Donation to Human Rights Foundation (hrf.org) and Stop Human Right Violation

Since the Hong Kong protest began, Hong Kong has suffered a human rights issue. Some Hong Kongers were killed, a female teenager claimed that she was raped, numerous protestors were unfairly treated after they were caught, but none of the police officers have been punished so far. Since I was born, I knew there was a human rights issue in this world, but I didn't realize that was a serious problem and how horrible it was until I witnessed this issue happening in Hong Kong.

When I was 16, I was deeply immersed in financial trading. I was focusing on finding patterns, learning how to make money through trading, and seldom caring for other people. Some readers who are now reading this article may be similar to me. Probably, you want to change your destiny by making more money. I don't think it is wrong because I do it too. However, apart from making money, I think caring about this world, caring about society, and caring about how other people live are also essential.

In 2018, the world marks 70 years since the adoption of the Universal Declaration of Human Rights. Human Rights Watch highlights some of the rights challenges that captured the world’s attention this year, illustrating the struggle to secure human rights is far from over.

There are some ways to stop this disaster. By raising awareness and letting more people know this, I believe this issue can disappear in the future. Every step can make a real difference.

Deflated Sharpe Ratio can reduce false discovery

Introduction With the recent advent of large financial datasets, machine learning, and high-performance computing, analysts can backtest millions of alternative investment strategies. Backtest optimizers search for combinations of parameters to maximize a strategy's simulated historical performance, leading to backtest overfitting. The performance inflation problem goes beyond backtesting. More generally, researchers and investment managers tend to report only positive results, a phenomenon is known as selection bias. Failure to control the number of tests involved in a given finding can lead to overly optimistic performance expectations. The Deflated Sharpe Ratio (DSR) corrects for two major sources of performance inflation: selection bias under multiple tests and non-normally distributed returns . By doing so, DSR helps separate legitimate empirical results from statistical deception. Backtesting is a good example. Backtesting is a historical simulation of how a particular inv

Alternative Sector Classification Methods

Abstract This paper offers two alternative sector classification methods in order to classify companies more accurately. Introduction During the early 1900s, various departments of the US government initiated research and studies on the various industries and their different functions. Due to the lack of set standards, each department ended up using its own methodology. Consolidating information across multiple sources became a challenge. The Standard Industrial Classification (SIC) was hence proposed as a uniform classification system, aimed to represent major industries, sub-class and specific function/product, and was formally adopted in 1937. However, SIC was facing a challenge because of the change in the economic environment. After that, the Global Industry Classification System (GICS) was launched by Standard & Poor's (S&P) and Morgan Stanley (MSCI) in August 1999. The standard provides a comprehensive, globally consistent definition of economic sectors and industr
