Twitter Inc.'s stock edged up less than 0.1% in afternoon trade, erasing earlier sharp losses, to put it on track to extend its win streak to 10 sessions. The stock, which was down as much as 1.5% at its intraday low after the social media company announced a $1 billion convertible debt offering, seesawed in and out of positive territory in the final hour of trading.

On Tuesday, the stock had run up 5.1% after S&P Dow Jones Indices said it would add the stock to the S&P 500 Twitter shares have more than doubled (127%) over the past 12 months, while the S&P 500 has gained 14%.
