KoGuan thinks all retail investors are on the same boat. At one point he thought he could hold up the stock to prevent the other retail shareholders from being margin called.

I think he is naive to think that way. Investment/trading is not a team sport. It's a tough game and there is no friend or enemy. Everyone should fight for their own survival and prosperity.

If I were him I would swing trade every week to generate extra profit, then use the profit to build index position. Maybe he has been doing this, who knows.

If you are in the investment/trading game, you should focus on one goal: make money and keep money. This is why Warren Buffett doesn't care if it's renewable energy, oil, or coal. As long as he can make a worthwhile profit. A lot to learn from Buffett.
