I'm new to this forum, but thought it was TSP (not corn futures) talk? Anyway, I've been following markets since 1995 (new on this forum, not new to trading) and here's my take as we stand now:
F Fund: I've never like bond funds (yechh), but the yields on long term treasuries have hit the upper trendline of a twenty years' long parallel downchannel several weeks ago. Other indicators also confirm that strong long-term resistance (to a rise in _yields_) has held. We're short-term oversold (again, referring to yields) and due for a bounce. Any such bounce would be a good opportunity to shift some allocation into the F fund (as I plan on doing over the next few weeks).
It's interesting what the above means. Note the significant inversion we have on long term yields vs. short term. The bond markets (which are huge and whose participants are smart money) are flashing: slow down (perhaps recession) ahead. Like I wrote, I don't even like bond funds, but it's not about like, it's about being obective. That channel held, and the bottom of that channel would put yields well below 2%... yeah, crazy, but there it is.
As for the stock funds -- I have had multi-month sells since May; intermediate (weekly is unclear), but now new short-term (daily) sells after Wednesday's short-term buys. Not as clear as bonds -- choppy with buy and sells flipping. But, it looks like that choppiness is about to end. Many seem to think that the end of a fed rate hike campaign is a green light for stocks -- it's not. 2000 was also the end of a series of hikes.
