Ackman buys Microsoft as Loeb exits the stock for Alphabet

What happened

A notable divergence in investment strategies from two prominent US billionaire fund managers, Bill Ackman of Pershing Square Capital Management and Daniel Loeb of Third Point, has captured the attention of global financial markets. Their recent portfolio adjustments in major technology stocks, specifically Microsoft and Alphabet, highlight contrasting views on the future performance and valuation of these industry giants.

Ackman's Pershing Square initiated a substantial new position in Microsoft, beginning its acquisition of shares in February. This move followed a significant price dip after the tech behemoth reported its fiscal Q2 2026 earnings. Ackman publicly indicated on X that Pershing Square was able to establish its position at a valuation of 21 times forward earnings, which he noted was broadly in line with the market multiple and considerably below Microsoft's historical trading averages.

Conversely, Daniel Loeb's Third Point divested entirely from Microsoft during the same quarter, ending a stake it had held since late 2022. Simultaneously, Third Point reportedly increased its holdings in Alphabet. This contrasted sharply with Ackman, who not only reduced but later entirely exited Pershing Square's position in the Google parent company. Interestingly, both funds did open new positions in Meta Platforms during Q1, indicating some shared outlooks on other tech areas.

Why it matters for Australian investors

While these investment decisions originate from US-based hedge funds, their implications resonate globally, including within the Australian investment landscape. Australian investors often have exposure to these major US technology stocks through diversified portfolios, superannuation funds, or direct investments via platforms like eToro, Stake, or even traditional brokers that offer access to US markets. The movements of large institutional investors can signal shifts in market sentiment and fundamental outlooks, potentially influencing broader tech sector performance.

For Australian super funds with significant international allocations, a re-evaluation of big tech stocks by influential figures like Ackman and Loeb can prompt internal discussions about their own portfolio weightings. Even for individual 'mum and dad' investors, tracking such developments provides valuable context. If these large-cap US tech stocks experience significant volatility, it can indirectly affect the Australian dollar (AUD) if foreign capital flows shift in response to global risk sentiment.

Furthermore, the narrative around artificial intelligence (AI) and cloud infrastructure, highlighted by Ackman's rationale for Microsoft, is pertinent for Australian technology companies and the broader economy. Growth in these areas could generate opportunities or challenges for local tech firms and investment into related sectors. The tax implications for Australian investors holding international shares, including capital gains tax treatment from the Australian Taxation Office (ATO) upon sale, remain a crucial consideration when observing such market movements. Investors should always consult ATO guidelines or a financial advisor regarding their specific tax obligations.

Impact on the AUD market

The direct impact on the AUD market from these specific trades is likely to be indirect, primarily through shifts in global investor sentiment towards the broader technology sector. If these investment moves contribute to a significant rally or correction in major US tech stocks, it could influence risk appetite globally. A strong performance in the US tech sector generally fosters a 'risk-on' environment, which can support the Australian dollar as investors seek higher-yielding assets or commodity-linked currencies.

Conversely, if these divergent views lead to increased uncertainty or volatility in the US tech market, it could contribute to a 'risk-off' sentiment. In such scenarios, the AUD typically weakens against safe-haven currencies like the US dollar, as investors move capital out of riskier assets. As Australia's financial ecosystem, including major banks and investment firms, has considerable foreign exchange dealings, these sentiment shifts can translate into movements in the AUD/USD pair, affecting everything from import costs to the purchasing power of international investments for Australians.

Moreover, Australian technology stocks, particularly those with global aspirations or dependencies on cloud services from giants like Microsoft and Google, could see indirect effects. While not directly linked to cryptocurrency markets or regulated by bodies like AUSTRAC or ASIC in the same way, the overarching financial market sentiment can affect all asset classes, including the nascent Australian crypto market. Stability or volatility in traditional equity markets can influence how Australian investors allocate capital across the spectrum, from established stocks to digital assets traded on local exchanges such as CoinSpot, Independent Reserve, Swyftx, and BTC Markets.

What to watch next

Investors tracking these developments should pay close attention to the unfolding narratives around AI and corporate capital expenditure. Bill Ackman's commentary on Microsoft's substantial projected capital expenditures – approximately $190 billion in 2026 – for expanding data centres and AI infrastructure is a key data point. His view that this spending represents long-term infrastructure investment rather than mere short-term cost pressure will be tested as Microsoft reports future earnings.

Further earnings reports from Microsoft and Alphabet will be crucial for validating or challenging the investment theses of Ackman and Loeb. Microsoft's ability to monetise its significant investments in AI, including its economic interest in OpenAI, and the continued strength of its Azure and Microsoft 365 franchises, will be under scrutiny. Similarly, Alphabet's performance, particularly in advertising and cloud services, will show whether Loeb's increased exposure proves prescient.

Beyond specific company results, the broader economic environment, including global interest rates and inflation, will also influence the performance of growth-oriented tech stocks. For Australian investors, monitoring how these US tech giants navigate the competitive landscape and regulatory pressures will be key. Any major shifts in their market dominance or profitability could have ripple effects that reach Australian shores, affecting investment strategies across various asset classes, from traditional equities to the rapidly evolving digital asset space.
