NEW YORK ( TheStreet -- Don't believe the Federal Reserve when it says inflation is low because prices are indeed rising. Gasoline prices are up 70% over the last three months and overall energy prices have jumped 34%. Food prices have been climbing as well. If you're a farmer, that's great news because the prices you were able to get for your crop rose 36% year-over-year in the fourth quarter. If you're headed to the grocery store, it's not so great. The Federal Reserve will tell you that these rising prices are a sign that "QE2" is working and that deflation fears have been defeated. Janet Yellen, the central banks's vice chairwoman, said in a Jan. 8 speech that inflation has trended downward. But Fed officials tend to focus on core inflation, which excludes those pesky "volatile" food energy prices. This exclusion dates back to Richard Nixon who asked his Fed Reserve Chairman Arthur Burns to come up with a new inflation number to hide the real number. This was after the Vietnam War and oil increased 200% and inflation was 8%. Americans didn't believe the faked numbers then and you shouldn't buy them now. Investors need to be aware of these rising prices and make portfolio decisions accordingly. The long side of the inflation trade is energy. If the prices are rising, energy stocks and ETFs will rise. However if food prices are rising, investors will want to avoid grocery stocks and the shares of other food price-sensitive companies. Many of these companies have already stated that they plan to pass on price increases to consumers over the next couple of quarters. Margins are sure to be impacted as well. Here's a few names that TheStreet's Research team has sell ratings on.
