I have in the past used the Sharelord basic covered calls strategy and followed their stock pick type recommendations. I ended up NOT making a profit after several months. This was in mid-late 2008 and you know what happened then!
If you look at the other thread in the above post you'll find a very informed comment relating to the potential upside/downside of this type of strategy.
I'm not dismising it, in fact I'm currently revisiting the basic covered call (with put) strategy as part of a plan to generate monthly income from my portfolio. This time I'll be a lot more cautious, put less cash in and always protect my positions.
I can't comment specifically about the collared call weekly strategy, but don't sell your house just yet!
Cheers,
Dwight
