The Stock Market is Flashing a 'Buy' Signal Thanks to Indicators With a Near-Perfect Track Record

A widely-watched stock market indicator is signaling a strong buying opportunity as more stocks participate in the ongoing rally. The McClellan Summation Index, a tool used by technical analysts to measure market breadth, has experienced a sharp rise, suggesting further gains for the S&P 500. Dean Christians, a senior research analyst at SentimenTrader, believes that this upward shift in the McClellan Index is an especially reliable predictor of future stock market performance.

The McClellan Summation Index is a popular measure that tracks the number of stocks moving in a given direction within a particular index, such as the S&P 500. When the index rises, it indicates that more stocks are joining the market rally, and market breadth—how widespread the gains are—improves. On the other hand, a falling McClellan Index suggests deteriorating market breadth or a general decline in stock prices. In essence, this measure is used by analysts to get a sense of how stocks beneath the surface of an index are performing, even if the index as a whole is rising or falling.

‍

Historically, when the McClellan Summation Index experiences a rapid rise, it has often been followed by further stock market gains. Specifically, when this index climbs from below 100 to over 1,000, stocks have tended to continue rising over the next year with an accuracy rate of 96%. Analysts see this as a strong signal that more gains are likely to follow. Even more compelling, when this signal occurs while the S&P 500 is trading within 2% of a significant high, the indicator has proven to be 100% accurate in predicting additional upward movement. On Monday, the indicator flashed such a signal, suggesting that the market may be poised for further gains.

‍

Christians emphasizes that this particular signal is especially noteworthy because it goes beyond the usual upward drift of stocks over time. The market tends to rise in the long run, but the McClellan Summation Index’s rapid improvement gives a more targeted forecast, suggesting the potential for substantial gains in the near future. The implication is that the current rally may not only continue but also broaden, with more stocks contributing to the overall rise.

On Tuesday, the S&P 500 gained 14.36 points, or 0.3%, closing at 5,732.93, which marked its 41st record close of 2024. Similarly, the Dow Jones Industrial Average added 83.57 points, or 0.2%, to finish at a record-high 42,208.22, according to data from Dow Jones Market Data. Meanwhile, the Nasdaq Composite climbed 100.25 points, or 0.6%, to close at 18,074.52, although it remains more than 3% below its all-time high reached in July.

‍

The McClellan Summation Index is a popular tool in technical analysis because it provides insight into the overall health of the market. Market breadth is a crucial concept for technical analysts because it can reveal the true strength of a rally or sell-off. A rally driven by a broad range of stocks is generally seen as more sustainable than one led by just a handful of large companies. Conversely, if only a small number of stocks are pushing an index higher while the majority are stagnant or declining, the rally may be vulnerable to a reversal.

‍

In this case, the McClellan Summation Index is suggesting that the current rally is supported by a growing number of stocks, indicating a broad and healthy advance. The fact that the index has surged above the 1,000 level further strengthens this positive outlook. Historically, such rapid improvements in the index have been followed by substantial stock market gains, and there is reason to believe that this trend will hold true in the current environment.

‍

Christians notes that while no indicator is perfect, the track record of the McClellan Summation Index is impressive, particularly when it comes to predicting future gains in the S&P 500. The fact that the signal is flashing now, with the S&P 500 near record highs, makes it all the more compelling. Investors and analysts alike will be watching closely to see if the market continues to follow this historical pattern.

‍

In summary, the McClellan Summation Index is pointing toward further gains for the stock market, particularly the S&P 500. With market breadth improving and more stocks joining the rally, this indicator has historically been a reliable predictor of future gains. As the S&P 500 and other major indices continue to set new records, the signal from the McClellan Index suggests that the rally may have further to run, providing a bullish outlook for the months ahead.
