hmmm not sure how I feel about this. I bought Twitter stock after I knew he will be joining the board.

I would give you two pieces of advice.
The first is traditional investing wisdom: buy on rumors, sell on news. Why sell on news? To make money from people who did what you did. Once you hear about some news, it's almost always too late to make money on it.
The second piece of advice is not to trade on anything Elon Musk says or does.
Buy the rumour, sell the news. The time to 'buy' was two months ago. [0]
