Dear Mr. Berko: On your advice, I didn't buy stock in GoPro in 2015, when it was trading at $56. And about a year later, it fell to $8. But as it recovered and rose to $16, my stockbroker had me buy 1,000 shares. It immediately fell to $10. I sold it and took a 6-point loss. Now it's about $5, and he's advising me to buy another 1,000 shares. We both think it has finally hit the bottom. What do you think?
Also, what do you think of Southern Co., an electric utility that you recommended when it was…
