Record every return to profitability

I’m an old “jiucai” investor; I opened my account in 2006. My first stock opened with was an ST that was going to be delisted—the STs were Wan Jie and Precision. Precision has already been delisted. Wan Jie is today’s 600223 Furuida.
Along the way, I’ve participated in share reform, trading suspension and resumption, re-listing, restructuring with share reduction, warrants, and then later convertible bonds, options, and arbitrage with funds—of course, stocks have always been the main focus.
My trading strategy has gone from ST at the beginning, to S, to value investing, to blue chips, to convertible bonds, to micro-cap stocks, and now to the “large pendulum” approach. I’ve been losing and then winning, and then losing again—but it seems I’ve had decent luck. Even in 2008, the drawdown was only 40%. In 2015, when someone else was down 10% to the limit-down with a full position in ST, I only dropped 5%. I haven’t made big money, but I also haven’t been hurt at the root.
In recent years, in our competition group, I’ve been copying and borrowing from here and there, and little by little I formed my own pattern, starting a more stable path back to break-even.
This post records my journey back to break-even.
