I would recommend:
A) watching Friday estimates and adjust your weekend holdings accordingly on Friday/Saturday as the actuals hit
B) adjust your Starbonds either on Friday/Saturday or on Sunday after the opening weekend adjusts go live. It's very easy to bleed out leaving money on the table when movies and Starbonds end up on the wrong side of reality, and with Starbonds it's an easy adjust.
C) just be aware of the marketplace. Right now everything is underperforming, so you're better off shorting most things and being very picky about when to go long. And as for shorting:
D) most IPO's continue to decrease after launch, particularly if they don't have a release date and they're not wide
E) it almost always pays off to short limited releases, particularly a week or two before release. They get very overvalued. Many trade in the $5-12 range and end up cashing out under $1 twelve weeks later. If you leave your money in there for the full run, it's unavailable for awhile, but considering the price tag it's not that much money. If you want to pull it out sooner, there's usually a sizeable decrease by the week or so after opening.
