A big research company called Ned Davis Research (NDR) said that the stock market is doing really well and could keep going up until 2027. They think this because the shape of the market's growth looks good and they compare it to other times when the market did well for a long time. Some people are worried about how much money technology companies are worth, but NDR says things are still okay. Read from source...

1. The title is misleading and sensationalized, implying that the bull rally is only halfway through and could continue until 2027. This statement is based on a single research report from Ned Davis Research, which may not be representative of the overall market sentiment or historical patterns. A more accurate title would be "Stock Market Bull Rally: One Perspective From Ned Davis Research".
2. The article cites the average length of a secular bull market (1,105 days) without providing any context or source for this data. This makes it difficult to verify or compare with other studies or periods in history. A more robust analysis would include factors such as interest rates, inflation, economic growth, corporate earnings, and valuations, which may influence the duration and direction of the market cycle.
3. The article mentions Jeremy Siegel's concerns about tech stock valuations but does not provide any counterarguments or balanced perspectives. This creates a one-sided narrative that favors the bullish outlook from Ned Davis Research without acknowledging potential risks or challenges. A more fair and informative approach would be to include both sides of the debate and weigh the pros and cons of investing in tech stocks at these levels.
4. The article ends abruptly with a quote from John Higgins, who has a different opinion on the market outlook. However, it does not explain why his forecast is relevant or how it relates to the main topic of the article. This leaves the reader confused and unsatisfied, as they are not given any insight into the implications or consequences of Higgins' views for the bull rally scenario. A better way to conclude the article would be to discuss how his predictions might affect the validity or applicability of Ned Davis Research's findings, and what investors should do in response to this uncertainty.
