Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of J.C. Penney (JCPN.Q) were regaining some life today, jumping as much as 11% after an analyst suggested the struggling retailer could add value by converting some of its stores into a real estate investment trust.

So what: Omar Saad, a retail analyst with the ISI Group, said that if the department-store chain converted 300 of its top locations into a REIT-like entity, it could make $1.2 billion in net income as a landlord alone. Saad gave that portion of the business a $40 per-share value and assessed the remaining 800 J.C. Penney stores at a value of $6 a share, if they remained traditional retail outlets. Today's share-price jump also come amid positive reports about the launch of Canadian label Joe Fresh at 700 of Penney's 1,100 stores.

Now what: Today's developments seem to be only further confirmation that investors have given up on Penney as a retailer. The company posted nearly $1 billion in losses last year and will need to make serious improvements to avoid a similar disaster in 2013. Perhaps the real-estate avenue could generate more cash, but Saad seems to be mistaken if he thinks removing the 300 best stores will leave a retail chain that has any value at all. J.C. Penney didn't comment on Saad's proposal. I'd be skeptical until the company seems to believe in the real estate angle.
