I was looking at Matt's Sell in May and Go Away information, along with the paint dry system trade dates.

It struck me that combining the "Paint Dry" system into the mix would have meant that no trade would have taken place in Oct 2008 for the Sell in May system  - because "Paint Dry" was in CASH in Oct of 2008. Instead of buying at 9065.12 in Oct 2008, that buy would have been postponed until 3-31-09 when Paint Dry went long again.

Sell in May then went to cash on 4-21 09 for a 4.75% gain instead of a -12.08% loss. Hypothetical compounding of that positive result, instead of the 12% loss, puts the compounded total for Sell in May at something like $2,556,888 instead of Matt's hypothetical $2,144,644 that is listed in the data.

Another example of how important it is to eliminate or lessen losses by going to 100% cash at times - something the Wall Street types think is impossible to do successfully.
