As Markets Swing, Momentum Can Be Deceiving

Weekly commentary overview

  • Stocks experienced several violent reversals last week before finishing strong. Stocks continue to find support in an old friend: central bank accommodation, most recently from the Bank of Japan.
  • Despite this most recent spike to the proverbial central bank “punch bowl,” we are likely to see continued abrupt swings in financial markets.
  • This is particularly true in those areas that seem crowded, i.e., are particularly expensive.
  • Thus, in the prevailing environment of heightened volatility, momentum remains an unpredictable theme.

Central banks to the rescue…again

Stocks experienced several violent reversals last week before finishing strong. The Dow Jones Industrial Average climbed 2.32% to end the week at 16,466, while the S&P 500 Index rose 1.78% to 1,940 and the Nasdaq Composite Index advanced 0.49% to 4,613. In fixed income, the yield on the benchmark 10-year U.S. Treasury fell from 2.05% to 1.92% as its price rose.

Stocks continue to find support in an old friend: central bank accommodation, most recently from the Bank of Japan (BoJ). Despite this most recent spike to the proverbial central bank “punch bowl,” we are likely to see continued abrupt swings in financial markets. This is particularly true in those areas that seem crowded, i.e., are particularly expensive. Thus, in the prevailing environment of heightened volatility, momentum remains an unpredictable theme.

Less than zero

In a pattern similar to that seen in the previous week, stocks shrugged off an uneven start to finish strong. Early on, equities were contending with several headwinds: disappointment with the Federal Reserve’s January statement, soft economic data and a mixed start to the fourth-quarter earnings season in the U.S. Headline gross domestic product was a bit soft, although consumption was solid, and the durable goods report was weak. Adding to the pessimism, with over 20% of S&P 500 companies having reported, revenue growth is flat and earnings are down 3.7%.

Still, stocks benefited from the announcement of more aggressive stimulus from the BoJ, which has now followed the European Central Bank (ECB) toward an unconventional negative deposit rate. The BoJ lowered its deposit rate to -0.1% from 0.1%, while maintaining its 80-trillion-yen-per-year asset purchase program. Japanese equities surged on the news, the yen declined sharply and 10-year Japanese government bond yields fell below 0.10%.

Europe also rallied, gaining more than 2% on Friday to finish the week with modest gains. In addition to the tailwind from the BoJ announcement, European stocks are also benefiting from a solid start to earnings season. While still in the early stages, growth in earnings per share stands at 12% year-over-year and sales growth is up by 6%. Roughly 60% of both earnings and revenue announcements have exceeded expectations. This is above the historical average and an improvement over the previous quarter. The stronger undertone in the market has helped to stabilize flows, with European equity exchange traded funds notching inflows for the week.

The synchronized movement of stocks and oil is also persisting, although the reason why is not quite clear. By week’s end, crude had staged a mini-bull market over just seven trading days.

In a world of higher volatility, lower liquidity and economic uncertainty, investors can expect acute market swings to continue.

Reversal of fortune

Earlier in January, stocks fell faster than any deterioration in fundamentals would seem to warrant. Now, the opposite has occurred: This latest rally is more a function of a shift in sentiment than an improvement in fundamentals. Two of the world’s major central banks have pushed policy rates deeper into negative territory, reinforcing the notion that zero is no longer the lower bound on how low rates can fall.

Still, although the BoJ was successful in providing a boost to markets, investors need to have modest expectations regarding what central banks can accomplish from here. After multiple rounds of quantitative easing and other unconventional programs, liquidity-driven rallies are likely to prove more fleeting that those of the past five years. Case in point: China. On Thursday, the People’s Bank of China conducted its biggest daily liquidity operation in three years. Nonetheless, Chinese equities remain under pressure. While Chinese stocks rebounded on Friday, as of Thursday’s close, Shanghai A-shares were down 25% year-to-date.

In part, the recent bounce in risky assets can be attributed as much to a reversal of crowded positions as to negative interest rates in Europe and Japan. For example, much of the recent spike in oil has been a function of a crowded trade reversing itself. Hedge funds have been shorting oil at record levels through both futures and options, but are now covering those positions. Meanwhile, inventories and production continue to rise. In other words, not much has changed about oil, yet the price swings based on investor behavior.

The sharp reversal in stocks and oil illustrates an important feature of this market: In a world of higher volatility, lower liquidity and economic uncertainty, investors can expect acute market swings to continue. Although stocks and oil have rallied over the past week, several former momentum plays are producing disappointing results. Apple is contending with a slowdown in iPhone sales while Amazon was hit after missing earnings. And prior to Friday’s rally, the once mighty biotech sector had declined roughly 20% in January alone. The key message for investors: Proceed with caution when chasing momentum themes.
