Uh oh.

Shares of Home Depot (HD) - Get Report dropped 2.68% in Friday's session breaking below their rising 50-day moving average for the first time in seven months, and potentially forming a long-term top on the daily chart. The drop in stock price was powered by a surge in negative volume, 145% greater than the 50% moving average of volume. This combination of price action, volume and technical deterioration suggest a top may, in fact, be in place, and the stock price could be headed considerably lower.

A steady pattern of rally followed by lateral consolidation delineated the 35% move higher off the November 2016 low. The most recent period of sideways price action began in May this year above the $153.00 level and continued into June, briefly breaking that support but then bouncing off the 50-day moving average. That bounce brought the stock back up to the May high area, but last week the move failed, and the stock dropped back through the June low.
