Technology giants stumble, will the "year-end rally" in the US stock market be in jeopardy?

On Monday, US stocks weakened once again, casting doubt on whether US stocks can remain strong during the strongest period of the year. The problem mainly lies with the surging technology stocks, which have been the main driver of the S&P 500 index's 34% increase since its low in April. However, these once rising stars are now stagnating, leaving the market to rely on other sectors that are more easily affected by signs of economic slowdown and weakening consumer confidence.
