Best Stock Market Indicator Update

We continue to receive requests for updates to the "Best Stock Market Indicator", which used to be a regular guest post from John Carlucci. Here is an update of the "Carlucci" indicator along with a summary of John's explanation on how he uses it.


As John described it: "The $OEXA200R (the percentage of S&P 100 stocks above their 200 DMA) is a technical indicator available on StockCharts.com used to find the "sweet spot" time period in the market when you have the best chance of making money."

Latest Indicator Position

According to this system, the market is now tradable and a signal to enter and continue all long trading. The OEXA200R is at 84% and all three secondary indicators are positive.

  • RSI is POSITIVE (above 50)
  • Slow STO is POSITIVE (black line above red line)
  • MACD is POSITIVE (black line above red line)

Carlucci Indicator

Background on the "Carlucci" Indicator

The OEXA200R is a metric used to assess the state of the market in order to make profitable trading decisions. That is, whether we are in a bull market, a bear market or transitioning from one to the other, as well as market volatility and risk within each of those situations. Historically, it has also given traders a clear early warning signal of impending serious market downturns and later safe re-entry points. While not intended as a day trading tool per se, it can certainly be used as background information by highly speculative traders. Simply put, the OEXA200R gives traders the ability to identify the most opportune conditions within which to execute their various long, short or hold strategies.

Definition of Terms:

"Tradable" refers to the point at which it is most advantageous to enter and continue long trading.

"Un-tradable" refers to the point at which it is advisable to exit all long positions that have not already automatically closed with a trailing stop loss. Please be aware that the OEXA exit points are not always timed at the exact top of any run up, that is impossible to predict. However, a trailing stop will follow the price to the highest point and close out as it falls from there, meaning most positions should have closed before the OEXA exit signal appears and thus should close at a point higher than at the exit signal.

Following a major market correction, the conditions for safe re-entry are when:

a) Daily $OEXA200R rises above 65%

And two of the following three also occur:

b) Weekly RSI rises over 50

c) Weekly Slow STO black line rises above red line

d) Weekly MACD black line rises above red line

Without the solid foundational support of two out of three Weekly secondary indicators, it is unsafe to trade even if Daily OEXA200R edges above the 65% line. The market is considered safely tradable as long as Daily OEXA200R remains above 65% and two weekly secondary indicators remain positive. Volatility and risk for long traders are relatively low. The trend is on their side.

Conversely, when Daily OEXA200R drops below 65% and/or two out of three weekly secondary indicators turn negative it, is taken as the conservative signal to exit all long positions, even if the previous Weekly OEXA is above 65%. Volatility and risk increase substantially. In the past, this has often been a "tipping point" condition presaging a substantial market drop.


On a Personal Note: The "Carlucci" indicator is certainly an interesting metric, although it can be quite volatile over extended periods of time. Thus we don't see it as suitable for trend-following strategies -- for example, buying/selling based on monthly moving averages, as in The Ivy Portfolio system. However, it is certainly worth considering as a tool for gauging market health.
