The risk-adjusted covered interest parity

The conventional covered interest rate parity has failed in modern FX markets. A new HKIMR paper suggests that this is not a failure of markets or principles, but a failure to adjust the parity correctly for relative counterparty and liquidity risk across currency areas. Specifically, FX swap rates deviate from relative money market rates due to counterparty risk and from relative risk free (OIS) rates due to liquidity risk. Correct adjustment helps to detect true FX market dislocations.

The dominance of price over value

Market prices reveal information about fundamental value indirectly. Private research produces information about fundamental value directly. Neither is a perfect indicator of fundamental value: the former due to non-fundamental market factors, and the latter due to limitations of private research. However, plausible theoretical research shows that overtime the information content of prices in respect to (known) fundamentals improves faster due to aggregation and averaging. When this happens investors rationally neglect their own fundamental research. This can erode information efficiency of the market and lead to sustained misalignments if the market as a whole misses key risks and value factors.

Selecting macro factors for trading strategies

A powerful statistical method for selecting macro factors for trading strategies is the “Elastic Net”. The method simultaneously selects factors in accordance with their past predictive power and estimates their influence conservatively in order to contain the influence of accidental correlation. Unlike other statistical selection methods, such as “LASSO”, the “Elastic Net” can make use of a large number of correlated factors, a typical feature of economic time series.

What made FOMC members hawkish or dovish?

An empirical analysis based on transcripts of the U.S. Federal Open Market Committee from 1994 to 2008 suggests that differences in committee members’ policy differences can partly be explained by differences in regional data, particularly unemployment rates. Also, personal background may play some role: FOMC members with experience in the non-financial private and public sectors have historically been more dovish.

The importance of differentiating types of oil price shocks

To assess the consequences of an oil price shock for markets it is important to identify its type. A new method separates oil supply shocks, oil market-specific demand shocks and global growth shocks. Supply shocks have accounted for about 50% of price volatility since the mid-1980s. Oil market-specific shocks drive a wedge between the growth of developed and emerging economies and hence matter for exchange rate trends. Global demand shocks to oil prices do not cause such a divergence.

Fed policy shocks and foreign currency risk premia

A new Federal Reserve paper suggests that non-conventional monetary policy easing “shocks” not only push foreign currencies higher versus the U.S. dollar, but also reduce the risk premia on foreign-currency cash and bonds. Non-conventional easing shifts the options-implied skewness of risk from dollar appreciation to depreciation, due partly to diminishing U.S. dollar funding pressure. The effects appear to be temporary, though.

Sticky expectations and predictable equity returns

New research documents that company earnings expectations of analysts have historically been sticky, plausibly reflecting that it takes time and effort to update forecasts. Such stickiness can explain two important anomalies of stock returns: price momentum and outperformance of high-profitability stocks. Indeed, these two anomalies have been correlated and stronger for stocks where analyst expectations have been stickier.

The illiquidity risk premium

The illiquidity risk premium is an excess return paid to investors for tying up capital. The premium compensates the investor for forfeiting the options to contain mark-to-market losses and to adapt positions to a changing environment. A brief paper by Willis Towers Watson presents an approach to measure the illiquidity risk premium across assets. The premium appears to be time-variant and highest during and pursuant to financial crises.

FX strategies based on real exchange rates

New empirical research provides guidance as to how to use real exchange rates for currency strategies. First, real exchange rates can serve as a basis for value-based strategies, but only if they are adjusted for key secular structural factors, such as productivity growth and product quality. Second, real exchange rates in conjunction with macroeconomic indicators can serve as indicators for the risk premia paid on currency positions.

The 1×1 of trend-following

Trend-following is the dominant alternative investment strategy. Its historical return profile has been attractive on its own and for diversification purposes. It is suitable for rising and falling prices, albeit not for range-bound and “gapping” markets. A basic trend-following algorithm is easy to build. Trend-following commands over USD300 billion in dedicated assets and a lot more are managed by informal trend-followers. The style is itself a major force of price trends, with no direct ties to fundamental asset value.
