Buying low and selling high? Maybe you’re doing it wrong…

For decades there has been a prevailing belief to “buy low and sell high” in order to be profitable when investing. It’s time to retire that expression.

Legendary investor, Howard Marks, has publicly stated his opinion that selling an asset (even when you have made a profit) may be foolish. His justification for this statement is that, although taking profits never made anyone broke, selling an investment interrupts compound interest and can cause you to lose out on excess returns. Let’s explore why this sentiment holds true and how it can benefit you in the long term.

Compound interest: Is it really that powerful?

Now, you may have heard the saying that compound interest is the 8th wonder of the world, and there is good reason for that premise. Compound interest plays on momentum and is responsible for nearly all investment success. If you have ever watched your favourite team score that winning goal in the last ten minutes after being down the whole match, then you know that momentum has a funny way of driving a team to success — the same goes for investments.

Let’s explain this through a simple example:
You are given two options. Every day for a period of time you can either receive a dollar or you can receive a single cent that will double in value, which would you choose? You might be inclined to choose the dollar option, it is worth 100x more in value than a cent after all. It seems like the logical choice. But consider that on the 12th day, the person who chooses the dollar will have $12 and the person who chooses the cent will have $20.48.

That’s the magic of compound interest.

Now that you know how powerful compound interest is, you can see why interrupting compounding is not ideal.

Does this mean you should never sell an investment?

Marks says there are two situations where you should sell: either there is a better investment opportunity or when the reason you invested in something is no longer true.

For example, if you’ve invested in a stock that was making a lot of revenue but has now stopped returning that money or if the company is facing legal trouble that could sink the business, then you should think about selling. The same goes for if you discover a much better investment, which is known as opportunity cost or the cost of missing out on an opportunity. Other than these two main reasons, Marks believes that selling for any other reason does more harm than good.

But trading an asset can’t be that harmful to investment gains, can it?

Yes, it can. A study was done on the S&P 500 (an index of the top 500 US stocks) and its return profile from 1996 to 2015.

It was found that, on average, the S&P 500 returned +8.2% year-on-year for 19 years straight. To put that into perspective, if you invested $1,000 in 1996, it would be worth $4,469 in 2015 or a +347% return.

The study then further looked at the effects of missing out on top trading days in the market due to people trying to trade and not simply invest and hold.

What they found was staggering.

From the above graph, you can see that if you missed out on the top 10 trading days because you were trying to time the market, your returns shrank to just +4.5% per year. That means you earned less than half the returns on your $1,000 investment (making a total of $2,307). Missing out on the top 20 trading days means your returns came in at just +2.1% per year, that’s a loss of $2,987 extra. Finally, missing on the top 40 days, you actually lost -2% per year for 19 years — causing you to have $681 at the end of the period instead of $4,469 from just holding.

This study demonstrates the power of long-term investing over-trading.

So the question becomes: Do you think it’s worth taking the risk of trying to trade the markets if it means losing out on most of your investment’s potential return?

What does this mean for me?

The cryptocurrency market is like every other financial market. The main difference is that the historic returns are higher over most comparable time periods and the price swings, otherwise known as volatility or risk, are greater but that makes it even harder to try to trade and time the best buying and selling points.

But if you take a long-term view and look at the bigger picture, the crypto market shows a clear trend and the returns have been well worth the extra risk.

As seen above, the crypto market, represented here by Bitcoin, follows a clear trend. If you try and trade it day-to-day this can become a costly mistake and you could miss out on earning some incredible returns that compound over time.

How do I know what to invest in for the long term?

Nobody knows with 100% certainty which investment will be the best over the long-term, but you can use a smart trick that almost all investors use: diversification. The old adage of not putting all your eggs in the same basket.

Diversification accomplishes two things:

  1. It reduces your risk and makes your overall investment journey a less volatile ride, and
  2. It spreads your bets across multiple potential winners and can be considered a clever way to invest in an emerging innovative space, like cryptocurrencies, where the winner could be anyone.

As an investment analyst at Revix Chris Beamish loves to say, “Investing in crypto is like investing in the internet in the ‘90s.”

Early-stage innovative technology has been a great investment opportunity as the world has clearly seen with the rise of the internet.

Chris continues, “Out of the top 50 internet stocks at the very peak of the DotCom bubble in

2000, 88% of those stocks didn’t make it and went bust by 2017. But the winners in that top 50 ended up being Amazon, Google, eBay and Yahoo. The small allocation made to these winners made up for the losses of the losers and ended up returning around 14% per year during that period.”

Crypto Bundles or diversified baskets of cryptocurrencies that either track the overall crypto market or certain sectors within the crypto space are the easiest and smartest way to gain exposure and invest in the crypto market. It’s similar to investing in an ETF, where you get loads of low-cost diversification through a single investment product.

When it comes to Crypto Bundles, there really isn’t a more trusted name in town other than Revix. Not only will you constantly hold the largest and most reputable cryptocurrencies but your Bundle will also automatically rebalance every month to keep you up to date with any possible new winners entering the space. This way you never miss out on holding what could potentially be the next Amazon.
