Market Volatility: Mean Reversion

Market Volatility: Mean Reversion

Markets found their way back to volatility, showing a couple of new patterns – including some sector preferences and a muted “risk-off” reaction.

"The most predicted selloff of all time."
James Bullard, President of the Federal Reserve of St. Louis

Market Volatility: Mean Reversion The world’s markets have been put to the test over the past week; U.S. equities moved solidly into the -10% “market correction” zone since the intra-day peak on January 26, 2018. The VIX Index was trading in the 40 range as of mid-afternoon Friday,1 levels not seen for 2½ years, since the correction of August 24, 2015.  U.S. equity markets showed some differentiation, however; declines in the 11 industry sectors of the S&P500 ranged from -4.4% (Utilities) to -11.2% (Energy), suggesting that there were both general and sector-specific forces at work:

Another feature of note: Treasury yields rose nearly to pre-rout levels immediately after the expected first-days pullback; the intra-day low yield of 2.65% on Tuesday, Feb 6 was followed by a rebound to 2.875% on February 8, rather than staying at a more “risk-off,” lower level.

Each market correction has its own characteristics; rationales fly freely when markets gyrate. Blame is put at the feet of slightly elevated wage growth; technical factors, including the S&P500 index breaching the 50-day and 100-day moving averages; short-volatility ETF liquidity; and equity valuations. Also worthy of consideration: the belated acceptance of a rising rate environment, which had been signaled years in advance by a carefully-communicating Fed. One thing is clear: After this past week, valuations are being rethought for several classes of assets.



U.S. Treasuries are direct debt obligations issued and backed by the "full faith and credit" of the U.S. government. The U.S. government guarantees the principal and interest payments on U.S. Treasuries when the securities are held to maturity. Unlike U.S. Treasury securities, debt securities issued by the federal agencies and instrumentalities and related investments may or may not be backed by the full faith and credit of the U.S. government. Even when the U.S. government guarantees principal and interest payments on securities, this guarantee does not apply to losses resulting from declines in the market value of these securities.

IMPORTANT INFORMATION: All investments involve risk, including loss of principal. Past performance is no guarantee of future results. An investor cannot invest directly in an index. Unmanaged index returns do not reflect any fees, expenses or sales charges.

Equity securities are subject to price fluctuation and possible loss of principal. Fixed-income securities involve interest rate, credit, inflation and reinvestment risks; and possible loss of principal. As interest rates rise, the value of fixed income securities falls. International investments are subject to special risks including currency fluctuations, social, economic and political uncertainties, which could increase volatility. These risks are magnified in emerging markets.
