The overall stock market may have recovered from the Great Recession, but the tech sector has never fully recovered from the dot-com bust in the early 2000s. Here are seven rules for investing in high-tech companies while avoiding wild speculation:
Boeing says its net income increased to $1.65 billion in the second quarter, up by 52 percent from $1.09 billion in the same quarter a year ago. Boeing says revenue also increased 1.1 percent to $22.05 billion, slightly less than what analysts had expected.
The US unemployment rate fell to a five-year low of 7 percent in November. The robust job gain suggested that the economy may have begun to accelerate and fueled speculation that the Federal Reserve will scale back its economic stimulus when it meets later this month.
Stocks were mixed Wednesday as investors pushed the Dow Jones industrial average to another record but the Nasdaq composite edged lower. Tesla Motors' stock sank $25.65, or 14.5 percent, to $151.16 after it reported a loss.
Stocks fell Tuesday on mixed economic reports and concern about a government shutdown. Stocks edged lower in early trading, before reversing the losses to move modestly higher by late morning. The gains then fizzled out.
Stock market took a hit from Washington's budget battle Friday. A showdown over federal spending sent the stock market plunging in an afternoon sell-off that wiped out all the gains from a rally earlier this week.
