On October 6, 2023, I did a presentation (Available here: https://lnkd.in/etKDzmir) of a personal research focused on the Colombian stock market at the "Fourth International #Congress on #Finance and First International Congress on Business Strategy" at Universidad Pontificia Bolivariana, examining the #performance of various sectors and analyzing their interconnection.   This study delves into the local #Colombian #stock #market with a specific emphasis on #diversification viability. Its primary objective is to determine the feasibility of successful diversification within this market and to point out circumstances that require consideration of alternative investment avenues. To perform this analysis, I used daily historical market #data spanning from 2013 to 2023, covering thirty-two stocks traded on the Colombian #Stock #Exchange : bvc-Bolsa de Valores de Colombia S.A.   The research involved a comprehensive review of the historical performance of stocks categorized by #industry, evaluating their correlation and similarity. In addition, in the paper is identified the key points of tension in the markets, notably reflected in the fall of the general COLCAP and COLEQTY indices. Additionally, I examined the interconnectedness between industries, using “#spillover #effect” indices and contrasting the findings with periods of significant market distress.   The study culminated in the construction of optimal portfolios taking advantage of the efficient frontier concept, based on past historical data. Annual performance evaluations revealed that while #diversification within the Colombian market is feasible and advantageous, prudent investors should be prepared to diversify further during periods of low #liquidity or widespread market panic. Below I share my #work, which is also available on the congress webpage in the "Memories" section (Pages 64-73): https://lnkd.in/gN7VW7eU

Excited to witness initiatives like this that aims to create community and to advance Colombia's tech landscape. One of these days I will be an assistant, sooner than later. Two thoughts come to mind: 1. It's high time more cities like Bucaramanga, Tunja, and beyond step up to host similar events. As citizens, of these cities, we need to create the community and become such leaders to host them. 2. I hope to see Colombian researchers become interested around these kinds of events to do research that tackle our country's issues head-on.

📌 El próximo jueves 12 de septiembre se realizará un nuevo Seminario IMC, el cual estará a cargo de Leonardo Andrés Zepeda Núñez, investigador de Google Research. 📝 𝗧𝗶́𝘁𝘂𝗹𝗼: "Recent Advances in Probabilistic Scientific Machine Learning" 📑 𝗔𝗯𝘀𝘁𝗿𝗮𝗰𝘁: The advent of generative AI has turbocharged the development of a myriad of commercial applications, and it has slowly started to permeate into scientific computing. In this talk we discussed how recasting the formulation of old and new problems within a probabilistic approach opens the door to leverage and tailor state-of-the-art generative AI tools. As such, we review recent advancements in Probabilistic SciML – including computational fluid dynamics, inverse problems, and particularly climate sciences, with an emphasis on statistical downscaling. Statistical downscaling is a crucial tool for analyzing the regional effects of climate change under different climate models: it seeks to transform low-resolution data from a (potentially biased) coarse-grained numerical scheme (which is computationally inexpensive) into high-resolution data consistent with high-fidelity models. We recast this problem in a two-stage probabilistic framework using unpaired data by combining two transformations: a debiasing step performed by an optimal transport map, followed by an upsampling step achieved through a probabilistic conditional diffusion model. Our approach characterizes conditional distribution without requiring paired data and faithfully recovers relevant physical statistics, even from biased samples. We will show that our method generates statistically correct high-resolution outputs from low-resolution ones, for different chaotic systems, including well known climate models and weather data. We show that the framework is able to upsample up to 300x while accurately matching the statistics of relevant physical quantities – even when the low-frequency content of the inputs and outputs differs. This is a crucial yet challenging requirement that existing state-of-the-art methods usually struggle with. 📋 𝗕𝗶𝗼: Leonardo Zepeda-Núñez is a senior research scientist at Google Research based in Mountain View, California. He was previously an assistant professor of mathematics at the University of Wisconsin-Madison. Before that, he was a postdoctoral fellow at Lawrence Berkeley National Lab and UC Berkeley, and a visiting assistant professor at UC Irvine. He holds a PhD in Mathematics from MIT, an MSc from Sorbonne Université (formerly University of Paris VI), and a diploma from École Polytechnique. His research focuses on computational mathematics, particularly probabilistic methods in scientific machine learning, with applications to inverse problems and weather and climate modeling 📆 12/9 ⏰ 13:40 📍 Auditorio Edificio San Agustín, Campus San Joaquín. 🙋‍♂️ Evento sin inscripción y abierto a público. 📧 Link para transmisión vía Zoom disponible escribiendo a imc@uc.cl.

Being a desirable country to live comes with significant challenges. One of the most pressing is gentrification, which is reaching critical levels and causing severe societal impacts. For Costa Rica, a major consequence is the influx of cash into the country for large-scale land purchases and second-home construction. This has led to a 25% depreciation of the US dollar against the Costa Rican Colón. Those earning in dollars are particularly hard hit, as their expenses are in the local currency. Additionally, tourists and the export sector are feeling the pinch, with their purchasing power reduced by a quarter in an already expensive country. The University for International Cooperation recently celebrated its 30th anniversary and is now poised to address the monumental challenge of educating a new generation of professionals, whom we call "First Responders for Regeneration." To undertake this crucial mission, we urgently need financial support. These regenerators are essential worldwide. To facilitate this, we have established a new scholarship fund. The Buckminster Fuller Institute has graciously agreed to provide fiscal sponsorship for tax-deductible donations. If you or anyone you know is willing to support the future of our planet, please consider donating. You can securely donate online up to $5,000 at https://lnkd.in/e5ei2qA4. For larger donations or alternative methods, please contact us at rectoria@uci.ac.cr. For donations over $10,000, supported by the Buckminster Fuller Institute, please get in touch with Dr. Stuart Cowan at stuart@bfi.org.

Hub RD Just a few days ago, President Luis Abinader has officially declared the Dominican Republic as a logistics hub for the region! This strategic move is set to enhance our position in global trade and boost economic growth. The decision reflects our country's commitment to strengthening infrastructure, improving connectivity, and fostering international trade relationships. In an article from Listín Diario, just to mention one of many media that highlighted this news, outlines the ambitious plans to develop our logistics capabilities, including investments in port facilities, transportation networks, and trade facilitation measures. This initiative not only opens new opportunities for businesses but also positions the Dominican Republic as a key player in the logistics sector. This achievement has been a result of collective teamwork and a shared vision among all stakeholders in the sector. It’s a significant milestone and a dream realized for many. We anticipate this as just one of many steps to come that will further more our country’s global presence and economic potential. This development will have a profound impact on future generations of Dominican professionals in the international business field. Students and young professionals will benefit from new career opportunities, advanced training, and a more competitive edge in the global market. 🔗 Read the full article here: https://lnkd.in/eVfWBdJ6 We celebrate this milestone and look forward to the positive impact it will have on our economy, global trade connections, and the professional growth of our next leaders! #DominicanRepublic #LogisticsHub #EconomicGrowth #InternationalTrade #InfrastructureDevelopment #FutureProfessionals #Teamwork #Progress
