What is the Consumer Price Index(CPI)? The Consumer Price Index (CPI) is a measure of the change in prices paid by consumers for a basket of goods and services.

How Investor Sentiment Changes and Why It Matters

2. Clusters and bubbles: centered around cryptocurrency mania

3. Evidence of herd mentality: Analyzing analysts and reactions to articles

We often observe extreme reactions to analysts issuing bubble warnings or neutral articles, as well as opinions predicting that already overvalued stocks or sectors will still rise.


If you see any of the above evidence in any sector/stock market at the moment, you should take it as conclusive evidence that there is a severe skewing of the crowd in that sector/stock market.

The process of bubble formation is often filled with excitement, but the key is to remain calm and collected.


This is because when the bubble bursts, everyone is in competition with each other. At that point, you can lose a lot of money if you don't keep your cool.


Therefore, if you believe that a particular industry is entering a bubble phase, instead of reacting to it, you need to keep a cool head and revisit your investment strategy. This will help you minimize your losses when the bubble bursts.
