Why Palantir Stock Is Rising Today?

Shares of $Palantir (PLTR.US)$ were up by roughly 3.4% as of 1 p.m. ET Monday, after having been up by as much as 4.6% earlier in the session. The big-data specialist's share price gains were apparently driven by CEO Alex Karp's 2022 letter to shareholders, which was published before the market opened. While the letter contained little in the way of detailed company-specific news, Karp laid out some commentary on Palantir's business and the software industry broadly.
