You'll know by looking at the pps if the report is good or bad for equity.
1. Only if the market is leaked the correct information. (likely) 2. Only if the price reacts based on true supply and demand principles only(not likely)
My biggest payday ever came from a stock (pending news) that had a steady 8 day drop in daily pps followed by a panic selloff the final day which dropped the pps 50%. Stock was halted, then reopened with a 1500% gain. This is easily accomplished by a MM driving the price down to panic investors, harvest stop losses, and steal large quantities of shares on the cheap. MM's think backwards. If they want your share, they will create a selling enviornment. All the investors with active stop losses were crushed! Once stop losses were harvested, the trading was halted so people could not get back in. Stock opened the next day with massive gains and volume.
I'm not saying that this will be the case with WAMUQ, however, we all watch the daily manipulation of this stock, therefore, anything is possible.
To all, sometimes things aren't as black and white as others describe and be very cautious with stop loss orders.
