Sure, I'd be happy to explain this in a simple way!

You know how sometimes your teacher or parents might tell you that something is really good (like, "That's fantastic! You did really well!"), and other times they might say it's not so great ("Hmm, maybe we can do better next time.")? Wall Street analysts kind of do the same thing with stocks. They look at how a company is doing and give their opinions.

In this story:
- Some smart people (analysts) who watch many companies said some things about certain stocks.
- For example, one analyst said a stock named PLUG isn't so good right now and suggested people should sell it if they own it. They changed their mind because of something related to the company's business.
- Another analyst was also not very happy with another stock called RNG and thought it might do even worse in the future compared to what they expected before.

So, these analysts are telling us that they think these stocks might go down in price or do badly in the market. They're like a guide for people who invest their money into these companies' stocks. But remember, just like how your teacher or parents might change their mind about something, these analysts can also be wrong sometimes!

And that's what happened here! Some analysts changed their minds about some stocks they were watching and told others why they think those stocks aren't doing as well as before. Read from source...

Here are some potential criticisms and concerns about the provided article based on your guidelines:

1. **Inconsistencies**:
- The article mentions that RingCentral shares closed at $34.65 on Friday, but the suggested price target after the downgrade is $37.
- There's no mention of why the analysts changed their ratings or what new information led to these decisions.

2. **Biases**:
- The article primarily focuses on negative news (downgrades), which could create a biased perception for readers about the overall analyst sentiment towards these companies.
- It doesn't provide any context about other analysts' views, except for the explicit mention of "see how other analysts view this stock" in each section.

3. **Irrational Arguments**:
- The downgrades are presented factually but aren't analyzed or questioned. For instance, why might Terence Flynn have lowered his price target for Intellia Therapeutics by over 80%?
- No alternative viewpoints or counterarguments are provided to challenge the analysts' perspectives.

4. **Emotional Behavior**:
- The use of stock closures on Friday might evoke an emotional response in readers, as they likely closed their trading positions at significant losses due to these downgrades.
- The article doesn't provide any calming or balanced perspective; it only presents negative news that could agitate investors.
