Morgan Stanley
A global investment bank and wealth manager with a large asset management arm. Two of its free outputs stand out: the Counterpoint Global papers by Michael Mauboussin and Dan Callahan, which are some of the best corporate-finance teaching anywhere, and the daily Thoughts on the Market podcast from its research strategists.
What they publish
Michael Mauboussin and Dan Callahan's research papers on valuation, competitive strategy, capital allocation and decision-making. These are free, footnoted primers that many analysts treat as a corporate-finance curriculum.
Morgan Stanley Research's short daily podcast, usually under ten minutes, in which its strategists and economists explain one market view at a time. It is an easy daily habit for anyone learning how sell-side strategy works.
