If I were Worried I would not be adding and instead I would be setting out a LIMIT order sell at 5% over my current average in order to pull out any amount of money I deemed as "too much" and I would be leaving that order open for 30 days. I use 5% over average on orders such as that as I would want some sort of return on the investment that beats my savings account, 7% would be enough to beat current inflation rates.
I partial sell over average would rebalance the investment to a lower cash balance but would also result in a lower cost per share (lower average) than prior to the rebalance.
You can play around with that approach with various targets to see how that actually works.
As it stands I am still picking up shares as cheap as I can but not advertising my pending trades
Best Regards,
