"Twitter: No Relief in Sight," by Barron's senior editor Jack Hough: "Shares soared past $70 after the IPO. Last week they fell below $17 and may be on the way to a hat size."

Be smart: "[A] markdown isn't the same as a bargain. Twitter is nearly as expensive as Facebook, whose revenue and profit are galloping higher, based on next year's projected earnings before interest, taxes, depreciation and amortization. That means Twitter must bounce back quickly, or get bought, or suffer a continuing stock-price decline, perhaps to single digits. The first two outcomes are looking increasingly unlikely."
