The past week within the UMBRELLA Strategy<\/strong> was characterized by a further rotation toward technology, artificial intelligence, and semiconductors.<\/p>

Positions in Micron Technology<\/strong><\/a> and Intel<\/strong><\/a> were significantly expanded, while Palantir Technologies<\/strong><\/a> and SpaceX<\/strong><\/a> also gained weight. Simultaneously, positions in Eli Lilly<\/strong><\/a>, Johnson & Johnson<\/strong><\/a>, and Bayer<\/strong><\/a> were reduced.<\/p>

MercadoLibre<\/strong><\/a>, whose weight had already been gradually reduced due to ongoing technical weakness, exited the UMBRELLA Strategy completely.<\/p>

Following these adjustments, the strategy comprises nine positions and remains almost fully invested with an equity allocation of approximately 99.9%<\/strong> and a cash component of about 0.1%<\/strong>.<\/p>

Technology and AI weighting continues to rise<\/strong><\/h2>

The rotation toward technology continued throughout the week.<\/p>

Following the expansion of semiconductor exposure in the previous week, Micron Technology<\/strong><\/a> and Intel<\/strong><\/a> were increased again. Together, the two companies now account for approximately 24%<\/strong> of the portfolio, meaning semiconductors play a significantly larger role within the UMBRELLA Strategy.<\/p>

At the same time, Palantir Technologies<\/strong><\/a> and SpaceX<\/strong><\/a> were further expanded. This strengthens the focus on artificial intelligence, digital infrastructure, and advanced technologies.<\/p>

Together with Alphabet<\/strong><\/a>, these positions now form an increasingly important technology focus within the strategy.<\/p>

Micron Technology with record results<\/strong><\/h2>

Micron Technology<\/strong><\/a> was among the most important company-specific developments of the week.<\/p>

The company reported record results for the fourth quarter of fiscal year 2026, supported by strong demand for AI infrastructure and data center memory solutions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

Following the results, the position was further expanded and now accounts for approximately 12%<\/strong> of the UMBRELLA Strategy.<\/p>

This development provides further fundamental confirmation for the investment thesis surrounding AI and data center memory, which already played a central role when Micron was added to the strategy in September.<\/p>

Intel position further expanded<\/strong><\/h2>

The position in Intel<\/strong><\/a> was also significantly increased during the week.<\/p>

After being added in September and several subsequent increases, Intel now accounts for approximately 12%<\/strong> of the strategy.<\/p>

Together with Micron Technology<\/strong><\/a>, Intel thus significantly strengthens the direct semiconductor weighting.<\/p>

Palantir and SpaceX gain weight<\/strong><\/h2>

The positions in Palantir Technologies<\/strong><\/a> and SpaceX<\/strong><\/a> were also further expanded.<\/p>

Palantir now accounts for approximately 13%<\/strong> of the strategy, increasing exposure to artificial intelligence and data-driven software.<\/p>

SpaceX was increased to approximately 13%<\/strong> and remains a key component of the allocation in the field of advanced technologies.<\/p>

Together with Micron<\/strong><\/a>, Intel<\/strong><\/a>, and Alphabet<\/strong><\/a>, these companies underscore the increasing importance of technology-related themes within the current portfolio structure.<\/p>

Healthcare weighting reduced<\/strong><\/h2>

While the healthcare sector remains an important component of the UMBRELLA Strategy, its weighting was reduced during the week.<\/p>

Positions in Eli Lilly<\/strong><\/a> and Johnson & Johnson<\/strong><\/a> were partially reduced following positive performance. However, both companies remain part of the strategy and continue to secure exposure to the healthcare sector.<\/p>

Bayer<\/strong><\/a> was actively adjusted during the week. After an initial increase, the position was reduced again following renewed price weakness. Bayer remains part of the strategy with a weighting of approximately 9%<\/strong>.<\/p>

Revolution Medicines<\/strong><\/a>, meanwhile, remains the largest individual position at approximately 18%<\/strong> and continues to represent the largest healthcare exposure within the portfolio.<\/p>

MercadoLibre exits the UMBRELLA Strategy<\/strong><\/h2>

MercadoLibre<\/strong><\/a> exited the UMBRELLA Strategy completely during the week.<\/p>

The position had already been reduced several times due to ongoing technical weakness. The remaining position was subsequently closed completely. The final performance was approximately \u221210%<\/strong>.<\/p>

The exit further concentrates the portfolio on the areas of healthcare, artificial intelligence, semiconductors, and advanced technologies.<\/p>

Outlook: AI and semiconductors remain in focus<\/strong><\/h2>

The UMBRELLA Strategy enters the new week with a more concentrated allocation in the areas of healthcare, artificial intelligence, semiconductors, and advanced technologies.<\/p>

Following the record quarterly figures from Micron Technology<\/strong><\/a>, developments in the semiconductor sector remain particularly relevant. The high weighting of Micron and Intel makes demand for AI infrastructure and data centers an increasingly important factor for the portfolio.<\/p>

At the same time, healthcare positions, led by Revolution Medicines<\/strong><\/a>, continue to provide diversification. Further positioning will be determined by ongoing market developments, company-specific news, and technical signals.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
