Stocks moved sharply lower last week amid concerns that the strengthening economy could lead to higher inflation and a more hawkish Federal Reserve. Many analysts believe that the labor market has reached or surpassed full employment, and wages are starting to accelerate. The unemployment rate reached a 50-year low of 3.7%, but the 0.3% increase in average hourly earnings was the most highly watched part of the report.

Next week, traders will be watching several key economic indicators, including the consumer price index on Oct. 11 and the consumer sentiment report on Oct. 12. With the S&P 500 forming a possible double top, small-cap stocks in free fall and tech stocks under pressure, traders will also be keeping a close eye on technical factors influencing the market over the coming week following a sharp sell-off last week.

The SPDR S&P 500 ETF Trust (SPY) fell 1.49% last week. After nearly reaching R1 resistance at $294.15, the index formed a bearish double top chart pattern.
