Launching a career as a risk quant requires a well-thought-out strategy that combines a strong educational foundation, technical skills, and an understanding of the evolving landscape of risk management. To embark on this journey, aspiring risk quants should start by building a solid educational

Although the relationship is not immediately clear and obvious, the structural engineering has a lot in common with financial assets. In both cases we deal with the objects under stress over their entire lifetimes. There are two possible outcomes: something can break or perform well. The engineers

Crypto-market price actions often revolves around the news. Good or bad? It does not matter. However, the recent long-term battle between the SEC and Ripple seemed to reignite the markets. On July 13, 2023, XRP/USDT suddenly shoot up, dragging a number of not so obvious cryptos up along. This was

In time-series analysis we often examine signals for specific volatility patterns. The simplest one is a periodic or quasi-periodic modulation. In finance these modulations are of paramount importance allowing for signal decomposition, separating short-term variations from long-term trends.

In crypto market, stablecoins are meant to maintain their constant value with respect to the underlying currency. At least in theory. The problem begins with an idea of stablecoin’s value to be stable or being stabilised over time. Different backup mechanisms are at work. For example, Tether

There is a huge number of ways how one can transform financial times-series in order to discover new information about changing price dynamics. We talk here about certain transformation that takes price time-series (or return-series) and transforms it into a new domain. Every solid textbook on

Thanks to the courtesy of Packt Publishing, I had the pleasure of receiving, reading, and studying the new release of Python for Finance Cookbook, the book by Eryk Lewinson. This is the second (and probably the last) edition, according to the author himself. Therefore, it must be solid and

It is needless to say about next big thing in the field of artificial intelligence (AI) known as ChatGPT. ChatGPT is a large language model developed by OpenAI. It is based on the GPT (Generative Pre-training Transformer) architecture and is trained on a massive dataset of text data. This allows it

We kicked off a new series of go-to solutions for #Cryptocurrencies with #Python. Subscribe to our YouTube channel for regular updates!

In quantitative finance, the Volatility of Volatility (also referred to as Vol-of-Vol or VoV) is an important parameter for pricing various derivative products (e.g. Volatility Dispersion Swaps) and its correct estimation is frequently desired. VoV is usually a single number treated an an input

Here is the first episode in a new series of podcasts entitled Break into Finance. We will be talking about what it takes to launch your career in finance, what does it mean to become a quant, and where to start. Any questions welcomed!

Surprisingly, in the literature there are only few effective formulae for asset allocation. They are based on the asset types and, in theory, they should define investors’ risk appetite. For instance, a large exposure in stocks should define aggressive investment style in comparison to investing

The Internet is full of articles covering all kinds of aspects related to finance. Stocks, crypto, indexes have always been a hot topic and many are seeking new ideas in these areas. It is true that in a vast amount of the content one may get lost. There are tons of blogs with irrelevant, outdated,

A clear and informative time-series visualisation is often a challenge. Especially this is true when it comes to candlestick charts in Python. Searching the Web for a perfect solution may bring you to the Plotly package which stores in its arsenal the corresponding function allowing for easy

A quantitative research over the construction of a perfect crypto-portfolio can be based on a number of crypto-assets. The selection of them is of paramount importance. If you are able to build the right portfolio, stick to it, or successfully manage its composition in time (e.g. through the method

There is no question about how profitable the trading of cryptocurrencies can be. If you create an algorithmic strategy and stick to it, you can capture a +10% PnL wave sometimes even twice a day for a selected asset. Unfortunately, the opposite is true, too! The crypto-risks seem to follow the same

In quantitative finance, we very often deal with a sample mean and sample standard deviation being derived given a vector or a time-series or any other (1-dimensional) dataset. For many of us these calculations are so obvious that only a few understand the principles standing behind the scene.

