Backtests for Zweig on the JSE are waiting in line like all the rest until we get to them, especially since its a rather complex scan. We would rather focus on the Forward Tests through the Strategy Blogs which will allow our readers to also put portfolios together, but this will require time for us to build the screening engine.
Until we have done JSE backtests, we will be watching the AAII forward tests which have been done over the last 10 years. The latest Zweig performance chart appears below.
You can read more about the Zweig Strategy's overall performance in our research report titled "This decades best strategies" available from the RESEARCH tab.
