Last up is Lowe's ( LOW), another big-name stock that's looking "toppy" right now. Lowe's has been riding a rising tide of sentiment for anything related to building -- and as the nation's number-two home improvement retailer, the 20% rally that shares have seen in the last year has been deserved. But a double top pattern in shares makes it look like the uptrend could be coming to an end -- at least temporarily. The double top is a setup that's formed by two swing highs that hit their heads at approximately the same price level. The sell signal comes on a breakdown below the near-term support level for shares, currently right at $36. If shares slip below that price, we've got a sell signal for shares. I still think that building stocks look attractive right now -- and in fact, top rival Home Depot ( HD) isn't looking toxic in April. But it's important to remember that you can't fight the tape, and Lowe's is showing traders some bearish price action right now.
