Who has asked you for this? That might help understand what the problem is
that you are solving.

Did you have a chance to look at the hReview FAQ?
In particular, item #9

Could you provide the parameters that you have been given?

There are a few microformat and hReview fundamentals being violated here.
1. Visible data. The ticker symbol, exchange, country should be visible in
the text as the reviwer would write them.
2. Use XHTML 1.0 following Appendix C - Compatibility. Empty <span/>
elements are not compatible XHTML 1.0.
3. There may only be one "item" per "hreview". I thought this would be
obvious from the spec, but it apparently isn't, and it should be made
explicit. I have added this as an issue to hreview-issues:
4. Simplicity / Solve a specific problem. We try to keep each individual
microformat simple and to solve a specific problem. For hReview, the
specific problem is reviews. Adding stock-ticker-specific semantics to a
review format is neither keeping it simple, nor keeping it specific.
5. Modularity. It looks like what you're actually trying to do (perhaps
should be trying to do) is to invent a new microformat for talking about a
stock (ticker, exchange, country, expiration). If that's what you are
trying to do, please take a look at the microformats process:
and go through the steps of gathering research to see if there is sufficient
reason / usage patterns to create a microformat for stocks.

More violations of #1 and #2 above.

This makes it look like there is a *product* being reviewed, and that
*product* is Time Warner.
That might make sense for the AOL executives who made the purchasing
decision to buy Time Warner, but I don't think that's what you intended.

See above about microformats process.
Before creating or defining a new microformat you must do some research and
document it on the wiki.
