Interesting insights. He's a right to his opinion, but my experience is in disagreement with his assessment about "systems". A system simply means a systematic approach or strategy to attain specific results. I'm sure most of the profitable stock and commodity trading houses are using some type of system.
The amount of inspiration, in GME's story, is limited. Whole situation was anomaly. Few got lucky, majority lost socks. The percentages are worse than in Pareto's Law, i guess. There's many interest from institutionals, to make sure that stories like this, the Big Short, HODL TSLA calls to $6 mil & etc, burst the imaginations of young HOOD users.
Looks like he just got lucky with volatility on his side. Usually when you buy options (it looks like that's what he does predominantly) with such long DTE, without volatility on your side, you will get crushed with the volatility crush and the time decay.
There's nothing...inspirational....that comes out of that WallStreetBets forum. Average guys, who make bold, bold, bets and assumptions. And .472% of them will magically hit it big....and brag about their divine, intelligent, story of newfound riches. A four year success story. Someone can have a two week success story...by trading 8 times to double their money to a million. and doing that every two weeks to finish the year with 20 million, more or less. That, unequivocally, is not luck. Instead of long options, weeklies which are more volatile. Someone can, hypothetically, even make a million per day. And do that over, again.
You have to have a trading system or method to deal with various situations that will occur during your trading and how you would handle such situations. Otherwise, you would a discretionary trader or shoot from the hip, rely only on your guts trading. More than likely, you will never achieve consistency as a trader. One trade you are a genius and the next couple of trades, you could be a doofus. Even trading using an algorithm, uses rules or a trading system to determine the next course of action when a situation turns up.
Cathie Wood had a system. It worked until it didn't. Also buying crypto on dips is a system. It had worked for 10 years, then in November it stopped working.
