Ann: $37 Million Placement, page-55

If you read back on other threads, people who held SIR complain they sold out too early and won't make that mistake here.
You can't expect people to specifically tell you how to handle this, it's giving advice. That's why people will say if you're unsure, take profits and free ride it.
Obviously if you are sure you will hold on.
There's no easy way solution and I have held for over 10 years because of my respect for Tony R and team, and increased holdings on the anns.
Ultimately you will need to DOYR and carefully read the anns and do some analysis of your own.
Read back is also helpful.
There's no avoiding the DOYR element.
