BALTIMORE ( Stockpickr) -- Markets are firing on all cylinders again, now that the disastrous scenario of a government default is off the table and federal employees are back at work. There's a lot of runway for stocks to spool up their engines in the final months of 2013. >>5 Stocks Poised for Breakouts This year's rally has probably been the most-hated ascent for stocks in most investors' memories. But anyone who avoided equities has gotten punished with colossal underperformance. After all, the S&P 500 is up more than 22% since the calendar flipped over to January. Last week alone, the S&P cranked out 2.42% gains. So as even the most skeptical market participants begin to grudgingly chase performance in 2013's final quarter, the big indices should get a nice tailwind to end the year.
