By now those involved in the silver space are likely well aware of First Majestic Silver's (TSX:FR,NYSE:AG) decision to postpone the sale of about 934,000 ounces of silver. The company announced the move on October 14, describing it at the time as "an attempt to maximize future profits." Since then, President and CEO Keith Neumeyer has offered a more in-depth explanation, telling Future Money Trends that it's a path his company has followed before. "The third quarter [of] 2014 was the second-worst quarter in five years. Silver prices are down 19 percent in the quarter and that compares to the only other worst quarter in the last five years, and that would've been the second quarter of 2013 where silver prices were down 26 percent," he told the news outlet, adding, "we also held back ounces in that quarter — we didn't hold back as much, we held back about 700,000 ounces then." He also encouraged other silver producers to join him, stating, "I think it would be a very exciting thing for all the silver companies to form a semi-cartel in a way, similar to OPEC. I don't see why we can't do that — I think we all agree together that the paper market has no representation to the physical market, and I think it makes sense that we would all work together to sell our product to industry. I would encourage all [silver producers] to hold back their silver." What do silver miners think? The vast majority of market watchers have responded positively to First Majestic's announcement that it will hold back silver, but what do other silver companies think of that decision?
