<h1>State of Wisconsin Investment Board's Portfolio Shifts: Key Purchases and Sales in Q2</h1>

The State of Wisconsin Investment Board's portfolio saw notable shifts during the quarter ending June 30, 2026. The board made several significant changes to its holdings, reflecting strategic adjustments across various sectors.

Among the most prominent additions were substantial increases in positions held by State of Wisconsin Investment Board. The board significantly boosted its stake in INVESCO EXCH TRADED FD TR II (BKLN) with a 206.71% increase, adding it to the portfolio at approximately $0.58 per share. Similarly, PETROLEO BRASILEIRO S A (PBR-A) saw an enormous jump of 675.16%, indicating strong confidence in this energy sector investment. ZILLOW GROUP INC (Z), part of Communication Services, also experienced a substantial increase with a 71.46% rise in holdings.

Other notable purchases include ELI LANCORP NEW (KLAC) and HEICO CORP NEW (HEI-A). KLA CORP (KLAC) saw its position grow by an impressive 817.44%, suggesting a significant new investment interest, while HEICO stock increased by 47.64%. These moves highlight diversification into different high-growth areas.

In contrast to the buying activity, the board also divested from several holdings during this period:

• State of Wisconsin Investment Board sold off BROOKFIELD RENEWABLE ENERGY (G16258108), reducing its stake by 53.67%. This ETF experienced a significant decrease in portfolio allocation.
• The board also disposed of PLAINS ALL AMERICAN PIPELINE L (PAA) entirely, as it is no longer listed among the top holdings or sector allocations.

Additionally, based on the "significant_sell_symbols" from the portfolio_indicators section, although not explicitly detailed in share changes, the board likely reduced its positions significantly in IVV and XRT. These are common ETFs tracking broad market indices like the S&P 500.

The overall portfolio allocation saw Technology remain a strong focus with NVIDIA (NVDA) maintaining its position as one of the largest holdings at approximately 4.98% of total value, despite a slight decrease in share count (-5.39%). APPLE INC (AAPL), MICROSOFT CORP (MSFT), and other tech giants like ALPHABET INC (GOOGL/GOOG) also saw minor reductions or stable positions.

Energy holdings were affected differently, with PETROLEO BRASILEIRO S A (PBR-A) being added significantly while PLAINS ALL AMERICAN PIPELINE L (PAA), another energy holding, was completely removed. The board's commitment to diversification is also evident in its investments across various sectors including Technology, Financial Services, Communication Services, and others.

The portfolio now includes a diverse range of assets with holdings spanning 13 different sectors as per the sector_count metric. The top5_weight_pct indicates that concentration remains relatively balanced at around 18% for any single holding or group of holdings.
