The following is the original content:
Circle this quarter seems like a pig flying high on the high-interest rate trend, but the market is worried the wind direction may change:
Narrowing spreads, rising costs, single-profit business, regulatory uncertainty;
With these headwinds, companies flying high may also be prone to quick falls.

Imagine the stock market as a "marathon-style gamble," where yesterday player Circle rushed through a mid-race aid station (Q3) and achieved a good profit result. However, after investors reviewed the report, they believed that the upcoming slope, player pace, and aid may not be sustainable, leading to selling and causing a price drop.
1) Investors Focus More on the "Future"
Although Circle significantly exceeded expectations in Q3, it also raised its full-year operating expense forecast ($495–510M). This implies that the company's future profit growth rate may be "eaten up," making it unable to achieve high profits again.

2) Reserve Yield Declining
Companies like Circle, which operate stablecoins, make a significant portion of their earnings through:
Issuing stablecoins, users buying stablecoins, and the company receiving dollars to purchase conservative asset investments such as government bonds/short-term notes
Take the spread without paying interest through this method.
A report shows that although the total amount of reserve income is large, the reserve's simple interest return has decreased by approximately 96 bps.
If market interest rates decline or short-term yields compress, this profit-making method will significantly shrink in the future, directly impacting earnings.

3) Income Highly Relies on "Reserve Income"
Out of Q3's $740M, the vast majority comes from reserve income ($711M), while "other income" (subscriptions, services, transactions, etc.) is only $29M.
This means that Circle's current business is more like a large treasury that doesn't need to pay interest to users, rather than a traditional SaaS or payment company;
When the market is concerned about narrowing spreads or regulatory impact, this single-income model will be discounted.

4) Regulatory and Policy Risks
Stablecoins are closely related to reserve assets, and any regulation (such as strict rules from the U.S. Congress/regulators on stablecoins) or on reserve assets (such as restrictions on holding government bonds/short-term notes) will affect revenue expectations.
During regulatory uncertainty, investors often demand a higher risk premium, leading to sell-offs and stock price declines.
In fact, Circle is currently in a delicate stage:
Its profit model is sound, its compliance foundation is solid, but the growth story is losing momentum.
Perhaps in the eyes of many traditional investors, it is more like a "dollar fund company," making safe but unimaginative money.
