Google Finance Technology Summary Bug
More interesting than their streaming quotes coloring bug, today I signed on to Google Finance to see that Technology took a hit last night, down -250141000.00%:
The problem is the ticker ASML (ADR), which appears to be suffering from integer overflow. The ticker (according to Yahoo finance) just changed to ASMLD, and Google probably got a near-0 floating point value for the price that caused its asymptote to spike. Or at least that’s what I hope for a stock with a price of $9,223,372,036,854,775,807 and market cap of -9,223,372,036,854,775,807. Here’s a link to the quote for this symbol.

I found another one. I have no idea where to report it. NYSE:PEG did a stock split today and the change is listed at -52%. The graph however has taken the split into account. I hope this error doesn’t seep into other aggregated values.
