On investing £1000 a day in the S&P 500 for 30 days, the results, and why I will never do it again.
I see a lot of these challenges where people are investing £1, £5, or £10 into the stock market or gold.
People seem to love them for two reasons:
- It’s an accessible goal. £1 a day is £30 at the end of an average month, so it’s not absurd to be saving that much, but it feels like something.
- Increasing the “pot” daily feels like you are building to something, and you don’t have to wait until the next month for the next deposit. In other words, it’s something interesting each day.
As a content creator, I took it way further and decided to go for “investing £1000 a day”. As the ancient Buddhist saying goes, “go big or go home.”
In this article, I will explain what happened and also why I will never do it again.
Why did I do the investing £1000 a day Challenge?
I got invited to join TikTok by a rep, supposedly, they wanted people who have over 10k YouTube subscribers or 100k Instagram followers to join TikTok and do some kind of daily posting challenge.
And they pay some money to you for doing this challenge as some kind of signing-up bonus, but there are a load of terms and conditions, ifs and buts, and loopholes.
I don’t think TikTok or shortform fits The Dividend Experiment content.
I think there is a lot of nuance on investing topics, and that can’t really be learnt or explained in the short time you get on a TikTok.
So I started this investing £1000 a day challenge on a new TikTok channel, thinking about posting it every day.
To make it more interesting, I introduced another part of the concept where viewers can post the tickers of stocks and vote for the ones they want to buy and add them to a special pie just for the series to do some comparison.
It was a good idea, but TikTok thought I was scamming, so it restricted the views, and it never really took off.
Investing £1000 a day: How the S&P 500 Performed During the Challenge
The S&P 500 has not been doing that well so far this year.
As of now, it’s down 6.39% year-to-date.
So, naturally, the £30,000 invested over 30 days was also down.
Not sure what you were expecting, really.
The result of investing £1000 every day the market was open was a –7.77% return.
If I had invested all the £30,000 at the beginning of the series instead of daily, then the portfolio would be down 9.67% instead of 7.77%.
So, if it reduces the % of losses, why will I never do it again?
The reason can be reduced to: it went well in this case, because the market was trending downwards, but it would have been the opposite if the market had been trending upward.
And the market has historically trended upward over the long term.
Investing £1000 a day: Why Lump Sum Investing (Usually) Outperforms DCA
The logic behind lump-sum investing is rooted in one of the most consistent patterns in financial markets: they tend to go up over time.
When you invest a lump sum, say £30,000, all at once, you’re giving your entire portfolio immediate exposure to the market.
That means every penny starts compounding right away, taking full advantage of any upward movement in prices.
And when you’re investing for the long term, that head start matters.
The Market’s Long-Term Direction
Historically, stock markets have gone up about 70–75% of the time when you look at annual returns.
The S&P 500, the most tracked U.S. index, has delivered an average annual return of around 10% (before inflation) since 1926.
The FTSE All-Share in the UK has similarly returned around 7–8% per year over the long term.
Even when you factor in bear markets, corrections, and crashes, the trend is still upward because companies grow, economies expand, and innovation drives long-term value.
So, if you’re sitting on cash, waiting for a “better time” to invest, you’re likely missing out on positive returns.
Vanguard Study
One of the most cited studies on this topic comes from Vanguard.
They compared lump sum investing (LS) with cost averaging (CA) across various time periods and countries.
Here’s what they found:
- In the U.S. market, lump sum investing outperformed DCA in about 68% of scenarios over a 10-year rolling window.
- In the UK, lump sum beats DCA in about 67% of cases.
- In Australia, the number was 66%.
They tested this by taking hypothetical investors who either invested all their money at once or spread it out evenly over 12 months, then compared the performance after the full period.
The takeaway? Two out of three times, lump sum wins.
And in one-third of cases where Cost Averaging performed better, it was usually by a smaller margin than the lump sum’s advantage in its winning scenarios.
