As such, they may become increasingly reliant on emotions when making decisions. This could cloud their judgment and may mean that they miss out on undervalued UK shares that represent long-term buying opportunities.Therefore, using company data to make decisions about where to invest could be a sound move. For example, checking the balance sheets of prospective purchases before buying them will provide guidance as to their financial strength. Companies with low debt and profit that easily covers their interest payments may be better able to survive a short-term crisis. They may also be more capable of using the weaknesses of their rivals to their advantage in building a larger market share.Accessing sound business modelsA stock market crash can also expose weak business models. Previously, companies that are inefficient or that lack the capacity to adapt to changing operating conditions may have been viewed positively by investors. However, companies that have a competitive advantage may be better able to survive a period of weak economic growth.Identifying UK shares with a competitive advantage is very subjective. For example, it can mean they have a strong brand, a large number of loyal customers, or a unique product among other attributes. Buying such companies may reduce your overall risks and lead to more positive returns in the long run as they use a weak operating environment to expand their market presence.Defensive UK sharesA second stock market crash could mean that defensive UK shares become more popular among investors. In the past decade, companies operating in sectors such as tobacco and utilities have been relatively unpopular due to their modest growth rates. However, their solid financial performances in a weak economic environment may attract cautious investors. This could lead to an outperformance of the FTSE 100.Your financial prospects could be improved through buying companies that have defensive business models, sound finances and a competitive advantage at lower prices during a market downturn. They may not offer high returns in the short run, but they could prove to be the best UK shares to hold in a crisis.
