Gap (GPS) was very strong in the after-hours trading in reaction to its better-than-expected numbers Thursday, but it looks like that strength was fleeting.
In this updated daily chart of GPS, above, we can see prices are near the low of the day after earlier strength above the declining 200-day moving average line. Volume is relatively heavy but not north of 20 million shares, which has happened on some other strong days. Rallies can happen in an instant on very strong news, but more often these rallies have a better chance of survival when there has been some accumulation beforehand. Not visible on this chart -- sorry.
