Crossing A Flat 200-Day Average As Optimism Follows The Thrust

Jumping over a flat average

The S&P 500 finally closed above its 200-day average after a couple of months below. Because the decline was not that severe or long-lasting, the average was flat.

When the S&P has ended a streak below its 200-day average and that average was flat, its returns were quite a bit less positive than if the slope of the average was more negative. Across almost every time frame, the S&P was positive more often, by a greater amount, with less risk, and with more reward, when it crossed above a downward-sloping 200-day average.

Thrust, then optimism

A Zweig Breadth Thrust triggered early in January, and now we’re seeing some signs of returning optimism. When that has happened other times since 1970, stocks mostly kept grinding higher, though the next couple of months were choppy. In the short-term, returns were mostly good, but by two months later, the overall bias was negative, including 7 of the last 9 signals.

Overbought in a downtrend

The McClellan Oscillator for the Shanghai Composite has crossed above 50 while the index is still below its declining 200-day moving average.

According to the Backtest Engine, since 2003 that has led to a further gain for the Shanghai over the next month only 40% of the time, with an average return of -0.6%.

Longer-term thrust

Breadth momentum has been so positive for tech that the McClellan Summation Index has soared above +1250. This has led to negative returns for the XLK fund over the next 1-2 weeks, but a year later it was higher 95% of the time by an average of 16.3%.
