Glory days are over for tech stocks

markets now title slate

New York (CNN Business)Earlier this year, tech stocks were on fire. Now many are struggling, and their prospects don't seem to be getting any better.

Tech has been rattled by the escalating trade war between the United States and China. Relations between the two countries could turn even more sour after Chinese tech giant Huawei's chief financial officer was detained in Canada.
Meng Wanzhou's arrest at the request of the United States sent shock waves through global stock markets last week. Chinese tech stocks were among the hardest hit.
Meanwhile, a Chinese court banned the sale and import of most iPhone models. The practical effect of the injunction is not yet clear. The ruling was announced publicly Monday but put into effect last week. Apple (AAPL) said in a statement that all iPhone models remain available in China.
    In the United States, fears about rising interest rates and slowing growth have sparked an exodus from former tech darlings like Amazon (AMZN) and Alphabet (GOOGL).
    For companies like Facebook and Netflix, the economic fears only pile onto existing problems.
    Facebook (FB) has lost nearly 20% of its value this year as it tries to fend off crisis after crisis. Netflix (NFLX) is up about 40% for the year, but has been stumbling since the summer when it missed analysts expectations.
