From time to time, stock markets go through periods of uncertainty. During these periods of turbulence, when the markets are at their most volatile, the automatic response of many is to sell up and revert to what they think is safe โ cash.
However, it is important to remember that such periods tend to be short-lived.
Letting your emotions dictate your investment decisions during these uncertain stages can be detrimental to your returns. Pulling your investment in response to market volatility can result in significant losses over the long term, data suggests.
Analysis from 7IM found that if you had invested in the FTSE 100 20 years ago, and missed the best 30 days due to an emotional knee-jerk decision to sell during these periods of volatility, you would have actually lost money, with your annualised return coming in at -2.3%.
Putting this data into real terms, a ยฃ100,000 investment in the FTSE 100 in 2001 would now be worth just ยฃ62,895 if you had missed the best days, a loss of almost ยฃ40,000.

Ben Kumar, Senior Investment Strategist at 7IM, insisted that staying invested and waiting for the markets to settle is the โsensible moveโ.
He said: โWhen markets are choppy, people get twitchy. They start thinking that itโs better to be safe, to move to cash and therefore avoid potential pain.ย
โBut those instincts tend to be wrong. Staying invested is the sensible move and not doing so can destroy returns.โย
If you had remained invested in the FTSE 100 over the same period, your ยฃ100,000 investment would now be worth ยฃ295,372 โ almost three times more than your original figure, representing a 5.6% annualised return.
| Annualised Return | ย Total Return of ยฃ100,000 | |
| Fully Invested | 5.6% | ยฃย ย ย ย ย 295,372 |
| Missed 5 best days | 3.4% | ยฃย ย ย ย ย 193,530 |
| Missed 10 best days | 2.0% | ยฃย ย ย ย ย 147,299 |
| Missed 20 best days | -0.4% | ยฃย ย ย ย ย ย ย 93,190 |
| Missed 30 best days | -2.3% | ยฃย ย ย ย ย ย ย 62,895 |

Even missing the best 20 days would see a decline in the value of your original investment, with your annualised return down 0.4% at ยฃ93,190.
Kumar continued: โDigging into the numbers, 14 of those 20 best days were within two weeks of one of the 20 worst days. Just when youโre feeling most nervous, is when a big bounce is likely!โย
Sharp falls in stock markets tend to be concentrated in short periods of time and, similarly, the biggest gains are often clustered together.
It is not uncommon for a large surge to follow a big fall, or vice versa, suggesting that investors who attempt to anticipate when the best time to invest is, run a high risk of missing the largest gains.
