Two things I've heard often from coworkers on the topic of stocks:

1. This company's share price has gone down 90%. So, it must be a good time to buy, right? Example: Tilray went from $300 to $30. The pain wasn't over. It dropped to $3.
2. The share price of Company A is higher versus that of Company B. So, B is a better buy, right? Example: Apple is expensive ($145) but BlackBerry is cheap ($5).

I learned about the stock market in high school in the previous century. Most of these people are older than me and they still don't have a clue.
