Al igual que SeeksQuality, consejo a alguien que cedió al pánico y vendió en el peor momento.
"If you’re investing in stocks, I strongly suggest that you write down what the reasons are that you would ever sell.
Do it when you are calm and thinking clearly. Make a little project out of it, spread it over a few days, when you have a thought, jot it down. Think about why you sold this time and whether, in retrospect, that was a good reason. So you can also write down reasons NOT to sell.
After maybe 5 days of jotting stuff down, clean it up into a nice, readable list of reasons to sell. Take it to heart, and hang it or store it some place where you see it all the time or have easy access to it.
Then next time, refer to the list of reasons, rather than the stock market, to decide whether to sell anything. You may find that, after thinking it through clearly, that a price drop is NOT ON your list of reasons to sell. Promise yourself not to sell in the future for a reason that’s not on your list.
A rock-solid portfolio should not tempt you to sell when it’s going through a bad patch in the market.
That will become a core part of your investing business plan. Another part, which you can work on later, is reasons to buy (or not buy). Understand how you get to a rock-solid portfolio by articulating what kind of stocks are in it.
“Rock solid" isn’t only a financial concept, it’s a psychological concept. If you own a stock that you get tempted to sell because its price drops, then it’s not"rock solid" to you. Don’t listen to everyone else, find the ones that are rock-solid to YOU.”
