We are deep into the high(er) interest period. I assume a lot of original participants of this thread adjusted their views on marginal loans. I'd be really curious to hear from someone who is still actively playing with this strategy.
I've been using margin since 2007. Sold off a good chunk of CVX to pay it down last fall. This is the lowest my margin has been based on percentage. At current IBKR rates, I'm letting the dividends pay it down.
