Leading digital streaming device manufacturer, Roku Inc (NASDAQ:ROKU), continues to tumble. The company reported earnings on November 7th, but they were poorly received by the street. Today, ROKU stock is falling by $1.69 to $44.04 a share. Traders should note that the shares are now trading below the important 200-day moving average which is a sign of weakness. The trend in the stock is now down and there should be more downside in the cards before a bottom will be found. The next key support level for ROKU stock will be around the $37.00 area. This level is where the stock broke out in mid-June 2018 and will likely be defended again when that level is retested.
