NEW YORK (TheStreet) -- Monetizing followers on Twitter (TWTR) - Get Report, friends on Facebook (FB) - Get Report and connections on LinkedIn (LNKD) has not been easy. The charts are negative for Twitter, reflecting its difficulties. The charts for Facebook are positive, suggesting that it's progressing favorably. The charts are neutral for LinkedIn, but show significant earnings volatility so far in 2015.

Twitter reports after the closing bell on Tuesday, and analysts expect the company to report earnings of 4 cents a share. Pointing up the difficulties involved in monetizing social media users, USA Today reports that nearly one billion Twitter users have opted out of the platform citing usage difficulties.

Even so, it reiterated its buy rating for Twitter with a price target of $50.

The weekly chart is positive, with the stock above its key weekly moving average of $218.30. The momentum reading is projected to rise to 45.93 this week, up from 36.04 on July 24.
