A stock market crash may be coming! 3 tips for ISA holders

Stock market crashes, corrections, and general periods of volatility are part and parcel of investing. They needn’t be feared but we do need strategies to deal with them.

With its attractive tax advantages, I reckon a Stocks and Shares ISA is the best investment vehicle available on the market today. That doesnât mean itâs immune from the effects of a financial meltdown, but with some sensible precautions, we can one to reduce the potential damage from turbulent times. Here are three tips.

When I last wrote about a market crash, I thought it would come from a loss of confidence in the tech sector rather than war in the Middle East. Technically speaking, we havenât experienced a crash yet â typically defined as a fall of 20% from a recent peak — but if the conflict persists for much longer, this could become a real possibility.

1. Be ready

For all concerned, Iâm hoping the war will end soon. And when it does, there will be many beaten-down stocks available with attractive valuations.

One of those suffering at the moment is Wizz Air (LSE:WIZZ). The budget airlineâs share price is now (9 March) 40% lower than at the start of the month. And itâs fallen two-thirds since March 2022. Higher fuel costs following Russia’s invasion of Ukraine and, more significantly, aircraft being grounded because of engine problems have hit earnings.

And if flight cancellations persist and the oil prices continue to rise, the group estimates that the current trouble in the Middle East could cost up to â¬50m.

This is unfortunate given that the groupâs trading update for the quarter ended 31 December 2025 disclosed that revenue was up 10% and passenger numbers grew 12.5% compared to a year earlier. Net losses fell from â¬241m to â¬139m. Encouragingly, the engine issue is being gradually resolved with fewer aircraft grounded. All are expected to be repaired by the end of 2027.

However, Iâm not suggesting that the airlineâs stock is one to consider now. Thereâs too much uncertainty around at the moment, which makes me think its share price has further to fall. But I think it will be worth revisiting the investment case when the conflict is over. Thatâs what Iâm going to do, anyway. Then, with fuel costs easing, our skies fully open, and more engines returning into service, growth could resume once more.

2. Keep spreading risk

Irrespective of what happens to Wizz Air, I think itâs important to maintain a diversified portfolio. During market downturns, some stocks do better than others. For example, with their reliable earnings, utilities tend to cope better. Holding positions in a wide variety of companies and sectors is always a good idea.

3. Don’t panic

Most importantly of all, I think itâs vital to take a long-term view. Even if the war ends soon as we all hope, a future stock market crash is inevitable.

Thatâs not me being negative. Itâs simply a statement of fact based on history. But another lesson from the past is that markets do pick up again. It might take a while but things will â more than likely â get better.

By taking a pragmatic approach, I think itâs possible to guard against the worst of the current fallout and any future crashes. And by identifying a few bargains, I believe it’s possible to benefit massively from a recovery.
