Sun Stock Prices

Sun Microsystem’s (NASDAQ:JAVA ) hit a low this week of $8.71. There was a stronger rally and a close at $9.16 today. The financial times reports Sun Micro chief sees rays of hope , and Bloomberg Sun Rises After Fourth-Quarter Profit Tops Estimates .

I cashed out in March at $16.32, so that’s like a 50% drop in share price. I was lucky having been at MySQL long enough to have options to vest. Newer employees are not that lucky. I certainly hope MySQL Sun Employees get the Q4 weighted bonuses. (A structure I didn’t believe compensated with the old bonus structure).

I have been following more closely since Matt Asay’s comments in Who is buying Sun?

It is the appropriate test when the population parameters are established — quality control benchmarks, national averages, long-run process measurements — and you want to evaluate whether a new sample is consistent with them.
