Statistical remedies against macro information overload

February 4, 2017

“Dimension reduction” condenses the information content of a multitude of data series into small manageable set of factors or functions. This reduction is important for forecasting with macro variables because many data series have only limited and highly correlated information content. There are three types of statistical methods.The first type selects a subset of “best” explanatory variables (view post here). The second type selects a small set of latent background factors of all explanatory variables and then uses these background factors for prediction (Dynamic Factor Models). The third type generates a small set of functions of the original explanatory variables that historically would have retained their explanatory power and then deploys these for forecasting (Sufficient Dimension Reduction).

Debt-weighted exchange rates

January 28, 2017

Trade-weighted exchange rates help assessing the impact of past currency depreciation on economic growth through the external trade channel. Debt-weighted exchange rates help assessing the impact of past currency depreciation on economic growth through the financial channel. Since these effects are usually opposite looking at both simultaneously is crucial for using exchange rate changes as a predictor of economic and local market performance. For example, as a consequence of the financial channel many EM economies fail to benefit from currency depreciation in the way that small developed economies do.

Using SVAR for macro trading strategies

January 21, 2017

Structural vector autoregression may be the most practical model class for empirical macroeconomics. Yet, it can also be employed for macro trading strategies, because it helps identifying specific market and macro shocks. For example, SVAR can identify short-term policy, growth or inflation expectation shocks. Once a shock is identified it can be used for trading in two ways. First, one can compare the type of shock implied by markets with the actual news flow and detect fundamental inconsistencies. Second, different types of shocks may entail different types of subsequent asset price dynamics and may, hence, be a basis for systematic strategies.

The power and origin of uncertainty shocks

January 14, 2017

Uncertainty shocks are changes in beliefs about probabilities. They are perhaps the most powerful driver of financial markets. Uncertainty comes in various forms, such as macro uncertainty, firm-specific uncertainty and uncertainty about others’ beliefs. However, empirical and theoretical research suggests that different types of relevant uncertainty shocks have one common dominant origin: updated beliefs about disaster risk. Hence, when markets give greater probability of downside tail risks, all sorts of uncertainty would rise, with a profound impact on macro trading strategies, whether they are directional or based on relative value.

Volcker Rule and liquidity risk

January 7, 2017

The Volcker Rule has banned proprietary trading of banks with access to official backstops. Also, market making has become more onerous as restrictions and ambiguities of the rule make it harder for dealers to manage inventory and to absorb large volumes of client orders in times of distress. This increases liquidity risk, particularly in market segments with longer turnover periods, such as corporate bonds. A new empirical paper confirms that the Volcker Rule has indeed reduced corporate bond liquidity and aggravated the price impact of distress events, such as significant rating downgrades.

Inflation: risk without premium

December 31, 2016

Historically, securities that lose value as inflation increases have paid a sizable risk premium. However, there is evidence that inflation risk premia have vanished or become negative in recent years. Macroeconomic theory suggests that this is related to monetary policy constraints at the zero lower bound: demand shocks are harder to contain and cause positive correlation between inflation and growth. Assets whose returns go down with higher inflation become valuable proxy-hedges. As a consequence, inflation breakevens underestimate inflation. Bond yields would rise disproportionately once policy rates move away from the zero lower bound.

Improving asset return forecasts with wavelets

December 23, 2016

Time series that are used for forecasting asset returns can carry information on trends of different persistence. Therefore, frequency decomposition of standard signals based on wavelets can improve and expand potential predictors. Similarly, asset returns can be decomposed into parts of different persistence. These can be forecast separately and summed up eventually. This “sum-of-parts” method seems to improve forecast accuracy because its aligns predictors and return trends and helps separating signal from noise.

The drivers of commodity cycles

December 17, 2016

Demand shocks have been the dominant force behind non-oil commodity price cycles, according to a 145-year empirical analysis. They have been linked to global recessions or recoveries and displayed persistent effects of 10 years or more. The second most import driver has been so-called “inventory shocks”, which have been less long-lived. Supply shocks have not played an important role in driving long-term price deviations of most commodities. They were mostly commodity-specific and transient.

Credit market herding and price distortions

December 10, 2016

Corporate credit markets have historically been especially prone to herding. The main drivers of herding have been past returns, rating changes and liquidity. Sell herding has been particularly strong and flows have been disproportionate after very large price moves. Herding can be persistent and lead to significant price distortions. Non-fundamental price overshooting is a valid basis for profitable contrarian trading strategies.

Inflation differentials and equity returns

Inflation differentials and equity returns

There is evidence that equity markets fail to adjust to persistent cross-country shifts in inflation in a timely and efficient manner. While equity investors focus on tracking firm-specific price effects and cash flows, they seem to pay less attention to aggregate local inflation and appear sluggish in adjusting long-term discount factors across countries. Since equity is a long duration asset even small calibration errors in discount factors have a large impact. Empirically, real equity returns in lower-inflation markets tend to outperform those in higher-inflation markets. No such effect can be found in fixed income markets.
