Overstock’s first big jump came in February, when shares soared 23% after an encouraging fourth-quarter 2015 report but not so much because of its actual headline numbers. For perspective, Q4 2015 revenue climbed just 2% year over year, to $480 million, while net income was $110,000, or breakeven on a per-share basis and down from $0.06 per share in the same year-ago period.
