<prompt> Human: Hello I have a margin account with about 10k invested in mutual funds and ETFs. I get 4x buying power at a 3 interest rate. Is it a bad idea if I bought 100 V and 100 MA with the margin and sell covered calls on those shares every month?Edit: Anyone mind elaborating on the cons. Are you suggesting I invest the margin more diversely or stay out all together?  <response>: Its going to work great until it doesnt.
