Leveraging language models, our experiments aim to automate\u0000information summarization and investment idea generation. We seek to evaluate\u0000the effectiveness of fine-tuning methods on a base model (Llama2) to achieve\u0000specific application-level goals, including providing insights into the impact\u0000of events on companies and sectors, understanding market condition\u0000relationships, generating investor-aligned investment ideas, and formatting\u0000results with stock recommendations and detailed explanations. Through\u0000state-of-the-art generative modeling techniques, the ultimate objective is to\u0000develop an AI agent prototype, liberating human investors from repetitive tasks\u0000and allowing a focus on high-level strategic thinking. The project encompasses\u0000a diverse corpus dataset, including research reports, investment memos, market\u0000news, and extensive time-series market data. We conducted three experiments\u0000applying unsupervised and supervised LoRA fine-tuning on the llama2_7b_hf_chat\u0000as the base model, as well as instruction fine-tuning on the GPT3.5 model.\u0000Statistical and human evaluations both show that the fine-tuned versions\u0000perform better in solving text modeling, summarization, reasoning, and finance\u0000domain questions, demonstrating a pivotal step towards enhancing\u0000decision-making processes in the financial domain.

The token is a cryptocurrency at\u0000any time stabilized by a basket of assets: reserves are invested in a portfolio\u0000composed long term by 50% of CeFi assets, comprised of Fixed Income, Equity,\u0000Mutual and Hedge Funds and 50% of diversified strategies focused on digital\u0000assets, mainly staking and LP farming on the major, battle tested DeFi\u0000protocols. The cryptocurrency, as well as the dollar before Bretton Woods, is\u0000always fully stabilized by vaulted proof of assets: it is born and managed as a\u0000decentralized token, minted by a Decentralized Autonomous Organization, and\u0000entirely stabilized by assets evaluated by professional independent third\u0000parties. Users will trade, pool, and exchange the token without any\u0000intermediary, being able to merge them into a Liquidity Pool whose rewards will\u0000be composed by both the trading fees and the liquidity rewards derived from the\u0000reserve's seigniorage.

{"title":"A Statistical Field Perspective on Capital Allocation and Accumulation","authors":"Pierre GosselinIF, Aïleen Lotz","doi":"arxiv-2312.16173","DOIUrl":"https://doi.org/arxiv-2312.16173","url":null,"abstract":"This paper provides a general method to translate a standard economic model\u0000with a large number of agents into a field-formalism model. This formalism\u0000preserves the system's interactions and microeconomic features at the\u0000individual level but reveals the emergence of collective states.We apply this\u0000method to a simple microeconomic framework of investors and firms. Both macro\u0000and micro aspects of the formalism are studied.At the macro-scale, the field\u0000formalism shows that, in each sector, three patterns of capital accumulation\u0000may emerge. A distribution of patterns across sectors constitute a collective\u0000state. Any change in external parameters or expectations in one sector will\u0000affect neighbouring sectors, inducing transitions between collective states and\u0000generating permanent fluctuations in patterns and flows of capital. Although\u0000changes in expectations can cause abrupt changes in collective states,\u0000transitions may be slow to occur. Due to its relative inertia, the real economy\u0000is bound to be more affected by these constant variations than the financial\u0000markets.At the micro-scale we compute the transition functions of individual\u0000agents and study their probabilistic dynamics in a given collective state, as a\u0000function of their initial state. We show that capital accumulation of an\u0000individual agent depends on various factors. The probability associated with\u0000each firm's trajectories is the result of several contradictory effects: the\u0000firm tends to shift towards sectors with the greatest long-term return, but\u0000must take into account the impact of its shift on its attractiveness for\u0000investors throughout its trajectory. Since this trajectory depends largely on\u0000the average capital of transition sectors, a firm's attractiveness during its\u0000relocation depends on the relative level of capital in those sectors. Moreover,\u0000the firm must also consider the effects of competition in the intermediate\u0000sectors that tends to oust under-capitalized firm towards sectors with lower\u0000average capital. For investors, capital allocation depends on their short and\u0000long-term returns and investors will tend to reallocate their capital to\u0000maximize both. The higher their level of capital, the stronger the\u0000re-allocation will be.","PeriodicalId":501372,"journal":{"name":"arXiv - QuantFin - General Finance","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139068645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The Paradox Of Just-in-Time Liquidity in Decentralized Exchanges: More