Investing £1000 a day: The Power of Time in the Market
Compounding is the key reason why lump-sum investing tends to outperform. The earlier your money is invested, the longer it has to grow.
Let’s say you invest £10,000 today vs. spreading it out over 12 months.
Even if the market drops slightly after you invest, if you plan to hold for 10–20 years, that initial dip barely matters.
But every month you delay investing part of that £10,000 is a month it’s not growing.
The Fear of a Market Crash After Investing
That’s the fear that keeps people from lump summing. What if you invest £30,000 today and the market tanks tomorrow?
It is a fair question, and there are rare cases where DCA performs better in the short term, especially during extreme downturns.
Take 2008: investing a lump sum in October 2008 would’ve meant watching your money drop by another 20%+ in a matter of weeks. In that kind of environment, DCA would’ve felt safer and potentially performed better.
But here’s the key: those situations where cost averaging works better are exceptions, not the rule.
Most people can’t predict crashes.
Most people aren’t investing for 3 months; they’re investing for decades.
Even if you invest right before a crash, markets usually recover within a few years.
Case in point: if you lump-summed in October 2007 (just before the 2008 market crash), your portfolio would’ve been underwater for a while. But by 2012, you’d be back in profit, and by 2020, you’d be well ahead.
In the long game, time smooths out bad timing.
Why Are There so Many £ 10-a-Day Challenges on Social Media?
If you spend any time on TikTok, Instagram Reels, or even the Trading 212 pies, you’ve probably seen them: the “£10-a-day investing challenge” videos.
Someone decides to invest a small amount daily for 30 days and posts their progress, complete with colourful charts, emotional ups and downs, and a final reveal at the end: “I made £14.73” or “I lost 3.5%, here’s what I learned.”
But while these videos are everywhere, they’re rarely about smart investing; they’re about engaging content.
Here’s why these challenges have taken over financial social media, and why they persist despite being ineffective as actual investment strategies.
1. They’re Easy to Understand (and Easy to Copy)
Most people are not finance nerds.
They’re regular people who want to feel like they’re doing something good with their money.
And that’s what makes the “£10-a-day” challenge so effective: it’s simple, tangible, and repeatable.
You don’t need to understand index funds, ETFs, diversification, or compound interest to follow the story.
You just need to know: £10, every day, into something that grows.
That simplicity is key.
Complex financial concepts don’t spread easily on social media.
But this? Anyone with a spare tenner and a phone can replicate it.
It lowers the barrier to entry, not just for investing, but for making content about investing.
It’s also a great hook. “I invested £10/day for 30 days” sounds like a clear narrative.
It invites viewers in; you know what you are expecting going in, and are curious to see how that ends.
2. They’re Great for Engagement (and Algorithms Love It)
These challenges have a natural episodic structure: Day 1 to Day 30.
That gives creators a built-in content calendar, and audiences a reason to keep watching.
If you do it daily on TikTok, Shorts, or Instagram, then there is no need to think of new ideas every day, and editing is way easier.
At the end, you can make a whole video that gives the audience a kind of debrief after the month.
It taps into the same appeal as fitness transformation vlogs, “No Spend” months, or 30-day productivity sprints: there’s a clear beginning, a middle, and an end.
From a content creator’s perspective, this is gold:
- Frequent updates drive views and comments.
- Viewer curiosity builds over time: “How much will they make? What’s the total at the end?”
- Engagement spikes as people offer advice, feedback, or argue over which stock or ETF they should’ve chosen instead.
Social media algorithms reward this behaviour.
The platforms push content that people interact with, and investing challenges are built for interaction. They’re not just personal finance.
They’re storytelling, and the market just happens to be the backdrop.
3. The Challenges Feel Empowering (Even If the Actual Impact Is Minimal)
For a lot of people, investing feels intimidating.
Headlines scream about crashes, volatility, and inflation.
The idea of dropping £5,000 into the market all at once feels pretty reckless if you’re not used to it. But £10?
