Technology stocks abruptly lost steam Thursday afternoon after a steady rally. But in spite of yesterday's large losses, these stocks on the whole are still up nicely since the Fed cut rates in mid-September. Inevitably, some investors take profits after a long bullish stretch. On the whole, I am confident that tech stocks will continue to increase in value over the long run, but now might be a very choppy time for many of these stocks. With that in mind, I would like to shift our focus away from technology and health care, and focus on the financial world. Citigroup ( C) took a beating in the subprime market, but the company remains a strong investment play. While the company cut this quarter's earnings estimate by 60%, the future outlook holds more weight than past performance. With the bank cutting profit estimates so heavily at this point, there is far more room to beat guidance in the months ahead than to disappoint investors. Negative sentiment has already been built into the stock, creating this purchase opportunity. Citigroup's shares are trading well below their levels prior to late July's selloff. Furthermore, Citigroup possesses the means to not only stay afloat through the subprime crisis, but also to add strength. Let me explain how the company can add strength. The stock has a forward P/E of 9.90, a return on equity of 17.82%, and its revenue totals $88.41 billion. The last item I will mention is cash, and whether you like it or not, remember -- it's all about the cash! The man with the gold makes the rules! Citigroup has total cash of $987.98 billion, according to Yahoo! Finance. With the stock down nearly $1 already this morning to around $47.50 after a downgrade to "sell" by Deutsche Bank this morning, I will place a limit order to buy 10 March 42.50s (CCV) calls for $5.90 or better. Before I get to the email, let me tell you I have added five wins -- Penn Virginia Resource ( PVR), Pfizer ( PFE), Rowan ( RDC), Unit ( UNT) and Anheuser-Busch ( BUD) -- in just two days.