In the previous article Estimating Probability of Bitcoin Pullback in its Bullish Market we touched an interesting point worth exploring a bit further. Namely, the probability of Bitcoin close-price closing each day higher than a day ago days in a row. We had seen that in July 2021 Bitcoin moved and

In quantitative finance we are used to measuring direct linear correlations or non-linear cross-bicorrelations among various time-series. For the former, by default, one adopts the calculation of Pearson product-moment correlation coefficients to quantify a linear relationship between two vectors.

Let me kick off the series of QuantAtRisk’s podcasts Break into Finance. I address it to all of you who wish to join the financial industry but have no clue how to do it as well as to those of you who would like to make a change, improve your career, get better, and succeed within the industry.

They say that a journey of thousand miles commences with a single step. So, here you are, firm in your own resolutions or hesitating where to go. Graduated from a university or standing and trembling about next move in your life. Fired from one job or looking for another opportunity to seize.

With a myriad of new crypto-exchanges popping up every quarter, lots of newcomers to this fields can be overwhelmed by their number. Big names can quickly stand out if you filter the list according to daily trading volume or the total number of cryptocurrencies available for trading. Some offer

Placing limit orders for trade execution is both quite popular and handy method in (algo)trading. A trader expects that the executed price of his buy/sell trade will ideally match the one requested in his limit order. Unfortunately, depending on a momentary market/asset liquidity, the difference

They say that small fishes buy and sell driven by unstable waters but only big whales make the waves really huge. Recently, this quite popular phrase, makes sense when it comes to cryptocurrency trading influenced by sudden dives of the Bitcoin price. The strategies of buying and selling executed by

In 2020 Bitcoin delivered us another spectacular bull run. It was as impressive as the one we witnessed in 2017. The analysis of Bitcoin price time-series during its bull runs can uncover interesting results. By comparing a selected set of characteristics we could find some commonalities in trading.

Another day, another record. Today, at 17:35 GST+1, Bitcoin crossed U$33,000 in trading at Coinbase Pro exchange and did not fall sharply down. It took about 4.5 hours to accelerate from a psychological level of U$30k with more greed among investors rather than fear of bursting Bitcoin (second)

One of the most common problem encountered by all novice researches of the crypto-markets and (algo-)traders is knowing a list of all cryptocurrency pairs being actively traded at specific crypto exchange. This knowledge is a gateway to a vast research over correlations of crypto-assets, looking for

The Bitcoin’s 3rd halving was the most anticipated event this year. This a moment when a reward for all Bitcoin block miners is cut by half. It happens every 4 years or every 210,000 blocks on the Bitcoin blockchain. The previous two halving events took place in 2012 and 2016, respectively. Before

With a growing popularity of cryptocurrencies and their increasing year-over-year traded volumes, crypto algo-trading is a next big thing! If you study this market closely you will notice that it offers quick gains in much shorter unit of time comparing to stocks or FX. No wonder why a participation

Recent actions in WTI Futures pricing on Apr 20, 2020 caused my curiosity to have a deep look at intraday crude oil price time-series. With no surprise, I couldn’t find any free and effortlessly available dataset on the Internet. This is a common problem for lots of quants and data analysts:

A differentiation of the time-series is a common transformation used when we want to get a stationary time-series given a non-stationary one. The latter usually displays time-dependent relationships like trends, seasonality, quasi-cyclic patterns, and their Fourier power spectrum is characterised by

You can’t predict the future unless you have a crystal ball but you can predict an asset’s trading price in next time step if you have a right tool and enough confidence in your model. With the development of a new class of forecasting models employing Deep Learning neural networks, we gained

Hi Guys! I’m happy to kick off a new series of free video lectures devoted to Python’s library of pandas. Every week, I will be uploading something between 2 to 4 new videos especially crafted around practicalities of pandas library applied to financial data and their analysis and processing.

