I think you’ve already answered your own question.
If the value of these shares when sold is earmarked for cash use in the near future, and your unsure about the companies future, or how stable it will be then a low risk cautious approach would be to sell and put the cash aside into a stable interest or dividend paying container until you’re planning to use it.
Its also not just about numbers, if it’s causing you stress because of your future use of it, then that may also be a reason to sell it.
One thing to note, if you do decide sell the stocks to put it aside for this ear marked use. If the share price continues to go up, this isn’t a failure. The goal of the value of the stocks is not to continue to stay in that company, but its goal is to be used for this future ear marked use. Keep this in mind.
It’s so hard to time these things
You cannot time the market. So I would say what I said before and go back to your goals. What are they, are you meeting them, to archive your goals is it time to sell or not.
If you do sell them, that doesn’t mean you cant put the money to work. if say you’re looking at using it in 6 months, you have 6 months to make safer gains from the money. That could be a stable income trust, or a simple savings account. Freetrade plus if you have is 3% interest, UK Wind if your happy with the moderate risk is roughly 4.5% dividends (bit incurs some moderate risk of stock price fluctuation), or just a savings account, Marcus is 1.5% paid monthly.
Ive mentioned a lot of selling, im not saying you should. I don’t know anything about the fundamentals of TPI, I don’t know if they’re a good company, or what their plans are for the future, or what their stock price might do. You might feel comfortable keeping yourself invested in them. You just need to balance it your your actual end goal for that money.
