NEW YORK (CNNMoney) -- Earnings and buyouts were the main talkers on StockTwits Wednesday, with tweets focusing on FedEx, Yahoo and ZAGG.
Shares of FedEx (FDX, Fortune 500) jumped nearly 3% after the shipping company reported fourth-quarter earnings and sales that topped forecasts. FedEx also boosted its forecast for the coming year.
Yahoo (YHOO, Fortune 500) was also in the spotlight, amid reports that CEO Carol Bartz may be on the way out.
And separate reports named Yahoo as a possible bidder for Hulu, amid talk that the video streaming website was considering putting itself up for sale.
Tweets were also lighting up over ZAGG Inc. (ZAGG), a company that manufactures accessories for Apple's (AAPL, Fortune 500) iPhone and iPad among other mobile devices. ZAGG shares soared 9% Wednesday, a day after the company said it bought rival iFrogz for $105 million.
All of that is giving StockTwits users plenty to tweet about:
JonathanFlorida: $FDXbeats numbers and gives decent guidance - most expected disaster, at least bad guidance. Costs moderating, yep, oil now $90 from $110.
Alphalfuh: Fred Smith @ $FDXsays we are in middle of soft patch but thinks next 12 months will improve materially. Emerging markets are sound.
charlesrotblut: $FDXhad a decline in average U.S. daily volume; not surprising given the economic data we've been seeing.
cselland: if they call the company HuHoo I'm all for it - otherwise not so much $YHOO.
TMTanalyst: I find the conflicting $YHOOfor HULU articles hilarious. Also funny? Bartz still having a job.
ChiBullsTrader:$ZAGG target raised to $20 from $18 at Northland Securities - after iFrogz acquisition.
markflowchatter: $ZAGG index managers are gonna chase ZAGG up to $14 + is my thoughts, i have Northland report, reads well, tgt to $20, congrats all.
