What is the penalty or fee for selling Gabelli Healthcare and Wellness RX Trust mutual funds and purchasing an ETF of its equivalence in Fidelity or Vangard?

Hi Everyone,

I have a question about 'cashing out' and buying into another product. So.... My mom has shares in Gabelli Healthcare and Wellness RX Trust and wow... it hasn't been performing well so we are both thinking about selling off all the Gabelli Healthcare and Wellness RX Trust mutual funds and purchasing Fidelity's FHLC ETF or Vanguard VHT (both are equivalent to Gabelli Healthcare and Wellness RX Trust because they've been performing better. Will she have to pay any fees? If so, how much? thanks everyone!

:)
