Two important numbers that measure how much things cost are going to be looked at this week. Some people think these numbers will show that prices are not going up too fast anymore. If that happens, it could make investors happy and the stock market might go up. But we don't know for sure yet, so everyone is waiting and watching. Read from source...

1. The article starts with a vague and unclear headline that does not provide any specific information about the main topic or focus of the article. It seems to imply that Nasdaq and S&P 500 are set for a weaker open due to inflation data, but it does not explain how or why this is the case. This creates confusion and uncertainty for the reader who wants to understand the market dynamics and trends.
2. The article then proceeds to provide some background information about the indices and their performance on Monday, but it does not connect this information to the main topic of inflation data. It seems like a filler content that does not add much value or relevance to the reader who is interested in the inflation impact on the market.
3. The article quotes Yardeni Research as an expert source, but it does not provide any context or credibility about this firm or its track record. It also does not mention any other sources or opinions that might contrast or support the view of Yardeni Research. This creates a one-sided and biased presentation of the information that lacks balance and objectivity.
4. The article ends abruptly with an incomplete sentence, leaving the reader wondering what the author meant to say or imply. It seems like there was some text cut off or missing from the original source. This creates a poor impression of the quality and professionalism of the writing and editing process.
