HIPPO (sudeng) fluctuated 50.1% in 24 hours: trading volume surged 65%, amplifying price volatility

After the market opened on Thursday, retail investors went against the trend and bought up Nvidia, with net purchases reaching $111 million in just half an hour, setting a record for the same period. Investors such as Tom Lee have publicly supported the company, with institutions optimistic about strong order backlogs extending to 2028, robust revenue growth, and opportunities created by declining valuations. Meanwhile, institutions like Bernstein and Goldman Sachs have become more cautious about Nvidia's outlook, with concerns focusing on management succession and technological leadership following Jensen Huang's departure.

The market's response strategies to major listings are currently centered around "index inclusion expectations": the new regulations allow mega IPOs to be included in the six major indices within 15 days, triggering concentrated buying by passive funds. Investors are positioning themselves in advance and using options to hedge and amplify buying power. However, Anthropic has a free float of only about 6%; shares available for sale by employees on the first day and privately placed shares with no lock-up period may create supply pressure. On the other hand, index arbitrageurs are facing a rare opportunity.
