It was not because @CarlosVignote aka "Here I am" aka "Black" post on Yahoo forum.
It was because the intraday shorters and those who held shorts since Monday (multiday) needed to close prior to going into the weekend.
Gasparino and anyone with basic trading knowledge knows what happens on Fridays within 30 minutes of market close. 100s of equities have short squeezes on Fridays when the short positions cover with buys to exit going into the weekend. Many traders will also buy the dip and ride the short squeeze up and then sell in the last 2 minutes of trading.
This is why you will often see at 3:30pm to 3:45pm Eastern a rapid dip followed by a rapid recovery up to 3:55pm followed by a smaller selloff dip before market close at 4:00pm.
Gasparino knew there would be shorts covering and so he timed that tweet to make it appear as if he was the cause. Why? Because so many of these business reporters get compensated or additional airtime when they can post news that makes the market move.
If you trade, often Monday and Friday are where the money is made because you'll get all kinds of volatility and momentum.
Yo Carlos; not even, it was the Power of Song that caused the shares to rise. You can google it, but I put it here to make it easy for those here who do not know how or may be unable to google, enjoy, it'll set your toe a-tappin':
