Diversification - how many stocks is too many?

Makes sense. I should say about 10 of mine are ETFs so not all individual companies. But it is hard to keep track

ETF’s are a solid option. I’m actually going to lower my number and say 25 because my I’m at the upper limit right now with 22.

I like @hrochfor1 point:

I’ve committed my 4/5 hours a week to gaining wealth but there is an awful lot to be said for preserving wealth given the impacts of inflation. My prediction for higher inflation in the next few years will make preservation even more important.


I’m starting out by having the majority of my holdings in index funds complimented around 20-30 companies. Then once I’m more competent with stock picking I’ll then probably focus on individual companies.

I guess it comes down to whether you feel like you’re confident enough to be able to beat the market. Studies do show that individual investors aren’t very good at stock picking and should stick to index funds or ETFs.

Just my opinion but I pay more attention to the sectors I’m spread over and if I feel I have a good mix in each sector. And I pay attention to the £ amounts I have allocated to each within the sector eg larger amounts for solid established firms and tiny amounts for wild cards etc.


I do not currently hold many, I am very liquid at the moment, but I do have a plan of investing in around 70 companies and 6 ETFs once the market dips again.

My idea is to have about 25% of it invested in around 50 companies, creating my own “ETF equivalent” so to say (average of around 0.5% each) within an ISA.

The biggest chunk, 65%, I intend to invest it in around 20 companies, which equates to around 3.25% of my portfolio each (ranging between 5% and 2%).

The final 10% will go to 6 ETFs, which I intend to grow/add to with time. The proportion of ETFs will growth with time.

This is a topic that @adam and @Viktor touched on during the AMA on Tuesday. I was relieved to hear @adam would like to see more ETFs available on Freetrade. Personally, one of the things keeping me from a balanced and diverse portfolio is the lack of ETFs. Particularly for the European and Asian markets. I’m hoping @Viktor can add some more ETFs with the next batch of UK stocks!

I put in two ETF requests yesterday if anyone would care to vote :grinning: :+1:

Currently my portfolio has a mixture of US/UK stocks (approx.14) and ETFs (S&P500, FTSE, Japan)


I missed the AMA but good to know it’s being discussed

30 stocks is a widely accepted rule of thumb, but here is a good article digging into it a bit more: https://www.investopedia.com/articles/stocks/11/illusion-of-diversification.asp


Thanks @adam

The consensus from the vote seems to be 40 is too many. Need to control my urge to buy - unfortunately you have made it so easy I’m like a kid in a sweet shop :slight_smile:

I’ve made a deal with myself, that I won’t buy any more companies without liquidating an existing one - 40 will be my ceiling.

32 in my ISA
8 in basic account

ISA Split
37% Tech
19.5% Other (ETF’s)
13.2% Cars
11.6% Energy
5.6% Finance
5.3% Entertainment
4.6% Property
Then the lower percentages on Mining, Food & Drink, Travel.

Hopefully that is considered a fairly reasonable spread! Any opinions welcome :+1:

Not dissimilar to mine in terms of sectors. I’m slightly less tech heavy and more property though, and cars is only as high in mine due to Tesla going mad :wink:

William O’Neil is one of the most successful investors ever and his books have been read by millions. He has a bit of a cult following in America with IBD.
His portfolio size rules are one of the most important aspects if you want to be able to achieve big returns.
In a selloff everything tanks. With fewer holdings it’s far easier to be out of the market then if you have 20+ stocks.
Obviously this approach is only if you want to be an active investor who picks their own stocks and are confident in your ability to pick the best opportunities.
Everyone else should just be investing in funds or trackers.

Another big believer in concentration is Warren Buffett. Charlie Munger even more so. In fact any investor who consistently outperforms will be running a concentrated portfolio.


If you’re making money stick with what you’re doing.
Remember to take profits in these volatile markets.

Like a few have said if you bought every share available on Freetrade - you would be better off just buying a few ETF’s

That’s fair enough, but what’s the magic behind the 40 number? As I’m sure you don’t need me to tell you, diversification isn’t a out how many stocks you own, it’s about how similar your stocks are to one another. I used to be at around 50 with about six different US banks. I’m now down at 27 but axeing 4 banks to being me down to two hasn’t done any great violence to my diversity profile.

I think I’m fairly well diversified - but maybe I’m just delusional?

I feel like ‘well-diversified’ is all relative. Obviously you’re spread over a decent range of industries. But without seeing your holdings, it’s possible that someone could be more ‘diversified’ than you with two ETFs. Main thing is that you’re happy with your portfolio as a representation of your view of how things are going to go over the time frame that you’re planning on investing in. Good luck with it :slight_smile:


From @adam’s post:

i got 25 that i have dabbled in but i think in the long term i am going to aim for about 12 well established companies in 8-10 different sectors.

But all depends what your after, if you trying to day trade or long term. I am thinking of 4 or 5 for long term / divi payers. But then with the current market so volatile its easier to make some gains better than the up coming divi
