I don't know if it's gambling or not. The lines sometimes blur. I mean, even blackjack players employ math and strategy.
I absolutely think you will make money in the airlines. The questions for me are how much and over what time horizon.
Now that you are invested the next question is when to sell. I find that deals are easy to find, but when to get off the ride is the hard part. Example being, I bought a $1,000 of Tesla the week of the IPO for $19/ share. I sold all of it at less than $100 because I thought it was way overvalued for a company that continually had production timing issues and still hadn't turned a profit. My blood pressure rises 10 points everytime I see the stock price.