That feels manageable; that’s probably how much a pint of beer costs in London now.
These challenges give people a sense of control.
Even though the actual financial impact is relatively small, 30 days of £10 would be £300 over the course of a month, it feels big because it represents a shift in mindset: “I’m not just spending money anymore. I’m building towards something.”
Therefore, in my opinion, it’s more about behaviour than the portfolio size or returns.
These videos and challenges aren’t really about maximising gains; they’re about proving to yourself (and your followers) that you can commit to a plan.
They deliver instant psychological wins:
- Discipline
- Consistency
- Visible routine
It’s investing as habit-formation, which is great. But, importantly, it’s not the same thing as an effective portfolio strategy.
4. It’s More of a Starting Point and Less of a Strategy
This is where the disconnect happens.
A lot of creators and viewers treat these daily challenges as if they represent an investing method, something to be optimised, analysed, or followed religiously. But they’re not.
They’re on-ramp content.
They serve as a first step for people who’ve never invested before. And in that sense, they do have value.
- They demystify the process
- They get people to open a brokerage account
- They reduce the fear of getting started
But long-term investing isn’t about what happens over 30 days with £300.
It’s about what happens over 30 years with as much capital as you can realistically put to work.
Challenges like these are great for building confidence, but they can also give a false impression of what real investing looks like: boring, diversified, automated as much as possible, and mostly hands-off.
If someone walks away from one of these challenges thinking they’ve “tested” investing and now know what works, that’s misleading.
It’s like doing a 10 push-up-a-day fitness challenge for a month and assuming you’re ready for the Olympics and wondering where your six-pack abs have gone.
5. Low Fees Make It Possible
One big reason why these kinds of daily investing challenges are even possible, especially the “£1 a day” or “£10 a day” style, is that platforms like Trading 212 exist.
There are other low-cost platforms; in fact, there is a whole spreadsheet of them with pros and cons in the Dividend Temple discord.
I will use Trading 212 as the example here, as it’s what I used for the challenge.
Back in the day, if you tried to do something like this with traditional brokers, you’d get absolutely rinsed by fees.
I’m talking £5 to £10 per trade, minimum, which would destroy any return you’d make on a small daily investment.
Imagine putting in £10 and losing half of it just to place the order. No thanks.
But with zero-commission trading, a low 0.15% FX fees on fractional shares, and the ability to build custom Pies, Trading 212 makes it actually viable to invest small amounts daily without the platform eating your returns alive.
It’s not just about low fees either; it’s the accessibility.
Fractional shares mean you don’t need to wait until you’ve saved up £300 to buy one share of something like Microsoft or Amazon.
You can just toss in a few quid and still get exposure.
That’s a big part of the reason these challenges have taken off.
It’s not just people copying each other for content; the infrastructure now exists to make this kind of micro-investing frictionless.
If you tried to do this challenge ten years ago, you’d either be laughed out of your broker’s office or you’d go broke on fees before day 10.
Final Thoughts: Investing £1000 a day challenge
So that’s the result of investing £1000 a day challenge.
If you’re sitting on a large sum of money, trying to decide whether to invest it all at once or drip-feed it in slowly?
The data is pretty clear: lump sum investing almost always wins over the long term because time in the market is what really matters.
If you see something popular on social media, then it’s probably just because it’s popular on social media, not that it is genius advice that should shape how you invest.
Of course, this is a pretty benign example of social media influencing investing, but important to remember that good content for views and good investing don’t necessarily align.
My thoughts on when/how often you should invest
Well, I’ve been pretty pro-Lump Sum for a while, so my general thoughts on it are to:
- Make a budget plan for when you get paid, include some % of your income as an investing allocation along with bills, rent, etc.
- Invest it pretty much as soon as you get paid, like it’s a bill due on that day.
- No funny business about holding it for the next week or splitting it up into daily increments
- If you get paid monthly, invest monthly. If you get paid weekly, invest weekly.
- Anything else is probably overthinking it.
