The Hierarchy of Stock Market Losses (A Wealth of Common Sense) Ben Carlson explains how people may lose money in the stock market differently – this depends on if they’re in developed markets, emerging markets, or just individual stocks.

It might be hard to trade Trump’s erratic decisions –but a bunch of investors have made a fortune from his tweets. The question is whether they have used insider information. Plus, there could be an unbeatable model to predict fund performance and no one has taken much notice.

The Best Predictor of Stock-Fund Performance (Morningstar) Turns out buying stocks held by successful funds is a reliable trading strategy for success.

“There Is Definite Hanky-Panky Going On”: The Fantastically Profitable Mystery of the Trump Chaos Trades (Vanity Fair) Investigates a number of large e-mini trades on the S&P500, often made right before the market closes and strangely right before a big geopolitical market shaker. Argues that this could be a case of insider trading and calls for heavier regulatory watch.Gulp.

We feature a paper looking at utilising machine learning in predicting crisis and why oil modelling remains robust.

Predicting Bank Distress in the UK with Machine Learning (Suss, Treitel) Looks at the benefits of machine learning techniques for providing regulators with a warning of firm distress. This gave an approach that is better aligned to help intervene ahead of failure.

Refining the Workhorse Oil Market Model (Zhou) Paper makes adjustments to previous work which has a model considered as the go-to for analysis of global oil markets. The 5 refinements he tries  had no effect on the substantive conclusions made – so the original model is still the one to use.

Value, Momentum and Carry – Is It Time for Equity Investors to Switch? (In the Long Run) For the active investors, value factors may offer a better risk reward profile, but, given the individual stock volatility dispersion, a market neutral defensive factor model, along the lines proposed by AQR, may deliver the best risk adjusted return of all.

A number of insightful pieces exploring how tech and machine learning in particular are breaking into finance. But models aren’t always perfect – mispricing risk can lead to a chain reaction and a downturn.

World Wide Currency (VOX EU) Is it possible to introduce a globally recognised electronic currency in the future alongside the national currencies? Researchers test this idea with a two-country model and conclude that it’s theoretically doable. Although for monetary policymakers, there’s certainly so much more to do to get them prepared for this futuristic trend.

A Volatility Smile-Based Uncertainty Index (Central Bank of Brazil) Introduces a new index to measure uncertainty: the “Volatility Smile-Based Uncertainty” (VSU).

Ten Applications of Financial Machine Learning (SSRN/Cornell University) Explores how the core of machine learning – studying past data to predict future outcomes – can be revolutionary for the financial services industry. However, it also warns that machine learning tools are vulnerable to input selection biases and that can lead to undesired consequences.

Perceiving Risk Wrong: What Happens When Markets Misprice Risk? (Bank Underground) Risk perceptions are extremely subjective and hard to quantify. This paper examines how overpricing and underpricing market risks can both eventually lead to an economic downturn in the manner of a chain reaction.
