Geoff Gannon gives us his answer:
Take your time.
But don’t wait for a market crash.
Just wait for an obviously wonderful business selling for the kind of price a normal stock sells for in normal times.
[Looking back on some of my picks, I bought some good companies (or what I thought were good companies) initially too high, but then bought more as they declined. For example, Costco (which has worked out). Walgreen (which hasn't so far).]
