strow many stocks are down on minimal volumes, its year end. Some PI's sell at year end, so MM's mark the price down as they do not want them on their books at year end, and if they have to have them on their books, they want them at dirt cheap prices, to make good January profits when the markets wake up for the new year.
Markets always struggle December as money is taken out, then bloom in January as the money comes piling back in. Best time to buy, this week or next, and get in before the January rush of funds back into the markets.
