The contrast between the $1,059,666,527 position in United Therapeutics Corp (UTHR) and the $440,696,066 initiation in Nvidia Corp (NVDA) tells a story of a firm tempering its heavy bets while simultaneously making room for high-velocity sector plays. Renaissance Technologies, managing a total value of $63,929,893,013 across 20 holdings, rarely makes a move that isn't calculated to the decimal point of a percentage, and this latest filing for the period ending March 31, 2026, is no exception.

The billion-dollar anchor shifts United Therapeutics Corp (UTHR) remains the firm's largest holding, yet it carries the "Decreased" flag, signaling a slight reduction from its previous weight. At $1,059,666,527, it commands a portfolio weight of 1.657544658778827%. Seeing this ticker as the crown jewel of the portfolio highlights a continued preference for specialized biotechnology, even as the quant-heavy [whale](https://13fwhale.assettrendreports.com/en/whale/renaissance) trims its exposure to lock in gains.

Not far behind in the ranking is Palantir Technologies Inc-A (PLTR), which also bears the "Decreased" tag. With a total value of $1,021,901,255, this position constitutes 1.5984717114921478% of the fund’s total assets. It is a massive block of shares to move, and the reduction suggests the systematic model is tightening its grip on one of the most volatile names in the portfolio.

Where the new blood flows The most intriguing addition to the portfolio this quarter is Apple Inc (AAPL). By entering with a value of $780,569,445, the fund has immediately made this a core holding at 1.2209772427450691% of total assets. It is a significant "New Position" that arrives with a clear, aggressive intent, especially when compared to the existing, more niche, positions like Kinross Gold Corp (KGC). KGC, which holds a value of $779,676,525 and accounts for 1.2195805252504561% of the fund, was actually increased during this period, showing that the firm is balancing new tech bets with a sustained conviction in gold mining stocks.

Trimming the edges of the tech allocation Micron Technology Inc (MU) sits at a value of $730,739,401 with a portfolio weight of 1.143032416543237%, and like its peer Palantir, it has been subjected to a "Decreased" flag. This systematic paring down of semiconductor exposure is offset somewhat by the fresh entry into Nvidia (NVDA), which now occupies $440,696,066 of the [screener](https://13fwhale.assettrendreports.com/en/screener) assets.

Verisign Inc (VRSN) was also granted an "Increased" status, rising to a value of $699,915,982, or 1.0948180092490905% of the portfolio. This steady accumulation contrasts sharply with the "Decreased" flag on Exelixis Inc (EXEL), now valued at $588,750,730, representing 0.9209318243036616% of the book. Similarly, Franco-Nevada Corp (FNV) has been trimmed to $548,183,692, holding 0.8574763168906416% of the portfolio.

The full roster of recent activity The firm continues to churn its holdings with precision, introducing several other fresh, multi-million dollar positions:

* Sandisk Corp (SNDK): $507,997,533 * Chevron Corp (CVX): $416,984,243 * Argan Inc (AGX): $332,726,140

With only 20 holdings in total, the concentration level remains relatively high for a portfolio of this size. The decision to initiate these new positions while pulling back on long-standing anchors like United Therapeutics and Palantir implies a rotation toward names that likely offer better risk-adjusted returns within the proprietary Renaissance model. Every dollar added to Chevron or Argan is a dollar moved away from the deeper, older positions, and these transitions are rarely arbitrary. The firm clearly favors a lean, high-conviction approach, as evidenced by the limited number of holdings across the entire $63 billion book. Each "New Position" is an explicit statement on current market dynamics, filtered through the firm's long-standing quantitative approach to asset selection.
