The major U.S. indexes moved sharply lower last week amid ongoing political risks, including President Trump's newly announced tariffs and decision to rebuild his cabinet, as well as Special Counsel Robert Mueller's subpoena of the Trump Organization. The 30-year Treasury bond rose nearly 1%, sending yields sharply lower, as investors sought out safe-haven assets to ride out the market turbulence.

International markets were mixed over the past week. Japan's Nikkei 225 rose 0.99%, Germany's DAX 30 rose 0.35%; and Britain's FTSE 100 fell 0.87%. In Europe, the regional economy appears to be very strong, but inflation remains sluggish, and the European Central Bank's (ECB) bond buying programs may persist past September after all. In Asia, China's economy posted stronger-than-expected gains due to export demand but continues to face debt-related risks.

The SPDR S&P 500 ETF (ARCA: SPY) fell 1.67% over the past week. After briefly surpassing its prior reaction highs, the index moved lower to test the 50-day moving average at around $273.47. Traders should watch for a breakdown to lower trendline support at around $270.00 or a rebound higher to test upper trendline resistance at $280.00. Looking at technical indicators, the relative strength index (RSI) appears neutral with a reading of 53.13, but the moving average convergence divergence (MACD) has been slowly trending higher, suggesting a bullish bias over the coming week.

The Bottom Line

The major indexes moved lower over the past week, but moderate RSI readings and moderate to bullish MACD readings point to a potentially bullish week ahead. This week, traders will be closely watching several key economic reports, including the FOMC meeting results on March 21, jobless claims on March 22 and new home sales data on March 23. The market will also be keeping an eye on the evolving geopolitical risks moving into the new week. (For additional reading, check out: 8 Stocks for Big Short-Term Gains.)
