Facebook: Like it but be cautious to invest

Facebook has again made investors pull long faces as they saw another record low for the company’s stock on Tuesday. Shares are losing 1.6% in the early session on Wednesday, after tumbling a whopping 6% to $21.71 a share the day before.

The shares are now 43% below the $38 a share IPO debut on May 18. The company has lost over 40 billion dollars in value since coming public.

Investors had hoped to see more progress in terms of user growth and in how the company is capitalizing on the rapid rise in mobile usage.Analysts predict the major investors are likely to rid themselves of at least some of their holdings.
