Shares of Citigroup closed at $25.79 Wednesday, down 4% year-to-date, following a 44% decline during 2011. The shares trade for just under half their reported June 30 tangible book value of $51.81, and for less than six times the consensus 2013 EPS estimate of $4.54. The consensus 2012 EPS estimate is $4.09. Citigroup reported second-quarter earnings of $2.9 billion, or 95 cents a share, matching its first-quarter results, but declining from $3.3 billion, or $1.09 a share, a year earlier. For investors with a long-term horizon, analysts see a huge potential for capital returns from Citigroup, as capital tied up in the company's Citi Holdings subsidiary -- which holds assets that are running off, as part of CEO Vikram Pandit's "good bank/bad bank" strategy to right-size the balance sheet -- is slowly released. The company also has another $63 billion in deferred tax assets that could eventually be utilized, according to Atlantic equities analyst Richard Staite. O'Connor's price target for Citigroup's shares is $40, and the analyst estimates the company will earn $4.05 a share this year, followed by 2013 EPS of $4.64, excluding DVA/CVA. The analyst said that "2Q12 was a step in the right direction for C being able to deliver respectable earnings in a tough macro and capital markets environment." O'Connor added that "one issue for the stock, in our view, has been the volatile EPS power (good earnings in good macro quarters and very weak in bad macro quarters) and a few more quarters like 2Q should help the stock close its valuation discount to peers."
