- For what seemed like good reasons the regulators put a greater separation between banking and research activities. The more intelligent path would have been to further tie analyst compensation to the aftermarket performance of companies post an IPO to ensure that any analyst supporting a deal coming to market will lose compensation if the company fails to meet or exceed their estimates in the first year. But the SEC cobbled the “solution” under the advice of the criminal firms rather than asking any of the honest ones for guidance.
- That might have been okay but it was surrounded with a bevy of rules and procedures tied to a wave of “compliance” investments that basically drowned any valuable research and content in pool of inane rules and procedures. It even dictated the bland, inconclusive and disclaimer-laden style that most any prospective reader would be repulsed by. Stock ratings, valuation and covering news took center stage despite the fact that institutional investors see them as useless.
- Separated from banking most commission firms felt that research should start doing more to drive votes and business so analysts were given regular marketing duties ranging from daily phone calls to dedicated marketing trips to spend time with customers and get them to like/vote/pay for the research team.  Not surprisingly the amount of energy available for research dropped off just when more was needed thanks in some small part to Regulation FD.
- Regulation FD (Full Disclosure) removed one unfair advantage analysts had with public company managements but it came at the cost of getting little or no useful information from management teams. The dysfunctional aspect of this “rule” is that senior management says far more to a prospective customer than they do to a prospective investor. It’s a clear violation of Regulation FD but it goes on every day. It just means analysts need to work harder and get their information from better and more diverse sources.
- Like other declining businesses the broker/dealer/banks cut their budgets, causing a decline in talent and quality which led to more lousy results and cuts. Before the big decline many of the best analysts went to the buy-side where the value of good research can be still monetized thanks to attractive asset management fees. (This may be less true today but up until two years ago the buy-side has been in a much better position to hire top quality research analysts.)
It’s a long story. The truth is it started fading while it was still growing in importance. The first culprit was investment banking. Stock trading commissions were something like 5c per share while investment banking deals offered $1 or even more per share. No wonder people were distracted by the money. Successful sell-side analysts not only starting getting paid big money for deal-related research but some even started getting pre-IPO shares in companies they were helping to bring public on the basis of their “research” efforts.
If the story ended there the research we knew and loved would have returned after the banking cycle and market excesses were over.  However with the crash came a whole raft of new regulations and practices that made sure that good fundamental sell-side research would take a long time to reappear.
