Twitter (TWTR) stock has taken an incredible hit lately. With the help of the recent lockup expiration, shares have sunk 50% from the all-time highs it achieved in late 2013. In fact, Twitter shares recently reached all-time lows.

In the following video, senior Fool technology specialist Daniel Sparks examines the reasons for Twitter's decline. He identifies two red flags that have investors concerned: a pricey valuation and slower-than-expected user growth. But Daniel also notes that the market's dramatic response to these red flags may be overblown. A bit of perspective reveals an excellent and rapidly growing business that could make a solid long-term holding after the sell-off.
