Order Book Filtration and Directional Signal Extraction at High Frequency
With the advent of electronic capital markets and algorithmic trading agents, the number of events in tick-by-tick market data has exploded. A large fraction of these orders is transient. Their ephemeral character degrades the informativeness of directional alphas derived from the limit order book (LOB) state. We investigate whether directional signals such as order book imbalance (OBI) can be improved by structurally filtering high-frequency LOB data. Three real-time, observable filtration sch…

Domestic capital is growing with regulatory support.

Portfolio optimization in incomplete markets and price constraints determined by maximum entropy in the mean
A solution to a portfolio optimization problem is always conditioned by constraints on the initial capital and the price of the available market assets. If a risk neutral measure is known, then the price of each asset is the discounted expected value of the asset's price under this measure. But if the market is incomplete, the risk neutral measure is not unique, and there is a range of possible prices for each asset, which can be identified with bid-ask ranges. We present in this paper an effec…

An analysis of capital market through the lens of integral transforms: exploring efficient markets and information asymmetry
Post Modigliani and Miller (1958), the concept of usage of arbitrage created a permanent mark on the discourses of financial framework. The arbitrage process is largely based on information dissemination amongst the stakeholders operating in the financial market. The advent of the efficient market Hypothesis draws close to the M&M hypothesis. Giving importance to the arbitrage process, which effects the price discovery in the stock market. This divided the market as random and efficient cohort …
