Market Trend Charts

The market's trend can be identified by observing the position and direction of the moving averages on the daily, weekly, and monthly charts below as well as the behavior of the Price Momentum Oscillator (PMO).

Daily Trend Analysis

This daily chart should be reviewed every day. If the 20-day EMA (green) is above the 50-day EMA (purple), the intermediate-term trend is bullish. If the 50-day EMA (purple) is above the 200-day EMA (blue), the long-term trend is bullish. Changes in the PMO's direction may signal an upcoming short-term trend change. When the PMO crosses its red signal line it is even stronger evidence of a significant change in trend.

Weekly Trend Analysis

This weekly chart should be reviewed at the end of each week. If the 17-week EMA (green) is above the 43-week EMA (purple), the long-term trend is bullish. Changes in the PMO's direction is even stronger evidence of a change in the long-term trend.

McClellan Oscillators

The McClellan Oscillator reflects the short-term strength and direction of the market. Readings above zero are bullish, readings below zero are bearish. Readings above +100 or below -100 are extreme and often signal a market turn.
The McClellan Summation Index provides a longer-term view. In general, if the index is rising it is bullish and if it is falling, bearish. Typically, the index ranges from -1000 to +1000.
In the bottom panel are the two different EMAs of the (invisible) Advance/Decline ratio that are used to calculate the McClellan Oscillator. The red 39-day EMA is called the "5% Index" and the blue 19-day EMA is called the "10% Index." If both the 5% and 10% Indexes are positive, the market is strengthening. If they are both negative, it is weakening.
