TSP Tactical Outlook – September 2026
A Monthly Market Perspective for Federal Employees
The stock market enters the latter portion of September with the longer-term technical picture remaining constructive, despite the recent increase in short-term volatility. The major stock indexes continue to trade within established longer-term uptrends and remain comfortably above their rising 200-day moving averages. Although several areas of the market have experienced normal corrective activity, the underlying technical structure continues to favor the bulls.
One of the more encouraging developments has been the improvement in several momentum indicators following the recent market pullback. Rather than becoming excessively extended following the summer advance, a number of technical indicators have moved back toward oversold conditions and important areas of trend support. This type of reset can be healthy during an established uptrend, particularly when longer-term price support remains intact.
Investor sentiment has also become considerably more cautious. The CNN Fear & Greed Index recently declined deep into the Fear Zone before beginning to recover. From a contrarian perspective, elevated investor fear can sometimes provide a favorable backdrop for equities, particularly when it occurs while the broader market remains technically healthy. The combination of improving momentum and continued investor caution could provide the foundation for another market advance if buyers continue to return.
Within the Thrift Savings Plan funds, the C Fund continues to maintain its longer-term bullish trend despite recent consolidation. The S Fund has also experienced short-term weakness, but its longer-term technical structure remains constructive. Small-cap stocks continue to offer considerable upside potential should market participation broaden and investors become more willing to assume risk.
The I Fund remains particularly interesting from a technical perspective. After pulling back from the upper portion of its long-term trading channel, the fund recently tested channel support and has begun to rebound. The fund has also recaptured its 50-day moving average while remaining comfortably above its rising 200-day moving average. Momentum indicators have reached oversold or near-oversold conditions and are beginning to turn higher, suggesting that the recent correction may be nearing completion.
The F Fund continues to present a considerably weaker technical picture. On an unadjusted price basis, the fund remains within a declining trading range and has yet to demonstrate a convincing technical turnaround. Until the bond market provides clearer evidence of renewed strength and can overcome important resistance, we continue to believe that stronger opportunities remain elsewhere.
Our investment philosophy remains unchanged. We do not attempt to predict every short-term market fluctuation or react emotionally to daily headlines. Instead, we rely on price, trend, momentum, relative strength, and other technical evidence to determine where the strongest opportunities exist. Periodic pullbacks are a normal part of every bull market and can often improve the risk/reward environment by reducing excessive optimism and allowing momentum indicators to reset.
As we move toward the final quarter of 2026, we will continue monitoring the technical condition of each TSP fund closely. Although short-term volatility may continue, the longer-term evidence remains generally favorable for equities. Until the charts indicate a meaningful deterioration in trend, we believe maintaining disciplined exposure to the stronger stock funds remains appropriate while continuing to avoid areas displaying persistent technical weakness.
