The data deals keep coming.

I.B.M. announced on Thursday that it was buying Algorithmics, a risk analytics company, for $387 million, expanding its services for financial institutions.

It is the latest acquisition in the data analysis sector. Last month, Hewlett-Packard agreed to pay $11.7 billion for Autonomy, a British company that searches and keeps track of corporate and government information.

I.B.M. has been particularly active in the area, making $14 billion worth of acquisitions in the last five years.

In 2009, the company paid $1.2 billion for SPSS, which makes statistical software. The same year it also bought Ounce, whose software allows companies to assess risks in their programming code. On Wednesday, I.B.M. announced a deal to purchase the data analysis company i2.

With Algorithmics, I.B.M. is pushing further into financial services. The company’s client list includes 25 of the top 30 banks, among them HSBC, Nomura and Société Générale.

“Today’s economic environment demands that financial institutions have more cash on hand, a better understanding of their financial standing and the ability to deliver more transparency to stakeholders,” Rob Ashe, I.B.M.’s general manager of business analytics, said in a statement. “Combining Algorithmics’ expertise with I.B.M.’s deep analytics portfolio will allow clients to take a more holistic approach to managing risk and responding to economic change across their enterprises.”
