We're again trimming a stock up 46% last week and 80% since our April initiation

Shortly after the opening bell, we will be selling 55 shares of Arm Holdings at roughly $314 each. Following Tuesday's trade, Jim Cramer's Charitable Trust will own 130 shares of ARM, decreasing its weighting to roughly 1% from 1.44%. We will be locking in more big gains in Arm following another huge rally. Shares of this chip designer rallied 46% last week, with roughly half the move coming after Nvidia said on its earnings call that its Arm-based Vera CPU has visibility into $20 billion in revenue this year. That's great forn Arm's royalty business. We wrote in Friday's HomeStretch about how we planned to handle this second parabolic move since we initiated an Arm position on April 20, roughly five weeks ago. Arm's recent outperformance has pushed its position weight in the Trust from 1% after last Monday's trim to around 1.45% as of Friday's close. By making another trim back to 1%, we can better manage the risk of this exponential move by bringing the position closer to our original weighting. It also allows us to raise cash to fund other purchases or to potentially buy back shares of Arm if the stock were to pull back.

That may mean our sales won't come at the absolute highest prices, but letting them run would violate our discipline. From this trade, we will realize a big gain of around 80% on shares purchased in our April initiation. (Jim Cramer's Charitable Trust is long ARM, NVDA. See here for a full list of the stocks.)
