BlackRock, sell signal against a still-strong sector

BlackRock has just received a weekly sell signal — its first stage — ranking 90th among the 114 sell signals for US stocks. This week's drop was contained, a week of indecision rather than a breakdown, but the weekly structure remains bearish. Our quality band flags trading as not recommended: the stock still trades 13% above its 200-week average, within a financial sector that has gained 4% over the past month.
