Options strategy: protect the underlying stocks
Suppose I went long on a stock and bought its shares, thinking I'd be a shareholder. ^^ BUT at the moment, the stock starts to fall, shall I hold it? Sell it? Or buy the dip and add my position?
Whoever investing in stocks has experienced that. We all dreamed of becoming rich. But the wobble has caught us by surprise.
What to do? Do nothing and let it fall?
- If I sold it, the floating loss would be realized...

With the COVID-19 pandemic last year, the stock market blown up twice. After that, a strong rebound created a huge wave of so-called stock gods. I also poured into the investment market through the wave of national stock trading. I experienced a major market correction when I didn't know what to buy. Later, when the so-called boom faded away, I discovered who was swimming naked. I also understood that the investment incident was long-term. The momentary rise and fall really didn't explain anything. Whether it's cutting meat or running out of time, these are all necessary experiences; don't overestimate your gains and losses. The important thing is to kill decisively and then be firm in your conviction.
