U.S. HOT STOCK FUTURES: HOT STOCKS TO WATCH

Among the companies with shares expected to actively trade in Monday's session is Box Ships Inc. (TEU).

Box Ships said it is withdrawing its public offering of 700,000 units, which was part of an effort to finance the acquisition of two containerships. Shares were off 4.5% to $8.03 after hours.

Watchlist:

AT&T Inc. (T) said about 7,000 core wireline employees have failed to ratify a one-year contract extension and said it will continue to work with their union to reach an agreement.

Spectrum Pharmaceuticals Inc. (SPPI) has again extended its tender offer for fellow biopharmaceutical company Allos Therapeutics Inc. (ALTH), so that the companies can continue cooperating with the Federal Trade Commission. It also said the European Commission has recommended against the approval of Allos's peripheral T-cell lymphoma treatment Folotyn.

Stryker Corp. (SYK) has voluntarily recalled two metal devices used in hip implant surgeries, citing risks associated with fretting and corrosion.

Yahoo Inc. (YHOO) and Facebook Inc. (FB) have reached a settlement ending patent litigation between the firms, drawing an end to a nasty but ultimately short-lived dispute that had roiled Silicon Valley. The agreement is intended to further expand partnership ties between the firms that predate the litigation, and doesn't involve any payments.
