Palantir Technologies Inc. posted its best week since it went public in September, adding about $17 billion in market value as a broad rally in tech stocks helped fuel gains in the software maker.

Its shares rose 52% since Monday and touched a fresh intraday record at $33.50. The stock lost some of the gains on Friday after Citron Research said in a tweet it was shorting the stock with a $20 target. The company ended the session at $27.66.
