Quarter-end: Will the stock rally continue? As we near the quarter-end, investors are trying to determine whether the bull market in stocks that began in October can continue - and if so, for how long? Stocks are up over 25 percent since the October lows, when anxiety over Greece and Europe was running high. Since then, the European Central Bank facilitated two rounds of financing (LTRO), the troika has come to the table with another round of rescue funds and Greece has slashed its domestic spending. In addition to the short-term fix of the European debt crisis, U.S. economic data steadily improved, helping to propel stocks higher. But over the past month, investors have begun to worry that a global slowdown is taking hold, alongside rising oil and gas prices. The combination could impede stock market progress, not to mention sap consumer confidence. The worst part of rising gas prices is that consumers encounter them frequently, but rarely put them into a larger context of their financial lives. Here's an example of the simple math: Gas prices are up $.50/gallon since October and assuming that consumers fill their 16 gallon tanks once a week, they are likely to pay an extra $416 per year, if gas prices remain at current levels. Meanwhile, if the same consumer had $25,000 in a diversified retirement account as of October, he probably made at least $3,000 in that account within the same time horizon. Before you write and tell me that this isn't a fair comparison, let me underscore that rising gas prices are regressive. That means they negatively impact those at the lower income brackets far more significantly than those in higher brackets. Also, those at the lower end might not have $25,000 in a retirement account. Still, it's worth noting that $416 over the course of the year may mean one less medium coffee per work day at Dunkin Donuts. A potential economic slowdown, rising gas prices and sheer exhaustion caused investors to call a timeout last week. The Dow and the S&P 500 had their worst weeks of the year, which isn't saying much, in a low volatility environment where stocks have enjoyed swift gains. DJIA: 13,080, down 1.1% on week, up 7% on year S&P 500: 1,397, down 0.5%, up 11% on year (snaps 5-week winning streak) NASDAQ: 3,067, up 0.4%, up 17.7% on year April Crude Oil: $106.87, down 0.6% on week April Gold: $1662.40, up 0.4% on the week AAA national average price for gallon of regular gas: $3.89 (up from $3.61 a month ago) FACTOIDS OF THE WEEK: Millionaires (Source: Spectrem Group and IRS) Maybe you're like Cole Porter and don't want to be millionaire (h/t "High Society"). After all, audits for big earners are on the rise - last year, the IRS audited 12 percent of returns for those who made between $1 and $5 million and 21 percent of those who made between $5 and $10 million.
