Shares of Twitter are getting hammered Tuesday after earnings reports disappointed. Shares are down over 10 percent in mid-day trading and hovering at the $43.00 range.

Monday evening Twitter (TWTR) reported profit and revenue numbers as expected, but their revenue forecast was behind estimates. 

Twitter is having difficulty adding new members and four analysts downgraded the stock.

Tuesday, RBC Capital Markets downgraded Twitter's price target from $65 a share all the way down to $47. The company also changed their view of Twitter from sector outperform to sector perform.

Stifel Nicolaus advised a "sell" rating on Twitter when it had been recommending investors to "hold."

Bank of America changed their rating from buy to neutral and gave it a $50 price target.

Twitter shares were as high as $65 a share in February but have leveled down in recent months.

Part of the reason Twitter could be having trouble is because of the company's long failure to cash in on the true value of a Twitter member. Twitter is free to join for anyone and rarely do people actually spend money on the actual service. 

Many companies spend the cash to get their "promoted Tweets" out on Twitter but often those go ignored or get "marked as spam" by Twitter users.

Twitter shares opened at $42.25 Tuesday. That's the company's lowest level since Aug. 1.

The company first went public with an initial public offering (IPO) back in November 2013. Shares were in the $40 range back then and hit $69 a share in December 2013.

Since then, however, shares have been mostly on a decline. This summer the stock enjoyed a slow rise up to the $53 range but fall hasn't been especially kind to Twitter with a steady dip in share prices.
