I asked the question because I did the opposite of your approach. I went from being a long term investor to a trader or speculator.
I took early retirement in 2000 and watched my nest-egg get decimated in the years that followed. Granted the market did recover and I held through the downturn but I wasn't something that I wanted to repeat. I changed my priority to one of capital preservation.
I still want to be in the market to achieve the returns I'm looking for, but I don't have to hold thru the ups and downs.
My strategy has changed from fundamental where the data suggest what a stock should do, to technical where the data tells me what the stock is doing. The strategy has kept me out of the 2008, 2020 and this most recent downturn.
I at one time owned a stock I would think is similar in nature to TSLA. A growing tech company with a great product, first to the market, a darling of the business world. Research in Motion. The blackberry was the leading cell phone used by business.
Two things brought about it's downfall. A new product that no one took seriously (the i-Phone) and management got distracted.
Now right now there is no new product that I'm aware of that might unseat TSLA but you can be sure everyone is working on one. As far as management being distracted, that's a given.
I got out of Research in Motion during the 2008 downturn. Strictly technical reasons. But it's an example of a company that had a great following that didn't live up to the hype.
I now ask myself what is the downside to holding a stock that is in a down trend. If the answer is it could continue to go down and stay down, then there is no reason to hold it.
You have to remember that my trading life started in 2020, at a time you call a downturn but to most was a lifetime bull market. Very unique circumstances led me to anticipate the crash and, just as important, to jump back all in TSLA at the end of March, at the bottom, that I traded furiously until Q1 '21 when I realized that the market was behaving differently from what I only knew, and paused to ponder.
I think there ought to be a risk reward for trading instead of investing. I know that trading TSLA through 2020 led to higher returns than if I had simply invested. I asked myself if the associated stress was worth it but dismissed it as a woulda coulda shoulda question. Hindsight is 100% and I don't know what my stress would have been passively checking in on TSLA performance.
Anyway, 2021 was a year of learning real basics as in, what is trading and how does it fit with my personality, my lifestyle, my capabilities and which type suits me best. I've been learning, experimenting, making mistakes, trying again, making more mistakes, etc. and giving back some of my previous year's gains. I cashed out at the right time, then mistimed my re-entry earlier this year and took the dive like so many until I sold all my losers, and regrouped behind TSLA, because I'm convinced it's a 600+ stock that will weather the storm better than most.
I think it's important for other newbies like me to consider a decision over a time span, rather than an immediate consequence. I'll use an example for clarity. I had been trading MSTR for about 18 months, had gotten familiar with its trading pattern, its volatility, and was doing relatively well until BTC crashed. I was left hanging high but believed BTC would rally. Months later I finally took the loss and bought back low, ready for the rebound. Instead, the price dropped again so I finally gave up and sold. And I've been holding this negative feeling for the last several weeks for losing my edge on a stock I had been successful with for many months.... until last night seeing MSTR down over 20%. And all that ridiculous pent-up frustration instantly turned into relief. It's a reminder to keep emotions out of trading decisions.
