I've had an incredible track record in my stocks, and I think that arrogance went to my head on a company SGH which I lost about 30k on. Averaged down (bought more as it tanked) and the company was almost completely destroyed overnight from a bad acquisition and debt pile of a disaster firm they thought they could turn around. Despite reading the accounts and financial reports of the acquisition myself which didn't look good I trusted the management of SGH especially as the CEO owned 25% of the company, and ultimately they were completely wrong and the accountants had no idea what was going on. Tanked about 99% and I sold at 95% down. This was a top-tier market darling which I made 100% on in about a year prior to the acquisition which I held through so still mindblowing what a f*** up management of billion dollar companies on salaries of half a million and above can make.
Made a lot from the FAANMG (Facebook, Amazon, Apple, Netflix, Microsoft, Google) big tech stocks minus netflix which I still think are very strong but not as perfectly valued as they were 12 months ago. Also Magellan Finance in Australia and Corporate Travel Management. Dominos Pizza too which I sold a few years ago close to 10x up.
Lately all the decent money is from crypto. Wish I'd put more in initially, my investment was very small but grew substantially.
