After a recent successful test of support of the 50 day moving average, shares added +3.5% to our gains this week Friday’s action was interesting as Bloomberg reported that two other leaders in the industry (Holcim and Lafarge) are exploring a possible merger. That news sent EXP blasting to new all-time highs mid-morning, however they closed with only modest gains of +1.2%. Volume patterns look good as five of the last seven sessions have gains on above average volume. This was as the stocks was moving up from the 50 day moving average. Ranks remain solid and continued volume-backed gains would be encouraging. A close below the 50 DMA currently at $84.46 would be a serious concern. SEE MORE HERE
