The yield curve is an important thing to watch for if you are trying to understand what’s going to happen with the economy and the inverted yield curve usually means that we’re about a year from the next recession.

The Future of PaymentsMarch 2, 2019
Payments are building blocks of our society and we started transacting value long before we were able to read or write.

Cost of Living in PhuketJanuary 27, 2019
Thailand has been a popular destination for the remote workforce in the last decade, mostly because it can offer a good mix of warm weather, reasonable prices and welcoming culture.

Plotting Financial Data With Python: Efficient Frontier (N assets)November 25, 2018
We already have the efficient frontier script that we created in the previous post but it has one major limitation: it does not allow us to plot more than 2 assets. Plotting 2 assets is enough to see diversification in action but it’s not practical to have a portfolio that consists of 2 assets.
Plotting Financial Data With Python: Efficient Frontier (2 assets)November 21, 2018
The main idea behind the Efficient Frontier is that the overall risk (volatility) of a portfolio may not be equal to the sum of the risk of its components so some combinations are better than others. In this post we’re going to visualize the optimal weights of 2 given assets in a hypothetical portfolio.

As anyone would expect, such a phenomenon cannot avoid generating a lot of drama and controversy.
Plotting Financial Data With Python: Comparing ReturnsOctober 11, 2018
It’s hard to compare the returns on the given securities just by looking at their price history in absolute terms so we need to find a better way of comparing historical returns. One of the possible solutions is to adjust the whole data series in such a way that the first data point would be equal to some predefined number.
Plotting Financial Data With Python: VarianceOctober 6, 2018
Variance is an important indicator if you want to know the level of risk associated with a given security. It’s important to understand that past variance might not be a good predictor of future variance but most of the time it works and we don’t have other options anyway. Let’s create a script for displaying returns distribution, variance and standard deviation of any given security.
Plotting Financial Data With Python: HistorySeptember 30, 2018
Sometimes I need to plot some financial data and it might be tricky because most of the financial websites do not offer enough customization or they have a usage limitations unless you subscribe.
