Broad Selling Pressure, but Not Enough to Tip the Scales

Breadth indicators, such as Advance-Decline Percent, measure the participation behind a move in the underlying index. Sometimes participation is so strong that it tips the scales and signals the start of an extended move. For example, 10-day EMA of SPX AD% triggered a bearish breadth thrust on February 25th and the S&P 500 extended lower. Subsequently, a bullish breadth thrust triggered on April 29th and the advance extended into early September. Downside participation was quite strong the last two weeks, but not enough to tip the scales and trigger a bearish breadth thrust. Let’s investigate.

AD% measures the percentage of net advances in an index (advances less declines divided by total issues). The chart below shows an example using the S&P 500. AD% is -80% when there are 50 advances and 450 declines ((50 – 450) / 500). This means 90% (450) of stocks in the S&P 500 declined. As we can see with the red shading on the chart below, AD% dipped to -80% or lower three times in the last ten days. There were 214 advances and 285 declines on Friday so AD% finished at -14.2% on Friday.

Daily AD% readings can be quite noisy with regular moves above +80% and below -80%. A string of such moves can provide a signal or we can apply a moving average for smoothing. The next chart shows a 10-day EMA of AD%, which I cribbed from Marty Zweig, who also used a 10-day EMA for his breadth thrust indicator. A move above +30% triggers a bullish breadth thrust, while a move below -30% triggers a bearish breadth thrust. As the chart below shows, there was a bearish thrust on February 25th and a bullish signal on April 29th.

Even with the -14.2% reading on Friday, a bearish breadth thrust did not trigger because the 10-day EMA did not break below -30% this week. This means the S&P 500 avoided a bearish breadth thrust, is above its 200-day, is short-term oversold and is trading near support from the September lows. Hmm…

The Setup to Anticipate the Breakout – XME Example

Chartists are often faced with a choice: wait for the breakout or anticipate using a mean-reversion setup. The Metals & Mining SPDR (XME) broke out of a bullish consolidation this week and the breakout signals a continuation of its long-term uptrend. Chartists keying off the mean-reversion setup could have anticipated the breakout and gotten the early jump. Let’s investigate.

Silver Crosses Turn Dull

There are fewer silver crosses in the major stock indexes and this shows less participation during the last leg higher. A silver cross occurs when the 20-day EMA crosses above the 50-day EMA. DecisionPoint took this concept on step further and developed breadth indicators based on the percentage of stocks with silver crosses. This is a great way to look under the hood and aggregate medium-term trend performance for each index. The chart below shows this indicator for four key indexes: $NDX, $SPX, $MID and $SML. I set the bullish and bearish thresholds at

Trend Composite Turns Fully Bullish for Verizon

Verizon (VZ) participated in the first leg up from late March to mid April, but then stumbled with a decline into mid June. This stumble, however, looks like a classic correction and the stock broke out with a strong move over the last six weeks. In addition, the TIP Trend Composite, which aggregates five trend-following indicators turned positive in early August. Let’s investigate further.

Four Stocks Poised to Drive Healthcare Higher

The Healthcare SPDR (XLV) is one of the strongest sectors in 2020. Even though it does not sport the biggest gain, XLV recorded a new high in July and some 80% of its components are above their 200-day EMAs. The new high points to a long-term uptrend and upside leadership, while the percentage of stocks above the 200-day EMA points to broad strength within the sector. Sector SPDRs, however, are only as strong as the sum of their parts (component stocks).

A Bollinger Band Breakout or the Dreaded Head Fake?

There were a number of Bollinger Band squeeze plays over the last two weeks and also a number of breakouts. These breakouts are bullish until proven otherwise, but chartists should also be aware of the head fake. In his book, Bollinger on Bollinger Bands, here’s how John Bollinger puts it: Traders beware! There is a trick to The Squeeze, an odd turning of the wheel that you need to be aware of, the head fake.

Knowing When to Add Risk and When to Reduce Risk

The S&P 500 is the most widely used benchmark for the US stock market and the 200-day SMA is perhaps the most widely used moving average. These two came together again in late May as the index crossed back above on May 27th. Today we quantify the performance of prior signals and show how a little smoothing can go a long way. Furthermore, a simple market timing mechanism can tell investors when to add risk and when to seek alternatives to stocks.

Timing S&P 500 Swings Using the Bullish Percent Index

The Bullish Percent Index is a breadth indicator that quantifies double top breakouts and double bottom breakdowns, Point & Figure style. Basically, this indicator measures higher highs (breakouts) versus lower lows (breakdowns). This makes it a great candidate to quantify underlying strength and weakness in the S&P 500. There have been three signals in the last few months and one triggered this week.

Big Biotechs Make a Big Statement

The two most popular biotech ETFs are leading the market this month and making big statements. Before looking at these two, note that they are quite different. The Biotech ETF (IBB) is dominated by large-cap biotechs with the top ten holdings accounting for over 50%. The Biotech SPDR (XBI), on the other hand, is a broad-based ETF with the top ten holdings accounting for less than 25% of the ETF.
