Sony to sell $1.9bn of conv bonds, stock down 10% in early trading.

[TheLastStarFighter]

Sony is in terrible shape due to excessive debt. They would be a awful investment. This bond sale is a desperate move, and since it means that either cash will be paid out if Sony does poorly or stock given out if Sony does well (causing dilution) no shareholder should be happy about it. Thus, the stock dropped 10% with the announcement.
