"I had some airline stock, but the airlines tanked. I didn't have a lot of money in them, though"

In this quote, Mickey Gilley is referring to his experience with purchasing airline company stocks. He had invested some of his cash in airline company stocks, but unfortunately, the airline market was not doing well and also the supplies he had actually purchased had actually lost value. Regardless of this, he was not as well worried as he had not invested a big amount of money in the stocks. This quote is a pointer that purchasing supplies can be high-risk which it is essential to be aware of the possible dangers before investing. It also highlights the relevance of branching out investments, as investing in a range of stocks can help to minimize the threat of shedding money.
