I think as a relatively new Drupal developer, you could benefit tremendously from getting to know CCK. This will allow you to have flexibility with how fields are laid out and ensure that page layouts remain consistent.
The way you've approached the task, I can think of two ways to get that ticker to show: using jQuery and using a theme function. If you know about
template.php and theme overrides, I'd recommend that route. Otherwise, this should be doable with jQuery:
Place this in a js file:
$('#block-quicktabs-fundsperformancetabs h2').append('<div class="ticker">MSILX, ETC</div>');
And in your stylesheet
Be sure to include your js file in your theme's info file.
scripts = js/custom.js
This has the downside of being 'in the code' instead of editable by the client, but that's where CCK would come in.
