Watching AH quotes last night, the low was 6.27 with most trades between 6.6-6.7. In pre-market it was similar, low of 6.04 and the range mostly between 6.00-6.60.
Trading this morning looks like skilled traders driving the price down, taking advantage of day traders trying to guess the bottom. When typical day traders are done, ACTV may rise in price. But until then skilled traders will take advantage of other day traders as they exit their positions to avoid a worse loss.
That is the only explanation for ACTV being driven so much lower than AH and pre-market sentiment indicated.
