$ARM Holdings Ltd(ARM)$  buy at 55 and keep buying on the dios to bring average cost down and wait for the rebound. Stocks like ARM are volatile in trading, hence opportunities to take in profits do arise. Personally, I have had a good run when the stock opened post ipo. My strategy using dollar coat averaging paid off the past two days. ARM Holdings is eyed by the megacap chip industry and companies in this business are buying up to gain a foothold on ARM stock - Nividia, Advanced Micro Devices, Samsung, Taiwan Semi-Conductor, Apple, Synopsys and Google. Softbank is the largest shareholder in ARM. So muxh attention from these huge companies mean only one thing for ARM. The stock will do well in the long haul. The past two days saw ARM stocks trading between its ipo opening price of $55 and a high of $70. Strong support is seen at $60. I expect ARM to go below its opening price once the ipo fervour dies down and I will pick up more and wait for the rebound, which will come about sooner than later. Hence investors who are worried that ARM will drop to $30 shoukd not wait for this as it may never arrive. Better to pick up some now, yes buy more if it ever comes down to $30 as your average cost will be lower and able to catch profits on the way up again. There is just so much interest in this stock now and ARM will stay strong aroumd $56 to $63. Pray you do not miss the boat!
