Aecom (ACM) shares are coiled in a bull flag the past month after a strong run in Q4 from 70 up to 85 and now seeing a setup for higher prices with a breakout above 85.50 likely sending the stock to new highs into 90 and beyond. The small cap industrial is in a sector seeing positive money flows and a stock that quietly is at all time highs with blue sky territory above. A close back under the 82 level would be a prudent stop.
