TSPinvestor Basic, Plus and Apex .. what are they?

The TSPinvestor has three investment allocation strategies – called the Basic, Plus, and the Apex. These are formulas that recommend monthly Thrift Savings Plan allocations for the individual G, F, C, S and I funds.

A simulation of implementing the Basic, Plus and Apex was done and the 10-year annual return (2005-2014) for the Basic was 12%, the Plus was 19%, and the Apex was 23% (see the comparative annual returns here).

The following link is to a third party site that I use to accurately capture the allocation returns. I have been using this since Dec 2015. So while the data thus far is limited, it is a confirmed and accurate accounting of the performance of these funds. I do recommend checking this out.

The development of the model and formulas relied upon a human decision. But these models are not tweaked or adjusted, nor is there any human decision regarding the monthly allocations.

DEVELOPMENT

The Basic has a model/formula that is solely based upon historical returns of the TSP G, F, C, S and I Funds. The Plus model/formula is based upon historical returns of the individual TSP funds, as the Basic does, but also includes several leading economic indicators.

The Basic, Plus and Apex models, and formulas were derived using mathematical and statistical techniques. A full compliment of factors/variables were considered and selected based upon their effect on matching the historical data. The historical data used was from January 2003 through the present.

The Basic uses only the TSP fund historical data to feed the model/formula. The Plus additionally uses three leading economic indicators. And the Apex uses the Plus model – but then determines if it’s optimal to invest 100% in the top allocation recommendation for that month.

Is It Right For You?

The decision to allocate your TSP account is a serious one. The strategy to allocate (buy) and then don’t change (hold) comes easy, and often is very predictable over the long run. For example, an aggressive strategy in the mid 2000’s to invest 50% in the C Fund and 50% in the S Fund over the course of 12 years yielded about 8-9% per year, which is a fairly good return on your investment. However, there is no doubt that the monthly allocation strategy will yield a higher return. And the risk is less than the aggressive buy and hold strategies, such as the example above.

IMPLEMENTATION

The first step in implementing the TSPinvestor strategy is to choose which fund is best – the Basic, Plus or the Apex. At first glance the 19% return of the Plus, or the 23% of the Apex seem obvious choices. However the 12% return of the Basic may be your choice. Look at some historical data to help decide. Either way, pick one and stick to it for the long term.

The implementation of the allocations is done on a particular day of each month. The Basic is allocated on the last business day prior to the 2nd of the month; The Plus and Apex are allocated on the last business day prior to the 10th of the month. The recommended percentage for each fund should be changed within the TSP website for the fund distribution (via interfund transfers) and also future contributions.

  1. So for example, this month we would have submitted the IFT before 12 noon on Monday the 9th (allocation takes place at the open of the 10th)? Or you do the IFT so you are invested (in the plan allocation) on the day before the 10th, meaning you IFT by noon 11/6/2015? Hope this makes sense… Thanks!

    • That is correct, do the transfer on the morning of the 9th, for November, as it turned out. I have the allocations available on/before the evening of the 8th each month.

  2. Hard to believe these numbers. Especially 2009. Will be watching this closely. You seem to beat all returns for any TSP investment website. Certainly the one I am using.

    • I agree thoroughly. I too am skeptical. And hence my reason for proving they work. I do have some reason to believe they will work like they did simulating the past. This method is very similar to others that have done the same thing. And what they advertise is that their results were very similar to the past simulated results.

      At this point I’ve seen results since November. I’m not totally impressed. But I’m not disappointed either. The results thus far are in the ball park of expectations.

      And when I compare the Plus performance against what I used for 10+ years (held 50% C; 50% S), I am doing slightly better being in the Plus (which is actually what I’ve been doing since October).

      Cheers, Jeff
