Benford’s Law Suggests Bitcoin’s Price Manipulation

29.September 2020

Bitcoin is quite a controversial topic among the public. Many are interested in the blockchain technology or trade the cryptocurrencies , but the Bitcoin also has many opponents. Most frequently, Bitcoin is criticized for its volatility or a lack of supervision; some even call the Bitcoin a fraud. Yet many argue that blockchain is transparent. Novel research by Peterson examines the price manipulation using Benford’s law and a linkage to the anecdotal evidence of known manipulation. In theory, the distribution of leading digits in numerical data should follow the Benford´s law and any significant deviations usually signal a fraud. According to the results, in the history of bitcoin prices, several frauds were detected. The results have important implication for the Bitcoin; therefore, this research is probably a must-read for anyone interested in cryptocurrencies.

First-Half Month Cash-Flow News and Momentum in Stocks

24.September 2020

Stock prices react to the new information that investors continually receive from many sources. There are some major events, which are commonly connected with a new piece of information and subsequent reactions of investors. For example, quarterly earnings-announcements are the cause of the post-earnings announcement drift or PEAD. According to the PEAD, prices tend to continue to drift up (down) after positive (negative) news. But news related to quarterly announcements is not the only important information. A novel research paper written by the Hong and Yu explores implications of the month-end reporting, analyst revisions and management guidance that are coming to market usually in the first half of each month and are also connected with drifts that offer practitioners profitable opportunities.