Providers Can Sometimes Mean Less Liquidity","authors":"Agostino Capponi, Ruizhe Jia, Brian Zhu","doi":"arxiv-2311.18164","DOIUrl":"https://doi.org/arxiv-2311.18164","url":null,"abstract":"We study just-in-time (JIT) liquidity provision within blockchain-based\u0000decentralized exchanges (DEXs). In contrast to passive liquidity providers\u0000(LPs) who deposit assets into liquidity pools before observing order flows, JIT\u0000LPs take a more active approach. They monitor pending orders from public\u0000blockchain mempools and swiftly supply liquidity, only to withdraw it in the\u0000same block. Our game-theoretical analysis uncovers a paradoxical scenario: the\u0000presence of a JIT LP, rather than enhancing liquidity as expected, can\u0000inadvertently reduce it. A central reason behind the paradox is the adverse\u0000selection problem encountered by passive LPs, stemming from the presence of\u0000informed arbitrageurs. Unlike passive LPs, JIT LPs have the advantage of\u0000analyzing the order flow prior to providing liquidity and block confirmation.\u0000We show that this second-mover advantage mitigates their adverse selection\u0000costs and potentially crowds out passive LPs, particularly when order flows are\u0000not highly elastic to changes in pool liquidity. These equilibrium effects may\u0000lead to an overall reduction of pool liquidity and to an increased execution\u0000risk for liquidity demanders. To alleviate the detrimental effects of JIT\u0000liquidity, we propose a two-tiered fee structure for passive and JIT LPs. We\u0000show that this structure may prevent crowding out and improve welfare.","PeriodicalId":501372,"journal":{"name":"arXiv - QuantFin - General Finance","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138522833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"A Statistical Field Perspective on Capital Allocation and Accumulation: Individual dynamics","authors":"Pierre GosselinIF, Aïleen Lotz","doi":"arxiv-2401.06142","DOIUrl":"https://doi.org/arxiv-2401.06142","url":null,"abstract":"We have shown, in a series of articles, that a classical description of a\u0000large number of economic agents can be replaced by a statistical fields\u0000formalism. To better understand the accumulation and allocation of capital\u0000among different sectors, the present paper applies this statistical fields\u0000description to a large number of heterogeneous agents divided into two groups.\u0000The first group is composed of a large number of firms in different sectors\u0000that collectively own the entire physical capital. The second group, investors,\u0000holds the entire financial capital and allocates it between firms across\u0000sectors according to investment preferences, expected returns, and stock prices\u0000variations on financial markets. In return, firms pay dividends to their\u0000investors. Financial capital is thus a function of dividends and stock\u0000valuations, whereas physical capital is a function of the total capital\u0000allocated by the financial sector. Whereas our previous work focused on the\u0000background fields that describe potential long-term equilibria, here we compute\u0000the transition functions of individual agents and study their probabilistic\u0000dynamics in the background field, as a function of their initial state. We show\u0000that capital accumulation depends on various factors. The probability\u0000associated with each firm's trajectories is the result of several contradictory\u0000effects: the firm tends to shift towards sectors with the greatest long-term\u0000return, but must take into account the impact of its shift on its\u0000attractiveness for investors throughout its trajectory. Since this trajectory\u0000depends largely on the average capital of transition sectors, a firm's\u0000attractiveness during its relocation depends on the relative level of capital\u0000in those sectors. Thus, an under-capitalized firm reaching a high-capital\u0000sector will experience a loss of attractiveness, and subsequently, in\u0000investors. Moreover, the firm must also consider the effects of competition in\u0000the intermediate sectors. An under-capitalized firm will tend to be ousted out\u0000towards sectors with lower average capital, while an over-capitalized firm will\u0000tend to shift towards higher averagecapital sectors. For investors, capital\u0000allocation depends on their short and long-term returns. These returns are not\u0000independent: in the short-term, returns are composed of both the firm's\u0000dividends and the increase in its stock prices. In the long-term, returns are\u0000based on the firm's growth expectations, but also, indirectly, on expectations\u0000of higher stock prices. Investors' capital allocation directly depends on the\u0000volatility of stock prices and {ldots}rms'dividends. Investors will tend to\u0000reallocate their capital to maximize their short and long-term returns. The\u0000higher their level of capital, the stronger the reallocation will be.","PeriodicalId":501372,"journal":{"name":"arXiv - QuantFin - General Finance","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139469284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
