The exact same thing happened with LNKD
on their lockup expiration.
They too announced a secondary offering around the time of lockup expiration in November 2011.
Next, the stock went UP to 92 from 88.
This was clearly manipulation to confuse the shorts and sucker longs into the stocks.
In the next 4 weeks, it plunged all the way to 60.
There is a flood of ANGI shares coming May 15.
43% of ANGI's shares will be free to sell, and who does not want to cash in since there is no end in sight to huge losses?
Their business model cannot work (Yelp offers the same for free and has millions more members).
You invest your money with them, and they do not pay you a return (dividend), instead, they need constantly more money from you to cover ever-increasing losses.
