Since bottoming out back in March, Home Depot (HD) has been under accumulation, steadily advancing in an uptrend of rallies followed by consolidation at higher levels. A spring rally was followed by a summer of consolidation that culminated in a bullish Ascending Triangle breakout last month. Since then, a bullish Flag pattern has emerged. The shares staged a sharp rally in October, followed by 3 weeks of sideways consolidation, and this week the shares have broken out into a second upleg. This breakout to new all-time highs has occurred on a jump in volume indicating increased investor interest.
