After a powerful rally, ARM's share price has run out of steam, says Mike van Dulken at www.accendomarkets.com.
Significantly, the advance has halted at a lower level than its latest two highs of the last nine months. And it is no longer outperforming the FTSE 100. Go short from 574.5p, targeting a drop to 520p, initially placing a stop-loss at 595p.
