r/investing on Reddit: When to take your profit from a stock.
September 22, 2024 -

Securing profits is always something I’ve questioned myself on. Picking the proper timing, and/or the proper stocks to pull gains from. Generally, I start thinking about it once I hit a ~20% gain on a stock. Selling just to secure gains is the only reason I’d sell. I’d reinvest that money into another stock or investment. Just wondering what others do, especially with those long-hold stocks.

Appreciate everyone’s feedback, and sharing some knowledge. Some really good points made. Seems like to each their own when it comes down to it. Securing the gains is my dilemma; not dissolving all my shares in the stock. Having a rule for yourself takes the guesswork out of when to sell. Obviously we cannot predict the market, but holding for the sake of holding seems counterproductive to the goal of investing. That is making money, and using that money made.

August 1, 2025 - It may help you to know what your gains and losses are so that you can gauge the winners and losers in your portfolio. Calculating stock profit also helps with tax planning and portfolio rebalancing. Calculating the dollar amount is relatively simple (you subtract the final selling price from the original purchase price, or vice versa). The formula for determining the percentage change is also straightforward:

Do you have a sell percentage (gain or loss) that you stick to, and, if so, what is it?
I don't. Because what I paid for something doesn't have anything to do with the value right now. So if a stock has a huge runup, I decide whether I'd buy it again for its current price. If the answer is a definite "no," then I sell. If a stock gets hammered by some bad news, I try to assess whether the current value is right. If something fundamental has changed and I think the stock is worth less than the current price then I sell it and take the loss. If I think the stock is worth more than the current price then I will hold onto it. More on reddit.com

How Are You Taxed on Profit from a Stock?
You would start by subtracting the cost basis from the total proceeds to calculate what you’ve earned from a sale. If the proceeds are greater than the cost basis, you’ve made a profit, also known as a capital gain. At this point, the government will take a slice of the pie — you’ll owe taxes on any capital gains you make.

How to Calculate Gain and Loss on a Stock
October 15, 2025 - You'll need the total amount of money you used to purchase your stock and the total value of your shares at the current price as well as any fees associated with your transactions. You stand to walk away with a profit of $90 if you bought 10 shares of Company X at $10 each and sold them for $20 each and incurred fees of $10: $200- $100- $10 = $90. This is just the dollar value and not the percentage change. Long-term gains or losses are realized when you sell a stock that you've held for more than a year.

However, a rapid increase in a stock price does not necessarily suggest a stock should be sold. Sometimes a major move gets underway and you might want to exploit those opportunities. Just a few of these per year can often have a significant impact on the performance of your entire portfolio. Selling too soon can be almost as detrimental to long-term returns as money-losing trades. This is why it can be important to harvest gains and then set trailing stop losses.

July 1, 2024 - Selling an investment at a loss may be easier to accept when you know the loss can be used to offset capital gains and may reduce your tax bill. “But don’t sell an investment solely for tax reasons,” McGregor says. Even if the investment has hit a rough patch, consider its prospects and the role it plays in your portfolio. It may be a good idea to talk with both a tax professional and your financial advisor before selling. The share price of a stock shouldn’t be viewed in isolation when considering whether to sell.

If you sell 50 shares, typically, the first year's shares at $10 per share would be sold. If you hold onto those shares, you can select which shares to sell when you do so. In other words, you can choose the shares you paid the most for ($20), which can lessen the amount of capital gain and, as a result, the amount of taxes paid.

You sell stock by placing an order with your broker. You fill out an order form that will ask what stock you want to sell, if you want to sell in shares or dollars, how much you want to sell, and if you want to sell via a market or limit order. Ideally, you'll be selling the stock after it has grown in value from when you bought it, locking in a profit.

When to Sell Stocks: 5 Reasons to Sell a Stock | The Motley Fool
May 14, 2025 - Another potentially good reason to sell is if a company announces it has agreed to be acquired. After an acquisition is announced, the stock price of the company being acquired typically rises to a level close to the agreed-upon purchase price. Since further upside potential can be quite limited, it may be wise to lock in your gains shortly after the acquisition announcement.

