Should You Invest in the Most Popular TSP Funds?


When it comes to investing, do you follow the herd?  Most TSP investors do.


Investopedia describes this herd instinct as a “lack of individual decision-making…causing people to think and act…as the majority of those around them.”

Popularity vs Performance

In our last two blog posts, here and here, we mentioned a recent TSP audit. It showed that TSP investors put 75% of their money into the C and G Funds.

This is clearly herd behavior. But is there a good reason for it?  Do the C and G consistently outperform other TSP funds? No—not at all.

The chart below shows how many years each fund has had the highest annual return.  It starts in 2001.  We chose that year because that’s when the TSP added the I and S Funds.

Don’t follow the herd

The I, S and F Funds have clearly been the top performers since 2001. To its credit, the C Fund had the best return in 2014. However, this was its first “top performer award” since 1998. The G Fund hasn’t had the highest return since 1994.

Will this trend continue? No one knows. The point is that fund popularity has nothing to do with fund performance. If anything, you’d do better by going against the crowd.

And the least popular fund is…

The audit showed that the F Fund was the least popular. TSPers put ten times more money into the G Fund than into the F. Yet the F Fund outgained the G in 7 of the last 8 years.

Some people avoid the F Fund because interest rates are at historic lows. Interest rates and bond prices move in opposite directions. Therefore, it appears the F Fund has little room to move higher.

Instead of speculating on such things, it’s better to follow the trend. As long as the F Fund is moving up, it’s a logical choice when the stock funds (C,S, I) aren’t doing well.

The I Fund

The I Fund isn’t popular either. Some avoid it because it has unpredictable daily fluctuations.

This affects very short-term traders. If you hold the I Fund for a month or longer, it’s not a concern. The fluctuations cancel each other out.

So what should you do?

Does this mean we should only invest in the I, S and F Funds? Certainly not. But you shouldn’t avoid them, especially if their trends are stronger than the C and G Funds.

The moral of the story? Don’t follow the herd. Instead, follow the funds…the best-performing ones, that is.

3 Mistakes TSP Investors Make

Let’s face it–investing isn’t easy.  Every day you hear conflicting reports from the financial world.  Friends, co-workers and experts recommend completely different investing approaches.

In this day of information overload, clear thinking is in short supply.  As a result, it’s easy to be indecisive.  It’s also easy to make a lot of poor decisions.

When it comes to the TSP, we often see three particular mistakes:  

  • Keeping a large permanent allocation in the G Fund
  • Avoiding certain TSP funds, even when they perform well
  • Following an adviser or strategy based on short-term results

In future posts, we’ll cover each mistake in detail.  For now, let’s go over the main points.

G Fund overload

A recent audit by the Federal Retirement Thrift Investment Board revealed that almost 45% of TSP assets were in the G Fund.  What’s worse, young people like the G Fund more than baby boomers.

Is it always wrong to put your money in the G Fund?  Certainly not.  In a bear market, it’s a smart move.  But stocks have moved up sharply since early 2009.  The C and S Funds have more than doubled their values since then.

Choose your funds wisely

While the G Fund is adored, other funds are shunned.  The F and I Funds are the least popular.  Maybe you’ve avoided them yourself? 

Hopefully not.  From 2004 to 2007, the I Fund was the strongest performer–by a large margin.  The F Fund had the best returns in 2008 and 2011. By contrast, the G Fund hasn’t been the top performer since 1994. 

What have you done for me lately….or what have you done for me long-term?

Chasing short-term performance is the last major mistake.  Imagine you can choose between two investing strategies:  

  • Strategy 1 has done very well for the last 15 years.  It’s been mediocre for the last three months, however.  
  • Strategy 2 has doubled the stock market’s return for the last three months.  But it only has a 2-year track record, and didn’t perform well until recently.  

Which sounds better to you?

The logical response is Strategy 1. Short-term results are just noise in the long-term picture. Yet some people choose a strategy/adviser based on the last 3 to 12 months of performance. It’s tempting to focus on recent activity, but years of performance is what matters.
