Fintech startup Riskalyze believes that when investors’ portfolios more accurately match their risk tolerance, they will make better decisions. : Buying low and selling high is the way to profits for investors, but too many people instead do the opposite and hurt their returns because they cannot not stomach market volatility. Riskalyze, a fintech startup, thinks there is a better way. Its technology assesses an individual’s risk tolerance in a more fine-tuned way than simply categorizing them as aggressive or conservative investors and allocates their assets accordingly.
