Some people trade things called stocks, gold, and bitcoin. On Friday, they were unsure about what to do because they got mixed messages from companies' earnings reports (how much money they make) and data on how expensive it is for businesses to make stuff (producer inflation). Bitcoin lost a lot of value because a new type of bitcoin investment was allowed. Gold, which was expected to lose value, became more valuable instead. The stock market didn't move much that day because people were confused and waiting for clearer signals. Read from source...

- The title is misleading and sensationalist, implying that there was a significant market movement when in fact the major indexes were mostly flat or slightly changed.
- The article does not provide any clear explanations for why gold rose while bitcoin sank, instead relying on vague terms like "mixed earnings reports" and "producer inflation data".
- The article uses contradictory statements, such as saying that gold was expected to suffer but then rallied, without providing any evidence or reasoning for this change of expectations.

One possible way to approach this task is to break down the question into smaller sub-questions that can be answered in a step-by-step manner. For example:

1) What are the main factors driving the markets on Friday?
2) How did American Airlines Group (AAL) perform on Friday and what are the analysts' opinions on it?
3) What are some potential investment opportunities and risks based on the article and other sources of information?
4) How can I diversify my portfolio to reduce risk and increase return?
