Michael Burry warns investors to reject greed amid parabolic stock rises
With institutional buying pressure evident in major technology names, the Bear Stearns veteran cautions that valuations are being pushed sharply higher by excessive market sentiment.

Michael Burry has issued a stark warning to investors, advising them to reject greed and reduce their positions almost entirely in any stocks experiencing parabolic rises. The prominent investor cited excessive enthusiasm surrounding artificial intelligence and momentum-driven trades as the primary drivers pushing valuations sharply higher in recent market sessions.
This caution comes as the broader market grapples with significant institutional buying pressure in major technology sectors. Reports indicate that heavy accumulation continues in key names, with Amazon shares surging 31.9 per cent in a single month following a fourth-quarter fiscal 2025 report that beat expectations. The company posted revenue of $213.4 billion and operating income of $25 billion, fueling a period of strong investor demand and unusual buy pressure from big money institutions.
While Amazon stock has historically gained over 23,545 per cent since 2002, the current environment is characterised by a specific type of volatility linked to artificial intelligence narratives. Burry's comments highlight a concern that such rapid price appreciation is detached from fundamental valuations, driven instead by the fervour of momentum traders seeking quick gains.
The advice to reduce holdings almost entirely represents a binary recommendation that may not suit all investor risk profiles or portfolio strategies. Burry's directive is framed as a personal view on navigating the current market dynamics rather than a universal financial mandate for all market participants.
Institutions continue to show aggressive appetite for major tech equities, with reports of heavy buying in NVIDIA shares amid strong earnings results. This ongoing accumulation contrasts with Burry's call for caution, illustrating the divergence between institutional accumulation strategies and the warnings of seasoned contrarians.
The term parabolic is subjective and requires clear definition to ensure readers understand the specific price action criteria being referenced in this context. Despite this nuance, the core message remains clear: the current market exuberance around artificial intelligence and momentum trades warrants a defensive approach from investors wary of excessive risk.
