The in-box this morning delivered a link to an ebook that you must read if you’re marketing investment products. Tradestreaming and the Future of Investing is a 23-page compilation of multiple commentators’ view on “what’s happening online for investors and how investors stand to benefit.”

The ebook was put together by Zack Miller, who we know as the author of the newrulesofinvesting.com blog but who also is the managing director of a boutique investment firm. His official biography says he “embodies the nexus between asset management, equity research, and new Internet distribution technologies.”

We “met” Zack on Twitter and are honored to have our few paragraphs include among commentaries from individuals representing businesses that are changing the work you do and its effectiveness.

You need to read what kaChing, SeekingAlpha, wikinvest and the others have to say and what it means for your business. We suspect that Zack’s selection of contributors and the perspectives they provide will push you and your firm to think more broadly about this ongoing online finance revolution.

Publishing the ebook is a smart way to promote today’s launch of Zack’s book Tradestream Your Way to Profits: Building a Killer Portfolio in the Age of Social Media. If Zack’s curation of the ebook is any indication, the book will be well worth a read, too.
