Chew wrote: **"Fund flow data shows a divergence in the market, with aggressive short positioning being built on one hand, while previously accumulated long positions continue on the other.** Bullish positions on the Nasdaq remain elevated, and although the overall landscape has improved somewhat, it remains vulnerable to downside risks." This assessment implies that **if upcoming risk events trigger market disappointment, crowded long positions could spark massive unwinding.** ## Long Positions Remain Elevated, Downside Risks Skewed Over the past few weeks, investors have continued to increase their US equity holdings. Fast-money asset managers, such as Commodity Trading Advisors (CTAs) and volatility-controlled funds, used the window of easing market volatility to rebuild exposure, while news suggesting a potential resolution to the Iran conflict also boosted market sentiment. However, the Citigroup team noted that this round of position rebuilding has not eliminated potential hidden dangers. Chew wrote in the report: "Although some de-risking has occurred, bullish positions on the Nasdaq remain elevated, and most longs are still in profit. This keeps downside risks skewed, especially in the face of upcoming catalysts in the tech sector—any signal that disappoints the market could trigger massive long unwinding, given that profit levels remain high and long positions are crowded." ## Major Risk Events Loom, Pressuring the Market In the coming weeks, US stocks will face a barrage of risk events. **US Inflation Data will be released this Wednesday**, with the market closely watching its implications for the monetary policy path. More critically, **the Federal Reserve will announce its interest rate decision on June 17**. This will also be the first FOMC meeting presided over by new Chair Kevin Warsh, whose policy stance and communication style are drawing significant market attention. At the same time, **large-scale initial public offerings (IPOs) from SpaceX, Anthropic, and OpenAI will also debut sequentially**, directly testing the market's willingness to absorb further expanded exposure to the artificial intelligence theme. Against the backdrop of already crowded long positions in the tech sector, the market reaction to these IPOs will serve as an important litmus test for investor risk appetite. ## European Market Landscape Relatively Stable In contrast, the Citigroup team believes the overall landscape of the European market is more stable. The report noted that short positions in the Euro Stoxx 50 index of large-cap stocks have been covered, and regional benchmarks such as the German DAX, the UK FTSE 100, and the Euro Stoxx Banks Index are gradually returning to neutral levels. Chew stated: "The improvement in positioning is reinforced by better profit-and-loss dynamics, which reduces pressure on existing positions and creates a more constructive backdrop for the recent market." This stands in sharp contrast to the current state of the US stock market, characterized by a divergence between bulls and bears and structural fragility. ### Related Stocks - [C.US](https://longbridge.com/en/quote/C.US.md) - [.NDX.US](https://longbridge.com/en/quote/.NDX.US.md) - [OpenAI.NA](https://longbridge.com/en/quote/OpenAI.NA.md) - [C-R.US](https://longbridge.com/en/quote/C-R.US.md) ## Related News & Research - [Citigroup Targets Stablecoin Rivals With Tokenized Deposits And New Leadership](https://longbridge.com/en/news/288907692.md) - [Summit Therapeutics Announces Proposed Public Offering of Common Stock | SMMT Stock News](https://longbridge.com/en/news/289236576.md) - [These 3 Smart AI ETFs Unlock the Trillion-Dollar Tech Boom Without the Single-Stock Gamble](https://longbridge.com/en/news/289042536.md) - [What's Going On With Hyperscale Data Stock Monday?](https://longbridge.com/en/news/289059671.md) - [A Look At SEI Investments (SEIC) Valuation After Strong Q1 Earnings Beat And Growth Initiatives](https://longbridge.com/en/news/288954747.md)
