How should you choose the best investments with the market being so turbulent and volatile right now?

Jennifer Lane, a certified financial planner with Compass Planning, answers NECN Business viewers' questions.

Jason in Brockton asks: "My 401k automatically put me in a target date fund when I enrolled last year. My friend says that fund has the highest expenses of all our choices. How should I go about comparing my options?"

Betsy in Worcester writes: "How do I pick a mutual fund? It seems like it should be obvious but I really don't know where to start."

Amed in Hudson asks: "How long is too long to keep an investment like a mutual fund? I inherited some funds a few years ago from my grandmother. They've gone up, so I would owe taxes if I sold now."
