A Different Perspective
While it's never nice to take a loss, Shenzhen Neptunus Bioengineering shareholders can take comfort that their trailing twelve month loss of 9.4% wasn't as bad as the market loss of around 11%. Given the total loss of 4% per year over five years, it seems returns have deteriorated in the last twelve months. Whilst Baron Rothschild does tell the investor "buy when there's blood in the streets, even if the blood is your own", buyers would need to examine the data carefully to be comfortable that the business itself is sound. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
