Follow SportsInsights on Twitter

Investors are seeing red in the financial markets, with the S&P down -7% in September (and down -9% for the year).  Unfortunately, the
Sports Investing Index was down -14.6% during September
, as well.  The Sports Investing Index reached an all-time high in June — but since that time, contrarian sports investing techniques have struggled.  The Index is now down for the year and is at its lowest level since August 2010.

Some Sports Investing Index performance notes:

  • During September, the Index was -14.6% and was comprised of MLB, College Football and NFL sports investing action.

  • MLB results continued to struggle in September.

  • College football got off to a bad start, with this sector contributing -9.3%.

  • The NFL got off to a good start, contributing +5.6% to the Index.

  • October will see NHL action added to the mix.  Please check out Sports Insights’ recent NHL research on “betting against the public.”

Sports Insights publishes a
Sports Investing Index to reflect the performance of applying contrarian value approaches to the major US sports marketplaces
.  The origins of the Sports Investing Index were
published in our book, “Sports Investing: Profiting from Point Spreads.”
