RKLB: Stock May Attract Buying Interest at Key $55 Support LevelRocket Lab CorporationBATS:RKLBtimothysmith78Rocket Lab (RKLB) shares gained ground in premarket trading on Monday, following an eight-week sell-off that has seen the space infrastructure company lose nearly 60% of its value from it's record high set in late May. Despite inking several lucrative deals in recent weeks, including a $266 million Pentagon contract, the rocket maker's shares have tumbled along with SpaceX (SPCX) and the Procure Space ETF (UFO) as investors take some profits off the table in one of this year's best performing sectors. Taking a closer look at RKLB's chart, the shares have traded lower within an orderly descending channel since their May peak, a move that has coincided with the RSI moving toward oversold territory. While weak momentum could see the shares continue falling over the short-term, it's worth keeping a close eye on the key $55 level. This area on the chart may see bargain hunters look for buying opportunities around last year's September swing high, which also closely aligns with a brief retracement to the 50 MA during the stock's strong trend higher in December.
