NEW YORK (TheStreet) - Investors' belief that the Federal Reserve won't reduce its bond-buying program in December may lead to a year-end rally.

Since inflation remains low and central bankers appear to be committed to keeping policy accommodative, it looks as if investors have begun to price in tapering in March, which should mean more money flowing into equity markets until then.

It is, of course, easy-monetary policy that has allowed markets to achieve their current lofty levels. During the entire ride up, analysts have called for a pullback, but a considerable pullback has never come. Even the volatility created by the government shutdown in October was just a springboard for further highs in November.

As long as central banks limit downside risk, equities should continue to move higher. Large investors have cautioned small investors to be wary of getting into equities at record highs, but investing in stocks look to be the only move at this point. Of course, markets could fall if further stimulus comes into question.
