Over the first third of 2014, MDY’s adjusted closing share
price rose to $246.84 from $243.54, a gain of $3.30, or 1.36 percent.
Meanwhile, SPY rose to $188.31 from $183.88, a gain of $4.43, or 2.41 percent,
and IJR fell to $107.13 from $108.82, a loss of -$1.69, or -1.55 percent.
MDY is the 11th of 13 ETFs featured in a J.J.’s Risky
Business blog series this month. Basically, I have been looking at each
ETF with both eyes fixed on its Coppock guide, as was the case in “SPY Coppock Guide: Away From Bullishness, Toward
Nonbullishness as of March 31, 2014.” The Coppock guide, aka either the
Coppock curve or the Coppock indicator, is a long-term indicator of price
movements in major stock-market indexes calculated on the basis of monthly
data.

Edwin S. Coppock built his long-term guide not to flash both
bullish and bearish signals but to generate only bullish signals. However, I
employ it to produce either bullish or nonbullish signals. It is extremely
important to keep in mind that a nonbullish signal is not equivalent to a bearish signal in the context of the guide.
I anticipate MDY may rise after a bullish signal and expect
it might do anything following a nonbullish signal (i.e., trade higher, lower
or sideways).

The MDY Coppock guide’s initial bullish signals collectively
have been almost perfect in forecasting the future upward movements of the ETF
on monthly closing bases. In 15 cases since July 1997, these signals have been correct
on 14 occasions, or 93.33 percent of the time, and incorrect on one occasion,
or 6.67 percent of the time.
The latest initial bullish signal flashed in January, sandwiched
between initial nonbullish signals generated in December and February.
Accounting for the one-month lag in the confirmation of any signal, MDY’s
closing share price advanced to $250.57 in March from $249.71 in February,
which constitutes bullish action.

The MDY Coppock guide’s initial nonbullish signals
collectively have compiled an interesting track record since July 1997. As
customary, it is important to keep in mind a nonbullish signal is not equivalent to a bearish signal in
the context of the guide. Following 15 initial nonbullish signals over the
years, the ETF’s share price on monthly closing bases fell on nine occasions,
or 60.00 percent of the time, and rose on six occasions, or 40.00 percent of
the time.
The most recent initial nonbullish signal was produced in February,
when MDY’s closing share price was $249.71. Factoring in the one-month lag in
the confirmation of any signal, the ETF’s closing share price declined to $246.84
in April from $250.57 in March, which constitutes nonbullish action.
Intriguingly, the change in market participants’ mood
between last year and this year was indicated first not by the behaviors of
either SPY, a proxy for large-capitalization equities, or IJR, a proxy for
small-cap issues, but by the performance of MDY, a proxy for mid-cap stocks.
