Cabot Market Timing Indicators

Here are explanations of our primary market timing indicators, which are discussed in every issue of the Cabot Growth Investor.

The Cabot Trend Lines

The Cabot Trend Lines are our unique way of determining the long-term trend of the stock market. As long as both the S&P 500 Index and the Nasdaq Index fluctuate above their respective trend lines, we consider the market to be bullish. If both indexes are below their trend lines, we are in a bear market.

The Cabot Trend Line for each index is the 35-week moving average.

Using the trend principle, we can never be on the wrong side of the market for very long. And once the new trend forces us onto the correct side of the market, the probabilities favor a continuation of the current market trend.

The Cabot Tides

We use five different market indexes to help us determine the overall intermediate-term direction of the stock market. They are: S&P 500, NYSE Composite, Nasdaq Composite, S&P 600 Small Cap and the S&P 400 MidCap.

The market is considered to be advancing on an intermediate-term basis if at least three of these five indexes are advancing. And contrarily, the market is deemed to be declining if at least three of these five are declining.

To derive intermediate-term signals, we compare each index to its own 25-day and 50-day moving averages. If the index is standing above the lower of these two moving averages, and that lower moving average is itself advancing, then this index is bullish. Otherwise, it’s safe to assume the intermediate-term trend for this index is down.

Probably the most important advantage of using this moving average approach in timing the market is that you are guaranteed to catch every major market advance while avoiding every major market decline. This is the nature of a moving average. But there is a cost. It’s the opportunity lost in the first few weeks of a new advance. And it’s the small penalty you must pay for getting out of the market quickly when the market changes its mind soon after a new buy signal is given. For example, a new buy signal could quickly turn into a sell signal if the market turned weak enough to drop the index below its lower moving average. If that happens you should quickly turn defensive again and start thinking about the preservation of your capital instead of trying to make big gains in a falling market.

The Two-Second Indicator

The Two-Second Indicator is so named because that’s how long it takes to read: Just two seconds, every day. Specifically, this indicator measures the number of securities on the NYSE reaching new annual (52-week) price lows on any given day. This data is readily available in most major newspapers, though we use the data from The Wall Street Journal.

The Two-Second Indicator’s specialty is detecting market tops. When the number of daily new lows on the NYSE is greater than 40 while the major indexes are rising to new peaks, look out! It’s telling you that, internally, sellers are in control of most stocks, and the indexes are masking this weakness. We call this the Leaky Boat Syndrome, where, on the surface, things look fine, but in reality you’re taking on water! It’s the same story when new lows expand to more than 40 just as the indexes come down from their peaks—again, not a good sign.

However, if new lows expand to greater than 40 after the indexes are five days or longer off their peaks, then it’s not as big a deal; in this case, the Two-Second Indicator is simply telling you the market is entering a correction. This correction could be deep, and thus you should still practice caution. But the chances that the market is entering a real bear market at that point are unlikely.

Finally, when new lows are less than 40 day after day, that’s a sign of a healthy, robust market—the buyers are firmly in control of most stocks. Overall, it’s a simple indicator, but we’ve learned that the simplest indicators are often the best, and the Two-Second Indicator certainly fills that bill.
