Jim Cramer, a prominent financial commentator, announced his intention to purchase shares of Palantir Technologies ($PLTR) and Tesla ($TSLA), describing them as providing 'protective intellectual blankets.' Cramer mentioned he is working on a 'Sunday brainstorm' regarding these investments. In related news, Stifel has raised its price target for Tesla to $492 from $411, maintaining a Buy rating. This adjustment reflects analysts' confidence in Tesla's potential for robust multi-year growth, particularly with the upcoming refresh of the Model 3 and Model Y. Following the announcement, Tesla shares rose by approximately 3% in premarket trading. Additionally, significant insider trading activity was reported for Palantir, with insiders disposing of shares worth over $37 million, which may indicate future developments for the company.