Common fallacy ...

Every new trader "invents" this idea.

You'll simply get closed out as stocks move down.

So,

I [buy a stock] and each time the stock goes up (even if only 1 moves each month) 2% I sell that stock ...

It's completely commonplace that you buy a stock, and from that day forward it goes only down, whatsoever.

In your example just one of your $500 bets could turn in to, say, $120 or $150, making you lose 300 or 400 bucks.

Or you could "merely" lose $200.

That enormous loss on just one of your "plans", would completely wipe out the pathetic gains of a few dollars you are making from all your other "plans".

I hope it makes sense.

One loss utterly wipes out literally hundreds of other "wins":

To try to explain it another way:

you are simply wildly underestimating how often and much you lose when you try this.

You'll find this question will probably just get closed because every single new trader "invents" this idea. Every. Single. Time.

In the history of the universe, Every Single Person who has thought about "trading! stocks!" has "invented" this idea.

You now know clearly why it doesn't work: you are simply wildly underestimating how often and much you lose when you try this.

These days you can very easily "paper trade" stocks. I urge you to try it.

I will give you 10 thousand real bucks if you can show it worked.

Enjoy paper trading!


BTW there's a similar "everyone invents this..." with gambling. Every new gambler, say roulette player, invents the Martingale "method". (You can google it up.) It too (obviously, or everyone on Earth would be a billionaire) has a Fatal Flaw.


Unrelated question. Stock picking:

Regarding unrelated "Scenario 1" also mentioned in the question...

That's just called "stock picking". (You better be good at picking the 20.)

The more you have in the basket, the safer it is. The less you have in the basket, the more risky it is in both directions. In fact ........... the very best way to invest is nothing more than:

That's the whole story.

There's nothing else to "investing".

If you think you can pick a basket of "20" stocks, where you believe Your Basket will do better than an ordinary S&P index fund: that's just called "stock picking".

You will not be able to do better than an ordinary S&P index fund.

10,000s of stock pickers try this every year ........... and they all spectacularly fail.

How to lose 50 billion in a few months:

Here's a joker who lost fifty billion dollars by picking a basket of 20 or so stocks - literally exactly as in the question.

(Hilariously: afterwards, the guy in question, the only thing he had to say for himself was: "Yeah. It's hard to beat the S&P." OK, no shit Sherlock. Nice call. Good way to lose 50 billion of other people's money.)

Some "beat the S&P" 1 year out of 10 or 20, which is just random.

Making 1% a day is quite possible for a few days or even a few weeks if you're on a have a hot streak, and you're trading a small amount of money. But doing that consistently is impossible. No one makes 250% a year (trading a fixed amount) or 1,100% if you're compounding the 1% gains as well).

Here's a simple example to demonstrate the problem with your strategy. Suppose you invest $500 in 3 stocks.

  • Stock A makes 50% and that's + $250
  • Stock B makes 24% and that's + $120
  • Stock C loses 50% and that's - $250

Your total gain is $120 so your yield is 8% ($120/$1500). Success! Your strategy works!!!

But wait, you said that you were going to sell your stocks when they rose 2%. Oops, because of that, you didn't make $250 on Stock A and you didn't make $120 on stock B. In fact, you only made $10 on each so you have a net loss of $230 or -15.33%.

The fallacy in your strategy is your assumption that you "pick 10 good stocks and 10 bad ... (and) the stocks made and lost the same value." Sorry, but it doesn't happen that way. Stocks will have varying amounts of gain and loss.

One of the most important tenets for a trader is “Cut Your Losses and Let Your Profits Run”. You've reversed that by cutting your profits and assuming that your losses won't be more than a small amount. Some will lose more than a modest amount.

Successful stock trading requires that you have an edge (a strategy that works) as well as disciplined risk management. Your strategy has neither.

As an aside, in March, the stock market dropped about 35%. How do you think that your strategy would have worked then?
