Missing an opportunity is losing money.
I was figuring on a 10% correction, figured I would get out save that 10% of value and get back into the C fund at a 10% discount.
I made out some in 2008 with this strategy.
Assuming you think this is an actual correction, I think your strategy makes sense. Where we differ is that I don't see this as a major correction, but rather just a bump in the positive slope. The market still has a lot of juice to give from easing, IMO. I'm not making any allocation changes and am planning on riding it out for a bit longer. I typically make rebalancing changes in December of every year, so I'll start thinking about that while in my easy chair fighting off the tryptophan-induced coma on Thanksgiving night.
I don't really understand what was wrong with mama's advice. She may otherwise be crazy, but if you're looking to make small bumps like this into "opportunities", I wouldn't be risking as large a chunk of your assets as it seems you are. I'd view that as relatively high-risk money. Of course you know your strategy better than anyone else, so I assume this is consistent with your personal risk/reward model.
To that end, I have a (relatively small) percentage of my portfolio set aside specifically for things like timing moves or to mitigate any downside I'm facing. For example, looking at GOPRO as a short to cover less-than-expected to-date returns for. I bought some at just under $40 and sold at the first $90 crossing. It's then tested the resistance a second time, and retreated slightly. I don't know what the "C fund" is or how it operates, but I have to consider taxes and transaction costs on every decision I make. You may not have that constraint.
The thing about GOPRO is, I think fundamentals are solid, but I'm not sure I ever saw support beyond $60/share. You and DoWhat look at the chart and give me your thoughts.
