Whaddya know. You can still make money off old school ties and inside information – in the United Kingdom:

“… We test the hypothesis that analysts’ school ties to senior officers impart comparative information advantages in the production of analyst research. We find evidence that analysts outperform on their stock recommendations when they have an educational link to the company.

A simple portfolio strategy of going long the buy recommendations with school ties and going short buy recommendations without ties earns returns of 5.40% per year.

We test whether Regulation FD, targeted at impeding selective disclosure, constrained the use of direct access to senior management. We find a large effect: pre-Reg FD the return premium from school ties was 8.16% per year, while post-Reg FD the return premium is nearly zero and insignificant.

In contrast, in an environment that did not change selective disclosure regulation (the UK), the analyst school-tie premium has remained large and significant over the entire sample period.”
