If there is a cash call then I will stay in or average down until any negative product new is released (which I hope and assume will not happen).
Rights issues and equity calls are not always doom and gloom, and are often needed to carry a developing company through to the final stages. I know the common belief is directors buying cigars and port and having a great salary on us. But on the other hand if a world leading product has just reached the finish line but cash has run out then more cash is needed to finalise, and to ensure to would be customers that the company will be around.
IMG is good eaxample (IMHO).
