I think we should coin the term 'Veronica' in a trading sense.
Veronica as a noun: someone who buys at a peak and sells the bottom
Veronica as a verb: doing a Veronica is the act of buying at a peak and selling the bottom
The irony is that it would be types like you who would be telling Veronica to buy and hold at $1000. Indeed, it was someone like you who told her to buy and hold at $1000 and she done it.
How about
Veronica as a noun: Someone who heeds financial advice from some Nutter with Kool-Aid foaming out his mouth
Veronica as a verb: The act of getting drunk on 2nd hand Kool-Aid and making investment decisions whilst under the influence.