It would be too easy to kick off the series of lectures supplementing my Python for Quants ebooks starting from Machine Learning (ML) as an innovation. ML-based algorithms pay dividends when your problem is fairly well defined and data allow to capture the patterns where they exist. Deep Learning

There are various Python projects which require sorting but not the ones that employ a default alphanumeric functionality. We talk about manually specified order or human-order, in short. One of such examples is the case study presented below. Imagine that your risk system provides you with a list

In Financial Risk Management the most challenging part for quantitative modeling is, beyond any doubt, the Operational Risk (Ops Risk). It is defined as the risk of loss resulting from inadequate or failed internal processes, people and systems or from external events. This definition includes legal

There are not too many creative opportunities to leave a person applying for a quant role dumbfounded with the interview question directly related to his CV. First of all, we want to test his quant skillset, check his ability to read a code, analyse the model, listen to his judgement on the

It is my pleasure to deliver a long-awaited QaR ebook on the introduction to blockchain and cryptocurrencies with Python on April 15, 2018. In the book we will cover inter alia the fundamental aspects of blockchain in general; the craze around cryptocoins like Bitcoin, Ether, LiteCoin, etc.; their

By considering the same risk measure, ϱ, applied to two or more portfolios (credit loss distributions, profit-and-loss distributions, etc.) one desires to have a subadditivity property in place: ϱ(X1+X2)≤ϱ(X1)+ϱ(X2) i.e. meaning that two combined portfolios should never be more risky than the

When you come in contact with cryptocurrencies, e.g. Bitcoin (BTC), you quickly realise that there is no single price of BTC at any given moment. The reason is that Bitcoin is traded on different markets. It can be worth more on Coinbase exchange and less on Kraken exchange. In particular, the

IMHO, there is nothing more exciting these days than researching, analysing, and a good understanding of cryptocurrencies. Powered by blockchain technology, we live in a new world that moves fast forward as we sleep. In my first post devoted to that new class of tradable assets we have learnt how to

Welcome to a brand new era of “financial assets” – the crypto-assets. The impossible became possible. Yes, now you can trade cryptocurrencies: money that have been created in a virtual world with a physical impact onto our everyday cash-in-the-bank reality. The grande picture is still

Within our unique 2-Day Intensive Workshop in London, UK on Python for Algorithmic and Crypto-Currency Trading we dive into most recent and hot topics in algo-trading. We will cover and analyse a well explored world of classical assets (stocks, FX currencies) extended by trading techniques aimed at

After wonderful and rewarding 2-day workshop devoted to Python for Algo-Trading on March 4-5, it is my pleasure to announce a new, upcoming, on demand 2-Day Workshop on Machine Learning in Python for Finance (May 20-21, 2017). Since Machine Learning is the latest hottest topic covering different

The magnitude and importance of random numbers in finance does not have to be explained. We need them. Either it is an option pricing or a Monte Carlo simulation, random numbers are with us. However, we make a trade-off: the speed in their generation versus uniqueness. That is why a widely accepted

Conditional Value-at-Risk (CVaR), also referred to as the Expected Shortfall (ES) or the Expected Tail Loss (ETL), has an interpretation of the expected loss (in present value terms) given that the loss exceeds the VaR (e.g. Alexander 2008). For many risk analysts, CVaR makes more sense: if VaR is a

When we talk about correlations in finance, by default, we assume linear relationships between two time-series “co-moving”. In other words, if one time-series changes its values over a give time period, we seek for a tight correlation reflected within the other time-series. If found, we say they

A determination of peaks and troughs for any financial time-series seems to be always in high demand, especially in algorithmic trading. A number of numerical methods can be found in the literature. The main problem exists when a smart differentiation between a local trend and “global” sentiment

In the Operational Risk Management, given a number/type of risks or/and business line combinations, the quest is all about providing the risk management board with an estimation of the losses the bank (or any other financial institution, hedge-fund, etc.) can suffer from. If you think for a second,

The prediction of extreme rare events (EREs) in the financial markets remains one of the toughest problems. Firstly because of a very limited knowledge we have on their distribution and underlying correlations across the markets. Literally, we walk in dark, hoping it won’t happen today, not to the
