Okay, imagine you're in a big library full of stocks (companies).

1. **Smartsheet** (SMAR) - One expert, John Difucci, who knows about many stocks, changed his mind. Before, he thought SMAR was a great stock to buy (he said "Buy"), but now he thinks it's okay just to keep instead of buying more or selling (he says "Neutral"). The price of SMAR ended at $56.02 on Friday.

2. **Agilon Health** (AGL) - Another expert, Constantine Davides, also changed their mind about AGL. They used to think it was a good stock to buy (they said "Market Outperform"), but now they think it's okay just to keep (they say "Market Perform"). The price of AGL ended at $1.84 on Friday.

3. **Celanese Corporation** (CE) - This time, an expert named John McNulty changed their mind about CE too. They used to think it was an alright stock (they said "Market Perform"), but now they think it's a stock you should sell or not buy more of (they say "Underperform"). The price target (the highest price the stock might reach) also went down from $138 to $76, and the price ended at $84.80 on Friday.

For each of these stocks, other experts might have different opinions, so you should always listen to many people before making a decision about what stocks to buy or sell. Read from source...
