Terra Industries (TRA) has received interest from CF Industries of a letter of intent to merge, where CF would give 0.465 shares per Terra stock. CF is currently trading at $83.14, which means TRA would be valued at $38.66 if the deal goes through. The deadline is August 21. TRA had declined CF's advances in the past, but there are many in the market (chemical manufacturing) that want the deal to pass. TRA is currently at $30.39, up $1.54 today.I had both TRA and CF on my short watch list created a few months back, but never bought either of them.My guess is the stock runs up to a few points shy of the takeover target prior to 8/21. I'm in for 1,000 shares at $30.
