Tesla was down 12% upon announcement of the deal. I guess if your crystal ball didn't tell you this value-destructive deal was coming, you got screwed.

Non-professionals shouldn't act in the short-term market anyways, at least not if they can't afford to lose 100% (or even more, like Uli Hoeness, who screwed up with leveraged deals).

Just invest in long term - in my opinion Tesla and SpaceX are decent bets. Both won't go under the bus any time soon, I'd rather be concerned about fossil fuel stocks.

One day price bump doesn't matter. If it regains the 12% in a week, to a long term investor it destroyed 0 value.

"If" is the key word that you used. Nothing in the future is promised. See what long term holders of Valeant have to say..it goes both ways. The only thing that is certain is that the stock lost 12% of its value in a single day over acquisition/poor corporate governance concerns. That would be alarming to me as a long term shareholder.

A long-term shareholder that is worried about an announcement day bump must be new to the stock game, or not that good at it.

You're only screwed if you sell. Why would you sell a volatile growth stock during the dips?
