parallel transport. The rule is called a connection, or a gauge field. If, when you move along a closed path, the vector you start with is not the same as the one you end with, then the gauge field is curved. The bigger the difference between the vectors, the larger the curvature of the connection. Both fields, matter and gauge, change over time, obeying a principle of least action. The world does not care how we measure things. In particular, gauge transformations - rotations of the internal vector spaces - are physically irrelevant. We can rotate the internal space of each point however we like, as long as the rotations are continuous from point to point. The gauge field changes along with the matter fields, so that vectors which were parallel before, stay parallel. But the action, and so the motions dictated by it, must be gauge invariant. This constrains how the action can depend on the matter and gauge fields. If we choose the simplest gauge-invariant action, it says, in effect, that matter moves along trajectories of minimal curvature, and that the connection grows curved near masses. The gauge field guides the matter field, and the matter field puts curvature in the gauge field; curvature is force. Each of the fundamental forces of nature gravity, electromagnetism and the weak and strong nuclear forces corresponds to a different gauge field, the connection for a fibre bundle with a different internal vector space. Fundamental physics is about fibre bundles, connections, gauge invariance and statistical fluctuations about the least-action trajectory. Getting a degree in mathematical physics is about learning to do calculations about fibre bundles, connections, gauge invariance and statistical fluctuations Note1. Now, Kirill Ilinski has a degree in mathematical physics Think, he says, about what we do when we calculate net present values. We employ a rule that lets us compare the value of commodity bundles at different times, by specifying equivalent values at a common time. Commodity bundles are vectors in commodity space; calculating net present value is engaging in parallel transport of these vectors according to a connection. To really compare the value of commodity bundles, we need a connection that includes prices and discounting as its spatial and temporal components. Suppose this connection has non-zero curvature. Then we can make a series of exchanges and end up with a commodity bundle whose value is not the same as the one we started with - i. Curvature is excess returns; curved paths are arbitrage opportunities. Gauge transformations are changes in the units we use to measure commodities - going from denominating hog bellies by the gross to denominating by the hundred, for instance, or counting money in dollars or pennies. These gauge changes are dilations, not the rotations of physics, but the same idea applies. In particular, exploiting arbitrage opportunities should tend to make them go away - matter should redistribute itself so as to even out prices. Second, the dynamics should, just as in physics, be governed by the principle of least action. Here this corresponds in part to utility maximization on the part of traders. Third, the form of the action should be gauge invariant. But gauge invariance tightly limits the form of the action; there are only a few possibilities that are invariant and simple. These requirements are not enough to fix the form of the action and so the dynamics. Ilinski assumes that the connections are stochastic functions of time - that changes in prices are at least partially random. Similarly, the response of the matter fields to the gauge fields - how traders respond to prices - is also stochastic. Putting these together, he formulates an action that lets him calculate the price dynamics of asset markets, first with just a single trader, and then with a fluctuating number of interacting traders. Handling a variable number of traders needs some tricks from field theory, explained in an appendix. It even explains why pieces of technical analysis that look little better than voodoo can work over short time horizons, while the long run looks comfortingly close to the efficient market hypothesis. Having built up this model, Ilinski goes on to apply it, in detail, to pricing assets, especially derivatives. It is notable - Page 1

2 and he duly notes it - that he needs to make no assumption of economic equilibrium, or even of near-equilibrium, though he can reproduce equilibrium results e. Black-Scholes in the appropriate limits. This material is not just an addendum it runs to nearly a hundred pages, but is too detailed for discussion here. Is any of this believable? Nor is it particularly contentious that people respond to prices that is what they are for and that trades change prices that is supply and demand. And this is not peculiar to finance - it should work for markets generally, even with production and consumption. That a least-action principle should govern the dynamics is less obvious. Ilinski gets one by assuming traders are boundedly rational in a way that is mathematically tractable, and not outrageous empirically, but vastly simpler than the real cognitive mechanisms underlying choice and action. Are behaviourally-realistic dynamics action minimizing? Is there any way of capturing strategic interaction in a minimum-action principle? Note2 Even if we give Ilinski an action principle, we do not have to give him gauge invariance. That symmetry makes sense in physics, because our measurement conventions really do not make any difference to nature. But gauge symmetry is definitely broken in real markets, in many ways - psychological effects, certain kinds of transaction costs etc. Ilinski knows this, and wants to handle those effects as small perturbations - but are they? All these matters need more investigation. And the models themselves have many virtues: IOP is an excellent exposition of this approach. Page 2

In this paper, we analyze and compare long-range power-law correlations of returns, absolute returns, squared returns, cubed returns and square waved returns for sixteen individual stocks from the block of energy sources of Chinese stock market and five stock indices Shanghai Composite Index, Shenz And the exponent trends of the returns are close to that of square waved returns. Also, five indices deviate from other sixteen individual energy stocks in all cases except square waved returns. Further, there are long-range correlations and persistence in volatility series of absolute returns and squared returns. We find that the China energy market exhibits fractal and persistence properties.

Applying the theory of statistical physics systems â the voter model, a random stock price model is modeled and studied in this paper, where the voter model is a continuous time Markov process. Moreover, we investigate the power-law distributions, the long-term memory of returns and the volatility clustering phenomena for the Chinese stock indices.

June 16, Time: We analyse the dynamics of the Warsaw Stock Exchange index WIG at a daily time horizon before and after its well defined local maxima of the cusp-like shape decorated with oscillations. The rising and falling paths of the index peaks can be described by the Mittag-Leffler function superposed with va The rising and falling paths of the index peaks can be described by the Mittag-Leffler function superposed with various types of oscillations. The latter is a solution of our model of index dynamics defined by the nonhomogeneous fractional relaxation equation. This solution is a generalised analog of an exactly solvable model of viscoelastic materials. We found that the Warsaw Stock Exchange can be considered as an intermediate system lying between two complex ones, defined by short and long-time limits of the Mittag-Leffler function; these limits are given by the Kohlraush-Williams-Watts law for the initial times, and the power-law or the Nutting law for asymptotic time. The methods and even algorithms that have been explored for description of physical phenomena become an effective background and inspiration for very productive methods used in analysis of economica Chapter 4 : A smoking gun linking Economics to Physics?
