From oil to copper to corn, commodity prices have collapsed in the past year. Scott Colyer, CEO of Advisors Asset Management, said the negativity toward hard assets is exactly why investors should start legging into energy and mining stocks. 'Inflation is highly correlated to commodity prices, so at a time period when 27 Central banks around the world are easing and trying to create inflation, I don’t think I want to put myself in front of that move,' said Colyer. 'I would try and be properly aligned and congruent with what they are trying to do.' Colyer added that he starting to see insider buying at commodity based companies as well. He pointed to insider purchasing this week at Southern Copper (SCCO) as an example. Shares of Southern Copper are down over 21% in the past 12 months. 'When insiders take their checkbook out and there is fear in the market and they write checks to buy stock in the open market, I think that’s compelling and I think you have to pay attention to that,' said Colyer. China has been the world’s biggest buyer of commodities in the past decade and the slowdown in the country’s economy has clearly impacted the market for hard assets, and is currently shaking up its stock market as well. The dislocation in China’s stock market is currently being felt here by U.S. investors, yet Colyer said domestic markets are overreacting.
