These stocks are downright scary.

Whatever your desires are this Halloween, there's no denying that this has been one horrifying year for select tech stocks – especially those that were once thought to be impervious. Investors have found a degree of stability in Apple (NASDAQ: AAPL), but with other big players fluctuating – including Microsoft (NASDAQ: MSFT) and Google (NASDAQ: GOOG) – it's becoming increasingly difficult to pinpoint the next big thing in technology companies. Even newer trades – such as LinkedIn (NYSE: LNKD), which proved to be a stronger trade than its critics expected – are having a roller coaster year.
