A stock market analyst from a big bank says not to worry if the prices of some stocks seem too high. He thinks the market will keep going up if there are no big changes like interest rates or inflation going up suddenly. He says it's best to pick stocks that are doing really well and making a lot of money to put in your portfolio. This is because these stocks will likely keep doing well and have high prices for a longer time. Read from source...

### Inconsistencies:
- The author mentions "an 8% overvaluation is no reason to get bearish", yet later implies that without a sudden increase in interest rates, unemployment, or inflation, the stock market's upward trend should continue, even if it is overvalued. These statements are inconsistent. If the market is overvalued, there is a reason to be bearish, regardless of whether there are sudden changes in interest rates, unemployment, or inflation.

### Biases:
- The article has a clear positive bias towards the stock market, with statements like "this advice comes from the portfolio-strategy group at Piper Sandler, led by Chief Investment Strategist Michael Kantrowitz", which suggests that the author agrees with Kantrowitz's viewpoint. The author also doesn't provide any counterarguments or dissenting opinions, further indicating a positive bias.

### Irrational Arguments:
- The statement "An 8% over-valuation is no reason to get bearish" is an irrational argument. Overvaluation is a strong reason to be bearish, as it indicates that the market is currently pricing stocks higher than their intrinsic value. This situation is unsustainable, as the market will eventually correct itself, leading to a decrease in stock prices.

### Emotional Behavior:
- The author's decision to use the word "sweat" in the title, and the tone of the article, suggest an emotional response to the market's current state. This emotional behavior is unhelpful in making informed investment decisions, as it can lead to impulsive and irrational actions.

Overall, the author's inconsistencies, biases, irrational arguments, and emotional behavior make this article a weak and unreliable source of information for investors.
