Similar to wise buying decisions, exiting certain underperformers at the right time helps maximize portfolio returns. Selling off losers can be difficult, but if both the share price and estimates are falling, it could be time to get rid of the security before more losses hit your portfolio.One such stock that you may want to consider dropping is Zumiez Inc. ZUMZ, which has witnessed a significant price decline in the past four weeks, and it has seen negative earnings estimate revisions for the current quarter and the current year. A Zacks Rank #4 (Sell) further confirms weakness in ZUMZ.A key reason for this move has been the negative trend in earnings estimate revisions. For the full year, we have seen four estimates moving down in the past 30 days, compared with no upward revisions. This trend has caused the consensus estimate to trend lower, going from $1.02 a share a month ago to its current level of 89 cents.Also, for the current quarter, Zumiez has seen four downward estimate revisions versus no revisions in the opposite direction, dragging the consensus estimate down to a loss of 8 cents a share from earnings of 2 cents over the past 30 days. The stock also has seen some pretty dismal trading lately, as the share price has dropped 15.9% in the past month.Zumiez Inc. Price and Consensus Zumiez Inc. Price and Consensus | Zumiez Inc.
