You still don't seem to understand. A private placement is a way of raising capital. Particularly for development companies, this is absolutely vital. It makes the company's success more likely, not less likely. Would you really rather they did not raise funds and simply go under, thereby sending your investment to zero?
The private placement did not cause a sell off. You and others may have by misinterpreting it and making incorrect assumptions and continually harping on it like it was strange or unusual or damaging to the company, when the opposite is the case. Probably 90% of the companies discussed on I-Hub have done private placements as do many large corporations.
