So, imagine there is a big game where people buy and sell things called "stocks". These stocks are parts of different companies. Sometimes these companies make more money or do better than expected, so the price of their stocks goes up. That's good news for people who own those stocks because they can then sell them for more money. Today, some big companies like Sanofi, Union Pacific and Kirby did well and made more money than people thought they would. So their stock prices went up too. This made the people who owned those stocks happy because they could make more money from selling them. Read from source...

- The title is misleading and sensationalized. It implies that Sanofi had a strong performance and joined other big stocks moving higher on Thursday, but it does not mention the negative impact of currency effects on its earnings or the overall market downturn.
