  1. Hey, thanks for your guide! It really helps a lot to understand the Thrift Savings Plan, especially for starters like me.

    Been in the military for almost 3yrs (USN), 24yrs old, and to be honest I’ve been recently concerned about my financial stability and future (concerned not in a bad way), just being responsible I guess?

    Been working on CDs, investments, small family business, and now my TSP.
    I’ll make sure to read more of your guides and other resources.

    Thanks again!

  2. Great blog! Wishing I had found it 3 years ago, glad I didn’t find it 20 years from now! Anyway, I was curious if you had a resource recommendation that could help me select sound non-TSP investments for my IRA and other accounts? Thanks!

  3. I wish I had started it three years ago! In an effort to keep things very simple, my IRAs are typically invested in the Vanguard equivalent to the TSP Fund(s) in which I am currently invested. I think I have all of those identified somewhere in the various posts on the site, but I will make a point of pulling together a list under resources in the near future and noting those funds in future updates.

  4. As a young fed I very much appreciate this information. It’s been a great year for me and you’ve inspired me to increase my tsp contributions significantly when I know plenty of my colleagues haven’t made the effort yet. Keep it up, it’s much appreciated and the insight is invaluable.

  5. Just found your blog. The information is presented in such a way that even a caveman can benefit from your work. It is obviously a labor of love for you, and I am grateful that you share your knowledge with those of us that need a little coaching. I will be sure to share, and I hope your blog reaches thousands. Thanks!

  6. Been using a S&P 500 moving 200/40 average to determine when to get in and out of equities (c/s/i). Has worked well, but I do tend to get out later than I’d like as well as going back into stocks late missing some early gains.

    Thanks for creating this site. It really opened my eyes to a more intelligent way of TSP trading.


  7. Congrats on your 38.35% return!!!! I moved a lot of funds back and forth before following your Twitter feed…. but since then, I kept all my funds in S fund and the rewards are great. Thank you!

  8. Very helpful. Especially for new government employees just getting started with retirement. I’ve emailed your link to multiple coworkers. Keep up the good work.

  9. I look forward to your updates every month and have gained a great deal of knowledge from them, not to mention awesome returns. thank you for sharing.

  10. Bro,
    “Here are the final returns for the month of April. The S-fund is clearly lagging and is clinging to a positive return for the year.” (0.17% up for the year, down -2.47%)

    Wouldn’t ya know, just as I implemented your strategy. “Hang on in there, Baby…”

    Take care

  11. Just wanted to express a moment of gratitude for your time. This is a great site and I very much enjoy your suggestions and insight. While I may not impulsively react to your updates financially, I don’t think you had ever intended on that to be the case. I use your site as a main source of information and I can not thank you enough for offering the information you do. From your generosity, I am always better equipped to make a more informed decision on ALL of my investing, but particularly my TSP. Please keep it going, thanks again!

  12. Stumbling upon this blog is like finding an oasis in the desert. I have intuitively followed your approach since the 90s, and it has rewarded me immensely, though, like Ron (above), I have, during the last downturn in the stock market, gotten out and gotten back in a little later than optimum. I am almost 4 years retired, so I no longer can make new contributions, and, because I draw a healthy CSRS pension and have had other strong investments, I will not draw on TSP until it’s mandatory, and that is over 7 years away. Unlike my peers who all have 100% of their allocation now in the G fund, regardless of their financial circumstances, I currently am fully invested in the S Fund, but keep an eye on the markets daily. Because I have just discovered your site, I have not had time to explore this yet, but I’m hoping you have some advice for those of us who continue to manage our investments in the TSP in retirement and are constantly confronting nay-Sayers who think we should be playing only the most risk-free game possible.

  13. I learned a long time ago it’s far easier to preserve existing capital in the TSP fund than it is to rely on the myth of dollar cost averaging, which robs you of the power of compounded returns from your fully valued portfolio. There is absolutely no reason to throw away hard earned equity when funds are losing money. Place your money in the G fund and wait it out, at zero cost. If you are still in the S fund you just don’t get it. There is no reason not to preserve capital and keep it working for you during a bear market, then get back in on the upswing. Remember: preserve capital at all costs, get a return during a downswing, buy low and watch it grow, go to the G fund when the bear comes back. This is the simple beauty of the TSP funds; moving money around at no cost.

  14. Hello. I am new to the federal government and am many years away from retirement. I have read a lot of your writing and it is a great help to someone who is new to this to have a lot of information to read. I was wondering if you have any specific resources for anyone who is at the very beginning of a hopefully 30+ year career with TSP. Thanks in advance for any help you can provide!

    • David,
      Welcome to the federal government! I’ve been working for the VA for 3 years after serving 20 yrs in the A.F. If there is one thing I wish I would have done at the beginning of my A.F career, it would have been to invest as much as I could as soon as I could in theTSP. I got started late (at age 40) so I have I have to invest more than someone who got started investing in their 20’s or 30’s. The books that got me interested in investing were: “The automatic Millionaire” and “the Millionaire next door”. Good luck!


  15. I’m 48 and eligible to retire in 2024 although realistically probably won’t be able to afford to do that. I’m naive when it comes to retirement planning and the market, but right now I’m 100% in the TSP S fund. Was just reading about the Roth option and wondering if I need to keep my 5% in the TSP S and also allocate a percentage to Roth as well. What are your thoughts?

    • I don’t believe tax rates are likely to be higher overall when I start withdrawing from my TSP in another 15 years or so. And I don’t believe that my various sources of income at that stage will be enough to push me into a higher tax bracket (and I might well fall to a lower bracket), so I have elected to stay with the traditional TSP. If you haven’t seen it yet, I have a whole post here on the Traditional vs Roth TSP subject.

  16. As for the Roth TSP option, I find that the advantage of having all your gains on Roth contributions becoming tax free upon withdrawal well outweighs the disadvantage of paying tax on the contributions now and also having to wait until 59 1/2 to withdraw. Just my opinion…

  17. Hi TS Paul…
    Just a quick note of gratitude…PIP is at 11% for past year using the information I learned from reading the Guide…would be more if I could develop a higher risk tolerance, but I’m happy and still RETIRED!!! You are truly a gift. Thanks again…
    Ron C.

  18. I just wanted to quickly say that I really appreciate you taking the time to run this website. I have read through every post, and really look forward to each update. I have also shared it with my federal co-workers.

    I was always an above average investor, but this website and your analysis have helped me to become even more effective due to a better understanding of the business cycle investing strategy. It has helped me with both my Thrift Savings Plan and other investments.

    Again, thank you. Your work here is appreciated by many.
