SP500 Long Term Model : Remains 100% Long position at 1058.00
SP500 Long Term "Long Only" Model : Went Long the Market 3/30/09 at 787.53

Both have done well this year. The SP500 Long Term Model is up close to 40%. The "Long only" model went long at 787 and the SP500 is at 1080.
I would be very conservative about investing new money into the Long positions these models have right now. The risk is very high.
For the SP500 Long Term Model : I would wait until it gives a sell signal.
For the SP500 Long Term "Long Only" Model : I would wait until the SP500 gets down to the 970 - 980 area.
