System...ebbtracker..tsp prices
C-fund......+3.62%.....+2.79%.....+1.90%
S-fund......+3.79%.....+3.53%.....+3.76%
I-fund.......+4.29%.....+2.01%.....+4.61%
The System is comprised of the ebbtracker's tracking of the funds with cross-checking function. I included the C and S-fund to see how they do with X-checking. The gains for the C/S-fund got better 'cause it gets to jump on the I-fund when blocked with a stop sign. Conversely, the System using the I-fund gets to go to the S-fund when blocked. One note, the System gets to jump to stocks only when two green signs are showing. Otherwise, it goes to the G/F-fund.
The regular I-fund is tearing it up (+4.61%), but one mistake is all it takes for the System to overtake it.
