“Diamond Hands”
Don't do it
Right, let’s talk about another bit of investing folklore that’s doing the rounds: “diamond hands.” You know, that heroic-sounding phrase that gets trotted out every time someone’s holding onto a losing position like a drowning man clutching a brick.
It’s become the battle cry of the Trading 212 Community whenever someone’s investment goes tits up. “Just diamond hands it, mate!” they cry, as if sheer bloody-mindedness is somehow a substitute for actual investment strategy. But here’s the uncomfortable truth - most of the time, “diamond hands” is just bag-holding with a catchier name.
And frankly, the difference between diamond hands and being a stubborn mug is usually about 50% and six months of denial.
The Mythology of the Unbreakable Grip
The whole diamond hands narrative sounds brilliant on paper, doesn’t it? You’re the steadfast hero, refusing to bow to market panic while weaker investors flee like scared sheep. You’ve got conviction, determination, the sort of steely resolve that legends are made of. You’re Warren Buffett during the 2008 crisis, calmly holding while others were selling.
Except you’re not Warren Buffett. You’re probably someone who bought Mullen Automotive and is now down 99% but trying to convince yourself that holding it is a display of superior investing wisdom rather than an expensive lesson in speculative investing gone horribly wrong.
The problem with the diamond hands mythology is that it treats all holding as equal. But there’s a massive difference between holding a fundamentally sound company through temporary market turmoil and clutching onto a speculative punt that’s slowly bleeding out. One is intelligent patience, the other is just expensive stubbornness.
When Diamond Hands Becomes Bag Holding
Here’s what actually happens in most “diamond hands” situations. Someone buys a stock based on hype, social media buzz, or because their mate Dave said it was “going to the moon.” The price promptly tanks, as speculative investments tend to do. Rather than admitting they made a mistake, they decide they’re going to show the market who’s boss by refusing to sell.
This isn’t conviction - it’s loss aversion dressed up as strategy. Your brain is playing tricks on you, making the pain of realising a loss feel worse than the ongoing pain of watching your money slowly evaporate. So you hold, telling yourself you’re being patient and strategic, while your investment continues its leisurely journey toward zero.
The cruel irony is that genuine diamond hands - the kind that actually pay off - usually don’t require constant self-motivation. If you’re having to convince yourself daily that you’ve got diamond hands, you probably don’t. You’re just someone who’s confused being stubborn with being smart.
The Sunk Cost Fallacy in Action
Diamond hands culture is basically the sunk cost fallacy with a superhero costume on. You’ve already lost money, so your brain tricks you into thinking that selling now would somehow make that loss “more real.” But here’s the thing - the loss is already real whether you sell or not. The only question is whether you’re going to compound it by throwing good money after bad.
As legendary trader Jesse Livermore put it: “The most important rule of trading is to play great defense, not great offense.” - he was a Yank, so I’ll spell it his way (incorrectly). Sometimes the most diamond-handed thing you can do is cut your losses and live to fight another day. But that’s not nearly as romantic as the mythology suggests.
The really insidious part is that social media has turned bad investing decisions into a team sport. People are now peer-pressured into holding losing positions because selling makes you a “paper hands” weakling. It’s financial Stockholm syndrome with emojis 💎✋.
What Real Conviction Actually Looks Like
Genuine investment conviction isn’t about refusing to sell no matter what happens. It’s about understanding what you own and why you own it. If your entire thesis for holding a stock is “diamond hands,” then you don’t have a thesis - you have a slogan.
Real conviction means you can articulate why you believe in a company’s long-term prospects, understand the risks involved, and have a clear idea of what would make you change your mind. It means doing proper research before you buy, not just hoping that stubbornness will somehow transform a bad decision into a good one. You should be able to illustrate the business model to a 5 year old in crayon.
Warren Buffett - the patron saint of long-term investing - doesn’t hold stocks because he’s got diamond hands. He holds them because he understands the businesses, believes in their competitive advantages, and thinks they’re trading below their intrinsic value. When those factors change, he sells. That’s not paper hands - that’s intelligent capital allocation.
The Opportunity Cost Nobody Talks About
While you’re busy diamond-handing your way to financial martyrdom, something else is happening that nobody wants to discuss: opportunity cost. Every pound tied up in your slowly sinking investment is a pound that could be working harder elsewhere.
The market doesn’t care about your emotional attachment to a losing position. It doesn’t reward stubbornness or respect your determination to “show them who’s boss.” While you’re holding onto yesterday’s mistake, you’re missing today’s opportunities.
As the saying goes, “Your first loss is your best loss.” Sometimes the most profitable thing you can do is admit you were wrong, take the hit, and redeploy your capital somewhere more promising. But that requires swallowing your pride, which apparently is harder than swallowing your losses. Please don’t swallow the crayons though…
When Holding Actually Makes Sense
Don’t get me wrong - there are absolutely times when holding through volatility makes perfect sense. If you own quality companies with strong fundamentals, reasonable valuations, and clear competitive advantages, then short-term price movements are just noise. The key word there is “quality.”
But if your holding strategy is based on hope rather than analysis, if you can’t explain why the investment will recover beyond “it has to eventually,” then you’re not displaying diamond hands - you’re displaying denial. And the market has a nasty habit of keeping you in denial longer than you can afford to be wrong.
The Bottom Line
True investing wisdom isn’t about having the strongest grip - it’s about knowing when to hold and when to fold. Sometimes the most diamond-handed thing you can do is admit you made a mistake and move on.
So the next time someone on the Trading 212 Community starts banging on about diamond hands, ask them this: are they holding because they’ve done their homework and believe in the long-term prospects, or are they holding because their ego can’t handle admitting they were wrong?
Because one of those approaches builds wealth, and the other just builds character. And frankly, character is expensive enough without paying market prices for it.

Lots of common sense, no doubt, but one thing I rarely see from investment commentators is just what "do your own research" entails. Sure, one can analyse the latest set of accounts, one can listen in to the latest CEO & CFO commentary (always spouting on why the future is looking great!), possibly one can do a mystery shop if the investment operates on the high street, but what else can one do? Broker notes? Expensive, or if free then paid for by the investee company. Chartism? Many bowls double dip on their way to extinction! After all, investment is about hopefully future returns. Some article about how you go about "doing your own research" might be a useful topic for the future.
