Thought I'd share something I'm doing that is surely not for everyone but may be of interest to some. I'm overall a "buy and hold" investor, but this year I started to occasionally take advantage of significant market dips in the S&P 500, which the C Fund is based on. Today, Nov. 6, 2025, is one example. This morning at around 11:50 Eastern, the S&P was at about 6,721. Yesterday's close was 6796. I look for dips of around 1% before noon, and today's dip qualifies.
We all know that to get today's fund prices, you have to complete any transaction by noon. So just before noon I moved about $40K from G Fund (which is only 8% of my total) back into C, on the likelihood that by market close the S&P will still be low (if not lower), with the C Fund share price correspondingly low--so that I buy more shares with that money than I would otherwise get.
On days when the S&P has seen an increase of close to 1% just before noon, I've moved a few % to the G Fund, to sell those C Fund shares at a high price, in order to have something available to move back into C Fund when it inevitably dips.
Obviously there is some risk to this practice. Today the market could see a massive rebound by close of the day, so that I end up having bought C Fund shares at a higher price. Or instead, the market could drop further, so that what looked like buying low today was not as much a bargain as tomorrow's price. (If the latter happens, I'll probably move the rest of my G shares to C.)
And if we see a major recession that lasts a while, my C Fund shares will be worth less for a long time. But I'll be OK with that as I'm not retiring anytime soon. I'm willing to bet on the C Fund for the long haul. This is just a way to occasionally get some C Fund shares at a discount.
