selling them after they adjust on Sundays (excepting holiday weekends, etc). This will allow you to take your cash and move on.
With a smaller port - you have to think "short term." Take your profits and move onto the next opportunity...however....I think playing openers is one of the FASTEST ways to build your port, so if you can, AND want to roll the dice, I think openers offer you ONE of the fastest ways to build your port.
When I first started, I virtually (some exceptions) played the openers every week, and maxxed as much as I could afford on every stock...sometimes, just putting all my $ into the opener that I thought would adjust the most - NOT necessarily the opener that COST the most...you can make just as much $$ on a movie that costs $30/share and adjusts up or down 5 points, as you can with an opener that costs $55/share and adjusts up or down 5 points..the difference is (obviously) is you tie up less cash.
Think "short term" gains and move on...with a smaller port.
