In the previous two articles, we explored the coverage of random portfolios in log volatility—return space, both with and without a risk-free asset. We now take the next step, and calculate the Efficient Frontier and Capital Market Line of Markowitz’s theory.

From an MMT (chartalist) perspective, cryptocurrencies lack sovereign backing and fail to establish the enforced demand necessary to function as true currency. Because they rely solely on speculative sentiment rather than legal mandates (like taxation), their values are unsustainable in the long run and risk ultimately collapsing to zero.

In 2008, I completed my first half-Ironman — then, later that same year, I took on the full Ironman distance at the traditional ExtremeMan in Hungary, finishing in 13 hours and 38 minutes. By 2013, I had knocked my time down to 11 hours and 36 minutes. Since then, I’ve racked up a total of 56 triathlon finishes. 2024 was one of the best years so far, with a record of 10 triathlon races.

In a previous article I simulated random portfolios using Monte Carlo methods for the 2023 daily closing prices of the 100 stocks constituting the Nasdaq-100. Here I add the risk-free asset to the portfolio and examine how it affects the coverage in log volatility—return space.

This post provides a practical Individual Career Plan template you can use to guide self-assessment, prioritize your professional development, and set meaningful goals that align with your vision for the future. By outlining clear objectives and action steps, you create a framework for continuous improvement and more informed career decisions. I use this same template for the data organization I lead, filled it out myself, and shared it with others to inspire them to do the same.

Hungary’s rushed entry into World War II and its botched attempt to break away from it show how stale leadership trapped in its own fantasy bubble can steer a nation toward disaster. By “political backtesting” these moments — comparing their underlying factors to the present — today’s citizens can weigh future outcomes, draw practical lessons, we can make more informed decisions about where and how to live.

I run Monte Carlo simulations of content production over random Watts-Strogatz graphs to show various effects relevant to modeling and understanding Randomized Controlled Trials on social networks: the network effect, spillover effect, experiment dampening effect, intrinsic dampening effect, clustering effect, degree distribution effect and the experiment size effect. I will also define some simple metrics to measure their strength. When running experiments these potentially unexpected effects must be understood and controlled for in some manner, such as modeling the underlying graph structure to establish a baseline.

I examine the coverage of random portfolios in log volatility—return space using Monte Carlo methods with different randomization techniques for the 2023 daily closing prices of the 100 stocks constituting the Nasdaq-100.

This blog post explores foundational quantum mechanics concepts such as superposition, entanglement, and the challenges posed by locality and determinism, while highlighting the historical efforts of Einstein and Bohm to reconcile these phenomena with hidden variable theories.

In February 2016, I made a life-changing decision to leave Hungary and seek opportunities abroad, starting in London and later moving to Dubai. This essay explores the multitude of reasons behind my choice and why I have no immediate plans to return to Hungary.

Screening CVs is a critical step in the hiring process, used to determine which candidates progress further in the hiring funnel. While the approach to CV screening can vary by company and industry, the primary goal remains the same: to identify candidates with the potential to succeed in subsequent interview stages.
