How can I protect my investments from inflation?

Invest in equities
Several studies have demonstrated that in the first stage of an inflationary cycle, equities tend to perform well. Signs of a pick-up in inflation are often the consequence of an improving economic backdrop.
Equities should provide some hedge against inflation, since a company’s profit should grow at the same rate as inflation after a period of adjustment. A previous Candriam study confirmed that economic recovery, and thus sound price inflation (so no deflation of hyperinflation) is generally beneficial to equity’s valuations. The price-earnings of the equity market tends to be positively impacted when inflation is between 1% and 4%.
