I vividly remember opening my Stocks and Shares ISA many years ago. While a little daunting at the time (“How on earth does the stock market work anyway?“), I’d do exactly the same thing if I were thinking of getting started with investing now. 

Why invest via a Stocks and Shares ISA?

With such an ISA, by far the biggest incentive for me is that any profits I make are free from capital gains tax. Call me miserly but I’d rather hand as little as possible back if I’ve taken on the responsibility of growing my wealth. 

The tax benefits of an ISA don’t stop there. In addition to not paying any tax of profits, I’m also not required to pay anything back for dividends I receive, assuming the investment I hold pays them.

Here’s what I’d buy

With £50 a month to invest, I’d start with buying an exchange-traded fund (or ETF).

An ETF simply tracks the return of the stock market. To give an example, the FTSE 100 index, which features the UK’s biggest companies, returned 14.3% in 2021. An ETF tracking the FTSE 100 would return almost exactly the same (once costs are factored in). 

Buying an ETF would make particular sense to me as a newbie investor because my money would be spread between lots of different companies. While this won’t stop the value of my investment from falling in tough times, there are none of the risks that come from buying shares in a single business. 

Clearly, I’m not obligated to buy a fund tracking the FTSE 100. There are actually a huge number of ETFs available following all sorts of markets and types of stock.

Nor must I stick to buying only these funds (although many people like to keep things simple and do). Once I became more confident in how the market works, I can expand my portfolio to include other assets.

Keep fees low

It’s worth saying a little more about fees. Since it’s essentially managed by a computer rather than a human (aka a passive fund), an ETF’s fees tend to be low. Over years, this really matters. It means more of my money is allowed to compound. 

I’d also take advantage of my broker’s ‘regular investing’ service. This invests my money on a set date each month rather than immediately. As a result, my commission fees (what it costs to buy or sell a fund or stock) are roughly 10% of what they normally would be. Again, these savings add up over time and allow more of what I put in to grow in value. 

Any downsides?

For me, there’s aren’t many downsides to opening a Stocks and Shares ISA. Still, let’s have a go at scraping the barrel. 

One fairly obvious cost is having less cash to spend today. There’s no way of getting around this other than to earn more and/or reduce my spend. Becoming an investor also requires patience. This is no ‘get rich quick’ scheme.

The good news is that investing for the long term quickly becomes a habit. In fact, knowing that money I put away now might/should become a great nest egg eventually makes the process rather addictive.

And of course, we’re talking about £50 here. I could potentially accumulate a lot more wealth by increasing the amount I set aside every month.
