The investing genius has a reputation for piling cash into the stock market when others are running scared. His reasoning is simple, it enables him to buy shares in quality businesses while they’re cheap. As a result of his long-term strategy and calm temperament regardless of the prevailing market conditions, Buffett has made billions.As such, I’d still buy cheap shares in quality companies today.

This can be a fatal mistake, especially if the company’s share price has much further to fall. To eliminate the chances of this happening, it’s important to focus on the quality of the underlying business.To do this, I’d recommend keeping an eye out for companies displaying business resilience despite the unfavourable trading conditions. More often than not, such companies tend to generate strong cash flows and sell goods and services that are valued by consumers regardless of economic circumstances. This means that they’re better positioned to ride out the temporary market downswings.Make a millionOnce you’ve bought a handful of diversified shares in good-quality companies, it’s time to let the wonders of compounding returns take over. To illustrate, let’s say you achieved an annual return of 8% on a monthly investment of £500.

You never know, they may not stay cheap for much longer. In any case, if they fall further and the stock market crashes again, I’d see it as another opportunity to buy at a discount and hold for the long term.
