Today I just found out that $SIVE is being heavily shorted.

Interestingly: if the stock price continues to rise "unexpectedly," some hedge funds may have to pay a high price.
Colosseum Fund reportedly declined nearly -19.8% last month, mostly due to short positions with Sivers. When a stock is heavily shorted, the risk is no longer on the company but on those betting on a decline.
If the CPO (Co-Packaged Optics) sector truly enters a strong growth cycle in the next two years, and Sivers continues to be valued based on that potential, then short positions could face "unlimited losses" — at least in theory.
What’s notable is that Sivers has never been considered a purely "short squeeze play." Essentially, it’s one of the attractive names in the optical infrastructure and CPO story. However, when a company has a strong foundation but a high short interest, a squeeze effect can occur as a side consequence.
If funds are forced to buy back shares to close their positions, they will have to purchase directly on the market, increasing demand while supply remains unchanged — which could push the price even higher.
In the market, sometimes the story isn’t just about whether the fundamentals are right or wrong, but also about who is standing on the wrong side when the trend reverses.
