NEW YORK (TheStreet) -- After hitting new market highs last week, the market has been trading off this week. Several key elements have given market investors the excuse to de-risk their portfolios this week:
1) Quarter-end rebalancing: Investors are rebalancing their portfolios, away from equities and into bonds and other asset classes.
2) Geopolitical risks: The situation in the Middle East continues to be unstable with ISIS increasing its stronghold in Iraq and now Israel and Hamas are threating to go to war.
3) European Economy: Troubles at one of Portugal's top banks reignited concerns about the health of the overall European economy and languishing economic recovery in the Eurozone.4) Earnings Season: Corporate earnings season is about to kick into high gear further fueling market uncertainty, but also substantiating or derailing market valuations. 5) FOMC Minutes: The Fed is becoming increasingly concerned about how Fed-driven liquidity might be creating "excessive risk taking" in the economy. They also acknowledge that economic data continues to be mixed. Overall the Fed minutes were in line with expectations, but readers see what they want to see to justify their market positions.

Most market pundits remain bullish on the market for the second half of this year, given continued improvement in the U.S. economy and employment picture. But there are definitely some pockets of weakness in the economy such as retail. Reporting disappointing results earlier in the week, The Container Store's (TCS) CEO shared that it was experiencing a "retail funk". Apparently sluggish retail sales are not just about "the weather" after all. While consumers are buying homes and automobiles and other high ticket items, specialty retailers like The Container Store did not experience the much-hoped uptick in sales in the spring. Other retailers such as Family Dollar Stores (FDO), Wal-Mart (WMT), Lumber Liquidators (LL) and Tractor Supply (TSCO) have also experienced weaker-than-expected sales in the second quarter. Is the consumer being more selective with their spending behavior? Online and mobile shopping is facilitating an increasingly promotional environment for brick and mortar retailers. Discount shoppers are requiring bigger and bigger discounts to bring them into the stores. Interestingly, luxury brands appear to be doing better in this environment suggesting that "aspirational" consumers are willing to pay up for certain brands and shopping experiences. The iconic British luxury brand Burberry, for example, reported better-than-expected results, tempered only by the strong British pound.
