Citibank is expected by analysts to continue its roller coaster ride on Monday as investors debate whether or not the bank has reached a sustained turnaround.

The troubled bank’s stock price rose by 18% during the first four days of last week after a number of positive statements were made about the value of the company’s stock.

Citibank’s stock price was further lifted on Wednesday and Thursday on the heels an optimistic presentation that Citibank CEO Vikram Pandit made at a company sponsored financial services conference in New York.

In his presentation, Pandit said that the company expects to see a 1.25% to a 1.5% annual gain on the company’s assets. Pandit also said that the company would earn $20 billion worth of earnings in its core businesses by 2012.

Earlier in the week, Citibank rose on the news that it had found a buyer for its troubled real estate unit to Apollo Global Management.

During the middle of the week, Citibank sold $2 billion worth of trust preferred securities which were well received by the market.

On Friday, the bank lost some of the momentum from the positive news of the week and fell 5%.

There is strong disagreement among investors about Citibank’s turn around. Some believe that the bank has regained its footing and will see a sustained return to profitability, but others believe that the company’s profits will be mitigated by heavy losses from its Citi Holdings division.

Citibank was the most actively traded holding on the New York Stock Exchange on Friday and will likely maintain that position on Monday as investors decide whether or not Citibank has turned itself around.
